Cooling, cleaning and detachable mounting device and method for building roof photovoltaic power generation panel

Abstract

The invention provides a cooling, cleaning and detachable mounting device and method for a building roof photovoltaic power generation panel, and relates to the field of photovoltaic building integration. The device comprises a cooling and cleaning unit composed of a cleaning part, a cooling part and a first driving part; the cooling part is provided with a temperature sensor installed on the back face of the photovoltaic power generation panel, and when it is monitored that the temperature is too high, cooling and cleaning of the photovoltaic power generation panel are started. Wherein the cleaning part is provided with cleaning cotton, the cooling part is provided with a water spraying mechanism with the water spraying direction facing the cleaning cotton, the water spraying mechanism sprays water to the cleaning cotton through deformation of a plastic telescopic pipe arranged in the water spraying mechanism, then the first driving part drives the cleaning cotton to reciprocate on the light receiving face, and then the light receiving face achieves the cooling and cleaning effects in a water evaporation and heat absorption mode. The photoelectric conversion efficiency of the photovoltaic power generation panel is improved; the photovoltaic power generation panel is detachably installed on the building roof, installation and disassembly are simple and fast, and the installation and disassembly cost is remarkably saved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic building integration, in particular to a device and method for cooling, cleaning and detachable installation of photovoltaic power generation panels on building roofs. Background technique [0002] One of the main tasks of a carbon-neutral strategy is to achieve a transition from a carbon-based electricity system based on fossil energy to zero-carbon electricity based on renewable energy. Solar photovoltaic power generation is one of the main renewable power sources in the future, and the exterior surface of a building with a huge volume is a space resource for the development of distributed photovoltaics. The rapid decline in the cost of photovoltaic modules has made building integrated photovoltaics more feasible. [0003] Solar cells are in the best working condition at 25°C. However, the temperature of solar photovoltaic panels is usually higher than room temperature (25°C) during operat...
