Unless yr house got a power wall to store extra electric, solar panel is a scam. In theory it will take 10 yr to pay for it self, but ask yr self this question when yr house hold use more electric day time or night time? Night time solar panel working? Morning extra electric go to where? Ludwig., SuperGampang, and 1 other liked this post

SOLAR PANELS deteriorate after a few years. Dont expect the solar panels to be as efficient as it is like on the first day after 4-5 years. The Battery also deteriorates after a few years...and they wont be able to hold the charge long. It is an expensive route to take. Dont bother. nightzstar, smon80, and 4 others liked this post

QUOTE(acbc @ Nov 9 2020, 01:07 PM) If power consumption is low and the solar is able to offset the power bill entirely the solar power is not fully utilised and selling back electricity to TNB is usually at a lower rate, it will have longer ROI.If power consumption is high, then the solar power can be fully utilise, provided the panels are facing the correct direction and scrub wash every 2-3 months for maximum generation efficiency. Without batteries, only power consumption during the day can be offset while residential power consumption are usually higher at night with the A/C switched on. Having batteries will help offset daytime generation to night time consumption, with added cost of course but it will allows better utilisation of power. nabs2205 liked this post

did consider, but risk is too high, not worth the effort. if everything according to plan, it takes 10 years to ROI. and there is no perfect guarantee it will last 10 years, and how much longer it can last after 10 years. cost of the solar panel will keep decreasing and efficiency of panels will keep increasing, in short, the later you install the faster you cover your investment. like maybe 5 years from now, it only take you 2 years to recover your investment(just blindly guess). major part of the investment is the storage, aka batteries, if you able to strike a deal with tnb, allowing you to connect your solar into tnb(reverse the meter when your solar generate more than your usage) and without batteries, it can be alot cheaper, lesser problems, and more worth it. technically still not a good investment for money, unless you have so much money and no where else to spend, better dont do it, price of electricity in malaysia isnt that high yet until you need to do that, if 1 day our electricity cost double, then your ROI will shorten, then you can reconsider. tokdukun, Supreme1394, and 1 other liked this post

A lot of people talking about something they don't even know. All of the excess solar power during daytime will go the TNB grid. The inverter only works during daytime. You will use the power from the grid at night. This excess power can be rolled over for the next 2 years. It is definitely good for long term. Bulan bulan bayar tak sampai RM 20. Tak tau tanya. Kalau bodo sila simpan sendiri. maeve, clement5949, and 8 others liked this post

It was more worth it when there was the Feed-in-Tariff (FiT) scheme, that scheme you can sell back to TNB at high margins. with NEM scheme, sure you can recoup your investment, but on average it is about 7-8 years. Might as well wait a little longer until 2-3 years from now once battery storage price / kWh becomes way cheaper. now you install solar at your house(residential), its like catching falling knife in my opinion. but if you install for capacity at larger than 50kWp, it makes more sense economically, you can ROI quicker on average 5-6 years. I work in solar EPC company, anything can direct PM ask. nightzstar, fist_Aileron, and 4 others liked this post

if for household then ok because extra you sell back to tnb provided u have hybrid inverter. for household you dont need solar battery because night u can use back tnb line. 1 1800w solar battery cost as much as a 345w 2m x 1m solar panel. so if you wanna save half the price then dont need to buy battery lo. being setting up off grid solar power for my dad with battery. everything DIY so have to make sure read all the specs. yes solar panel will degrade, but still will maintain 90% capacity after 10 years and 80% after 20 years. you need to do dusting too if solar panel is dirty. for my dad 1kw off grid solar part cost around 7k+ with 4 solar gel battery 1800w. useful for off grid and also during zombie apocalypse Supreme1394 and weissPC liked this post

only useful on sunny day. on raining season, power output next to nothing.
for example, a lot of these solar power projects built by state gov in rural Sarawak but end up useless coz the system cant supply enough power for daily use, and end up collect dust during raining season. |

How much? Depends on kWp lor
Rule of thumb is these days it costs rm4-6k for each 1 kWp...to know how much you need you have to calculate your daily usage |

I got solar garden light. Not bad. Also got tiny solar light that you can buy at Daiso. Not very strong but the ambient is just nice enough. So far nobody bother to steal it.

QUOTE(MrBaba @ Nov 9 2020, 01:45 PM) The sell back scheme long time ago aldy close like 4-5 yr ago, if got extra electric it will discard into ground je. Mal solar seller dont sell battery with it so totally no point getting solar panel. I don't think you know how this works.The solar system is grid tied meaning you are connected to TNB. Under the old system, you will have 2 meters. One for how much you use which you pay as usual and another for how much you generate which you sell to TNB for a pre agreed rate for 20 years. So if you ROI in 5 years, you untung for 15. Under the new system, the meter is 2 way. Whatever you generate you consume. What ever you don't consume is sold back to the grid so your meter will effectively gostan. So end of the month, your electric bill is kWh consumed- kWh generated and then the standard blocking applies. So why is it worth it if your bill is high? You reduce the number of units in the higher blocks. dzire8089, nightzstar, and 3 others liked this post

tomorrow NEM 3.0 open for application.....
i think about mid-teens return (not cash - set off TNB bill) if your bill > RM250. Make sure you get at about RM4k per kw or lower. Ensure its Grade 1 solar panel, and Grade 1 inverter. They'll try short change (curi ayam) you on these two items. i'm not an installer so don't ask me for price. This post has been edited by billyboy: Jan 31 2021, 10:32 AM |

Energy prep is a GOOD prep but don't rely solely on solar as the alternative energy source. Solar parts are expensive and can be difficult to find further down the road.

