Abstract

The invention discloses a photovoltaic power generation device. The photovoltaic power generation device comprises a photovoltaic support, a photovoltaic array is arranged on the photovoltaic support, and a reflection plate is arranged between two adjacent rows of modules and is used for reflecting sunshine to the modules in the second row. The reflection plate is composed of a light guide plate and a reflection film or a spectral selection thin film. The back face of the light guide plate is provided with a microstructure which is covered with the reflection film or the spectral selection thin film, and more sunshine is selectively and evenly reflected to the surfaces of the modules. When the inclination angle of the reflection plate is 28.7 degrees, the generating capacity of the photovoltaic modules can be improved by 21.94 percent, and the cost of the reflection plate is only 0.6 Yuan/W. By means of the arrangement form of the photovoltaic power generation system additionally provided with the reflection plate, the power generation cost can be reduced while the effective power generating capacity of the system is improved, and efficient cost performance is achieved.

Description

technical field [0001] The invention relates to a photovoltaic power generation system, in particular to a photovoltaic power generation device for improving the effective power generation by changing the structural layout of the existing photovoltaic power generation system. Background technique [0002] With the increasing energy crisis and environmental problems, photovoltaic power generation technology has been paid more and more attention by countries all over the world. Solar photovoltaic power generation has developed from being a low-power power source to being a grid-connected power generation for public power. Its application range covers almost all fields of electricity consumption, such as meteorology, communications, long-distance pipelines, roads, railways, etc. Today's solar energy is not just a "supplementary energy source", but is gradually transitioning to an "alternative energy source". [0003] At present, the low efficiency of photovoltaic power generat...
