if your staying in a large single/double story housing area with no high raise anywhere other than trees..

it could be very worth while.... to look into long term..

as the electricity tariff will sure to go up as time passes by... maybe first 5 years its about 4% when the tariff is revised might jump to 8 or so

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.

There is a new type of panel which more suitable for climate here. It call thin film or a-si or Amorphous panel. It tolerate shading and hot temperature. But you need bigger roof. It less efficiency compare same size as monocrystalline. Check it out.

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

Wonder how true is this. The BIPV tariff already passed and will start in december?

QUOTE
Malaysia: PV Interest at an "All Time High"  

KUALA LUMPUR, SEPT 29 (www.pv-magazine.com) -- As the Renewable Energy World conference and trade show winds up in the Malaysian Capital, Kuala Lumpur today, photovoltaic industry participants have reported never-before-seen interest in solar. At conference presentations on the third-and-final day, one conference stream was entirely devoted to solar technology, markets and innovations. The sessions were declared a "full house" by organizers and demonstrated the growing awareness of, and interest in, solar.

The organizers claim 7,000 delegates and 6,500 visitors attended the show. Image: Solarpraxis/Jonathan Gifford.

Shamsudin Khalid, the president of the Malaysian Photovoltaic Industry Association told pv magazine that interest in photovoltaics is at an "all time high of in Malaysia right now."

The organizers claim that 7,000 delegates and 6,500 visitors attended the show, which was held simultaneously with the Power Gen Asia conference and convention. As such, photovoltaic manufacturers like Trina Solar, LDK Solar and Sharp found themselves displaying their panels amongst fossil fuel and nuclear power generators.

FITs on their way

Amongst this diverse group, photovoltaic stalls attracted considerable attention. Part of this interest stems from the fact that renewable energy legislation has been passed by Malaysia’s parliament, which should see feed-in tariffs (FITs) introduced in December.

There is some uncertainty as to whether the FIT will be introduced on schedule, as it has already been delayed once. "We certainly hope it will meet this timeframe, of December. The industry is certainly waiting for it," said Khalid.

He does remain hopeful that even if there are delays, photovoltaics is on track to play a prominent role in the country’s renewable energy future. "Even if it spills over to the first quarter of next year, we are ok. Beyond six of 12 months it will be difficult for the industry to manage."

Grid parity approaching

During one of the conference presentations, a slightly different picture was painted. Roger Goh, an executive director at wafer manufacturer GCL, said that due to rapidly falling module prices, grid parity in places with good irradiation such as Malaysia, is imminent.

While describing the module and silicon wafer oversupply as being, "very, very bad" for manufacturers, he showed figures indicating that retail grid parity in many places in Asia would occur within three to five years. "Even in the east PV will be economically viable," he declared.
Here is the official tariff rate for BIPV. Does this rate good enough?

Some calculation which for you guy to analysis.

QUOTE
Easy calculations for system size and cost:
If you know your average kwh/day or know how many kwh/day you would like to produce, a simple calculation will determine system size and cost.

System size in kilowatts (kw) = (kwh/day) / 4 hours (peak sun) x 1.43 (system losses)
Step 1: Divide average kwh/day by number of hours of peak sun, or (kwh/ay) / 4
Step 2: Multiply by 1.43 to account for system losses due to friction, heat, and other inefficiencies.

Example: What size system is needed to produce 20kwh/day?

20kwh/4h = 5kw
5kw x 1.43= 7.15kw
7.15kw = system size to produce 20kwh/day assuming 4 peak sun hours (11am to 3pm).

System cost = system size x RM13,000 to RM15,000
Step 1: multiply system size by RM13,000 for competitive system cost installed
Step 2: multiply system size by RM15,000 for conservative system cost installed

Example: How much would a 7.15kw system cost?
7.15kw x RM13,000 = RM92,950 = competitive system cost
7.15kw x RM15,000 = RM107,250 = conservative system cost

We used to see an average cost of a grid-tied system to be about RM15,000 per kilowatt (array size) installed, but with a growing market, systems are being installed for as low as RM12,000 per kilowatt in competitive areas.  Keep in mind that these costs are before any incentives or rebates are taken into account.  When the FIT kick in, the return of investment (ROI) will be around 9 to 14 years depend on locations, solar systems, technologies and so forth.

Hopefully this helped introduce you to some of the basic considerations needed before purchasing a solar electric system.  There is far too much information to cover in a short guide and anyone serious about greener living should contact us at contact@solarpower-mart.com or SEDA for more detail.

Please take notes:
1) Malaysia only has 4 hours solar insolation (some areas may be less due to pollution).
2) Malaysia has average of 2 months cloudy/raining day per year, which solar power is not favourable.
3) When solar cell (module/panel) heat up (after noon time), the solar cell's efficiency (power output) will start to drop.  Which mean during a hot day, solar panel (PV) actually produce less.  This is a major challenge for solar power in Malaysia.
4) Every few months, installed solar panels (array) need to be clean (due to dusk accumulation on the panel) for maximum efficiency.  This is an extra cost for the owner and may increased longer payback period. Please also find out other maintenance costs.

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

For this FiT tariff, better adopt wait and see. Don't rush for it.

Cause the investment cost is high. And gov like to flip flop policy. They can change anytime when favoure too much to you.

Or give you some sweet first. Later Tarik balik many thing. You can't do anything as you already invest on it.

Where got RM 30, is only RM 0.218 to about RM 0.4+ depend on usage.

In that case i'll sell the electricity back to them ... RM0.30 to gain RM1.49kw/h profit..LOL

Truth is Solar power has not reach the stage where it priced competitively without any rebates by the govt.

Tempered glass no problem. Laminated glass maybe unless is very thick.

Good point. Must use tempered glass next time if I put up a timber pergola in case got hail....... which happens now and then. (Sorry, off topic).

Those hailstorm not big enough to smach the panel glass.

All the solar panel standard come with tempered glass.

initially i thought there could be mistake in the statement but having checked on SEDA website (www.seda.gov.my) the FiT is somewhere about the figure given (RM 1.23 per kwh to be exact for the base calculation). if that is the case, it is encouraging people to go ahead with the BIPV implementation. having said that, there are many criteria to fulfil in order to entitle to this FiT. i will personally check with SEDA on the requirement and will definitely embark on this system if the ROI is good enough smile.gif well, save the planet!

I really want to get more details on solar panel supplier

the one at homedec exb was only for water heater and the http://seda.gov.my/ website is kinda pain to understand :S
