Distributed grid-connected photovoltaic (pv) solar panel bulge the cause and the

Solar panels on the location of the hot spots and invisible tape location are prone to the back bulge, and when the two overlap more prone to the back bulge, mainly because the panel temperature caused by too much angry words. The sun in the solar panels in the use of the

solar panels on the hot spot and the location of the invisible tape is easy to make the back bulge if two overlap, backplane uplift the possibility of larger, mainly because of the temperature of the panels are too high. When used solar panels, solar panels absorb part of the sun itself will be converted into heat energy, caused the temperature of panels internal components to soar. Uv absorber of EVA will absorb ultraviolet light is converted into heat energy, and spread the inside parts. In general, the normal work of the solar energy battery components temperature about 70 ℃ 80℃。 Many experiments prove that hotan employees on new energy, the rise of temperature will affect the power output of solar panels. Rising the temperature of the module itself every 1 ℃, module about 1 W output power will be reduced. Therefore, should be considered in the process of back material choice back material coefficient of thermal conductivity. Coefficient of thermal conductivity and the materials and components on the basis of the backboard itself. Heat is mainly composed of transmission medium. In this case, the hotan new energy will explain the solution: solar panels bulge when cell in operation, to ensure that the input cell and qualified for the standard battery. In the process of welding, such as welding, virtual welding. Should be avoided and should be laid paste invisible tape according to the drawing.
