SYSTEM USING SOLAR ENERGY

摘要

Provided is a system using solar energy in which solar energy use efficiency is improved over the prior art. The system using solar energy is provided with a solar cell (1) and obtains power from the solar cell (1), wherein the system using solar energy is characterized by being provided with the following: a first heat exchanger (2) for cooling the solar cell (1); a heat pump (3) connected to the first heat exchanger (2); a circulation pump (4) for causing a heat medium to circulate between the first heat exchanger (2) and the heat pump (3); and a flow rate control unit (5) for changing the flow rate of the circulation pump (4). Or, the system using solar energy is characterized by being provided with the following: a first heat exchanger (2) for cooling the solar cell (1); a second heat exchanger (3e) connected to the first heat exchanger (2); a circulation pump (4) for causing a heat medium to circulate between the first heat exchanger (2) and the second heat exchanger (3e); and a flow rate control unit (5) for changing the flow rate of the circulation pump (4).
