You need 5 years to break even. Imo, it should not be considered as ROI during the first 5 years. Don't forget to add the opportunity cost of the RM47000 you coughed up.

After this, baru can consider ROI.

me wife and 4 ekor anak.

Average 3 biji aircon every night until morning. +1 study room aircon if star aligned and i get to play game. Even my friends and family shocked about my rm800+ bill. I also dunno why so high really.

Servicing need to pay iinm.

Then again as ppl mentioned not everyone's monthly electric bill is RM800

Also if u put 47K into FD @ 3% for 5 years u can get interest worth 7K.

My bro house paid 3K for ppl go fix the meter every month bill just RM300.
Can ON aircond whole day

nice ts, the nicest thing about solar is way less guilt turning on airconds because it's way way more effectice than EVs in reducing carbon emissions.

Yeah i know. But high chance government extend it for another 5 years at least. Even if they don't the 5 years after projected ROI i can reinvest to get battery. Still no rugi and potentially untung.

All in all even if government remove NEM i still looking at figure close to FD.

5 years ROI, quite good if there is no additional charges and can run another 5 years.

How about repair and maintenance?

My bill monthly around 70-80. Then mau pasang kena reject. 400 above only can consider. Aduh.

My friend just consider change from this to solar.

He said not worth the effort to adjust meter. Everyday live in fear.

that's very good returns.
recently i installed too. 11.5Kw. 47K MYR in total. but averaging only around 600-700MYR per month. my bills decrease from 1.7k to 1k on average now.
as wife is petronas employee, our warranty is extended to 25 years on panel, inverter, and wiring.

after 10 y cannot renew?

my tnb bill average 40 ringgit only

if i install this, would it generate money instead?

Saving = RM 750

RM 750 x 12 months x 10 years = RM 90,000 (consider your panel doesn't degrade at all, no maintenance needed at all)

RM 90,000 / RM 47,000 = 191% for 10 years.

Let's calculate the CAGR

1.91^(1/10) = 1.067

Meaning 6.7% Compounded Annual Growth Rate (Again, with no solar panel losses, no maintenance needed, no solar seasonal pattern). That's the absolute max you can get for 10 years.

After 10th year, you needed battery to make it viable.

You can renew, buy new set of panel, new installation again.

For my case, I calculated very detail and found out that 6 months usage, I already save about rm3800 worth of electricity.

So yes. If got extra money and Tnb bill high, migh as well consider solar.

Money put in Fd can’t even help u cover your monthly electricity bill.

For my case, there is no upfront payment. Meaning no need to pay lump sum. So even more worth it.

TS farming cow in condo???

you seem proud of your bro fixing meter?

Definitely worth if you can afford it. Problem is most people cannot afford it.

But u must understand, we don’t need to cough up 47k.
That compound interest is when u have 47k upfront.


We just need to pay monthly as usual for 5 years. Actual Tnb usage. And next five years total free.

Yes. On paper. But cannot cash out. Hahah.
