Photovoltaic power plant refers to a photovoltaic power generation system that utilizes the sun's energy, adopts special materials such as crystalline silicon panels, inverters and other electronic components, connects to the power grid and delivers electricity to the grid, photovoltaic power plant EPC is photovoltaic general contracting.The application of the EPC general contracting mode in the construction of photovoltaic power plants is mainly the contracting mode of designing, purchasing and constructing specific construction of photovoltaic power plant construction projects. The construction mode is characterized by fast construction speed and high degree of integration, which is conducive to the project owner's control of the construction period, control of risks, and improvement of quality.In 2021, China's PV power plant EPC services market size reached 215.7 billion yuan, an increase of 32.8 billion yuan compared with 2020, and it is expected that China's PV power plant EPC services market size will reach 312.3 billion yuan in 2022, an increase of 96.6 billion yuan compared with 2021. 96.6 billion yuan. China as the new photovoltaic installed capacity of the largest countries, photovoltaic EPC business market size is huge, and domestic enterprises with the technology, experience, talent and other aspects of the continuous accumulation of international competitiveness is rapidly improving, and gradually enter the overseas photovoltaic EPC market. In the long run, photovoltaic power plant EPC industry is still an emerging industry, is currently in the growth period, the future prospects are broad.
