Solar photovoltaic (PV) power generation is a process that utilizes solar energy to convert light energy into electricity. It is based on the photovoltaic effect, by using photovoltaic cells or photovoltaic modules to convert sunlight into direct current (DC), which is then converted into alternating current (AC) by an inverter and supplied to the power system or used for direct power supply.
Among them, photovoltaic cells are the core component of solar photovoltaic power generation and are usually made of semiconductor materials (e.g. silicon). When sunlight strikes a PV cell, photon energy excites electrons in the semiconductor material, generating an electric current. This current passes through a circuit connected to the PV cell and can be used for power or storage.
Currently because the cost of solar photovoltaic technology continues to fall, especially the price of photovoltaic modules. This has reduced the investment cost of solar power systems, making solar an increasingly competitive energy option.
Many countries and regions have introduced policy measures and targets to promote the development of solar PV. Measures such as renewable energy standards, subsidy programs, and tax incentives are driving the growth of the solar market.
China is the largest solar PV market in the world and has the largest installed PV capacity in the world. Other market leaders include the U.S., India, and European countries.
The solar PV market is expected to continue to grow in the future. With further cost reductions, technological advances and strengthened policy support, solar PV will play an increasingly important role in the global energy supply.
The combination of solar PV with energy storage technologies, smart grids and other forms of renewable energy will provide more integrated solutions for realizing a sustainable energy future.