I'm about to pull the trigger with GSPARX for a 4kwh system for RM20,500.00. Seems like a good price.
Gonna get a quotation for a 5kwh system to see the price difference. Our monthly bill is about 130-150rm. Is GSPARX generally reputable? or other providers are recommended? Going on the TNB/solar site shows a quotation of RM30k for a 5kwh system. |

I think it'll be an overkill for us as our usage is only 450-500kwh per month. Don't mind going up to 5-6kwh system. Gsparx process is quite simple. I filled a form online and got a nice deck with quotation, estimated savings, forms to sign, payment details etc. Very simple and no need to deal with any humans. Seems like quite a few here used them as well. QUOTE(yushin @ Feb 5 2021, 02:47 PM) Based on their calculation its 10 years.But based on my own calculation as I have access to 1% interest credit facility with no monthly repayments needed (lump sum payment at the end with interest), the money will be invested and I target 6 years ROI. QUOTE(feekle @ Feb 5 2021, 02:56 PM) Ok will google them as well. I don't mind paying more for high quality stuff. But it seems very difficult to get quality information on google. If anyone can vouch for any companies with high quality products and service albeit more expensive please let me know. A member has pm'ed me and I will contact more providers to get a comparison. |

If you are planning to move to a new house, you would be shopping for a lot of new electrical appliances. Use LED lights, inverter Aircond, inverter fridge, energy efficient/ high star ratings electrical appliances and using black out curtains would help in reducing electricity bills. We were so surprised our current bill is way cheaper than previous house and majority is due to new appliances that is more energy savings.

so i did some enquiry and found out that the best is to install panel that can reduce monthly bills by 70%. Because if not if the reduction is more than 100% it will carry forward to next bills and if it goes on till end of the year and your bill still negative, come january TNB will not carry forward the balance.

Hello everyone. I want to install for my house, a semi D. My current bill is about 600- 650 per month. Few years back when i was renting an old house, the bill comes up to 800-1000 per month.
I read from here that usually may need about 11-12kW if my bills are about 600-650. The cost is nearly rm54k for gsparx 😩. Will wait for other quotations. Want to ask any of you here who have installed this system, how is your experience nowafter few years of using it. Is the projected savings correct? ANy issues? Thanks |

QUOTE(ichigo_6091 @ Nov 9 2020, 01:44 PM) It was more worth it when there was the Feed-in-Tariff (FiT) scheme, that scheme you can sell back to TNB at high margins. Feed-in-Tariff scheme no longer running? where can i get latest official info?with NEM scheme, sure you can recoup your investment, but on average it is about 7-8 years. Might as well wait a little longer until 2-3 years from now once battery storage price / kWh becomes way cheaper. now you install solar at your house(residential), its like catching falling knife in my opinion. but if you install for capacity at larger than 50kWp, it makes more sense economically, you can ROI quicker on average 5-6 years. I work in solar EPC company, anything can direct PM ask. |

Solar panel is kinda like rich pipu game/hobby.
U willing to spend 30-40k to reduce rm100-300 tnb bills monthly? The battery capacity and panel also deterioriate yearly. After 10 years maybe your solar panel system kaput need replace with new one. |

So far in my fb the most popup brand advertisement is alpha solar, verdant and itramas solarsave
Then there is tnb own gsparx. Not sure how to compare, call all providers ask them to come site visit and give quotation? Some more need to change to 3 phase first, saw some kena 3k, some kena 5k+.. so much difference.. |

QUOTE(max_cavalera @ Nov 4 2022, 10:06 AM) Solar panel is kinda like rich pipu game/hobby. What happend if after 1 years take installment packaage then die ?U willing to spend 30-40k to reduce rm100-300 tnb bills monthly? The battery capacity and panel also deterioriate yearly. After 10 years maybe your solar panel system kaput need replace with new one. anak bini kena tanggung hutang ? Jo_da48 liked this post

