Design of domestic photovoltaic cell tracking device and electric heating system

Under the dual pressure of the energy crisis and environmental pollution, it is necessary to use the solar energy instead of coal energy in heating system, especially in rural area. A kind of photovoltaic automatic tracking device is designed and the solar power system is applied in domestic heating system. In the designed tracking PV device, the height and the angle are both variable due to the position of the sun. The design is based on image analysis method, including the shade image acquisition and image analysis process. It can keep the most efficiency in solar energy utilization and the most power generation. In the solar energy aided heating system, the far infrared heating flexible plate is used as energy conversion carrier. This kind of fiber has some advantages in the electric-heat efficiency conversion and the voltage limited scores. The pebble and gravel layer is used as a high capacity slow diffusion of heat storage body. In winter, the solar power generation is used for the power supply of the heat system. In summer, the solar power generation can be connected to the power grid as the compensation of the utility energy system.
