hi guys...

time to start looking at this, since tnb tariff is only gonna get higher and higher..

anybody have any experience in this ? in respect to using solar to

1. power lights (night light/security lights)

2. power fridge/ventilation fans/water pump

3. sell back extra to TNB or who ever that supplies the electricity

Tnb tariff already up? Again?

Last month got survey form to fill up from some university guy past to us in my taman. Regarding poor respond about solar power generation and why. After read the form, seems like many red tape, cost and less advertise cause poor respond.

not yet.. dont think it will be cheaper... but i think solar technology will get cheaper as time goes on...

if you install a solar energy system you ROI in about 10 to 15 years..

if the tariff goes up then you ROI faster..

The solar technology is not cheap in here. People are taking advantage now to gain more profit with solar product here. Even it is cheap.

At the moment in here RM11/watt for solar panel while I check outside example in Aus is RM8/watt.

But tnb not going to payback at what the price given now for on grid once getting more ppl instal. I learn this from aus gov now. t is just given you sweet now, tarik back later. So you got to calculate carefull the cost to invest.

One thing I still not understand with on grid supply back to tnb. If I do that, I need to invest more on solar beside my own consumption. Wouldn't that cost more?

i wonder if a gen set is cost effective way to power your aircons and water heater compared to solar?

this is more about, if you generate more than you use.. you can sell the surplus back to the utility company... but i doubt that...

doubt that.. cause there is conversion loss already which make it not as efficient as it should be

gas > gen > power

Beside the noise, the fuel is killing you.

And don't forget the carbon dioxide is really killing you.

And if you have extra to generate back, do the consumption is enough for you to take back ROI? If my daily comsumption is 1kw, how much kw solar do I need to buy for solar with extra to generate back to tnb?

Still many thing in doubt and really benifit us.

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.

im not sure about that, that is why this is here for discussion

80k wow thats alot unless you have tons of roof area and high quality panels, dont think u can make much profit from selling to tnb...

now my bill is about 200 bux and i use a solar power to power my fridge/lights/aircond(at night), i can cut 200 bux and put that up into the cost

then at least electric bill is lower (min), thus from that way longer and longer term, you dont get affected by the rising tnb tariff..

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

Have you done the calculaton and their detail explanation about this on grid?

Added on September 26, 2011, 10:42 amThat is off grid solar generate. I m thniking of this too. But not the whole house consumption as the investment is high. Maybe just start with some light.

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

wind turbine is noisy and to generate sufficient needs to be damn big..= ugly..

solar panel just sit on the roof, provides a second layer of thermal protection to the roof

@osak , yeah maybe start with lights first would be better, install 120w panel with 2x 100AH batts power

maybe 2 or 3 18 watt Philips lights, cost would be around 3 to 5k i think for a simple project...

would be better is can totally power fridge + aircond from solar that would be the most cost effective as those two items takes up a bunch of power from tnb bills..

Err ... I thought that if we install solar power panels on our roof it will generate sufficient power to supply all our household power demand day and night,
furthermore can get extra cash back when we sell extra power generated to TNB .

Forever free of TNB bills and in reverse get money every month from TNB .

Wishful thinking I guess

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.

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...

A 5k solar kit can get a 180watt set. That can generate 2.4kw/perday with battery. You can power up 12ps 23watt energy saving light for 8hr. Not bad to start with small first.

To power that fridge+aircon is already full whole solar system liau.

If you have a chance to oversea, grab some solar panel kit. Much cheaper. But prepare to pay 30% tax when go through custom.

Added on September 26, 2011, 1:12 pmThe last I get quote from some solar expert here is RM60k. He said that is enough for you whole housewhole. That is enough to put me off too. He....

Recently visit AUS and my friend bought me to some of his neighbour to see thier solar set on grid. Quite a lot there. Is cost $16k there.

AUD 16k is about right loh RM 60k

I find now Malaysia price no longer cheap. Other than labor what else is cheap?

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.