QUOTE(darren486 @ Nov 9 2020, 01:04 PM) Folks, anybody installed the solar panel for home? how much is the cost like? and maintenance ? got lubang? Yes. Using it 2 years now. 10kvah/24 panels. NEM 2.0. Monthly bill about RM 5. have 3 AC from 90s. 1 in constant use. Just changed 1 90s AC to 5 star AC less than 1 month ago. Currently my bill almost a month now is like halved previously.Cost of everything 42K. method of finance, depends. There are various methods. Pay full, loan bank, deal with tnb, fixed monthly rate with tnb for few years and then can get total discount. A year, I get back from solar 8k. Expect solar to pay back investment cost in 4 years. From year 5 onwards, save money. Maintenance. None unless your area dusty need to clean solar. Panel warranty is 25 years. Inverter warranty is 20 years. Lubang, yes, but my case exception. Solar panel people think my house got tile roof, but in fact it is zinc roof. There are two mounting brackets. Zinc or tile. So got micro holes. But zinc roof is made in 1980. Old roof already. Changing roof soon, and remount solar on top of the roof. Make sure to tell solar panel installer what kind of roof you have. They will bring proper bracket. On another note. If want to jimat solar, need to use 3 phase. Not single phase. Inverter on phase, either single or 3 phase. I use gsparx. Tnb company. Happy with service. Now NEM 3.0. Not as great as 2.0.

solar panel is a scam... you only put the once you reach 50...

Kindly check the inverter and solar panel brand then you can compare the price and quality. Some brand you can buy direct from supplier and ask contractor quote for installation

guys, i'm considering to install solar, and the intent is to wipe as much but not necessarily in full. at least to get a consistent wipe rather than having excess capacity that is variable in the bill. the bill with aircond running full when there is humans inside, i expect to be around RM300 at least. i don't consider using batteries to avoid unnecessary replacement cost.
(1) what's the difference between 1-phase and 3-phase? (2) if given that there is no difference in electrical usage pattern, is there savings when comparing 1-phase and 3-phase? (3) do i need to change current electrical equipments if switch from 1-phase to 3-phase? (lighting, LED, smart sockets, fridges, ceiling fans, airconds, everything). do i need to re-cable the existing tri-colour inside walls? (4) for solar, is it necessary to switch to 3-phase? or is there cut-off number in deciding between remaining on 1-phase or to upgrade to 3-phase? |

The fact that you're asking this means you don't even know whether your house is 1 phase or 3 phase? Solar and whether the house is 1 phase or 3 phase is totally 2 different matter.

Govt want to control solar panel supply to jack up price and feed cronies. Otherwise, prices could be easily lower by 50%. Why don't allow open market sourcing instead of restricting and over regulating supply? Our Green Minister should look into this.

You yourself wouldn't want to get shoddy products installed for something dangerous as this. |

QUOTE(Oltromen Ripot @ May 8 2023, 12:32 AM) ya, i mean the placement of inverter et al. yes, its hot during operation. the brighter the sun, the hotter it gets. some use an external fan to blow on it to reduce the heat. of course the solar panel itself is necessary to be exposed to sunlight 😅 and optimally that is on the roof slanted southward. the inverter. is it hot during sunlight operation? still in use after sunlight? is it huge? if caged right under ceiling level of porch i.e. still visible to discerning eyes from outside gate, is it a popular target for vandals and thieves? rule of thumb; electronics hot is bad. cool it down. some even over size their inverter. for example a 10kw solar panel system, but use 12kw inverter. this will ensure that your inverter really last its designated lifetime (8 to 12 years ?). nowadays just make sure got warranty for that time period, but really hassle to replace as it might take one to two months to replace (if lucky). heard there is inverter shortage also. good design and take good care of inverter better. so....make sure, good ventilation, cool place with no direct sunlight. no comment about vandals / thieves but the resale value is low. |

Basically its like your DB box, but bigger (~1.5ft x 2.5ft). During operation can be slightly warmer. So need open air for ventilation. Outside as long as dry should be fine.If above ceiling?

QUOTE(empire @ Nov 9 2020, 01:12 PM) SOLAR PANELS deteriorate after a few years. Dont expect the solar panels to be as efficient as it is like on the first day after 4-5 years. No big deal.... Solar panels degrade around 1% a year. They have a lifespan of 25-30yrs.The Battery also deteriorates after a few years...and they wont be able to hold the charge long. It is an expensive route to take. Dont bother. |

I heard nowadays for micro inverters. That is every panel has its own inverter. This solves the ild problem where if one panel is covered by leaves so all the output of ur other panels is as low as the panel that is covered. It’s increase the cost though though kani liked this post

