Solar energy is an inexhaustible renewable energy source for human beings, with full cleanliness, absolute safety, relative extensiveness, true long life and maintenance-free, resource adequacy and potential economy, etc., and has an important position in long-term energy strategy. Among them, the use of renewable energy such as solar energy for photovoltaic power generation by industrial enterprises is an important part of achieving the strategic goals of “carbon peak” and “carbon neutrality”.

1.What is photovoltaic power generation?
Photovoltaic power generation is a technology that uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy, and the main principle is the photoelectric effect of semiconductors. It is composed of three parts: solar panel (component), controller and inverter, and the main components are composed of electronic components. After the solar cells are connected in series, they are packaged and protected to form a large-area solar cell module, and then combined with power controllers and other components to form a photovoltaic power generation device.

2.What is the position of photovoltaic power generation in achieving the strategic goals of “carbon peak” and “carbon neutrality”?
To achieve the strategic goals of “carbon peaking” and “carbon neutrality”, the proportion of zero-carbon energy is crucial, among which photovoltaics, a natural renewable electricity source, are an important part of zero-carbon energy. The characteristics of low construction cost, low maintenance cost, long service cycle, relaxed use conditions and wide range of use scenarios of photovoltaic power generation have also laid its pillar role as a new energy and zero-carbon energy in the process of achieving the goals of “carbon peak” and “carbon neutrality”. Especially with the improvement of manufacturing technology and the expansion of manufacturing scale, the cost of photovoltaic power generation has been lower than the cost of traditional fossil energy power generation.

3.What are the advantages of photovoltaic power generation?
Compared with commonly used thermal power generation systems, the advantages of photovoltaic power generation are mainly reflected in:
● No risk of depletion
● Safe and reliable, no noise, no pollution emission, absolutely clean (no pollution)
● It is not limited by the geographical distribution of resources, and the advantages of building roofing can be used; For example, areas without electricity, as well as areas with complex terrain
● No fuel consumption and transmission lines are required to generate power locally
● High energy quality
● The user is emotionally receptive
● The construction period is short and the time it takes to obtain energy is short
