Hybrid photovoltaic-thermal solar collector

Abstract

The invention discloses a hybrid photovoltaic-thermal solar collector which is mainly applied to synchronous collection of the photothermal energy and the photovoltaic energy of solar energy. The hybrid photovoltaic-thermal solar collector consists of a support 1, bearings 2, 19, a one-dimensional tracking system 3, a hydraulic driving rod 4, reflectors 5, 6, a photovoltaic-thermal collection box shell, a heat-insulating layer, a vacuum glass light-permeable cover plate, a plurality of narrow slits, a receiving plate 11, a plurality of photovoltaic cells, a heat-transfer metal square water pipe, a self-control water pump 18, a water inlet, a water outlet and a photovoltaic cell output lead. The hybrid photovoltaic-thermal solar collector is characterized in that the one-dimensional tracking system is arranged in a horizontal and east-west direction, and a plurality of metal sheets are vertically arranged on the receiving plate 11 to form the narrow slits to reflect solar beams for many times, so that the reflective index is largely reduced. According to the hybrid photovoltaic-thermal solar collector disclosed by the invention, the purpose of solar energy condensation collection can be realized; the structure is simple, the cost is reduced, the cost performance is improved, and the commercial operation of the scale, industrial solar energy condensation collection comes true.

Description

technical field [0001] The invention relates to a photothermal and photoelectric integrated solar collector, which is mainly used for simultaneous collection of solar photothermal and photoelectricity. Background technique [0002] At present, the general solar collectors, especially the photovoltaic cell arrays of domestic water heaters and rooftop photovoltaic power generation projects, are fixedly placed, and some are fixed to receive solar energy in a flat or oblique manner according to different situations. As we all know, due to the change of the earth's revolution and rotation around the sun, it is impossible to collect high-energy solar energy by concentrating all-weather with fixed collectors; and concentrating solar energy can convert low-energy solar beams into high-energy solar beams to be collected application. For thousands of years, human beings have continued to explore and successfully applied Fresnel lens, optical funnel concentrating, and trough concentra...

Problems solved by technology

This will cause extreme inconvenience to users

Three to five years later, due to the inevitable phenomenon of mechanical aging, wind and rain erosion and rust, the failure rate of the device system will increase, and the repair and maintenance work will consume a lot of manpower and material resources, making it difficult for producers and users to bear.

[0004] The above-mentioned problems are the reasons why solar spotlight tracking technology has been unable to enter large-scale applications. It is generally believed in the industry that it is difficult to solve by improving the design and manufacturing level of mechanical systems
