China Paint Online News Information: How
identify the advantages and disadvantages of PC (polycarbonate) solar panels? According to
China Coatings Onlineexperts
Shao, PC solar panel for polycarbonate as the main raw material production and manufacturing, is currently a wide range of international polycarbonate plate to take a high-intensity, light transmission, sound insulation, energy-saving new high-quality decorative materials. In recent years, some domestic manufacturers in order to adapt to the needs of demolition customers, the production of a large number of recycled materials of poor quality solar panels flooded the market, because of the dealer's misleading, so that customers on the sunboard's true and false good or bad can not be distinguished. Sunshine board resolution skills are probably a few, the actual purchase also have to be flexible use, it is recommended to buy a new ten-year warranty products, only the new PC material products can be guaranteed.
The basic method of distinguishing the quality of the sun board, first look at the transparency, the best sun board light transmission in about 94%, the lower the price of the transparent sun board rain shed its recycled material added, the worse the color of the sun board. Also have to pull open the protective film to see the plate. Impurities-free sheets are new raw materials, on the contrary, there are impurities foreign materials are added to the recycled material, the more impurities added to the more impurities the more obvious the board quality is worse. Look at the thickness of the upper and lower walls, the thicker the material, the more sufficient the material, the higher the proportion of polycarbonate material, the higher the cost, the better the quality of the plate, this method is also the same as the weight of the sun plate called the unit area.
Also pay attention to bending the sun plate sample block, fragile plate quality is worse, PC (polycarbonate) plate is better toughness, if the plate is very easy to break, it is not pure PC material, that is, added recycled material of the sun board. Look at the surface of the sun plate PE protective film if the paste is better without shedding phenomenon, indicating that the equipment process is not backward or manufacturers more rigorous production attitude. Look at the flatness of the plate, flat plate on the one hand shows that the upper and lower walls are thicker, with sufficient material, not easy to deform, on the other hand, the equipment process is also better, if the plate has waves appear, that means that the sun plate process is not mature or the upper and lower walls are relatively thin. The same specifications of the sun board, different brands of solar board price gap is too large, that low price of the kind of sun board must have a problem.
