The article points out that photovoltaic solar power generation is a clean energy source, and the power generation process does not emit pollutants, nor does it cause pollution to the atmosphere, water sources, and soil. Throughout its entire lifecycle, there may be certain environmental impacts during the production, installation, and maintenance phases, but they can be effectively controlled through technological advancements and scientific planning and management. In the future, its environmental friendliness will continue to improve.

This article focuses on the impact of high summer temperatures on the efficiency of solar panels. It explains that the standard testing temperature for solar panels is 25°C, with an optimal operating range of 15-35°C. Efficiency significantly declines at 65°C, and this temperature effect is related to the "temperature coefficient." The article also provides mitigation measures: ensuring ventilation space during installation and selecting products with lower temperature coefficients to maintain power generation efficiency.

German and Belgian scientists have jointly developed a perovskite/CIS stacked solar cell with a photoelectric conversion efficiency of 24.9% (nearly 25%), setting a record for similar technologies. This battery is lightweight and flexible, and can be applied in scenarios such as construction, automobiles, and portable devices. Stacking technology can absorb sunlight of different wavelengths, and this type of battery is expected to increase efficiency to over 30% in the future.

The article explores the impact of snow accumulation in cold seasons on solar panels and the corresponding countermeasures. Snow accumulation will significantly reduce power generation, and users without grid connection will be more affected, but snow reflection can slightly improve performance. The coping strategies include regular snow removal, increasing the angle of panel installation, and reserving space below the panel to ensure power generation efficiency.

The article introduces the service life and influencing factors of solar panels. The dropper board in crystalline silicon solar panels is used for about 5 years, and the laminated board that meets TUV standards can last up to 25 years; The lifespan of amorphous silicon solar panels is 10-15 years. Lighting, temperature, component quality, and maintenance can affect its performance, with an overall expected lifespan of over 20 years. Reasonable selection and maintenance can ensure profitability.
