Hi k/

I installed solar panel for my house 4 months ago. Total cost RM47000 for 26 pcs. Don't know the detail much cos not important to me. All i know is they write Jinko solar 550wp.

So far my average bill from RM800+ reduce to RM40-50. That's a whooping 20% return p.a

Isn't it too good to be true investment? What am i missing? why still not many ppl installing the solar since potential return so damn 7 good. Even EPF give guaranteed 5% only. FD is even lower.

As long as there are no leaks, please remember that the water will still flow under the solar panels from the parts left uncovered by the panels.

Nowadays not easy getting people to climb up there for roofing works. Very expensive even if can find sweat.gif

good point. if there is leak under the panel. headache to fix tiles !

electricity is not so much how much you're using
there are different tier on pricing
the more u use, you'll be in a different tier
so if your usage is in a certain tier, it gets expensive real fast

the lesser we use, we're at the lower pricing tier
*
Yeah the tariffs blocks, but my point still stands though. Think of it this way, some of the higher ends residential bill posted here are higher than some SME commercial lots.

Coz my system can monitor per panel production, when I feel the production is no longer there, I can consider to clean.
*
I know, but how often those panels need to be clean until somebody complain it's not worth it and troublesome despite 20% pa return? Need to clean once a week? Once a month?

first time fine,
2nd time could be jail already.

good luck.

if smart meter, more gg.

every hourly usage pattern is all recorded inside the meter.
including, V, A, PF, Wh, Varh, VAh, angle and etc.
got hourly, daily and monthly profile. all recorded.
if the meter with modem, mean all data already uploaded to server database.

even burn the meter, as long as the memory chip is alive, still can extract the data out.


even u open the terminal cover, also recorded date and time.

You need 5 years to break even. Imo, it should not be considered as ROI during the first 5 years. Don't forget to add the opportunity cost of the RM47000 you coughed up.

After this, baru can consider ROI.
*
It is ROI.
But the ROI needs to minus off any maintainence fee /interest (if borrowing from bank) and asset depreciation.


TS doesn't include Asset depreciation so it's kind of flawed

Do you know the NEM only valid for 10 years? Your "return" has an expiry date. Year 1-5 trying to recover, then Year 6-10 you earn some. Year 11 onwards, you are on your own.
*
Partially true only. At year 11 you can only offset day usage but no longer night time, so your returns is roughly half.

5 years ROI, quite good if there is no additional charges and can run another 5 years.

How about repair and maintenance?
*
Biggest unknown is inverter. That's why need warranty + reputable brand for this.

Solar panel being passive will last very long.

Last time I check with many Solar sellers. All advice if bill only ~RM2xx...better do energy savings. That's why I didn't go for it...

Your bill RM800/month confirm worth it...

tell your bro don't play. He will get caught. So far i surveyed most friend/family who adjusted meter kena. You just need to ask when no one is around, they will confess.

Malaysia is like that. Before kantoi they tell 9 street what they did how they untung. After kantoi they keep quiet only cos face more important than anything else.

I just glad they changed to digital meter never kantoi me. This adjusted meter thing is a major hindrance that is preventing me from installing solar years ago. I could have gotten NEM2.0 if not because of it.

first, you need to take out 50k to install
second, you only started, what about maintenance? how long it can run without issue?
third, most ppl electric bill around 200~300, why take out 50k up front
the 50k can pay 13 years of RM300 electric bill.
*
If your electric bill is rm300, don't use solar.
You haven't reach the highest tarrif level yet.

Of course at rm150 you haven't reach the highest tariff level yet.
But why do you assume people are asking you to install?

because business stop using electricity at night
these high end residents, their electricity shines at night laugh.gif
they use equally more or less that those business at daylight

which makes their electricity bill way higher

Appreciate for sharing some of your bill details.

Seems like you might not be comparing it so accurately when u said rm800 went down to rm40+?

Based on your example, if you used rm839.50 per month before solar installation, and your generation is rm552.90, you still need to fork out roughly rm300 per month? Maybe even more today since there is a surcharge of Rm0.10 / KWh, if your consumption is more than rm780 per month since July 2023?

Edit: Oh, u modified your drillz edi. Aiya ts, u only consumed 1240KWh (rm600) recently..
