A normal house Solar with push back to the Grid (contra) system is about 80k+-. I ask this last year. Earlier there was a subsidy from got and house owner pay about 1/2 of the cost, but is already end.

You need to change the TNB meter two two way. And all installation are approved by TNB and Gov.

You can go to TNB and ask, they have one small department doing this, but now think they focus on commercial.

It don't look like encouraging and supporting from gov. Whitout much public know and realise, the prog already end. sad.gif

Have you done the calculaton and their detail explanation about this on grid?
It was publish in the news paper, i read about it few years ago.

I don't want to calculate the ROI after hearing the numbers. I was expecting like 10k +-, but after the consultant told me is about 40k after gov subsidy I lost my interest. Hope the price have come down substantial.

Maybe we can install wind turbine instead biggrin.gif

RM10k solar set probally can generate 360watt.

I have read some wind turbne. Unless your area have wind above 25mph (something like that), if not don't think about it. Can't drive the fan move at all. But you can add wind turbine as supplement to your solar setup if it not that expensive. smile.gif

We need average about 1Kwatt hour per day (average out), peak minimal about 6Kwatt - 8Kwatt for a terrace house. So that maybe need about RM 40k to just cover one household need. ROI will be very long...

Maybe the gov there given good subsidy. But my friend told me, the gov start cutting back since now many go into it.

Solar not cheap here cause seller take advantage of the less ppl adventure into this field. Even some simple china solar product here cost double.

Do you know many things need AP to bring in? I need an AP to bring in a faulty router from my oversea office. What a joke. And all this add up the cost.

So everyone, you know why things so expensive in Malaysia?....

Are you kidding me. A faulty router need an AP?  What the router categories at?

My company do a lot of buying and selling parts and machine to oversea. And never need any AP at all. Just once a while get tax for some parts.

6K initial pay up is good. But 4KW generate and sell back say 3KW after minus household usage. Base on my calculation it take long ROI.

Say:
- sell back 0.60 cents per hours for 3KWh (assume sell back is 0.20 / KWh)
- one day say peak power generate is only 5 hours (10am - 3pm)
- One month 30 days
- 0.6 * 5 * 30 = RM 90.00

RM 54,000 / 90 = 600 Months (50 years). That provide the photovoltaic running for 50 years without maintenance.

FiT works different weikee what you describe is net-metering. You sell ALL your power to TNB for a given price (around 1,50 under proposal i think) and you buy ALL your power from TNB at the REGULAR rate. This makes it pretty efficient if you have a large perfectly situated roof to work with. In fact your ROI can be around 8% ++ p.a.

sadly my roof is endangered by upcoming house-renovations. Any shading can totally f*** up your calculation so you need to be totally sure no neighbour can ever or will ever cause any shade to your roof. If got shade on the roof then the whole thing not worth it financially already.

Wait till we get official charge back rate than we will know actual ROI. They always paint the picture so nice.

I saw someone selling Solar PV Solution for Residental
From my breif discussion this is the summary for this system
Basic Package
Cost RM36 - 40K
Generate approx 300kwh / month - Sell to TNB @ RM1.49/kwh - TNB pay us RM447.00/month
We use 1000kwh / month - cost average @ RM0.30/kwh - We pay TNB RM300.00/month
Therefore per month we untung 147.00

Please ask for guarantee from them smile.gif I bet they don't dare.

Take example of Diesel, it take them forever to implement Euro 4 diesel, E4 is much more friendly and better, this allow more diesel car come in. More economical and fuel efficient. Now delay another 2 years. Maybe 20 years until our lung get black.

It is not the space but the budget. Average terrace house roof can be over 4kw. The cost pv here have been drop. In 2010, the price drop to rm19k here.

With the high cost investment, I doubt everyone will have a environment conscious. A 4kw system can cost you rm60k. I even can't effort it. Not to say go green. Unless gov come out some special loan, subsidy etc.

Can get us some answer regarding the initial cost, how we can effort, what rate and ada contract or not. smile.gif

You need to consider supporting the roof, and other factor too. Additional money. Average terrace may not fit in 4KW, it need to have proper wide space. If like my house stupid sime design with odd shape roof it will have poor coverage of sun ray.
