Q:I studied very hard at school, but I just can not figure out how solar cells work, anybody can help me with that?
The process of solar cells' conversion first requires a material which absorbs the solar energy (photon), and then raises an electron to a higher energy state, and then the flow of this high-energy electron to an external circuit. Silicon is one such material that uses such process.
Q:I bought a new poly solar cells, and the test result of the conversion efficiency is 16.8%, is it lower than usual?
I don't think it's lower than normal, 16.8% is pretty common in most of the power plants in my area.
Q:Why are the poly Solar cell specifications is different from each other, they seem to have the different size of 125mm, 156mm, 152mm, is the 152mm's battery technology is higher than the other?
We seldom see poly solar cell with the size of 152, because that is not really good to use.
Q:How can I buy the solar cells wholesale ?
The wholesale price for solar cell is based on your quantities of the solar cells you want to buy from the manufacturers. The more you order, the cheaper wholesale price you would get.
Q:How does solar cell technology apply to our daily life?
Solar cells are used to make solar modules which generate electrical power from sunlight,
Q:I am a purchasing manager for a EPC engineering company, and we are planning to purchasing some 4bb solar cells for one of our project in Taiwan, can I get a quotation online?
Welcome to visit our company website for more information about the wholesale 3bb and 4bb polycrystalline and monocrystalline pv silicon solar cell price made in Taiwan and china mainland.
Q:Is silicon-based solar cells and silicon-based thin-film solar cells the same?
General silicon-based solar cells refer to monocrystalline silicon and polycrystalline silicon solar cells, while silicon-based thin-film solar cells are similar to sunpower producing that type of battery that can be made into curved components.
Q:How much does a solar cell cost?
Figuring out exactly the cost of the solar system you have can take a little detective work.
Q:How to get high voltage, high current output of solar cells
Using 880 0.5 volt 5 amp output of the panel, 440 in series as the first group, and then get a second group, then the two groups in parallel, you can get 220 volts 10 amps output
Q:How about the solar cell 156mm Mono-Crystalline?
It is the kind of solar cells That is unobstructed sunlight of the outdoor environment and it can be Operated under the temperature between -20 ℃ to +85 ℃
