Low-power concentrating photovoltaic module

Abstract

The invention provides a low-power concentrating photovoltaic module which comprises a lower-power concentrating system, a photovoltaic battery pack and a heat dissipating device making good heat conduction contact with the photovoltaic battery pack. The low-power concentrating photovoltaic module is characterized by being provided with a glass tube outer shell with the two ends closed, and the lower-power concentrating photovoltaic module can track the incident solar rays within a large angle range in a non-movement mode and perform high-efficiency concentrating power generation. The low-power concentrating photovoltaic module has the advantages of being low in cost, good in sealing performance, good in weather resistance, high in mechanical strength, strong in self-supporting force and long in service life.

Description

technical field [0001] The invention relates to a photovoltaic power generation assembly, in particular to a non-motion tracking tubular low-magnification photovoltaic assembly. Background technique [0002] As a renewable green energy, solar energy has broad development prospects, and solar photovoltaic power generation has become an important method of new energy utilization. In the solar photovoltaic power generation system, the photovoltaic power generation module is the main device to realize photoelectric conversion, and it is also the largest part of the cost of the photovoltaic power generation system. The current mainstream photovoltaic modules are all plate-shaped photovoltaic modules, which directly encapsulate photovoltaic cells in glass plates and receive sunlight with normal irradiance intensity to generate electricity. On the one hand, most of the cost of photovoltaic modules comes from photovoltaic cells. It is difficult to significantly reduce the cost of b...
