What is solar photovoltaic power generation?
Solar photovoltaic power generation mainly uses the photovoltaic effect to generate electricity by absorbing sunlight. The photovoltaic panel absorbs solar energy and converts it into direct current, and then converts it into usable alternating current through an inverter for home use.
At present, it is more common in China to have home rooftop photovoltaic power generation. Photovoltaic power station is installed on the roof, the electricity generated for household use, and the electricity not used up is connected to the national grid, in exchange for a certain amount of revenue. There is also a type of PV power plant for commercial and industrial rooftops as well as large ground power plants, both of which are practical life applications of PV power generation.
What are the types of photovoltaic power generation?
Solar photovoltaic systems are divided into off-grid photovoltaic systems, grid-connected photovoltaic systems and distributed photovoltaic systems:
Off-grid photovoltaic power generation system mainly consists of solar modules, controller, battery, and to supply power to AC loads, an AC inverter is also required.
Grid-connected photovoltaic power generation system is the direct current generated by the solar modules through the grid-connected inverter into AC power that meets the requirements of the utility grid, and then directly connected to the public grid. Grid-connected power generation systems are centralized large-scale grid-connected power stations are generally national power stations, the main feature is to transmit the generated energy directly to the grid, the grid unified deployment of power supply to users.
Distributed photovoltaic power generation system, also known as decentralized power generation or distributed energy supply, refers to the configuration of smaller photovoltaic power supply systems at or near the user site to meet the needs of specific users, to support the economic operation of the existing distribution grid, or to meet the requirements of both.
