The invention discloses a solar thermal power generation system and method based on the temperature difference between day and night. The solar thermal power generation system includes a heat collection system, a heat transfer system, a heat storage and heat exchange system, a power generation system and a thermoelectric power generation device; the heat collection system, The heat transfer system, the heat storage and heat exchange system, and the power generation system are connected in sequence to transmit the heat collected by the heat collection system to the heat storage and heat exchange system through the heat transfer system, and the power generation system utilizes the collected heat for daily production. The thermoelectric power generation device is connected to the heat storage and heat exchange system, and is used for generating electricity at night by utilizing the heat stored in the heat storage and heat exchange system. A thermoelectric power generation device is integrated outside the heat storage and heat exchange system, which can use the temperature difference between day and night to generate electricity, reduce unnecessary heat loss at night, and improve the ability to efficiently utilize solar energy.
Description
