Background technique

Solar energy is a clean and non-polluting renewable energy. Fully exploiting and utilizing solar energy can not only save conventional energy that is increasingly depleted, but also reduce pollution and protect the environment.

Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. In order to obtain the best power output of the photovoltaic power generation device, the solar cell modules must be installed in a certain orientation in combination with the natural environmental conditions such as the construction site, the month and the season, so that the solar cell modules can face or basically face the sun, so that Ensure that solar photovoltaic panels get the most light resources, so that their power generation efficiency is at its best.

At present, the installation methods of solar photovoltaic modules are nothing more than fixed type and adjustment tracking type. Although the fixed installation method has the advantages of simple structure and convenient installation and fixing, because it cannot be tracked and adjusted according to the sun's azimuth, the power generation efficiency is low, and it is difficult to give full play to the power generation efficiency of the photovoltaic power station. The dual-axis tracking installation method in the adjustment tracking type can track the azimuth of the sun. Although it has the highest power generation efficiency, the adjustment structure is complicated, the failure rate is high, and it needs to consume more driving power.
