Do solar panels emit radiation?

Photovoltaic solar panels do not produce radiation. But light pollution from photovoltaic solar panels has the potential to have health effects.

Photovoltaic solar power generation, the principle is that light energy is directly converted into electrical energy. The advantage is that solar energy can be used everywhere and can supply electricity nearby. Photovoltaic power generation is a technology that directly converts light energy into electrical energy by utilizing the photovoltaic effect of the semiconductor interface. The key element of this technology is the solar cell. After the solar cells are connected in series, they can be packaged and protected to form a large-area solar cell module. Flat-shaped solar cell modules are photovoltaic solar panels.

Light pollution is a new source of environmental pollution after waste gas, waste water, waste residue and noise, mainly including white light pollution, artificial daylight pollution and color light pollution. Light pollution is threatening people's health. In daily life, people's common light pollution is mostly the dizziness of pedestrians and drivers caused by the reflection of mirrored buildings, and the discomfort caused by unreasonable lighting at night.

There is no clear basis and conclusion for the impact of light pollution on health, and there is no relevant evaluation standard. But some studies suggest that light pollution has the potential to damage eyes, induce diseases and affect people's emotions. It is generally believed that light pollution may cause headaches, fatigue, decreased sexual performance, and increased stress and anxiety. Animal model studies have demonstrated adverse effects on mood and anxiety when light is unavoidable.

The light pollution of photovoltaic power generation solar panels is easy to avoid. It can be avoided by choosing low-reflection photovoltaic power generation solar panels, adjusting the reflection of photovoltaic power generation solar panels to unmanned areas, blocking reflections, and installing personnel paying attention to wearing sunglasses.
