Abstract

The invention relates to the photovoltaic power generation technology, and particularly relates to a system and a method for realizing photovoltaic power generation through ground reflection. According to the technical scheme, a reflective plate is arranged on a horizontal ground region corresponding to the back surface of a photovoltaic two-sided power generation module; and the relative angle between the reflective plate and the horizontal ground is adjusted to enable the reflective plate to reflect the received solar incident light to the back surface of the photovoltaic two-sided power generation module. Consequently, utilization rate on ground reflection and scattered light of the photovoltaic two-sided power generation module can be dramatically improved, and the conversion efficiency is greatly improved; and meanwhile, reflectivity of a roof can be improved when the system is used on the roof so as to further reduce temperature in the room, so that air conditioner expenditure in summer can be effectively saved.

Description

technical field [0001] The invention relates to solar photovoltaic power generation technology, in particular to a system and method for photovoltaic power generation using ground reflection. Background technique [0002] At present, in photovoltaic application technology, crystalline silicon photovoltaic module products occupy the mainstream position in the market due to its low cost and high conversion efficiency. The basic principle of photovoltaic technology is to use photovoltaic modules to absorb the irradiated energy of the sun and convert it into electrical energy. At present, conventional photovoltaic modules can only use one side to absorb solar radiation, so when installed and used, they will absorb as much solar radiation as possible through the installation angle. As the pollution of traditional energy to the environment has attracted more and more global attention, and the reserves are decreasing and the price is increasing, the development and utilization of r...
