Solar panels convert light energy into electrical energy.
Sunlight irradiates the solar cell to produce a photovoltaic voltage, which is the photovoltaic effect. If a load is connected to both ends of the solar cell at this time, a photo-generated current will be generated, and thus electrical energy will be generated. Solar power is called photovoltaic power generation.
Solar photovoltaic power generation system is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy.
Independent photovoltaic lighting systems generally use batteries as energy storage devices, which store the electrical energy output by the solar cells during the day and supply power to the lighting load at night.
