How can the naked eye distinguish the quality of PC sunshine board?
The light transmittance of solar panels with long warranty period is about 94%. The lower the transparency, the more recycled materials will be added, and the color of defective solar panels will be black. Open the protective film and look at the plate. The plate without impurities and particles is a brand-new material. On the contrary, the boards with impurities and foreign bodies are added with recycled materials. The more recycled materials are added, the more obvious the impurities are, and the worse the quality of the plate is.
2. Look at the thickness of the upper and lower walls
The thicker the thickness, the more materials, the higher the proportion, the higher the cost and the better the quality of the plate. This method is also the same as weighing the weight per unit area of solar panels. The worse the quality of the brittle board is, the better the PC polycarbonate board is. If the board cracks easily, it means that it is not pure PC material, or it is a sun board with recycled materials.
3. Look at the flatness of the plate
On the one hand, the flat plate defines the thickness of the upper and lower walls, and has sufficient materials and is not easy to deform; On the other hand, the equipment and technology are better. If there are waves in the board, it is obvious that the technology of this sun board is not sophisticated, and the upper and lower walls may be relatively thin.
Look at the price
The price of the same standard sunshine board is different for different brands, so there must be something wrong with the low-priced sunshine board.
