Photovoltaic solar panels do not produce radiation. But light pollution caused by photovoltaic solar panels can have health effects.
The principle of photovoltaic solar energy production is that light energy is directly converted into electrical energy. The advantage is that solar power can be anywhere and can provide electricity nearby. The downside is that the price is still relatively expensive. . Photovoltaic power generation is a technology that uses the photovoltaic effect at the semiconductor interface to directly convert light energy into electrical energy. The key element of this technology is the solar cell. Solar cells can be packaged and protected after being connected in series to form a large area solar cell module. Flat solar cell modules are photovoltaic solar panelsues.
Solar energy refers to the energy of thermal radiation from the sun (see the three modes of propagation of thermal energy: radiation). Its main manifestation is often called solar rays. Nowadays, it is typically used to generate electricity or provide energy for water heaters.
