Background

New energy power generation is always a very important field in China, the solar power generation industry develops rapidly in the years, solar energy is clean energy, and the environment cannot be polluted in the process of converting the solar energy into electric energy. Therefore, photovoltaic power stations are built in large quantities in various regions. Photovoltaic module products are also in double demand.

Photovoltaic power generation is a technology of directly converting light energy into electric energy by using the photovoltaic effect of a semiconductor interface. The photovoltaic power generation system mainly comprises a solar panel (assembly), a controller and an inverter which are mainly composed of electronic components and do not relate to mechanical parts, so that the photovoltaic power generation equipment is extremely refined, reliable, stable, long in service life and simple and convenient to install and maintain. Photovoltaic power generation has the advantage of being less geographically constrained because sunlight generally illuminates the ground; the photovoltaic system also has the advantages of safety, reliability, no noise, low pollution, no need of consuming fuel and erecting a power transmission line, on-site power generation and supply, and short construction period.

A key element of photovoltaic power generation is the solar cell. The solar cells are connected in series and then are packaged and protected to form a large-area solar cell module, and then the photovoltaic power generation device is formed by matching with components such as a power controller and the like. The solar cell panel (assembly) is composed of tempered white glass, EVA (ethylene vinyl acetate), a back panel, a silicon cell sheet, a tin coating tape, a Roman adhesive tape (silica gel), an aluminum frame and a junction box, and the solar cell assembly (also called as a solar cell panel) is a core part in a solar power generation system and is also the most important part in the solar power generation system. The solar energy is converted into electric energy, or the electric energy is sent to a storage battery for storage, or a load is pushed to work. It is critical to maintenance of the photovoltaic module.

Most photovoltaic power plants all can adopt the briquetting to fix photovoltaic module on the cross arm, and some photovoltaic power plants are because the cross arm is short, can't utilize the briquetting to fix photovoltaic module, consequently use the screw to be connected the aluminum alloy frame and the cross arm (U type groove) of subassembly, and these power plants have be in the strong wind weather throughout the year, because the subassembly erects higher, lead to the superiors' subassembly to hang down blowing of strong wind, the easy fracture of aluminum alloy frame screw department of subassembly, the phenomenon of tumbling takes place, and can shelter from lower floor's subassembly, can damage lower floor's subassembly when serious, it is comparatively serious to influence the generated energy.
