Solar energy is a widely distributed and inexhaustible "green" renewable new energy, which is one of the best solutions to the energy crisis in the world. However, the conversion efficiency of photovoltaic cells in large-scale solar applications is not high, and the cost is very high. Therefore, in order to increase the power generation capacity and efficiency of solar power generation, automatic tracking power generation devices should be used to replace fixed solar photovoltaic panels and other solar equipment. This design proposes a two axis solar tracking system based on the Internet of Things cloud platform. This system uses the sun viewing motion tracking method to drive photovoltaic panels in horizontal and vertical directions to track the sun. The preset tracking angle of the system is based on the sun azimuth angle and altitude angle operation rules calculated and collected by the sun angle calculation software, and combined with weather data to find the best angle for real-time tracking. This design will elaborate the design process from the aspects of system overall scheme design, hardware circuit design and host computer software development.
