[0002] As a clean and renewable energy, photovoltaic power generation can directly power the lighting, illumination, water pump and other equipment in facility agriculture, effectively reducing carbon emissions in agricultural production. Currently, the application of photovoltaic modules in sunlight greenhouses to improve the greenhouse light environment and increase the utilization rate of renewable energy has attracted attention.

[0003] Photovoltaic power generation can save energy and reduce emissions, and does not produce any greenhouse gas emissions during the process, which helps to slow down global warming. It can reduce energy costs, although the initial installation cost is high, but in the long run it can significantly reduce electricity expenses. It can improve energy self-sufficiency, to some extent, it can reduce the dependence on traditional energy and improve energy security. It can increase the value of real estate, environmentally friendly and energy-saving houses are increasingly popular among home buyers, and houses with photovoltaic systems have higher market value. It has government subsidies and tax incentives, many regions provide subsidies or tax deductions for families installing photovoltaic power generation systems, further reducing installation costs. It is green and environmentally friendly, photovoltaic power generation does not consume fuel and does not emit greenhouse gases and other waste gases, and is harmless to the environment. It has universality and flexibility, photovoltaic power generation systems can be installed on the roof, wall and other positions of buildings, and can adapt to various environments and needs.

[0004] However, the initial investment in photovoltaic power generation is high, and the purchase and installation cost of photovoltaic systems is still not low, which is a considerable expense for some families. Affected by weather and geographical location, photovoltaic power generation will decrease on rainy days or in winter when there is insufficient sunlight, and the difference in sunshine duration and intensity in different regions will also affect the power generation efficiency. It requires a certain space, and enough roof or yard space is needed for the installation of photovoltaic panels, which may be a major problem for residences with limited space.
