solar panel in Malaysia cannot ROI.
by the time you ROI your money , your battery and panel will require replacement.
Your total investment is RM47,000
if each monthy you save Rm1,000, that is 47 months .. close to 4 years but your battery will degrade over time and solar panel efficiency is also reduced, you won't be saivng Rm1000 each month.
According to friends in Japan who frequently have earthquakes , they do suffer frequent power shutdown. Their solar panel is for emergency . not to save money.

If u add a micro on top of the string, u are basically paying for a new system.  But if ur intention is just to add another inverter and 4 panel, getting a micro from the beginning will help save the process and wiring.

Hi k/

I installed solar panel for my house 4 months ago. Total cost RM47000 for 26 pcs. Don't know the detail much cos not important to me. All i know is they write Jinko solar 550wp.

So far my average bill from RM800+ reduce to RM40-50. That's a whooping 20% return p.a

Isn't it too good to be true investment? What am i missing? why still not many ppl installing the solar since potential return so damn 7 good. Even EPF give guaranteed 5% only. FD is even lower.

where got battery?

It is just wiring. The old system can use string while the new panels uses micro. Why do you say it is a new system?

Actually I believe they bypass the meter.  With a smaller wire.

So depending on your “saving” like how many percent , they adjust the thickness of the wire.

Coz my friend say that if they “on” the device, the meter will still run.  But whole night only 2kwh or 3kwh.

Just my suspicion.

install solar but no battery ? then install solar for sunny day use ?

This kind very easy kantoi wor if kena TNB spot check, which is why it is very risky.

6ppl 800 ringgit is alot. But my family got 7 also reach 500. Three airconds too. But to get 50 ringgit bill after installing that many solar, i think its not worth it.

47k/36=RM1306 pm.

Put in epf at 5.5%, you'll earn rm4208 interest and will have RM5,1224 after 36 months.


After this 36 months, for the next 7 years, you will earn rm23,989 in interest giving you the total rm75213.

For year 11, you will earn RM4242 interest, translating to RM353 per month.


If you're not able to extend NEM, your PV must offset RM350 pm to break even. Don't forget that your EPF money is still there for you to withdraw, whereas your PV and its peripheral hardware are considered sunk costs and are basically worthless if you decide to give up on it (no/low resale value). Will it add to your house market value? Not sure.
This write-off is not taken into account in the untung-rugi calculation. It essentially means at the wnd of Year 10, your TNB savings is just RM15k (at current tariffs and consumption) more than your EPF balance, but your epf continues to grow while your solar panel system continues to deteriorate in terms of performance and resale value while requiring maintenance.

I hear from kopitiam blow water session that there's this someone who adjust the meter n year ago -> tnb sent letter wanna change smart meter (whole taman) and he normalize back the meter -> tnb lai change smart meter -> readjust the smart meter 

Psst ... he very diam bout this, very the diam unlike those lak kaw bu chiet mouth like a loud speaker.
I hear he's been on the tnb discounted rate for > 10 year. Duno what usage is before but after discount its around Rm150+-

Kasi bakar the meter and get tnb to install new one -> install ur solar.

My monthly bill currently is around RM200. I'm not sure if getting into solar is a worthy venture.

Is there any option if my consumption is just RM200?

Lol don't know why u make it so complicated.
Based on my bill I calculated 20% p.a return for 47k invested.

Epf is 5.5% average.

The only difference is solar panel is physical asset 47k cannot take out but much better return hence the ROI 5 years. Anyway the risk of losing it all is offset by the warranty given.

Epf u can take out but 5.5% p.a. also I already maxing out my epf contribution. I just put 1 year of my epf investment into solar.
Yep. I did just that. The electrician who ahem for me came bc and adjust back. Fucker didn't even bother to replace the sticker. So far haven't kena lawyer letter. Can only pray to God everyday now.

Funny enough before they start change meter I contemplated to burn it and ask for replacement. The guilt and anxiety very overwhelming to me. Very not worth to curi electric

Generally bill below rm400 not worth. The inverter and stuff like that cost significant chunk of the 47k I paid. Also need 3 phase power.

install solar but no battery ? then install solar for sunny day use ?

just to share mine, 800kwh average monthly usage which is RM341 per tnb calculator. Installed a 7.6kwp system for around 28k, using huawei invertor which after NEM could install with its battery system of up to 15kw. Current bill average around rm40, but my petrol bill also went down a bit as I had a phev after solar installation.

No upfront cost but i took EPP for 24month. If the tariff increased in coming budget, then the ROI could be shorter or would be less affected. Main target is to get the bill to using only subsidize rate as i don't see a point to not utilize it, but on top of that I can utilize AC as needed esp. on hot days. Currently I have a 2.5hp running from 8pm - 6am daily.

Quoting from earlier comments, these are money need to be spent anyway to TNB, must as well do something to it and in future get a minor battery for backup in the event of power failure. So, if purely numbers it doesnt make sense, but i'm not good with finance

Noted, thanks. My house is already using 3 phase, and have two mono-pitched roof that is optimally angled towards the sun (annual cycle) between 1030-1700.

I just waiting for solar panels to be cheap enough for me to use...

Actually toward the end the supplier hinted to me they can install extra panel than allowed by TNB, under table stuff. I never ask further since not possible for my case.

I think the main point to be considered. Are u going to shift new house in the next 10-20 years? Is the upfront cost going to affect ur lifestyle. I definitely don't which the biggest reason i go all in for solar.
Hmm... why the need for battery when u already have NEM? How much the battery cost and how many panel? Can last for whole night?

Coz u need totally  new set of wiring? So if u install a micro on top of string, there is nothing that you can use back. It’s like new installation. 

And u need a new db and such.  That’s what I mean a total new system. It is not like u can connect both together.
