1. In terms of types, 405w 410w solar modules are divided into single crystal and polycrystalline.

Monocrystalline silicon 405w 410w solar module has higher efficiency and less light attenuation, but it is expensive. Polycrystalline silicon 405w 410w solar module has relatively low efficiency, but its price is low.

2. The external dimensions of 405w and 410w solar modules have many external dimensions and specifications. You must decide which size is more suitable according to your own street lamp installation environment. Generally speaking, under the same power situation, it is more appropriate to choose a smaller size.

3. The power generation capacity of 405w 410w solar module is closely related to light intensity, ambient temperature, installation angle, etc. Changes in each link will affect its power generation effect.

4. Raw materials, battery components generally include battery sheets, eva, backplane, aluminum alloy frame, and tempered glass. Tin-copper bending and tightening phenomenon; and bubbles will be generated, which proves that there will still be residual gaps during the 160-degree high-temperature heating and sealing process. The battery sheet attaches great importance to sealing and anti-oxidation, otherwise it will be 1-2 years in the open air The service life of the frame, including the filling of the frame gap, is a very important part of the process.
