Shenzhen disheng energy technology co., LTD. Focuses on solar energy for 10 years.

Multicomponent solar panel photovoltaic modules.

Multicomponent solar panel photovoltaic modules are solar cells made from a single element of semiconductor material. Countries to study the variety of now, most have not been industrialized production, mainly has the following kinds: a) cadmium sulphide gallium arsenide solar battery solar cell b) c) copper indium selenium solar cells (new band gap gradient Cu (In, Ga) Se2 thin film solar cells)

The selection of solar cell film has three grades A, B and C, and natural A is better. However, the advantages and disadvantages of solar panel photovoltaic modules cannot be fully determined. The processing technology and material selection of components determine the overall performance and life of solar panel components. Choose carefully, see if there is golden sun, TUV, CE certification, the quality of certification is guaranteed. Normal can also be observed by the surface:

1. Carefully check the surface of toughened glass. In order to improve the production speed, small manufacturers often don't care about the silica gel on the surface of toughened glass. If you do not remove it, it will reduce the power generation efficiency of the panels.

2. Watch the battery

A lot of informal manufacturers with broken cell, what seems to be a complete cell composed of welding, this way there is a big risk, early may not be very obvious, but late patchwork cell easily broken again, affect the use of the whole panels.

3. Look back

Look at the quality of the back pressure, and there are no uneven conditions, such as bubbles and wrinkles.

4. Look at the border

Due to the solar panel industry low barriers to entry, many small manufacturer with the method of artificial playing box, artificial dozen box, because of the unequal every time frame's strength, play good box contact close degree also differ, modelling is not a strict rectangular, solid degree also sell at a discount greatly.

5. Look at silica gel

See if the silicone gel is evenly distributed around the back, and whether it is close to the gap between the back plate and the border.

6. Watch welding

Carefully observe the string welding of the battery. It also depends on whether the battery is arranged neatly.

Look at the junction box.

Finally, if the junction box is firm, the lid of the junction box can be firmly attached to the junction box. See if the wires are rotating freely and can be tightened.

To sum up, the quality of solar panels is more important, and the quality is judged from the subtle points.
