Explanation:
Photovoltaic power generation system is a power generation system that directly converts solar energy into electric energy by using solar cells. Its main components are solar cells, storage batteries, controllers and inverters. Its characteristics are high reliability, long service life, no environmental pollution, independent power generation and grid-connected operation, which are favored by enterprises and organizations in various countries and have broad development prospects.
Technical background:
It is predicted that solar photovoltaic power generation will occupy an important position in world energy consumption in 2 1 century, which will not only replace some conventional energy sources, but also become the main body of world energy supply. It is estimated that by 2030, the proportion of renewable energy in the total energy structure will exceed 30%, and the proportion of solar photovoltaic power generation in the world's total power supply will exceed10%; By 2040, renewable energy will account for more than 50% of the total energy consumption, and solar photovoltaic power generation will account for more than 20% of the total electricity; By the end of 2 1 century, renewable energy will account for more than 80% of the energy structure, and solar power generation will account for more than 60%. These figures are enough to illustrate the development prospect of solar photovoltaic industry and its important strategic position in the energy field.
System form:
There are three main types: 1. Independent photovoltaic power generation system (off-grid system) II. Grid-connected photovoltaic power generation system 3. Distributed photovoltaic power generation system
