International conventional crystalline silicon cells have an efficiency of 10% to 23%. Solar panels made up of one or more solar cells are called photovoltaic modules. At present, photovoltaic power generation products are mainly used in three major areas: First, to provide power for non-electricity applications, mainly to provide electricity for residents living in areas without electricity, as well as microwave relay power and communication power supplies. In addition, there are also some mobile phones. Power supply and backup power supply; second, solar daily-use electronic products, such as various types of solar chargers, solar street lights, and solar lawn lights; and third, grid-connected power generation, which has been widely implemented in developed countries.
The solar mounting structures have be developed to use all kind of solar panel mounts in any areas of the world.
