1. Standard double storey house.
2. Monthly Rm 400 - 600 / months
3. Wahhhh so expensive seriously.

I thought renewable energy is cheap 😓😓

Need to consider also how long solar panel and batteries can last before replacement.

Yes, for RM 400-600 bill you need 10 kwp setup.
Which is around 45,000.00
Takes 6-7 years to recoup the investment.

But, there is a big BUT, this NEM policy stays valid for 10 years only.
After ten years, you can't sell it back to TNB anymore to offset your bill.

The way out is installing another battery setup (20-40k) depends on cost of the battery 10 years later.

I roughly did my calculation previously,
for 20 years with 10 years of NEM policy (sell back to TNB) and
10 years of self consumption (Install battery after 10 years),
the CAGR is around 5.5%,
which can be easily achievable by putting the money in EPF plus without any headache.

Meaning same amount of money put in EPF, get you same return like Solar Project.

Correct me if my calculation is wrong.

I don't calculate but with solar panel output and batteries degradation, at current cost I'd say not worth it.

Yes, put money in EPF probably generate enough to cover the bill laugh.gif

NEMS policy stays valid for 10 years only.
Panel has 25 years PERFORMANCE GUARANTEE, by most supplier.
-0.5% performance per year, as advertised by most companies.

Risk would involve:
Panel being defective (Few hundred to fix, for material, but you sure you wanna climb the roof?)
Blown inverter (Few thousand to fix)
Leakages due to installation (They drill holes on your roof to mount the panels and did not seal it off completely)

That good now? Well need to get the new panel that generate power from sun and rain too.

I'm wonderign why is there even a battery involved....

If no batteries, how to get power at night? During day, where to channel excess power if not storage. Panel output is DC anyway and output is not constant. The AC is generates using inverter from DC.

I dont need to read what others say about NEM, I'm using it

As mentioned it is only for 10 years, right? After that?

U installed brapa kw? Nem 1 or 2 or 3?

I'm on nem 2.

On side note, the ppl pulling information through the sky and ass is alot in here.

The last I know is u don't need 50k for residential solar installation. Seda only allows a max 12kw installation under nem 3.
50k with micro inverter should be able to get your around 15kw -17kw which seda doesn't allow for residential.

What is the reason for limiting? hmm.gif
