Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation roofs, in particular to a photovoltaic power generation roof that is arranged inclined. Background Art

[0002] With the advancement of science and technology, photovoltaic power generation technology has developed rapidly. The research and development of high-efficiency solar panels has continuously improved the photoelectric conversion efficiency. At the same time, the stability and reliability of the photovoltaic system have also been significantly improved, which provides a technical basis for the inclined photovoltaic power generation roof. As an important part of the building, the roof has a large usable space. By setting the photovoltaic power generation roof at an angle, this space can be fully utilized to collect and utilize solar energy, which not only reduces the occupation of land resources, but also improves the energy utilization efficiency of the building.

[0003] This kind of inclined photovoltaic power generation roof still has the following defects when in use: the roof structure is single, the strength and stability are insufficient, and it is difficult to withstand the test of extreme weather or long-term use. The power generation efficiency of the photovoltaic panels is limited by environmental factors such as temperature, dust accumulation, etc., resulting in the actual power generation being lower than the theoretical value. The waterproof performance is poor and it is easy for water to seep in and cause internal damage. The photovoltaic panels have poor heat dissipation effect and the power generation efficiency is significantly reduced under high temperature conditions. The utilization rate of sunlight is not high, and part of the light is not effectively utilized and is reflected or scattered. The photovoltaic panels are easily damaged by vibrations caused by natural factors such as earthquakes and wind vibrations. The cleaning and maintenance costs are high and dust and dirt need to be cleaned manually regularly. The light transmittance of the glass material is low, resulting in a decrease in the light energy received by the photovoltaic panels. The thermal insulation performance is poor and the photovoltaic panels are easily affected by heat loss. Utility Model Content
