Description

Technical Field

[0001] The utility model relates to the field of photovoltaic solar energy, in particular to an anti-sag aluminum alloy frame for a solar photovoltaic panel. Background Art

[0002] Photovoltaic power generation is based on the principle of photovoltaic effect, using solar cells to directly convert sunlight energy into electrical energy. Whether it is used independently or connected to the grid, the photovoltaic power generation system is mainly composed of three parts: solar panels (assemblies), controllers and inverters. They are mainly composed of electronic components, but do not involve mechanical parts. Solar power generation is divided into photothermal power generation and photovoltaic power generation. Regardless of production and sales volume, development speed and development prospects, photothermal power generation cannot catch up with photovoltaic power generation. It may be because photovoltaic power generation is more popular and less exposed to photothermal power generation. Usually, what people call solar power generation often refers to solar photovoltaic power generation, referred to as photovoltaic.
