had my home solar commissioned in Dec2023 so last month was the first full month generation and usage, summary as below:-

1) System Capacity - 7.2kWp, micro-invertor
2) Cost - RM23k, on 48 months EPP
3) Generation in Jan 2024 - 714kWh
4) Export to TNB in Jab 2024 - 525kWh
5) Own consumption of solar energy - 714 - 525 = 189kWh
6) Import from TNB - 557kWh
7) Total energy usage - 557 + 189 = 746kWh
8) TNB bill if no solar - approx RM315
9) TNB bill with solar - RM3
10) Saving - RM312/month
11) ROI - Around 6 years (23000/312*12)

For my consumption, actually a 5kwp system is sufficient. But i was quoted about 20k for that so for a little bid more, i opt for a 7kwp system. This give me flexibility to add another EV for the family in the near future.

install on sept 23

bill before install.. around 800

bill after install.. around 20-40

daily can get 3-4 hrs peak sun.. 11kW..

if you pay cash that good
if you pay CC (based on TNB website up to 36 months )
u need to pay rm1284 per month for solar installation & equipment installment 
but after 36 month you will happy pay around rm40 to 70/month for electric 
mostly Malaysia people can not afford to pay 1k++ for now.
but in k i sure can affrod one la all k salary 20k permonth   

but if got loan bank up to 10 years,
i believe many people will install solar panel

Roof leaks are the worst effect, all savings let contractor walop fix leak

installer will bear the cost, got warranty ma.

NEM 3.0 here, almost 3 years (2y11m), ROI RM26852.02 ... cost RM38k. zero maintenance cost or malfunction or others.

Tesla 180k
Solar system. 23k.

Pre tesla and solar system 550 myr.
550 x 12 x 10 = 66000 myr.

Bank loan interest at the end of 9th year for the tesla 43,740.00
Solar system repair and maintenance after tenth year? Not sure how much.

Bro u sure u saved money?

Pm u later.

To sinplify things.

U have two meter. One for energy consumed. One for solar generated energy.

(Energy consumed) - (energy generated) = nett difference.

If u generated more than u consumed. The extra will carry forward to next month and so forth. But it will be reset beginning of each year (31st December) .

All excess energy will be exported to grid which will be recorded in ur tnb bill, must use within 1 yr
Tnb wont give cash money  for the energy, only recorded as a credit. After 1 yr, credit back to zero.

This one all my credit burn. Simply put, January start from 0

My Nov extra also gone.

No more selling back. Only accumulate as extra kWh for 1 year period.

Another installer quoted me Solis 3P6K, has integrated AFCI but needs activation, whatever that means. Huawei I know confirm it is there. Between Solis vs Huawei, I prefer Huawei simply because it is a more expensive hybrid inverter versus Solis..so for the same price or less, why choose the cheaper Solis? The company that quoted Solis said I need to top up RM2k if I want Huawei. In terms of company backing, as above, Huawei is one of the biggest tech companies in the world, the backing is solid. Solis, not sure if the company is here in MY themselves or via distributor.

Anyhow the installer quoted me Solis 3P6K with 4.6k panels for more money versus Huawei 5KTL-M1 + 5.4k panels. So its a no brainer for me.
RM18.8k before any rebates.

Well, there are instances micro inverters can be useful, when shading is an issue or orientation/roof design. Mine is a straightforward terrace roof and nothing shading around my roof.

Tis good deal? Using huawei , promotion partner with huawei

solis, longi

edit: can opt for huawei inverter, topup Rm2k

If your bill is rm300, you don’t need this much. If ev is in the planning, but not confirmed, I think better not to take into consideration. Lots of thing can happen within this three years. Newer tech, cheaper options. 

You most likely need about 7kwp max. If you are on single phase, you don’t need to convert to three phase for 11kwp.


Why 3 years time to get ev. Get now and enjoy. Nice ride actually.

i asked already, not Huawei,

is GoodWe GW5000D-NS for 7KWp
