Solar photovoltaic power generation is a technology that uses solar energy to directly convert light energy into electrical energy. Photovoltaic power generation systems are mainly composed of photovoltaic cells. When sunlight shines on the photovoltaic cells, photons interact with atoms in the semiconductor material to produce a photoelectric effect, causing electrons to jump from the valence band to the conduction band and form an electric current. In this way, photovoltaic cells can be formed by connecting photovoltaic cells in series and parallel, which can be used to directly supply power or store electrical energy.
The advantages of solar photovoltaic power generation are as follows:
Renewable resources: Solar energy is a renewable energy source with wide distribution and abundant resources.
Environmentally friendly and clean: Solar photovoltaic power generation does not produce pollutants such as carbon dioxide, nitrogen oxides, etc. It is environmentally friendly and can effectively reduce greenhouse gas emissions and air pollution.
Low maintenance costs: Solar photovoltaic systems generally have a long lifespan and relatively low maintenance costs.
Distributed power generation: Solar photovoltaic power generation can be distributed in various places, reducing power transmission losses and pressure on the power grid.
Diversified applications: Solar photovoltaic power generation can be widely used in various fields such as homes, commerce, and industry, and can be constructed on a large scale according to needs.
