This NEM and ROI is all based on your system capacity. The larger the system the faster the ROI. In short it is huge savings for the rich but little to non benefit for the poor. I have calculated for those electricity usage less than RM200 there is little to no benefits because you need to pay up front and the ROI takes 7 to 8 years and within these period of time, anything happen to your solar panel or inverter is not covered after the initial 12 months.

Why is everyone so sceptical over solar.. am I missing something .
Btw I on nem , this is my  26 months..
I'm using 24 panels and it's really helping me save. Rm 700 bill to rm0-10. However since the past 3 months , I'm paying around rm20-40 each month.
It's not cheap I admit, but wit cc epp 24 months, n it u don't intend to move houses every few years, I do think it's beneficial.

Btw I also gotten myself insurance for solar around300 per year to cover accidental damages to the system.

My only issue right now is, my monthly import is 1100 units and my worry is If I buy an ev, my entire bill will be jacked up due to the surcharge . And charging in the afternoon might not be v feasible for me since I need to drive to office every other day.

Possible to topup 2 more panels? then you will be able to offset the extra load of EVs

It’s 10-25 years. Not 12 month.

String inverter is up to 10 years. Micro can go up to 25 years warranty.
*
I'm not sure what is your contract and warranty as different brand. It will be great if you can share with us your inverter warranty card description?
Based on the quotation and sales agent information, the inverter warranty covered by Huawei is only 12 months... and that does not include lightning strike which maybe common problem depending on ones area.

SST 8% for TNB bill if exceed 600kWh. Another reason to install home solar.

It is charged to those with TNB bills more than RM220 or exceed 600kWh. But for those that uses less, there is no effects.

Yeah... I'm "atas pagar" currently. My bill is around the 600kWH range, some months higher and some months lower. But I did do the necessary basic research and my conclusion is that it is great investment for those that have their bills of RM300 and above but for those with smaller bill, the economy benefits diminishes, but still the good things is one's carbon foot print reduce

Thank you for your information and yeapsc73 information as well.
I understand better now about the inverter warranty of about 10 years. thumbup.gif

I check back with the agent. His referring to warranty more on workmanship and also 1st year insurance that covers lightning...

Guys, my taman has monkey problem - there are monkeys that come into the taman and like to lepak on the roof and break astro dish etc. If I install solar panels on the roof, what are the chances that the monkeys may damage the panels? I have been holding back on solar because of this issue but my bill keeps getting higher and higher.

Consider to install bird spike around the panels? tongue.gif

actually tnb generate the power sure the cost is lower de. let say 1 unit they charge you 0.516, probably the cost only 0.1 only. So you pay the 50k for example la, so they also benefit a lot adi. Most important is how long that thing can last? of course nw they can promise you all the moon. This one need you to tell us after 12 years.
*
In this discussion context, the cost of electricity generation is not in concern because regardless of the cost, the electricity tariff is set by the government + Tnb. Even if their cost is free or if higher due to high fuel price, consumers still pays the same tariff.

The important question is can us consumers benefits from the NEM or so call solar project.
The answer is yes or no (well depends on ones energy consumption), the more energy you use, the more saving you get back in a shorted time. For those usage less than RM100, don't bother at all.
Something like the rich use credit card spent and get cash back/rewards point + delay in repayment... the poor pay with cash get nothing.

As for how long the system last can last? All NEM package is only 10 years contracts. After 10 years there is no obligation for TnB to buy your electricity even if all your equipment is functioning. So the ROI needs to be fully recoup within 10 years else it is consider loss

Cost is always concern because tnb alwasy must maintain the profit or increase it. So no way can let you so nice cheap electricity if you can afford larger solar in long term. Based on their billions profit yearly with tremendous electric stealing still can maintain so high profit can infer lower cost.
*
Haha.. if that is what you think then no way to proof anything already. Since you think TnB makes tons of money and will not rugi... You should invest Kaw Kaw in TnB stock tongue.gif

As already mention, one cannot do anything about the tariff, unless you are PM, I bet TnB CEO also cannot suka suka change the tariff.....

What we can do here is to play the game within the tariff. The solar project is good for those that uses the higher part of the tariff... that just that....

Whatever le if dun believe lower cost. Problem is if ur machine got rosak at year 12, then will u buy again at 80k?
*
Even if I believe you... I still need to pay what the tariff TnB charged me.
The problem in discussion here is, if one can recoup his investment in 10 years time... No need to say until 12 year... Generally let assume that the machine become of 0 value at year 10 due to NEM contract lapsed.

probably enough for me now as my import from TNB is about 15kwh a day and my generation is over 25kwh a day. will get cheaper over time as i read news saying CATL is cutting LFP battery cost by 50% this year. So 14kWh battery may cost less than 3k in 10 years time just in time when my NEM period over
*
That will be the 10 years later question. Currently I think that there is no point of thinking about it for those that looking into NEM it is irrelevant as of now.

I don't support his rationale of not installing solar but it's true in a way, my neighbour have to cough out 10k to change 12 miserables  360W panel because the original FIT supplier already gulung tikar & since he still got 10 years of income it's still worthwhile to change.
*
Yes... this is a very good point.
The warranty provided 10 years or performance warranty is all bound by the solar installer.

If the installer gulung tikar, can only pray that nothing happen to your system.

This is also the main point that GSparx agent remind me when I ask them to quote. He frankly tell me that the price he provide will be higher if compare with other solar installer. But he guarantee that it won't close shop.