QUOTE(darren486 @ Nov 9 2020, 01:04 PM) Folks, anybody installed the solar panel for home? how much is the cost like? and maintenance ? got lubang? im not an expert, but i have looked into it, and decided not to proceed because of...i is poor.1) if your house bill is above RM200 monthly, solar panel would really help, and is beneficial for you. if your bill is less, you wont see the return until AFTER the panels are dead, so forget it. 2) cost to install can be as low as 20k and as high as 50k. Say your bill is rm500 a month, meaning you need XX amount of kW capacity to be installed, hence more cost etc. 3) Since your house is linked to TNB, you need their "ok" for you to install and sell it back to them. hence they offer their own Solar Panel to you at a price/arrangement. they pay for the "project cost" and you repay them in X years, and your bill went from Rm500 a month to RM 10 a month. gitu la. 4) if you decide not to sell back to the TNB, you spend (say) RM50k, then your bill went from RM500 to RM10 a month, plus during rainy day you take some from TNB, your return of investment might be longer (15 years gitu). So better get TNB's "ok" for you to sell some when you are away from home (working) and generate electricity to be sold to the grid. 5) Now you might be thinking "but bro, aku kerja time ada matahari, kluar rumah time subuh, balik time maghrib, bila nak enjoy matahari punya hasil?" haaaaaa, thats the generating part, your spend RM500 on your bill, but sell RM490....if you dont want to sell to grid, spend a little more for a battery. but get this....MAHAL NAK MAMPOS. whatever you are spending on your solar panel, double that if you want to include battery storage. Conclusion : you need TNB's ok, which is hard now because ada limit of seats, butttttttt.....if you use their subsidiary, they can give quotation and plan for you. Set aside RM50k max. homicidal85 liked this post

(2) if it is excess into grid, is there an amount as rebate? (3) if got rebate, can it offset when i use from grid at night or on weekends? 2.) not rebate, credit. 3.) Yes. |

I've run the numbers if i do a stand alone, (based on my bill), i will only see the positives from the saving after 20 years, since my electricity bill is less than rm150 monthly. so its not beneficial for me, unless TNB yg letak (pay for me) and they give me some electricity for free, and the rest they sell to the grid. but this is the real world, nothing is free. so i dont do it. |

Utilities pay you by way of giving free electricity, if they can use your rooftops. They dont pay lease, they own the solar panels, if they want to uninstall they can. We get free electricity and green. The can sell to industrial and commercial customers, including selling the RE certificate that now everyone wants to buy to say "i is green company". But then again, this is the real world. its not "My little pony" world, where there are rainbows and happiness everywhere. Sigh. |

QUOTE(Oltromen Ripot @ May 7 2023, 07:25 PM) so the "currency" is kW. Just to further highlight, the carry forward portion can only last for 12 mths, if you never utilise it within this period, it will be forfeited. So best is to use your 3 mths bills to come out with average amt, then ask them to advise on ideal number of panel, so you won't underutilise the capacity by paying extra.trying to understand. so for a month period. (1) if usage > generated, i will have to pay for the excess "withdrawal". correct? (2) if generated > usage, i don't have to pay. the excess "deposit" won't become monetary, but carry forward to contra in the future months. correct? |

Just wondering, if I buy a house that claims to be "ready for solar system installation" (e.g. Serenia Anisa), will the cost to install become cheaper? How much cheaper?
Is there something I need to check for when signing S&P to ensure they are not conning me? This post has been edited by imnotabot: May 8 2023, 12:56 PM |

But NEM only last for 10 years, so the sales person only said it have to wait until that time only can know what will be new arrangement, maybe the knock off will start from cheapest tariff instead of highest tariffs under NEM 3.0. So best is to follow their adviser advice on number of board within your usage. Maybe other experience user can enlighten on this. salimbest83 liked this post

How much cheaper? If your house is strata title, the installation cost will be higher, because management office don't allow to install anything on exterior wall surface. Like mine, the DB is at downstairs storeroom, so the cable have to be pulled from roof top to the rear exterior wall and then all the way go into the kitchen ceiling, and continue pull to my DB. So from rooftop to kitchen's exterior wall, I have to ask my own contractor to hack and conceal the cable and repaint the wall surface, it will cost me about 1k, the solar company can do that but usually will cost more. Minor hacking inside the house, solar installer can cover, but I need to do plaster ceiling to cover it, but anyway I will still do plaster ceiling for whole house so this is not counted. Is there something I need to check for when signing S&P to ensure they are not conning me? So if there is no restriction on your exterior wall, you don't need to pay anything. They will put cable in pvc pipe stick on your wall surface. If your house got sub DB on topper floor, then it will be easier, they can just pull the cable under roof tile go into your house connect to sub DB on upper floor, of course you need to pay if you wan conceal the cable inside your house. Another thing is the 10mm cable from DB to car porch for EV charger. I haven't received quotation for this. So it would be great if Sime Darby can conceal all cable inside wall for you with ready points, the solar installer can just come to install, save alot of effort, maybe can save 1 to 1.5k for conceal cost. Just not sure if the solar company can give further discount for hacking and cable cost, since it is included in package This post has been edited by Jingle91: May 8 2023, 01:52 PM |

you only install when you're reaching 50 years...
too early panels wont last efficiently till your dead... also if possible to hold to buy in future better panels is coming out... higher efficiency... |

Roi is nearly 20% pa It’s like rolling Tnb bill money to pay for system that can generate free electricity for 10 years First 5 years money pay to Tnb become money pay for solar.

