Solar heating
solar energy is an inexhaustible clean green energy, and solar energy is used to divide photovoltaic and light heat. Photovoltaic (PV): it is used to generate electricity. A solar panel is a device that converts light energy into electrical energy, and every M2 solar panel can generate about 100W. More used for lighting. Light heat: it is the equipment that converts light energy to heat, and the collector is a light and heat conversion device. It is divided into flat plate and concentrating type. The heat transfer medium is liquid or gas. The heat of each M2 collector is equivalent to the 300-500W energy.
