The present invention provides a control method of a compound photovoltaic and photo-thermal integration system, belonging to the solar power generation application field and the automatic control field. A solar energy controller is connected with a photovoltaic and photo-thermal integration member, a storage battery and an inverter; a temperature controller is connected with a wind valve, a water pump and K-type thermocouples; a fan is connected with the photovoltaic and photo-thermal integration member through an air channel; a heat storage water tank is connected with the photovoltaic and photo-thermal integration member through a water flow channel and the water pump; the K-type thermocouple K1 detects the current temperature T1 of the photovoltaic and photo-thermal integration member; and the K-type thermocouple K2 detects the current temperature T2 of heat water in the heat storage water tank, and the temperature controller is connected with the K-type thermocouple K1 and the K-type thermocouple K2. The temperature controller is mainly employed to perform real-time temperature feedback of the K-type thermocouples to control the opening and closing of the water pump and the wind valve to realize cooling of the photovoltaic and photo-thermal integration member through two mediums consisting of water and air so as to solve the problem that current photovoltaic products cannot be applied in all seasons.
Description
technical field [0001] The invention belongs to the application field of solar power generation and the field of automatic control, and specifically relates to a control method of a composite photovoltaic-photothermal integrated system, which can simultaneously use water and air to cool photovoltaic-photothermal integrated components, so that it can be used throughout the year. use. Background technique [0002] With the in-depth study of solar cell preparation and the support of relevant photovoltaic policies, the research and development and application of solar products have been widely promoted. However, due to the temperature effect of the solar cell itself, the output of the actual photovoltaic panel is much smaller than the nominal capacity value, so it is particularly necessary to study the heat dissipation of the solar cell. The photovoltaic photothermal integrated system has quickly won the favor of scientists all over the world because of its waste heat reuse. ...