QUOTE(billyboy @ May 8 2023, 02:24 PM) sounds decent equipment. make sure they don't undersize the inverter....sometimes installer say 8kw solar panel, but inverter 6kw cukup due to peak load spreading. This is one problem. Not only that they don’t tell you how the production can be affected by several factors.sure ok until warranty over, then sure the inverter kaput before due date to over-load. up to you if want to take risk |

QUOTE(Jingle91 @ May 8 2023, 12:39 PM) Thanks mate, you are right, SMA cost 20% more, and I ask ERS to give me jinko board plus Goodwe. Mine also from ERS, almost 2y2m installed already save me RM19.6k. My cost was RM38k back then, extended warranty on my inverter too. Good buy I totally agreed for heavy users.They agreed this morning. This post has been edited by etan26: May 8 2023, 02:49 PM Jingle91 liked this post

QUOTE(bee88 @ May 8 2023, 02:36 PM) when you say efficient, its with regards to shading......right ?personally, i prefer string inverter for maintenance and yield efficiency. Replacing a string inverter is also heck a lot easier. have you also calculated the RM per kw for string inverter vs micro inverter ? huge difference.....micro is way more expensive (on a per kw basis). so......have to provide full picture lah... |

If NEM3 for 1-phase residence is 4kWh;
does that mean i can only install maximum panels as much as 4 kWh and not more? or does it mean i can install more than 4kWh as i can afford, BUT, for purpose of NEM3 i can only export max 4kWh to grid? |

i think for myself. TNB bill on 50~70 (on old meter), new meter probably will go 100~120?
maybe not worth to get basic solar ? house type is roofed corner lot terrace. |

Is there big difference whether the solar panels are P or N type? Apparently N type is 1-2% more efficient to P type.

Except you puchased a backup batter where you keep all the solar power. But not recommend as this point due to cost of the battery. coconutzz liked this post

Solar installation, the earlier you adopt, the better, last time FiT, ppl oredi earn kaw-kaw, that time the price was very high, and ROI was around 6 years. Today, their FiT income can pay for monthly car/house loan.
Now is NEM, depending on your consumption, the ROI is between 7~10 years. Contract period is much shorter than FiT. As of July 2023, there is the ICPT adjustment (calculated before solar offset) that will hurt consumers: - less than 1.5k kWh, rebate -0.020 sen/kWh (usage 1500kWh = RM737.50) - more than 1.5k kWh, surcaj 0.10 sen/kWh (usage 1501kWh = RM924.69) https://www.mytnb.com.my/residential/unders...lling-component https://myelectricitybill.my/bill_calculator_domestic.html This post has been edited by alexei: Dec 5 2023, 09:16 AM |

What we're thought, is that solar price will decrease and duration to ROI will decrease. This was correct, but the ROI heavily depended on the scheme provided by TNB. Last time, RM10~12k/kW now Rm4~5k/kW. Solar price did go down, but ROI was longer.
Moving forward, solar price will keep going down, or the technology gets better. Electricity tariff heavily depends on cost of fuel, and subsidy. Right now, fuel subsidy and electricity subsidy is going to cut. Biggest question will be, what is the NEM to discount ratio? The economics of solar will 'self balance' between solar vendors pricing vs TNB scheme. Otherwise, everybody will rush to installing solar and we end up like Australia. In short, I foresee ROI will maintain between 7~10 years no matter the solar technology or pricing, unless something distruptive comes along. |

Solar and electric cars: right now, electric cars are using ~20kWh/100km (credit Boy96 on his AMA), so that's between RM4.7~RM12.3 per 100km depending on the TNB tariff rates, or equavalent to 2.3L~6L per 100km based on current RON95 price of RM2.05.
Comparing to a car that consumes RM20.50 per 100km (10L/100km), that's a savings between RM15~8.2 per 100km, or 80sen~40sen savings per 100kWh. So, if you move from petrol to electric, remember to include petrol savings into the solar ROI. This post has been edited by alexei: Dec 5 2023, 09:49 AM |

The consumption also varies by car, I'm sure, just don't have the numbersthe savings formula should be simple, such as RM8 savings per 100km Unrealistically speaking, if use the EV and drives 100k km per year (274km daily), the minimum savings is RM8k per year. That's almost ROI for a 2kW system. |

QUOTE(johnnycp @ Dec 7 2023, 07:51 AM) Actually incentive is going to be less. Not going to be more. Look at nem3.0 in California, now they have to pay for battery solution already. Right now the incentive still there. Electricity is something we will use anyway. So grab it before it’s too late. Next time, when u want to adopt solar, price of the pnel could drop, but battery solution is still going to make the whole system price going up again. My current plan is get the system for free first, then next time, only invest on battery. Or sell back , whichever is better deal. etan26 liked this post

which supplier the most cost effective and reliable for 5.5KWp systerm ?
some company offer discount for petronas staff, which I stay away, since they mark up the price for non petronas staff |

