Import 1010

Export 983

Extra kwp previous month 70

From app, generation is 1203

So self consumption is around 220

Looks like the solar only managed to cover less than 20% of your usage (day time).

Move some energy intensive stuff to day time perhaps?

Your import still ok. 500 kwh away still from the ICPT charges.

If this 47k doesn't give you hardship and you save RM750 per month in tnb bills, it does seem to be a good choice for you. If you put 47k in epf and assume epf interest of 5.5%, you'll have RM80k in epf after 10 years, compared to 90k in tnb savings.
On paper , you untung but do note that after 10 years if nem is not extended, your tnb savings plunge but your epf continues to earn compounded money for you. That's the risk, returns wise.

However, tnb tariffs may increase over time and your savings will too.

Most importantly, you feel good about it.

Problem is we can’t put 47k straight into year 1. Coz we don’t have the money upfront. Solar don’t need 47k upfront. Just need monthly commitment.

U don’t do solar, the 47 k goes to Tnb anyway. And in fact , over 10 years 90k goes to Tnb.

RM 800 per month is pretty normal.
especially if use electrical kettle, induction cooker and hot water shower.
of course air cond at night in room,
living room also got.

5 years return- yeah good 20% return. Even factor in maintenance/replacement also consider  a good 12 to 15%?
Take note this particular the figure will increase if TNB increase the tarriff.

some say it may not come.... but if the tarrif increase, the contract will at the same time increase the installation cost.
yes better than EPF. Also some bank offer installment right?
*
My bill rm250 max

Living area 2 airconds but very seldom on
3 airconds rooms 12 hours usage daily
Kitchen everything electrical no buy gas tangki
Water heater 3 bathrooms

2 big 2 small

RM800 normal?????? hmmmmmmmm

If rain can clean it how come our exterior wall will still be dirty after years of usage?

Even then solar panel guys been telling us, please clean the panels periodically.

No one is doubting the capability of solar generation but it shall never be glorified and advertised in such a way that it does not come with its challenges.

Read both sides of the stories.

Exterior need clean but not as often or expensive as u think. It's like washing windows. Difficult part is accessing the panel since it's on the roof. They half hint can hire foreigner go up there do "servicing". But engaging them is better cos they go up check the panel etc. But still it's not going to cost more than rm1000.

I actually surveyed a lot since the first roll out the solar package back in 2010. My uncle installed the RM16000 deal back then while i opted for "adjust meter". His ROI is in 6 years and until now 12 years already the amount generated doesnt drop if at all. He said agak2 90%+ efficiency from installation. His deal is perpetual TNB buy back the energy cos first of the first in Malaysia. Main reason why i invest into solar even if it's NEM 3.0

The current trend of oil price. Unless Malaysia go nuclear power plant the electricity price will only increase. Also Malaysia government now more n more ganas against T20, they will 100% go after high consumption household.

What Ts said doesnt makes sense. If your bill is above rm780 or 1500kW.. there will be a surcharge of at least rm150.00 already, and that cannot be offset by your solar export, from what I know.

I suspect it's the amount of light bulb. And also washing machine.

My house semi-D. At night i left some lights on total about 15 x 12w LED light bulb. Probably that's why.

RM400 bill, 17k installation, 24mo zero interest, i just got seda approval for 6kW.

QUOTE(bee88 @ Oct 3 2023, 11:18 AM)
First. There are many ways to avoid the 50k upfront. Many ppl don’t pay upfront lump sum anymore. 

Maintenance try to nego as long as u can

200-300 bill don’t need 50k upfront

Maybe 20k only.

Actually, ur bill doesn’t seems normal. Unless those aircond are inverter and new.

Would be happy actually if I could get the usage like u.

Your usage is just like mine. But mine got la some else like cctv router. Those also take up significant chunks. Water pump. Dryer.

It's because during daytime the solar energy get consumed by your household before being exported away. I also noticed the amount of total electricity consumed on my bill is less than before solar installation.

My guess is family usage? Rental units won't be so high, at least not usually. Anyways, congrats! Awesome result.

Tell your brother prepare 50k soon - After they change smart meter --- they will cross reference check historical usage and current - then 200% kena fine.


With smart meter possible to stikk hack but 100% kena tangkap because they will monitor the grid total usage not the meter only total usage.



Good luck . lol!

Here's an idea, instead of replying here, why don't you censor all the details of your tnb bill so people can see? I'm sure it will take less than 1 minute especially with tnb app

I will be very grateful to see ur censored bill so we can all benefit from it. It's mind boggling for me to say that just because u installed solar, ur KWh consumption became lesser. That doesnt make sense, isn't it?

Maybe is your fridge. I changed my 10 year old fridge, my bill drop average 30rm from 220-250.
Also i noticed if you use air purifier, it is high consumption.
I have similar to both , 3 ac (2 hp + 1hp + 1hp / 8hrs daily), LED bulbs all.
so is quite high if you get 800rm.
