A Photovoltaic Photothermal Integrated System

Abstract

The invention discloses a photovoltaic and photo-thermal integrated system. The photovoltaic and photo-thermal integrated system comprises a plurality of photovoltaic and photo-thermal subsystems and a heat collection water tank; each photovoltaic and photo-thermal subsystem comprises a left-side photovoltaic plate, a heat collection pipe and a right-side photovoltaic plate; each heat collection pipe is connected with the heat collection water tank; each left-side photovoltaic plate is leftward inclined for a certain angle and is located at the lower left side of the corresponding heat collection pipe; a left-side upper ventilation hole and a left-side lower ventilation hole are formed in an upper end part and a lower end part of each left-side photovoltaic plate; a left-side metal water pipe is arranged at the position of the upper part of an inner cavity of each left-side photovoltaic plate; each left-side metal water pipe is connected with the heat collection water tank; each right-side photovoltaic plate is rightward inclined for a certain angle and is located at the lower right side of the corresponding heat collection pipe; a right-side upper ventilation hole and a right-side lower ventilation hole are formed in the upper part and the lower part of each right-side photovoltaic plate; a right-side metal water pipe is arranged at the position of the upper part of an inner cavity of each right-side photovoltaic plate; each right-side metal water pipe is connected with the heat collection water tank. The photovoltaic and photo-thermal integrated system is simple in structure, convenient to mount, high in light utilization rate and low in cost, and integrated application of a photo-thermal system and a photovoltaic system is realized.

Description

technical field [0001] The invention relates to the fields of photovoltaic, photothermal and renewable energy utilization, in particular to a photovoltaic and photothermal integrated system. Background technique [0002] Under standard conditions (radiation intensity of AM1.5 solar spectrum 1000W / m2, battery temperature 25°C), the photoelectric conversion rate of photovoltaic modules is 8% to 17%, and more than 80% of solar energy is not used, and the photovoltaic modules Temperature also has a great influence on its power generation efficiency. Under a certain light intensity, when the temperature of the photovoltaic module itself rises, its power generation power decreases. How to reduce the temperature of photovoltaic modules and improve power generation efficiency is a technical problem that needs to be solved urgently. [0003] The patent number is 201020140526.7, and the name is a photovoltaic square array waste water cooling recovery system integrated with the buildi...

Problems solved by technology

[0005] Photovoltaic systems and photothermal systems are often used separately at present, and their sunlight utilization rates are not high. There is no corresponding technology to integrate the two, so that their sunlight utilization rates can be improved, and they can promote each other.
