In the existing traditional heating solutions, for electric heating equipment: the requirement for electric power is high for heating with electric energy, the requirements for electric power infrastructure are relatively high, and the cost is relatively high; for heating equipment such as coal combustion: there is air pollution, poor environmental sanitation, and it requires daily maintenance by personnel, with high maintenance costs and poor convenience.

[0005] In order to solve the deficiencies of the prior art, the utility model provides a solar photovoltaic and solar-thermal collection device and system. By using a finished solar panel, a heat medium pipe and a heat insulation material are installed on its back. When the sun shines on the front of the assembly, while the photovoltaic module generates electricity, heat energy can be generated. Under the action of the heat insulation layer, the loss of heat energy is greatly reduced. Using the heat medium to transport the heat energy to the heat exchange equipment can realize the effective utilization of the heat energy.
