Through the solar cells (also known as photovoltaic cells) will be converted from solar radiation energy to electricity power generation system is called solar cell power generation system (also known as solar photovoltaic power generation system).
Solar photovoltaic power generation is currently widely used in the engineering of photoelectric conversion devices crystalline silicon solar cells, production technology is mature, has entered into large-scale industrial production, widely used in industry, agriculture, science and technology, culture and education, national defense and people's lives in various fields. It is expected that by the middle of the 21st century, solar photovoltaic power generation will develop into an important power generation method and take up a certain proportion of the world's sustainable energy structure.
The operation of ground solar photovoltaic power generation systems can be divided into two main categories: off-grid operation and networked operation. Solar photovoltaic power generation systems that are not connected to the public grid are called off-grid solar photovoltaic power generation systems, also known as stand-alone solar photovoltaic power generation systems
It is mainly used in areas without electricity far from the public grid and some special places, such as providing basic electricity for lighting, watching TV and listening to radio for farmers and fishermen in remote rural areas, pastoral areas, islands, plateaus and deserts that are difficult to be covered by the public grid, and providing power for special places such as communication relay stations, coastal and inland water beacons, oil and gas pipeline cathodic protection, weather stations, highway shifts and border guard posts. The solar photovoltaic power generation system connected to the public grid is called networked solar photovoltaic power generation system.
It is an important direction for solar photovoltaic power generation to enter the stage of large-scale commercial power generation and become one of the components of the power industry, and is the mainstream trend of the development of solar photovoltaic power generation technology in the world today.
