Photovoltaic power generation is a technology that directly converts light energy into electric energy by using photovoltaic effect of semiconductor interface. It is mainly composed of solar panels (components), controllers and inverters, and the main components are composed of electronic components. After the solar cells are connected in series, they can be packaged and protected to form a large-area solar cell module, and then form a photovoltaic power generation device with power controllers and other components.
No matter from the world or from China, conventional energy is very limited. China's disposable energy reserves are far below the world average, accounting for only about 10% of the world's total reserves. Solar energy is an inexhaustible renewable energy source for human beings, which has the advantages of complete cleanliness, absolute safety, relative popularity, long service life, maintenance-free, abundant resources and potential economy, and occupies an important position in the long-term energy strategy.
Compared with the commonly used thermal power generation system, the advantages of photovoltaic power generation are mainly reflected in:
(1) there is no danger of failure;
(2) Safe and reliable, without noise and pollution discharge, absolutely clean (pollution-free);
(3) Not limited by the geographical distribution of resources, the advantages of building roofs can be utilized; For example, areas without electricity and areas with complex terrain;
(4) local power generation and power supply can be realized without consuming fuel and erecting transmission lines;
⑤ High energy quality;
⑥ Users are easy to accept emotionally;
⑦ The construction period is short, and the time required for obtaining energy is short.
