Hi all,

Installed 12kwp and my monthly is about RM900. Just want to compare the yield from others too. Not sure whether need to clean the panels already since a few years
*
Can share more details? What is the total price , brand of solar panel and type of inverter?

Any recommendation for 1200 to 1400 kwh usage per month?

Is it possible to use a larger kwp system to offset days or months with lower yield?

Actually if u plan long term, this is one thing you should consider. The amount of $$ to cover the Tnb bill after solar usually can help u get a bigger capacity in the first place based on my experience.. Coz every month is different yield and different sun hour
*
Thanks man, upon further checking my actual consumption is from 10XX to 13XX. The higher one is during hotter months. Expected to go higher in the next 5 year as my wife will stop working and stay at home and eventual upgrade to ev

I am considering the time solar as well, it seems too good to be true though. No additional commitment as well as the payment to time solar + estimated tnb bill is lower than current bill. All the saving and even if the solar setup doesnt work after that 10 years, it doesnt really matter as some saving is achieved without any additional commitment.

Maximum time not at home is just 2 week per year that is just around 5xx kwh.

Pro
No extra payment, instead of paying fully to tnb, now mostly goes to time solar and total payment estimated to be less
Maintenance by company
The company most likely still around after 10 year. Time group


Con
Under contract and most likely i cant sell this house within contract period and terminate without penalty

If 3 phase 12kW enough, unless your consumption is mostly after sunset.
*
The consumption is mostly after 5 pm during work days. No one around during day time.

Does this has anything to about export of power generation? I am still a little confused actually.

If you don’t have the credit card limit to utilize to get the free interest loan from bank, or no extra cash for one lump sum, then this kind of subscription basis is the only choice u have. 

For my case, I have a credit card with a limit that I don’t even utilize. So I use that credit limit “ to pay for it lumpsum” But my settlement with bank is on monthly basis.  So the payment for the monthly basis is still less than what I have to pay for Tnb as it is a zero interest loan.  

Like that I don’t need to pay any lump sum or very big upfront.
*
No problem to pay cash or under credit card. The instalment option i saw before was 36 months and it exceed my monthly payment to tnb. My thinking is to preserve cash and to ensure no extra commitment.

Is there any company that offers a longer instalment period option? If the price is the same for cash payment or credit card without interest, might as well just use instalment option.

Home solar must be in demand now as not many actually responding to a quote.

So far i only got a quote from one supplier, 34k for 11kw system, micro inverter ,cash term. Any opinion about the price?

±RM3k/kWp about reasonable range. My surveys ranges from RM2.7k/kWp up to RM3.5k/kWp mostly with String Inverter. The cheaper ones come with 500W range panels, while the mid/upper tier come with ±600w panels.
*
May i know what is the kwp of your system? It tends to be cheaper per kw for larger system right?

Got few more quotes, i think most solar provider increase their price. So this 4k rebate is just giving you an illusion that you save some but in reality half or all of them goes to the solar company

Some people have good experience with PG, one guy i contacted based on forumer recommendation doesnt seems to want to reply and give ridicilous answer and price.

Sudden increase in demand make them dont care anymore, cause too much project and money i guess

Finally getting the package from emit solar, nice that they have a performance guarantee and saving directly from day one and no need to wait 5 to 6 years

Free Maintenance supported for 10 years and easy to hook up my ev charger.

Mind sharing how does the day one savings work?
*
The payment to emit solar is lower than the potential decrease in electricity bill

Not exactly day one, but after the first electricity bill

Interesting sales pitch proposition other than the ROI period pitch.

Payment to emit solar energy = COI / 120 months = X dollar per month

Potential average decrease in electricity bill per month = Y dollar per month

X < Y?
*
It is not a one to one comparison since maintenance is provided for 10 years and my perspective is i do not incur any additional payment per month. In term of cash flow this is the best although i have no problem to buy outright

While people who buy need to pay more per month if under installment than the decrease in their tnb bill and we havent even included other stuff such as maintenance

You better check your meter reading, i was verbally warned by the installer on installation day and follow up reminder by watsapp message not to turn on solar box until TNB install import/export meter. If want to turn on also for a while only to check it functions.
*
Technically the system is set to zero export although i am doubting that the system is 100% accurate and some would be exported, i have no issue if this doesn’t impact my meter reading (e.g: regsitering export as import)

Do u have a special clamp link to the inverter for this zero export?

I guess so otherwise how is it doing this. It is almost matching my power consumption so far since around 930 am

The installer also mention about the system has its own meter that adjust the output for zero export

Anyone knows how long does it take for tnb to process the nem application? Seems like my meter is already bidirectional so i am not sure what is the delay.
