I read somewhere the ROI is between 9-10 years.

Unless yr house got a power wall to store extra electric,  solar panel is a scam. In theory it will take 10 yr to pay for it self,  but ask yr self this question when yr house hold use more electric day time or night time?  Night time solar panel working?  Morning extra electric go to where?

How much higher is your tnb bill? solar panel only worth it if you monthly usage is over 600kwh

Installed solar panel for my house.

For warranty:
Panel - 20 years
Inverter - 5 + 2 years
Workmanship - 3 years

Cost me around RM 24K for the whole package. Using Maybank 0 interest 24 month installment.
So far so good. Can even monitor power panel from apps.

did consider, but risk is too high, not worth the effort.

if everything according to plan, it takes 10 years to ROI. and there is no perfect guarantee it will last 10 years, and how much longer it can last after 10 years. cost of the solar panel will keep decreasing and efficiency of panels will keep increasing, in short, the later you install the faster you cover your investment. like maybe 5 years from now, it only take you 2 years to recover your investment(just blindly guess).

major part of the investment is the storage, aka batteries, if you able to strike a deal with tnb, allowing you to connect your solar into tnb(reverse the meter when your solar generate more than your usage) and without batteries, it can be alot cheaper, lesser problems, and more worth it.

technically still not a good investment for money, unless you have so much money and no where else to spend, better dont do it, price of electricity in malaysia isnt that high yet until you need to do that, if 1 day our electricity cost double, then  your ROI will shorten, then you can reconsider.

There a dedicated  thread about the scheme last check the scheme not taking in new application  since 4-5 yr ago dy.

What is the capacity do you need?

I can qoute for 10,000 watt - 20,000 watt full set.
On grid or hybrid system.

10,000 watt can run approx 3-5 nos of  high efficiency 1 hp air conditioner

If maximize usage.
Return on investment 4-5 years onwards.

Wats ur avg bill B4 installation, ur system is how many KW? I may want to install also, my bill about 600

So it will take ~6.5 years to recoup back the cost. Not bad.

any members use "https://www.simplisolar.com/"?
I'm looking at Sols Energy (Backup by Petronas) /  Verdant too.
Comments are welcome.

Need change from Single Phase to 3 phase if need more than 5KW. Any recommend TNB Approval contractors that could do internal wiring too?

Is that included 3 Phase or just the solar?
