Problems solved by technology

However, only part of the solar energy incident on the photovoltaic panel is converted into electrical energy, and the rest is converted into thermal energy and stored in the photovoltaic panel. The heat accumulated in the battery will degrade the performance of the photovoltaic battery, reducing the photoelectric conversion efficiency and usage of the photovoltaic panel. life

[0003] At present, the commonly used heat dissipation method is to directly spray cold water on the photovoltaic panel to cool down. Although this method can achieve a cooling effect, long-term water spray cooling treatment will easily form water stains on the surface of the photovoltaic panel, which will block the light and reduce the temperature of the photovoltaic panel. The light receiving rate affects the photoelectric conversion efficiency of photovoltaic panels
