Q:Why and what is the low efficiency solar cell?
Sometimes the solar cells made of bad quality silicon can cause the result that the solar cells you are using is lower efficient than when you started to use it. You might need to change some materials.
Q:How do people price solar cells? Is it based on a specific way of calculating the cost of solar cells?
The pricing of solar cells is based on it's material used to made it, the cost of building it and maintaining it. In fact, it doesn't cost much ever after every installation of solar cells system is done.
Q:Can I trust the suppliers for film solar that I found on alibaba.com?
Well, it really depends on what kind of suppliers you are dealing with, because as a matter of fact, some of the suppliers on alibaba.com are very tricky!
Q:Is that true that the price of solar cells will be reduced in the coming year?
TrendForce, a professional survey firm based in Taiwan announced March 10th : because the global market demand for solar cells is declining it is very possible that the price of solar will eventually goes down.
Q:What is sun cells technology?
Sun cells use high technology to change the sun's light energy into electrical energy. The sun cells can be used in the industries such as satellites, navigation lights, transistor radios and other power supply services.
Q:Is A grade better than the B grade when we buy the poly solar cells.
We did a test based on 10 poly solar cells we bought in the market, and it turns our 5 of the poly solar cells claimed to be A grade product is just the same as the B grade.
Q:Do you believe you can make a solar cell by using kitchenware?
No, I don't believe it at all.
Q:Where and how can we find the best solar cells suppliers?
I usually use to find the solar cell suppliers here: 1 alibaba.com, 2, made-in-china.com 3. globalsources.com
Q:Where can I buy solar cells?
Actually you can rent one, no need to buy one.
Q:Can anybody tell me the power supply of the home solar cell?
In my old place, all I was using was the 50WAT solar cells, which is definitely good and useful for all my daily use.
