My bro house paid 3K for ppl go fix the meter every month bill just RM300.
Can ON aircond whole day

Saving = RM 750

RM 750 x 12 months x 10 years = RM 90,000 (consider your panel doesn't degrade at all, no maintenance needed at all)

RM 90,000 / RM 47,000 = 191% for 10 years.

Let's calculate the CAGR

1.91^(1/10) = 1.067

Meaning 6.7% Compounded Annual Growth Rate (Again, with no solar panel losses, no maintenance needed, no solar seasonal pattern). That's the absolute max you can get for 10 years.

After 10th year, you needed battery to make it viable.

my tnb bill average 40 ringgit only

if i install this, would it generate money instead?

You can renew, buy new set of panel, new installation again.

I just calculate what went in and what came out. Simple.

RM 1000 paid as bill = RM 1000 paid as investment, it's the same RM 1000 after all.

4 months battery still tip top
3 years later maybe efficientcy drop a lot.

Do you have any viable battery option now?
10kvah can easily be 30,000 currently.

I agreed. However your return will not suddenly increase from 6.7% -> 30% due to different payment schedule.

TS tokok singsong only. Show la tnb bill before and after install solar

I got ask you meh? Your mom don't teach you if no people ask just sit down and shush?

Yes it will generate for 20-30 years and you can only use it during day time.

Night time is what kill your TNB bill, not day time.

I average 35 kwh per day of usage and day time we hardly hit 10 kwh, at night that's another 20-25kwh of usage, mainly from air conditioning.

So without battery, your panel will be covering just max 1/3 of your usage. Not entirely.

I am an avid solar supporter, but it should be backed by solid facts and figures.

ROI extremely fast based on TS high monthly usage

26 panels = 26 ways to fail, also extremely fast.

You think we all live in an area without dust? haze?

Talk so much but not a single proof

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.

TESLA powerwall seems to be ok.
Around 25k for 10 kvah. Not too bad actually.

They are interested to see the TNB bill itself.

How much is your import as of now?

It will take 50 months to recoup that RM30k, excluding opportunity cost of RM30k.

Then there's degradation of performance to think about, which stretches the break even time. And the inconvenience of having batteries at home (space, risk).

Yeah why not
