[A:] The solar panel cells, components, frame, tempered glass, packaging materials and junction box, you can use the sun to generate electricity in a board.
[Q:] What types of solar panels, and what’s difference?
[A:] monocrystalline, polycrystalline, amorphous three kinds of materials. Among them, monocrystalline is with higher best efficiency, and prices are high; polycrystalline low efficiency of 2%, almost the price of these two life more than 25 years; amorphous low efficiency, short life, but the price is cheap.
[Q:] What’s the standard test conditions of the solar panels?
[A:] the power of solar panels in standard conditions: temperature 25 degrees, AM1.5, the 1000W/M2 test. General use WP (peak watts) that can also use W (watts). Power in the standard test known as the nominal power.
[Q:] how does the solar panel work?
A: The solar panels in the light of a certain intensity can produce current, connected appliances can be used. The premise that the current generated by the unit of time is greater than the electrical consumption. In practical applications, this direct use is relatively small. Are generally used by the entire system.
[Q:] Can I have the sample of solar panel?
[A:] Suer, you can order the sample for testing the quality of solar panel, but the price of sample is different from the large quantity.
