[0001] The invention relates to the field of solar energy technology, and in particular to a sewage removal and cooling heat collection device for household distributed photovoltaic power stations. Background Art

[0002] Energy and environment are one of the current global focus issues. Solar energy is highly valued as a clean energy source. The application prospects of household distributed photovoltaic power stations are broad, and their photoelectric conversion relies on solar panels. Solar panels are devices that absorb solar energy and convert it into electrical energy.

[0003] Since solar panels are placed outdoors for a long time, the hot spot effect caused by flying birds, dust, and fallen leaves will damage the working life of the solar panels, and the acidic and alkaline dust will corrode the surface of the solar panels. Both of these situations will weaken the light intensity on the surface of the solar panels, weaken the photoelectric effect, and reduce the photovoltaic power generation. Therefore, dust and other dirt will not only reduce the power generation efficiency of the solar panels, but also shorten the life of the solar panels.

[0004] Most of the solar radiation received by solar panels is dissipated in the form of heat energy, causing the temperature of the solar panels to rise and reducing their photoelectric conversion efficiency. At the same time, overheating conditions will also significantly reduce the service life of the solar panels.

[0005] Therefore, a sewage cooling and heat collection device for household distributed photovoltaic power stations is proposed to solve the above problems. Summary of the invention
