I'm getting 32 to 34 kWh yield for 2.5 hours per day due to current weather now.

Mine is about 1200-1400kwh usage monthly.
Right now , for me , these  10 years is crucial to get the system for free first. By 10 th year, my battery should be free too, covered by the savings from 5th year onwards.

You installed with battery?

previously was even longer to ROI 10+ years...
As you wait longer the price of solar cell drops, competition will drive down the price, ROI will get shorter. that's normaql.

should drop below 10k already for teres

Solar installation, the earlier you adopt, the better, last time FiT, ppl oredi earn kaw-kaw, that time the price was very high, and ROI was around 6 years. Today, their FiT income can pay for monthly car/house loan.

Now is NEM, depending on your consumption, the ROI is between 7~10 years. Contract period is much shorter than FiT.

As of July 2023, there is the ICPT adjustment (calculated before solar offset) that will hurt consumers:
- less than 1.5k kWh, rebate -0.020 sen/kWh (usage 1500kWh = RM737.50)
- more than 1.5k kWh, surcaj 0.10 sen/kWh (usage 1501kWh = RM924.69)

No. There isn’t a battery to worry about. It’s under NEM, so Tnb will take the excess generated and give back 1:1 offset at night.

but november macam haram, everyday rain.. so bill is around 90.. kns

I've a friend who is certified ASHRAE and Energy Manager, he advise its not worth it now to get solar installed. Earlier yes.

I've calculated mine, ROI 7 years is just not worth it.
*
As long as under nem, it is okay. With ROI 7 years , you still get free electricity for 3 years. And not to mention, u have a system fully paid for using Tnb money. Imagin if you don’t go solar and pay 7 years of electricity to Tnb just to get electricity. Why not double up the value paid, get electricity and system.

Problem is gomen not giving enough incentive to go for RE, that's why most people don't bother it

Actually incentive is going to be less. Not going to be more.

Look at nem3.0 in California, now they have to pay for battery solution already.


Right now the incentive still there. Electricity is something we will use anyway. So grab it before it’s too late.

Next time, when u want to adopt solar, price of the pnel could drop, but battery solution is still going to make the whole system price going up again.

My current plan is get the system for free first, then next time, only invest on battery. Or sell back , whichever is better deal.

If your bill consistently rm700, should have gotten a little higher. Like 13kwp or higher. Maybe can tambah two more panels? Haha.

no ler, ppl I know who install FiT are the calculative type, and they see the value oredi
some will take solar loan, some use own cash to fund it
I remember last time FiT, Alliance give solar loan at 5~6%, many ppl just take it

got good sunlight months and bad months

if i go bigger then i'd overcapacity too.. and got credits that need to use up in X months

11kw is just nice actually.. i blame coldplay for bringing the rain

Not entirely correct, my neighbor is one of the early adopters of solar use with the FiT scheme. Till today, after 5 years, the ROI still has a long way to go.

then it's worth looking into the maths vs actual

assume commence in mid 2018 (5 years ago)

4kW FiT at RM0.6682 - average 3hr daily, is monthly 360kWh = RM240
I think the capital that time was around 30~35k, so the ROI would be 12 years or less

Hmmm, how did I remember FiT ROI being much shorter... bangwall.gif

No lah, tnb doesn't do that. They only offset during your monthly billing.

I also wanted more Kw, at that time the max is 11.7Kw cause my bill can go up to 1k monthly.
