so conclusion now is. tnb literally backstabbing all solar user?
because planning to get a BEV soon.
mean my current 300kw (without AC and that EV) usage not worth on solar previously, now it lagi not worth?

Does your BEV support V2H, n allow it to function as BESS?

Meanwhile, the CREAM programme allows small-scale solar (like rooftop panels on homes) to sell excess power to other users via the grid.

I thought about buying an Ecoflow with 1kWh to cycle it thru daily to reduce the import by ~1kwh per day. the price of the thing is close to RM4-5k(if got discount).

1. need to figure out what would need up to 900wh thru the night, and need to schedule it to charge only during day time.

2. after thinking a while, probably not worth it.

3. Perhaps I need to do a transfer switch, and just manually power the Vehicle to home - to say power a fridge and or a freezer. even than it is just less than 1kwh per day... per month is just 30kwh??

What about getting a used EV with V2H as BESS.

Rm12000 subsidy for >6kWac solar panel system.
6kWac is 10 x 6kW panels? So pay only RM8000?

the only good thing is they never chase u to make payment
what is bad about them:
1. workmanship very bad as they outsource to 3rd party installer then the 3rd party installer further outsource it
2. due to multi tier outsourcing u need to talk to 3 different ppl from different company to get things fix
3. the db box provided by them is worst than the one we seen in low cost apartment and it is so small - if u want to upgrade in the future it wont work
4. ask them about string vs micro - they say they dont like micro only do string
5. after sales - sucks to the max as never really answer question, ask them question have to wait 3 days baru respond

conclusion - dont go with solarvest
*
What.!!, a listed company doing that.

But one thing about the saving under this / atap is not fixed or predictable like nem.  Just need to be aware of that. Overall the saving would be okay.

If ROI takes 10 years then don't think it is worth it. I tot gov is promoting renewable energy that would help data centers & EV industries n reduce dependency on electricity & petrol subsidies, mana tahu allow TNB to take one step back. Those smaller rooftop solar companies would have a hard time to sustain.

System nowadays is much cheaper, 12.4kwp system around 45k EPP with 32kwh battery.  If cash term can negotiate for a few k more discount. This is enough for 1200kwh usage per month.
*
How much is the 12.4kwp system without battery?

Before discount and cash rebate. Depends on your nego skill

So a difference of 51-32=19k for the 32kwh BESS.

I dunno lah buy more in a package got discount mah. Some more is micro vs hybrid inverter cannot compare also

Also the description of the system also a bit puzzling saying got micro and hybrid

Why TNB's ATAP program on 1 Dec 2025 gives less financial  incentives to home solar adopters, eg ROI of 8 years or longer, ... and encourages the install of Solar with BESS/battery storage, .......

MY has only <5% of energy from solar unlike Holland lah. Stupid decision to slow down rooftop solar adoption. Probably TNB wants to target on big solar private projects.

Hybrid inverter size?

Battery cell price already gone up 10% in China but I think local complete unit price will be absolved by importers so don't expect it to go down much.

EV battery price expected to drop by 70% by 2030, BESS should drop too right?

Seems you are the first person (and a solar installer.?) on this thread asking me this question.

I have not installed the costly solar in my landed home because  my monthly TNB bill is <RM50 = not worth it bc ROI is >28 years if I install a RM15k 4kWp solar system and my monthly TNB bill is RM50.