QUOTE(bee88 @ Dec 7 2023, 08:36 AM) Ic. got good sunlight months and bad monthsIf your bill consistently rm700, should have gotten a little higher. Like 13kwp or higher. Maybe can tambah two more panels? Haha. if i go bigger then i'd overcapacity too.. and got credits that need to use up in X months 11kw is just nice actually.. i blame coldplay for bringing the rain alexei liked this post

QUOTE(alexei @ Dec 5 2023, 09:16 AM) Solar installation, the earlier you adopt, the better, last time FiT, ppl oredi earn kaw-kaw, that time the price was very high, and ROI was around 6 years. Today, their FiT income can pay for monthly car/house loan. Not entirely correct, my neighbor is one of the early adopters of solar use with the FiT scheme. Till today, after 5 years, the ROI still has a long way to go.Now is NEM, depending on your consumption, the ROI is between 7~10 years. Contract period is much shorter than FiT. As of July 2023, there is the ICPT adjustment (calculated before solar offset) that will hurt consumers: - less than 1.5k kWh, rebate -0.020 sen/kWh (usage 1500kWh = RM737.50) - more than 1.5k kWh, surcaj 0.10 sen/kWh (usage 1501kWh = RM924.69) https://www.mytnb.com.my/residential/unders...lling-component https://myelectricitybill.my/bill_calculator_domestic.html |

I am more afraid if your solar provider didn’t help to apply full quota for your system.
For example, you instal 11kwp panel, they only help to apply 8-9kwac jer. |

QUOTE(bee88 @ Dec 8 2023, 09:02 PM) Regarding warranties, please bear in mind that not all warranties cover everything. Panels may come with a 20-year warranty on performance, while inverters may have a 5-year warranty or less, requiring an extra payment during initial installation. It's essential to consider the warranty provided by the installer, typically around 1 year in older days, with charges for subsequent service. When it comes to panel or inverter warranties, carefully read the manufacturer's fine print to understand what's covered. Claiming warranty in Malaysia can be challenging for end users.I'm quite curious about the experiences of those who installed solar systems in the past 5 years. Could you share any issues faced with panels and inverters? How does the yield after 5 years compare to the first year? |

Guys, if someone bought a house that the previous owner had installed some kind of power saving mod, I think it was at the the meter, will the new owner get in trouble when they want to install solar system at the house? They could not see anything wrong with the meter though.

Based on this actually your consumption 1619kWh (total consumption) - 673 (NEM excess) actually after offset you are not supposed to be charge surcharge
so can complaint to ST(Suruhanjaya Tenaga Bureau) this because ST wasn't aware. I got this news from my Solar installer company just now, they are compiling all the complaints and forward to ST. |

Daytime if you draw more than u produce, then the usage will be recorded as well. So some of the 1619kwh recorded for the monthly usage could be in the morning when system didn’t produce more than own usage. So that kWh is also generated by Tnb using coal , and hence , the icpt charges applies.Usually for daytime, u use ur own production and excess will be pushed back to Tnb.

If your solar not enough than your Export not change but import will change since you are using TNB power due to not enough solar supply |

Have you both experience TNB supply interruption after solar installation? Do you still have power supply? I have even wasted 1 day solar energy cause of that.

It’s not connected to the Tnb grid directly. So it will be self consumption first, then extra will be sent out. This is confirmed. Yes, u need to have Tnb supply to start generation. But that only to start. Once ur system produce enough, u don’t draw from Tnb anymore. Also, one thing to consider. Ur system could be producing 1-2kw in the morning, before it peak, and at that time if u on aircond, maybe ur usage is more than 1-2kw, so the balance they draw from Tnb. But when u peak at 10-12kw during afternoon, and ur appliances only run about 1-2kw, u will send the extra to them. So the net import figure from the bill is from this kind of usage. |

For my case, it will be around 900-1000kwh Where did the 200-300kwh go? This means we have used the 200-300 units. Analogy. Ur farm produce 100 apples. U eat 30. So u can only sell 70. |

QUOTE(bee88 @ Jan 4 2024, 10:39 AM) The solar db is connected to our house db. It’s not connected to the Tnb grid directly. If our inverted can do it, why can't during blackout period? Simply because our inverter cannot cater for direct usage.So it will be self consumption first, then extra will be sent out. This is confirmed. Yes, u need to have Tnb supply to start generation. But that only to start. Once ur system produce enough, u don’t draw from Tnb anymore. Also, one thing to consider. Ur system could be producing 1-2kw in the morning, before it peak, and at that time if u on aircond, maybe ur usage is more than 1-2kw, so the balance they draw from Tnb. But when u peak at 10-12kw during afternoon, and ur appliances only run about 1-2kw, u will send the extra to them. So the net import figure from the bill is from this kind of usage. Show me where its said this "Yes, u need to have Tnb supply to start generation. But that only to start. Once ur system produce enough, u don’t draw from Tnb anymore. " I connect them to my 2nd floor DB ... So my ground floor not using solar energy? They do travel backward to the meter? This post has been edited by etan26: Jan 4 2024, 10:50 AM |

