I see. Interesting fact.

So we need to weight the solar panel installation, what do we want in the end.
Still, why we need to have quota for this? In Malaysia, we are blessed with sunlight > 180 days. Even in the rainy days, we are still getting some sunlight.
Like European countries, they are ditching fired power generation and encouraging people to use green power to generate power.

So little? That is slightly more than half a year only wor.

Is just an estimated figure only.

I see. Okok
But I think can easily get over 300 days a year la

We got sunlight also cloudy too.

365/6 days have sunlight, but what I mean is the quality of "hot" sunlight.
And the panel direction also comes into play.

you means 52 x 6 days a week.
Yaya, rain, mist and humidity all affect the out come.

That's why don't think it can give you 100%
If you think like this, you will be sad when you see the return

I almost venture into this. Luckily i didn't

As said, you need to consider all the factors.
Just say, without this solar panels, you are spending rm200 for your electric bill monthly. But once you install this, you may only paying rm150, for long term it is something.
But for just investment sake, I think it is not that good.

I already have solar heater panel at roof top.
I know the effect is too little compare to the whole roof with panels la. hehe

The installation wrong, maybe?

The heater work perfectly.
I mean the cooling effect is not there.

Sheet
I see the wrong one. Solar panel heater won't absorb much like those solar panels.
Yours only cover 10-20% while the other type can cover 50%

Yaya. Probably less then 10%.
Btw, i saw some house almost the whole roof is covered by the solar panel. It looks kind of weird.

Try to pay them a visit inside and see how
