Double-sided photovoltaic power generation device with free reflection curved surface

Abstract

The invention discloses a double-sided photovoltaic power generation device with a free reflection curved surface, and the device comprises a double-sided photovoltaic module and a back reflector which are arranged in a mutually inclined manner, and the front end of a back reflector support is hinged with a front reflector support and a front reflector. The mirror surface of the front reflecting mirror is an optical free-form surface capable of uniformly reflecting reflected light to the back surface of the double-sided photovoltaic module, and a front reflecting mirror driver is hinged to the front reflecting mirror bracket; the rear end of the back mirror bracket is hinged with a rear reflecting mirror bracket and a rear reflecting mirror, the mirror surface of the rear reflecting mirror is also an optical free-form surface capable of uniformly reflecting reflected light to the back surface of the double-sided photovoltaic module, and the rear reflecting mirror bracket is hinged with a rear reflecting mirror driver; the back mirror support is hinged to the front stand column, and the pitching driver hinged to the rear stand column is hinged to the back mirror support. The double-sided photovoltaic power generation equipment can directly reflect sunlight to the back surface of the double-sided photovoltaic module, and the reflecting mirror surface tracks the sun, so that the double-sided photovoltaic power generation equipment has the characteristic of high power generation efficiency.

Description

technical field [0001] The invention relates to solar photovoltaic power generation equipment, in particular to a single-axis tracking power generation device with double-sided photovoltaic power generation components. Background technique [0002] Photovoltaic power generation is a kind of inexhaustible, green and pollution-free clean energy that converts solar energy into electrical energy by receiving solar radiation energy through photovoltaic cell components. Conventional photovoltaic power generation devices mainly include photovoltaic power generation components and brackets for supporting power generation components. The photovoltaic power generation Its light-receiving front is perpendicular to the sun's rays, and it cannot change the light-receiving area of ​​the photovoltaic power generation module. [0003] Due to the special cell structure and transparent backplane material of the double-sided photovoltaic power generation module, in addition to power generatio...

AI Technical Summary

Problems solved by technology

Its structure is to install a reflector panel under the double-sided photovoltaic module, such as the Chinese utility model patent "double-glass double-sided photovoltaic module bracket", patent number: 201621234370.2, in this patent structure, the reflector panel is affected by the upper photovoltaic module Shading can not or rarely receive direct sunlight, and mainly refracts the surrounding scattered light to the back of the photovoltaic power generation module, so the increase in power generation efficiency and power generation is still very limited

Even if reflectors are installed on the outside of both ends of the double-sided photovoltaic power generation module, as described in the article "Stent Structure and Control of Double-sided Photovoltaic Power Generation" published in the Journal of Wuhan University, Volume 51, No. 8, the front and rear ends of the photovoltaic module There is a reflector, although this structure increases the light-receiving area for sunlight, so that part of the sunlight that is not irradiated on the front of the photovoltaic module is also reflected and irradiated to the back of the photovoltaic power generation module, but because the height of the sun in a day is It is always changing, so the reflected light of the mirror is not always projected to the back of the photovoltaic module, but a lot of reflected light deviates from the back of the photovoltaic module, and the reflected light of the mirror cannot track the back of the photovoltaic module to generate electricity, and the power generation efficiency It is still difficult to improve, and the utilization rate of light energy is still low
