Photovoltaic module used in cold environment in northern areas

Abstract

The invention discloses a photovoltaic assembly used in a cold environment in northern areas in the field of photovoltaic technology, and the photovoltaic assembly comprises a support assembly which comprises a pedestal, wherein the top surface of the pedestal is provided with a semi-cylindrical guide support, and the semi-cylindrical guide support is provided with a guide groove; a photovoltaic module which comprises a frame arranged on the semi-cylindrical guide bracket, wherein a photovoltaic panel is mounted on the frame; and a maintenance assembly which is arranged on the semi-cylindricalbracket. According to the invention, accumulated snow covering the photovoltaic panel is sucked into the barrel through the negative pressure effect, snow particles can be separated from the surfaceof the photovoltaic panel outwards, maintenance operation is conducted on the premise that the snow particles do not rub with the surface of the photovoltaic panel, and the problem that the photovoltaic panel is scratched due to the fact that the hardness of the snow particles is increased due to the too low temperature is avoided; the sucked accumulated snow is rolled into rolls and wound on thewinding roller, and is pushed out through the push plate after the surface of the photovoltaic panel is maintained, so that the maintenance effect is good, and the service life of the photovoltaic module in a northern cold environment is prolonged.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a photovoltaic module used in cold environments in northern regions. Background technique [0002] Photovoltaic: It is the abbreviation of solar photovoltaic power generation system. It is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. There are two modes of independent operation and grid-connected operation. At the same time, the classification of solar photovoltaic power generation systems, one is centralized, such as large-scale Northwest ground photovoltaic power generation systems; the other is distributed (with >6MW as the boundary), such as industrial and commercial enterprise factory roof photovoltaic power generation systems, residential roof photovoltaic power generation systems.

Problems solved by technology

[0003] When photovoltaic modules in cold northern regions are used, heavy snow often occurs, resulting in the problem of snow accumulation on the surface of photovoltaic panels. At present, they are cleaned manually with brushes or other tools. However, due to the low temperature in the air, snow It is easy to quickly condense into snow particles, resulting in high hardness. When using a brush to clean, it is easy to scratch the surface of the photovoltaic panel, which will lead to the problem of shortening the service life of the photovoltaic panel.
