Tbh, instal solar is a good move. Regardless the roi

Money sure can get back long term.
Maintenance here and there along the way - biasa lah but not that frequent la.
Most importantly, go green, save earth, leave a better world to the next generation.

can I know which company solar ure using? after reading all 15 pages it seems worth to get solar as my bill is about 1k

not sure what is better for the environment, use less electricity or install tons of solar panels to accommodate ones outrages energy usage for residentials.

Sure. Later when I have time I pm u.

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.

You are not using energy efficient AC. Switch all to 5 star energy rated AC.

When you put returns like that it will be compared with other investment class. eg:- 5.5% epf , 3% FD, 6% ASNB but you cannot really compare them that way,
If you put 47k in FD, 3%  for 5 years you get 47k + (3%^5*47k).
The 47K that you put in is unchanged after 5 years

If you put in 47K in Solar and you claim 20% return.
By right at the end of 5 years you get 47K +(20%^5*47k) but you don't get it.
You can't sell the solar panels and your solar panels are not worth 47k anymore. . That is asset depreciation.

So technically, if you include asset depreciation. The first 5-6 years is 0% and then only after that is 20%.
You don't understand that you cannot get back the capital that you put in.

two ways to look at it.

if u keep the money in epf, u still need to pay tnb bill right? say u withdraw money every month to pay 800 to TNB, how much of this 47k will be left after 4 years, or how many years the 47k totally depleted by using it to pay tnb bill?

if u use the 47k to install solar pv, say 800 tnb bill saving per month, what u can do is to invest the 800 into something that can give u 5.5% return, i dont think thats difficult to find such investment (say just buy maybank shares lah that give annual dividend 6 to 7%), in 4 years, u will get about 44k in investment, in 8 years, your investment value will be about 97k, while if the money still in epf, that 47k will increase to about 73k in 8 years, the gap will grow larger and larger

1k bill is the sweetest spot for solar installation. U can escape the surcharge. and to reach 1k bill your house should be big enough to install more solar panel.
Calling rm800 outrage energy usage a bit unfair wei. My neighbor and family all average rm500-1000 electric bill. Especially after they change it to digital meter.

If ur bill not rm500 and it's a 6 person household i think your meter something wrong. lol
Yeah now i realize none of my AC inverter. Probably that's why.

installation of solar shouldnt be excuse to rake higher energy usage but it sometimes incentivized ppl reckless behavior like my neighbor could have walk to tempat beribadat but he drove his big ass SUV.
i think even i have the 47k for epf/other instrument for upfront, i'll still EPP it.
i think a lot of ppl see it as investment first and thinking they have 47k upfront to foot it (or maybe they have but i dont), like bee mention my system seems perform lower but from a longer stance perspective i still stand to benefit financially from it based on current situation.
so in my case i have a monthly 400 bill which i pay to cc instead of tnb, but in 5-7th year these 400 become extra which i could put in to epf

just saying, of course EPP even more beneficial as its 0% interest and the epf money still giving 5.5%

how many years EPP u r getting? what i heard max 4 years only

if 4 years EPP, your monthly installment will still be higher than your tnb bill and can only see net saving after 4 years

You can install less solar panel so the cost will be lesser. iianm it is 16k for around rm200 yield. lol why everyone keep stuck in the perpetual loop of " NOT EVERYONE HAVE RM800 BILL!!!". You can just lower your system to match your monthly bill. TNB will require u to do it anyway, they wont let u generate more than your current electric bill. No one is close minded here. chill.
Again u don't understand ppl who installed solar already know they not going to shift new house in the next 10-20 years. It generate income as long as there is a sun and someone living inside the house.

It's less capital and much less hassle than owning a property that generate rm800 rental. No tax even. The only downside? I lose it all in housefire or tornado. But still at that point losing 47k should be the least of my worry. lol

Maybe can save a bit. But I don’t think will be very big different. 

Also the cost of changing the energy efficient ac is quite high also.

Btw, he just escaped the 1500kwh surcharge after installing the solar

If he wasn’t on solar, his bill would be 1k for September. Due to the surcharge. Now he only pay rm80. .  His roi is way faster now. .

It's about the accuracy of the ROI term.

If someone tells you FD ROI 15%
or Solar ROI 20%.
Which is a better investment?
From numbers alone Solar is a bigger number therefore it has better ROI right?
But that is not true. Why does FD ROI of 15% outperform Solar ROI of 20%?

Okay. What if this is the scenario.

Scenario a
Put 47k in fixed d

Earn interest

Everry month another fresh 800 pay to Tnb.

For 10 years

Scenario b

Put 47k in solar
Every month another fresh 800  put into fix d.

For 10 years.

Which one is more worthwhile. ?

Okay.  To answer my own question.

Scenario a
By the end of year 10, will have rm81360.59

Based on interest 5.5 percent.

Scenario b

End of 10 years.
Will have  RM 126,806.07

Based on 5.5 interest

And a 47k system Solar that still generate but depreciated in value or no value.
Did I calculate any wrong here?
