Description

A solar-powered combined power supply device technical field The invention relates to a combined power supply device driven by solar energy. Background technique As an important energy source among renewable clean energy sources, solar energy is inexhaustible, and more and more attention has been paid to its development and utilization. Conventional use of solar energy is mainly focused on the application of domestic hot water, and more and more attention is currently being paid to solar power generation and composite utilization. Solar power generation includes photothermal power generation and photovoltaic power generation, both of which have certain application markets. In solar photothermal power generation, solar collectors are used to collect solar energy to heat the circulating working medium - heat transfer oil. Heat transfer oil has the characteristics of large heat capacity, strong heat conduction ability, and high boiling point. Compared with conventional wate...

Problems solved by technology

In existing technologies or devices, the proportion of thermal energy converted into mechanical energy from solar energy is limited, and a large part of the energy is directly dissipated by the condenser without effective use, causing certain thermal pollution to the environment. The heat source used for hot water can realize the cascade utilization of heat energy; at the same time, most systems only output a single electric energy, and the overall efficiency is not high
