weikee...he said its 9K installed.

ozak....true on the quality. Panasonic quoted almost 11k a kW. so maybe there's disparity on the quality and output.

sigh. don't know which is a good provider to get more info from. Was hoping those that have installed will be able to provide some feedback. cheers.

All income generate from FiT are taxable. Please factor in this Roi

Is income from feed-in tariffs considered taxable income?


Yes, it is taxable income and any exemptions would require a policy decision from the Government.

It is well worth to research in the modules that you are selecting. Having said that there are only 2 locally manufactured Si modules that i see trusted. One being q-cells, the other is MSR. I do not know if Panasonic started to sell locally (Plant in Kulim). Maybe others could share other supplier that could obtain the RM0.03 cent adder.

The other factor I believe good customer support for warranty claim. As it is standard module will have the performance warranty:25yrs. 90% - 1st 10yrs, 80% - next 15 yrs. So at least supplier can swap any defect modules/complain fast.

Actually the main killer in Si modules are the heat from the roof. Commercial projects i.e warehouses, system are design with a lot of clearance from the actual roof. Most will degrade at a rate of -0.4% per degree raised.

April 2013 average generation is 3.48kWh/kWp but July looks like going to be lowest, up to now is 3.33kWh/kWp

Oct, and Nov could be lower.

If I am not mistaken, the panel from Sunpower also considered as locally manufactured. Sunpower panel has the highest efficiency and lower degradation rate but is more expensive. Anyone investigate this panel?

This year sharp came out the highest efficient panel which I think will take few more years to go into production.

It will definitely takes a number of years to be available commercially. Just curious, what are the comment solar panels available in Malaysia market?

It look like just want to achieve something rather sell this panel to you.

If you want high efficiency panel that really selling in the market, look for panasonic. That high efficiency panel is actually takeover from Sanyo.

There is a provider quote rm16k/kw. All the parts include panel is from Germany. High efficiency and even have insurance include for you. The insurance is not from the provider. But the German panel manufacturing.

I hear that Panasonic HIT series (locally available) is one of the best....

I was looking at Bosch panel, but lost some confidence when they put the whole business up for sale recently.

Personally, I have come across generation performance for QCell(mono), Panasonic(mono), Yingli(poly), BYD(poly) and CNPV(poly)
All have similar capacity (240-245W) and ordinary panel (not HIT, n-type mono)
Guess what? All have same performance. The difference is minimum.

Have you investigate Sunpower panel. From my understanding, Sunpower has one of the highest power rating. For example the E21 series can produce 327w.

The e-series that you mentioned is 96 cells configuration so you must then compare the same size/configuration.

I have attached a simple summary. In general a lot of manufacturer have 6x10 cells as standard. For this case I could not find for Sunpower and Panasonic.

In short conclusion between Sunpower,Q-Cells,Panasonic:
1. Highest output module: Sunpower at 327Wp.
2. Highest output per cell: Q-Cells at 4.5W/cell.
3. Lowest heat coefficient: Panasonic at -0.3%/deg C.

You must know the cost RM/Wp as this is how modules are sold. In the end it depends the whole system cost and your assume ROI.

My experience above is based on actual performance in Malaysia. No investigation involved, just compare generation data.

I have not come across any Sunpower panel yet. (I'm in doubt. Any guys want to bring in Sunpower?) Sunpower is expensive brand. E20 series is high efficiency panel. Each solar panel company has high efficiency panel for showcase and Malaysian SP don't use them. The pricing is not justify when compare to ordinary panel. I haven't meet any Panasonic HIT or Yingli Panda in Malaysia.

In case, you want to investigate, I suggest you to look for "Temperature Coefficient of Pmax". The lower the better. This is the measure of performance drop when panel working at temperature higher than 25deg C.

From dude35's table, panasonic panel has the lower 'Temperature Coefficient of Pmax' and it is smaller in size. For those who has small roof, panasonic panel may be good to maximize the total output per area.

Does anyone know how much more expensive are the panasonic or sunpower panel cost compare to other panel?
Personally I have not seem panasonic HIT panel yet but have seem the normal panasonic panel whit is not the HIT model.

Eventhough sunpower has more cells but the panel size is relatively about the same size (1.6 x 1m) compare to the general panel. So I guess it will be good for those want more power from limited roof space. Just do not know how much extra cost will it be.

It seemed there is a lot of taker for solar right now. Around 790kW was taken up in 24 hrs.

As usual, people always wait until last minute before hurry hurry up to get the quota.
