Solar panel is a device that directly or indirectly converts solar radiation energy into electrical energy through photoelectric effect or photochemical effect by absorbing sunlight. The main material of most solar panels is "silicon", but the cost of production is relatively high. It is so large that it has certain limitations in its universal use.
Compared with ordinary batteries and rechargeable batteries, solar batteries are more energy-saving and environmentally friendly green products.
The service life of solar panels is determined by the materials of the cells, tempered glass, EVA, TPT, etc. Generally, the service life of solar panels made by manufacturers who use better materials can reach 25 years, but with the impact of the environment, solar cells The material of the board will age with time. Under normal circumstances, the power will be attenuated by 30% after 20 years, and by 70% after 25 years.
Solar panels are generally installed on roofs, square tops, large balconies, etc. Therefore, thicker panels are required to be unaffected by wind and rain in summer. Each panel of the solar panel is independent. Before installation, prepare the screws of each panel. The screws are stainless steel, so don't worry about rust; first assemble the bracket, the bracket is three layers, and the top layer is placed on the host And solar controllers, etc., the lower two layers put batteries. You can learn the installation steps of solar panels by looking for videos on the Internet. If you are not assured, you can ask vip solar to install them.
