Photovoltaic Lightweight Module and Tradition

Photovoltaic Class A modules: mainly used in ground power stations, distributed power stations, household systems, etc. , the service life is over 25 years.

. The price is mainly around 3.5-4 yuan.

Photovoltaic module B: mainly used for street lamps, off-grid systems, battery cars, etc. , service life of 5 years.

. This kind of components are made of Class A degraded components or Class B materials, and the price is around 3 yuan.

Class C photovoltaic modules: mainly used in underdeveloped areas, such as remote areas, Afghanistan, the Middle East and South Africa. , the service life is unknown, and the price is around 2.5 yuan.

These phenomena will not appear in class A batteries.

Poor appearance: color spots, color difference, aluminum thorns, bulging, broken grids, nodes, graphic deviation, missing corners, broken edges, gaps, etc. ; Poor external packaging of components: back plate failure, battery plate virtual welding, over welding, poor sealing, back plate scratch, frame scratch, glass scratch; Poor packaging of junction box, etc.

How to produce B and C components?

First, in the production process, the components whose appearance and electrical performance are not up to Grade A are reduced to Grade B or C..

Second, the appearance of Class B and Class C components directly produced is basically the same. There is no simple and intuitive way to distinguish between good and bad components.
