Solar thermal and photovoltaic are respectively integrated with multiple energy sources such as air source heat pump, gas, biomass, etc., and can be applied to heating, cooling, hot water systems, industry, and agriculture. It better solves the instability and intermittent problems of solar energy sources, and takes into account the problems of economy and energy saving effects.Prioritize the use of solar energy. When the solar energy is insufficient, the system automatically chooses to start the auxiliary heat source to supplement heat, and realizes all-weather operation. Multi-energy complementary, energy cascade utilization, low temperature and high efficiency, realizing multi-energy and multi-efficiency utilization of cold, heat and electricity.
