Problems solved by technology

[0003] At present, most solar panels are installed on the roof. Due to long-term use, more dust will accumulate on the solar panels. The coverage of dust directly affects the conversion rate of solar energy. Even if it rains, the solar cells cannot be completely washed away. The dust on the surface of the board will also form gully-shaped strips of mud, which are difficult to wash away only by rainwater. Long-term use has seriously affected its conversion rate of solar energy; in addition, in winter in the north, solar cells are also easy to Snow, which has not melted for a long time, has seriously affected its conversion rate of solar energy

Abstract

The invention discloses a photovoltaic power generation bracket for improving solar energy conversion rate and an installation and construction method thereof, including a solar panel, a bracket body,a scraper and a drive unit, A support body is inclined with respect to the ground, A plurality of rectangular arrays of the solar cell panels are tiled and arranged on the bracket main body, A main body of that bracket is arranged on a drive assembly, the scraper is arranged above the solar cell panel in an inclined direction perpendicular to the bracket main body, and the scraper moves reciprocally along the inclined direction of the bracket main body through the driving assembly, and the scraper is added above the solar cell panel to clean the upper surface of the solar cell panel, reduce dust and other sundries on the solar cell panel, and ensure the conversion rate of the solar cell panel.

Description

technical field [0001] The invention belongs to the field of photovoltaic power generation, and in particular relates to a photovoltaic power generation support for improving the conversion rate of solar energy and an installation and construction method thereof. Background technique [0002] Photovoltaic is defined as the direct conversion of ray energy. In practical applications, it usually refers to the conversion of solar energy into electrical energy, that is, solar photovoltaic. Its realization is mainly through the use of solar panels made of semiconductor materials such as silicon, and the use of light to generate direct current, such as solar energy that can be seen everywhere in our daily life. Battery. Photovoltaic technology has many advantages: for example, it does not have any mechanical moving parts; it does not need any other "fuel" except sunlight, and it can work under direct sunlight and oblique sunlight; and it is also very convenient and flexible in ter...