Quite a number of solar company setup and close shop, so interested consumers really need to consider carefully.. if it is much cheaper and the panels and inverters are from reknown brands... then can consider, else have to ask oneself the WhatIf question. cool2.gif

Jus to tell u your perception about roi is not reliable je since u wont know the real cost as they have plenty of power backup. I believe they can sell u that price because they generate the power themselves. If the users are getting alot sure that solar panel price will increase also.
*
So what will you suggest to be use to evaluate as in your opinion you think that ROI it is not reliable?

For common consumers... the tariff... which can be tracked all through the years is easy to understand and can be use fairly easily to know if one earn or loss from his Solar project. That will be the predicted ROI.

Of course you are not totally wrong as the ROI is calculated based on current and previous tariff which is predicted to constantly increase. But who know suddenly there is a new oid field found and oil price drop dirt cheap and electric tariff follow suit, or some mad scientist suddenly able to produce electricity out of thin air and electricity tarif price drop rendering solar ROI to zero.

How you check how much ur solar generate the power per day? Is there something like your smartphone can know the percentage of your battery? If not then you just don't know ler since tnb install all for you only.

If private company its very risky and expensive as they can anytime close shop and then open a new company again
*
Actually there is an app to check. The inverter can now do such things... if you don't trust the report by TnB. It is also possible to measure the PV generation.. using power meter. Maybe you can check with solar agent and ask more question... but generally the monitoring part is there.

Fit not 20 years? He told me panel is 10 years old FIT still another 10 years to go so it's worthwhile to change.

Yes currently getting 1/2 of original capacity so I think ROI maybe 3 years but if performace consistant from 4th is pure profit!

Accroding to google, FiT is 21 years
https://www.seda.gov.my/wp-content/uploads/...iT-Brochure.pdf

But back then PV system is expensive, so despite the RM1.49 FiT, The ROI is expected around 7~8 years

Then take video show the power meter here instead of all just words. If cannot accept criticism why open thread? We are now accessing evidence not just words.

Hmm... the request now become strange, maybe can do a bit of homework first regarding FiT.
Of course it is welcome to discuss the pro and cons, but do discuss on technical points not like, picture, then video, then description/contract/bill proof. Most of this can be google from the internet and is already available.

I myself is also not a 100% believer of Solar at least not for my current electric usage level. But don't la until need others to spoon feed information. Cheers mate...
Lets discuss more on the technical part of its benefits and potential risk...

Previous post about solar installer is a very good point about the risk.
Some also mention about animal/pest disturbance which I think is also valid.

For some country that has hail, it is also a problem.
Previous PV panel have temperature issue as well where efficiency drop greatly on hot weather... but I guess it is no longer a big issue now.

Let's discuss and look into more of this problems or benefits. flex.gif

Okay. Let’s address your question

In the first lesson, we learn that the nett offset is 0, so your question is how come Tnb say need to pay rm60.

The website you are looking at is a calculator. It will generate estimated figure based on certain formula.

So where does the rm60++ come from?

In your bill, you have sst charges 6% on 601 units and above.  Icpt surcharge for 1500 kwh usage. Kwtbb 1.6%

What NEM allows to offset is the base fare, but the sst charges , icpt charges , kwtbb are not offset Ed. So the RM60 is actually all the other charges that is not offset. Tnb just offset the unit price, but not others. 

So, u might think, like thst not so worth la kan.

If u no solar, these charges u need to pay. If on solar , you still need to pay.

So these charges are not avoidable whether on solar or not.

Anyway, Tnb calculator x boleh pkai one lah. If suddenly u change ur mind and want to install solar, pm me, I personally help you calculate and offer you sound advice on how to go about installing solar.  There are things to avoid and things to do when it comes to solar. 

Gspark is one that u should avoid in the first place. Like u said, gspark is subsidiary of Tnb and surely Tnb will play kaw u with their gspark package. 

Any more question? Before we can proceed?
*
Good information on everything.... As for the Gspark charge Kaw kaw, that I will beg to differ. I gotten 3 quotation from GSpark, and 2 other companys... GSpark is more expensive but in the range of about 2~8% in my case.... I think for those considering NEM, do weigh and consider and get few quotation as it is free quote. In my opinion I think it is fairly reasonable to pay the extra to have a piece of mind unless the other company reputation is also very good and you personally know that the company is operating for long times. This is just my opinion

Most buyers usually will lowball you on that!

Depends on your inverter brand & it's efficiency ratings.

First time I hear somebody saying Gsparx is good actually! Anyway some company in fact will only do 3 phase 10kW up. Labour & their time to do a bigger system not much difference so with market throwing prices it's just not worthwhile for the smaller company to do single phase 4-6kW. Anyway if anyone would like to do it more economically but you might need to spend some time to study the system yourself can asked me.  Like buying your own panels/inverter from China and getting NEM vendor to endorsed it.
*
Yes, maybe the system I requested is small, so I really see no big price difference in price.
And the problem about solar installer close shop is really rampant. The few that come to my place to quote is all youngster just join the company less than 2 years. Maybe it is a different story in KL. Not to mention the installer, local solar installer all jump from 1 company to another, some are like sub-con to another company. laugh.gif While I also encounter mostly foreign worker and the young sales agent is the only local.

For those that are interested, compare, study and compare... that is the only advice. Sometimes if the price is too good to be true, then have to ask yourself how much risk you are taking. By the way, most established solar installer is located in KL, so the price war is a different story once it is out of KL region.

My opinion is that install solar just don't expect to use it for more than 10 years. Just have the mindset that after 10 years, you need to re-invest. Start from 0 and buy everything again (new inverter + new panels + new DB + new cables maybe + new battery maybe). Then you can work your planning backwards easier.

So the question then become in 10 years time can you can back your invested money?
