[0002] Photovoltaic power generation system, abbreviated as PV, refers to a power generation system that uses the photovoltaic effect of photovoltaic cells to directly convert solar radiation energy into electrical energy. Photovoltaic power generation system, abbreviated as PV, refers to a power generation system that uses the photovoltaic effect of photovoltaic cells to directly convert solar radiation energy into electrical energy. An independent photovoltaic power generation system consists of a solar photovoltaic array, a battery pack, a charging controller, a power electronic converter, a load, etc. Its working principle is that the solar radiation energy is first converted into electrical energy through the photovoltaic array, and then converted by the power electronic converter to power the load. At the same time, the excess electrical energy is stored in the energy storage device in the form of chemical energy after passing through the charging controller.

In the application of traditional photovoltaic power generation devices, packaging materials are needed to package them. However, the existing packaging materials are prone to displacement or loosening due to vibration during installation after pouring. Therefore, we propose a photovoltaic packaging material to solve the above problem. Utility Model Content