QUOTE(etan26 @ Jan 4 2024, 10:37 AM) I did asked my solar supplier before, we can't used our solar energy directly at this moment because the inverter can't cater for it. No. As long as you don’t have the battery solution, u can’t straight use solar energy. Coz ur inverter need minimal power to start. And it is not stable to direct use anyway. Maybe in the future .... hopefully we can used it during blackout in the day time. That’s why the solar db is connected to home db. And Tnb also connect to home db. Then power come from two ways to your db. If ur solar produce enough, the Tnb just a standby. If not it will top up. Especially in morning. |

The 200-300 of missing export isn’t going to nem Baki. The one went to nem Baki is when my export more than import like a few kWh If you check out nem program , it is defined as below Under this programme, any excess energy generated will be exported to the utility grid and will be credited based on the Average SMP. The priority is for self-consumption, however some premise which are not operating during the weekends or public holiday may have excess energy exported to the grid. |

It can offset the number je..... So once Both ac meets in the home db, it will be used together. But because solar db is one way. And Tnb is two way. So solar db electricity that lebih will flow out through Tnb meter and get recorded. And ur system won’t draw specifically from Tnb. It will just use whatever energy supply from the solar db and the Tnb. So when ur solar db electricity flood the system, the Tnb meter won’t send in anymore. Coz got extra flow out. |

Can we use direct power from solar panel?
Yes, it is possible to use a direct solar panel output to run home AC appliances by adding a solar charge controller connected to a 12V battery. The solar charge controller regulates the voltage and current from the solar panels to charge the battery. |

QUOTE(empire @ Nov 9 2020, 01:12 PM) SOLAR PANELS deteriorate after a few years. Dont expect the solar panels to be as efficient as it is like on the first day after 4-5 years. That's true. Plus you only "break-even" years later minus your installation cost etc. The Battery also deteriorates after a few years...and they wont be able to hold the charge long. It is an expensive route to take. Dont bother. So don't bother. If wanna save just find *cough any elec kaotim *cough ehem. But I do have the solar water heating, now this is best. empire liked this post

Can we use solar panels and electricity at the same time? Yes, that's how they work. Any electrical loads in your house will draw their power from your solar panels if it's available. Any excess power your solar array is generating will flow back out into the grid. If you're using more than your panels can supply the shortfall will be pulled in from the grid. All this happens automatically. You don't have to do anything. You could be correct .... i rest my case. |

To the solar owner, in case you would like to monitor your solar generation, grid, and load in realtime (mobile app only), you can consider installing this bidirectional energy monitor (https://expo.tuya.com/product/1105297 , from Shopee or Lazada). NOTE: This is for a single-phase house.
I will recommend an energy monitor with 2 CT, where the 1st CT (current transformer) monitors the TNB input (as Channel A), while the 2nd CT (as Channel B) can either monitor your load or solar wire (subject to the complexity of your wiring). For simplicity, monitor the solar AC input. Channel C is derived from Channel A and Channel B. For example:- Channel A: TNB input Channel B: Solar input Channel C: Channel A + Channel B = Load/Consumption NOTE: The above works well if both TNB and solar input meet in the same DB box; otherwise, you will need 2 units of energy monitors, for example, one for the TNB on the ground floor and a second monitor unit on the 2nd or 3rd floor where your solar inverter is connected. For smart home users using Home Assistant, this energy meter does not give valuable (limited) data for plotting graphical energy flow between grid, solar, and load. |

QUOTE(Avangelice @ Jan 4 2024, 11:23 AM) So to really ensure my ev is powered by solar and off grid my set up is this? Do a Google search on Smart EV charger and you will find an EV charger where it will monitor your grid export and charge your car accordingly.Solar panels (DC) > battery > wall mounted charger (ac) > ev? If I don't wanna spend on a battery Solar panels (DC) > converter > wall mounted charger (ac) > ev? Second set up only allows me to charge during day time only right? |

below is what the ST Standard for EV charger. It need go out after the main RCCB
![]() Below the ST standard for Solar, you could see solar arrived at the DB and supply into the house before involved the TNB meter (import / export). For safety reasn when house current is cut, solar need to cut as well. else may risk on peoples who do the work ![]() Here another explaination from TNB ![]() Hope this help. |

Hi sifus. I was proposed bifacial solar panel for a tiled rooftop installation. However, based on my understanding, to maximize bifacial gains, you would need to install the panels on an elevated racking system to allow the back panels to capture light. Would I be better off installing non bifacial panels?

