Yeap... My house, we kena RM12k for the penalty... Somemore they start calculating from 2016-2021 only...

Not worth...

had my home solar commissioned in Dec2023 so last month was the first full month generation and usage, summary as below:-

1) System Capacity - 7.2kWp, micro-invertor
2) Cost - RM23k, on 48 months EPP
3) Generation in Jan 2024 - 714kWh
4) Export to TNB in Jab 2024 - 525kWh
5) Own consumption of solar energy - 714 - 525 = 189kWh
6) Import from TNB - 557kWh
7) Total energy usage - 557 + 189 = 746kWh
8) TNB bill if no solar - approx RM315
9) TNB bill with solar - RM3
10) Saving - RM312/month
11) ROI - Around 6 years (23000/312*12)

For my consumption, actually a 5kwp system is sufficient. But i was quoted about 20k for that so for a little bid more, i opt for a 7kwp system. This give me flexibility to add another EV for the family in the near future.

Generated-714kWh VS Usage-746kWh, where got allowance for another EV? Shouldn't u opt for higher kwp?

We enjoy super low tariff for first 300kWh usage. So if my usage reach 1000kWh per month, it is still within the 22c/33c per kwh bracket which is super cheap

Hi. Can I ask you .. since your gross usage is higher than 1500 units.
Do u get extra charged for the surcharge for touching tat level even though your true usage has been brought down by solar ?

I'm also using solar system now. My usage is around 1300kwh (gross). And my bill after inport export calculation is around rm40.
My worry is if I wan to buy ev car, will my total bill kena the new surcharge since it touches 1500 since I will need to charge the car at home.

Impor figure if no more than 1500 u will avoid the icpt charges.

charge your car in day time during weekend/off day. Should be sufficient to fully charge the car unless u drive super far weekly

Looking at my previous tnb usage, my import is 1100kwh. So likely I can have a quota of 399kwh to charge the ev car at night right..

Ur tip to charge during daytime is to avoid the 'import meter' from going up right ?

yup. more self consumption, less import

47k upfront with that kind of savings …5 year only break even not considering things might break in that 5 years

got EPP. got warranty

Because during daytime the solar energy is consumed first before exporting to TNB. Means my house consume roughly rm300-400 electricity during daytime.

Can give more detail? my sixth sense telling those company will charge a fee for solar rental and maintenance. They don't charge upfront fee, but they will leech u off every month.

okay your statement very kuat bau tongkat. lol

short answer. I heard TNB don't want the electricity to fluctuate too much, solar is volatile depending on the weather. Too much energy generated they have a hard time regulating production vs usage. Ideally they want to keep the production as efficient as possible, to prevent wastage. The main reason why they limit the solar generation to your monthly bill. This also serve to prevent ppl to install solar in empty houses for the purpose of passive income.

When u install solar there is two component that cost u money.
- solar panel to collect sunlight
- inverter to convert solar to usable electric.

The panel is relatively cheap when compared to inverter. So when u install solar system. It's recommended to sumbat as many solar panel as possible for one inverter. What i want to say is the system generation is not decided by how much u want to generate. Instead it's how many solar panel ur roof can handle, then u choose the number that a single inverter can fit.

The supplier will guide u in this.

Apparently u wil need to pay two bills instead of one. One to Tnb. One to solar companies.

When u total up both bill, ur saving is about 10% of ur existing / supposed to be bill.

Unless you are very very big consumer, like few thousand units, the saving is negligible. U are better off paying ur bill using credit card and get 5-10% cash back straight.

figured. haha.

But many will think 10% "free money" better than nothing.

A Meths Lab maybe ??

Soon this will be removed, solar users will not be entitled to this. The subsidy is meant for poor but rich are benefitting from it!

If they remove this, it doesn’t affect much. Any increase in tariff is welcome. Coz it’s across board. Poor will be affected too. But for solar user, The roi will be faster. Now it’s the bullshit icpt charges that they manipulate to punish solar users.

Total damage is more than that. Coz installation fee is at least 3k. So total is 15k. If divide by 6 years, it’s rm208 per month.

Actually, it depends on usage and ur single and three phase of your house. Too many pnels , u sendiri rugi coz over generation.
