Roof concentrating photovoltaic power generation device

Abstract

The invention provides a roof concentrating photovoltaic power generation device. The photovoltaic power generation device comprises an inclined roof used for supporting the photovoltaic power generation device, photovoltaic power generation assemblies used for photovoltaic power generation and a light condensation mechanism used for conducting light condensation to guide light to the photovoltaicpower generation assembly. The photovoltaic power generation assemblies are arranged on the two sides of a roof, the light condensation mechanism is arranged at the highest position of the roof, andthe photovoltaic power generation assemblies on the two sides of the roof are symmetrically distributed with the center line of the light condensation mechanism as the symmetric line. Research and analysis are carried out according to problems existing in existing roof photovoltaic power generation; a photovoltaic power generation device capable of concentrating light in multiple aspects is designed; and the photovoltaic power generation device can adapt to the problem that temperature difference is generated due to condensation, so that the problems that when a common photovoltaic power generation device is used on an inclined roof, lighting is easily limited by time, lighting is poor in a long time in one day, the photovoltaic power generation efficiency is low, and a common adjusting device has certain safety problems are effectively solved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a rooftop concentrating photovoltaic power generation device. Background technique [0002] Photovoltaic power generation technology has become very popular and can be installed in many places with good lighting. Installing photovoltaic power generation devices on house roofs is not easily blocked by tall buildings and has high power generation efficiency. However, for some special roofs, such as triangular-shaped The heat insulation layer of the slope and the sloping roof often have the problem that the lighting is limited by time. For example, in the morning, the photovoltaic power generation device on one side has good lighting and high power generation efficiency, while the other side cannot be illuminated by light. It is very low, and it may turn over in the afternoon, and for the same photovoltaic power generation module, there is always the problem of...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a roof concentrating photovoltaic power generation device, which solves the problem that when a general photovoltaic power generation device is used on a sloping roof, the daylighting is easily limited by time, and the daylighting is relatively slow for a long time in a day. Poor, photovoltaic power generation efficiency is low, and there are certain safety problems in commonly used regulating devices