QUOTE(etan26 @ Jan 3 2024, 11:13 AM) No, during daytime we also get from the Grid, our solar energy is exported and we import the Grid energy. Hence they offset during daytime but not the night time when we have surplus from daytime generation. The 1500kwhr, if you get it from the grid you will be charged extra. They don't calculate nett Export -Import , they just calculate what you get from the grid. |

QUOTE(bee88 @ Jan 4 2024, 10:39 AM) The solar db is connected to our house db. It’s not connected to the Tnb grid directly. No , you have to consider whether your inverter is a 3 phase inverter or a single phase inverter. So it will be self consumption first, then extra will be sent out. This is confirmed. Yes, u need to have Tnb supply to start generation. But that only to start. Once ur system produce enough, u don’t draw from Tnb anymore. Also, one thing to consider. Ur system could be producing 1-2kw in the morning, before it peak, and at that time if u on aircond, maybe ur usage is more than 1-2kw, so the balance they draw from Tnb. But when u peak at 10-12kw during afternoon, and ur appliances only run about 1-2kw, u will send the extra to them. So the net import figure from the bill is from this kind of usage. Most installer want to sell cheap , and consumers do not know , so they only use single phase inverter. If it is single phase inverter, the inverter will only offset one of the phases. It does not offset all phases. The other 2 phases will not be offset during the day time and continue to consume from the grid. That's why when the1500kwhr ruling came out , some of the solar owners were charged because they were still using 1500kwhr from the grid. |

QUOTE(etan26 @ Jan 4 2024, 10:43 AM) If our inverted can do it, why can't during blackout period? Simply because our inverter cannot cater for direct usage. it's for safety , your inverter is connected directly to grid .Show me where its said this "Yes, u need to have Tnb supply to start generation. But that only to start. Once ur system produce enough, u don’t draw from Tnb anymore. " I connect them to my 2nd floor DB ... So my ground floor not using solar energy? They do travel backward to the meter? https://www.solar-electric.com/learning-cen...to%20the%20grid. |

But installer does not want to provide me with the end user username and password for hoymiles s-Miles monitoring app system saying its only for there own usage.

I foresee the problem will come after the 10-year contract with TNB ended and the owner decided to install 100 kWH of battery to hold 2 days of sunlight energy and then find out that this energy can only be used in one of the electrical phases (e.g., a certain section of the floor), but the other phases have to draw from TNB.In summary, underutilize the battery capacity sized for 3 phases, which can only be used by one of the phases. I wonder if this kind of trick is also practiced by TNB's solar subsidiary. |

QUOTE(eagle7 @ Jan 10 2024, 04:37 PM) I foresee the problem will come after the 10-year contract with TNB ended and the owner decided to install 100 kWH of battery to hold 2 days of sunlight energy and then find out that this energy can only be used in one of the electrical phases (e.g., a certain section of the floor), but the other phases have to draw from TNB. I think no need 100kwh battery. That’s overkill already. Since solar generation is daily. Maybe you just need about the night usage kWh size battery.In summary, underutilize the battery capacity sized for 3 phases, which can only be used by one of the phases. I wonder if this kind of trick is also practiced by TNB's solar subsidiary. |

If I have 13KWac Solar Systems, and able to generate 45.5KWh (13KWac x average of 3.5 Full Day light) per day and size the battery to 1.5 to 2 times of the daily capacity maybe make sense. The battery will last longer if charge and discharge around 30 to 80% of its rated capacity. |

Otherwise I think you can make an official complaint. They die also wont give, say they throw a lot of money develop there stupid app that sync the data from s mile app. |

Can’t even monitor panel performance when the benefit of micro is to allow panel performance monitoring to ensure the panel is working. There are so much data to be obtained from smile app, like total energy per panel per day, micro inverter temperature for safety reason, panel performance at certain time of the day, comparison of panel production to ensure no panel malfunctioning, daily graph, yearly graph, inverter amp, inverter output. All these data are crucial because one off, tecnician should come to inspect. Without these data, u can’t even argue with them. Better go string if only get minimal info.

It’s the right that the customer has for using hoymiles merchandise. |

QUOTE(eagle7 @ Jan 11 2024, 05:20 PM) Correct, they keep the admin login to themselves. Actually they can create the smile end user login credential. I have seen before the installer app and it’s as easy as abc to create end user account. Doesn’t take much time pun. If one day you want the Solar System to use isolated WIFI (IOT/Guest wifi) instead of private WIFI, you need to call them to login and change the WIFI connection for you. The difference between installer app and end user is that installer app can reboot inverter and modify power ratio while end user cannot. And installer app has access to many projects instead of one for end user app. Seen before the interface. This post has been edited by bee88: Jan 11 2024, 11:35 PM |

Is this for real, 1000x better? If yes, can Solar powered EV.

QUOTE(bee88 @ Jan 4 2024, 11:17 AM) U see. You connect to 2 floor db. So the energy source come from 2nd floor. It’s not even direct to Tnb. What is the prefere-able way of connecting the solar power directly to either Main DB or 2nd floor DB? Is there any disadvantages of connecting to 2nd floor DB instead of main DB ?So ur 2nd floor will use the energy first. Then extra go back to main db. And then get istributed to the appliance. Then extra flow back to Tnb. But doesn’t mean ur ground floor will use Tnb energy first. You still use solar for self consumption first before any extra is send out. When cloudy day, not enough producing , that’s when Tnb kicks in. That’s the way how on grid inverter works. |
