Solar power generating and water heating integrative machine

Abstract

The invention relates to the technical field of solar energy, and provides a solar power generating and water heating integrative machine, which comprises an inclined support, a circulating water tank, a plurality of solar cell slices and a plurality of glass water pipes, wherein a plurality of strip-shaped cell slice arrays are formed by the plurality of solar cell slices; the number of the strip-shaped cell slice arrays is equal to the number of the glass water pipes; the strip-shaped cell slice arrays are longitudinally arranged on the inclined support at intervals; the glass water pipes are longitudinally arranged on the inclined support; each glass water pipe is arranged above a corresponding strip-shaped cell slice array; and the lower ends of the glass water pipes are closed, and the upper ends of the glass water are connected with the circulating water tank. The solar power generating and water heating integrative machine has the advantages that the glass water pipes are arranged above the solar cell slices, so that effects of light condensation and temperature reduction are achieved, and a solar cell panel can keep a normal temperature working curve on the basis of keeping the largest light condensation multiple.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic power generation and solar water heaters, in particular to a solar power generation and hot water integrated machine. Background technique [0002] In recent years, solar photovoltaic power generation technology has been widely used in the field of new energy, and its materials are mainly monocrystalline silicon and polycrystalline silicon. In order to improve the utilization rate of solar cells, people use various forms of reflective concentration or refraction concentration combined with solar panel arrays to achieve the desired results. Solar reflective concentrating technology has developed many forms of devices, including: trough parabolic concentrating, rotating parabolic concentrating, compound parabolic concentrating, spherical concentrating, circular involute concentrating and V-shaped concentrating, etc. In the field of solar refraction and concentrating, Fresnel lenses are m...

AI Technical Summary

Problems solved by technology

Refractive concentrating has the disadvantages of high cost, large loss of concentrating light, uneven concentrating, difficult manufacturing, and low light transmittance.

In order to compensate for the overheating of solar panels caused by concentrated light, the water cooling system added will greatly increase the cost of the entire system, so most of them are still in the experimental stage at present.
