What are the disadvantages of photovoltaic power generation?

The disadvantages of photovoltaic power generation are: there are potential safety hazards, noise and a certain amount of environmental pollutants in the process of photovoltaic cell manufacturing and recycling.

1, there is a potential safety hazard.

There are certain safety risks in the operation of photovoltaic power generation. For example, in the environment of high temperature or strong sunshine, the performance of photovoltaic panels may decline, and even lead to safety accidents such as fire. In addition, photovoltaic panels may also generate static electricity, which may lead to electric shock and other dangerous situations, so special care should be taken when using photovoltaic power generation equipment.

Step 2 make noise

Although photovoltaic power generation is a kind of clean energy, its inverter will produce certain noise when it is running, which will bring certain influence to the surrounding environment. Therefore, when choosing the location of photovoltaic power station, we should consider the surrounding environmental factors and stay away from residential areas, schools and other public places.

3. A certain amount of environmental pollutants will be produced during the manufacturing and recycling of photovoltaic cells.

Although photovoltaic power generation itself will not emit a lot of pollutants, it will produce a certain amount of environmental pollutants in the process of photovoltaic cell manufacturing and recycling. For example, in the manufacturing process of solar panels, some harmful substances such as cadmium, chromium and other metal elements are needed, which may cause environmental pollution in abandoned panels. Therefore, with the rapid development of photovoltaic power generation industry, it is necessary to strengthen relevant pollution prevention measures.

Advantages of photovoltaic power generation

1, sustainability. At the current rate of nuclear energy generated by the sun, the storage of hydrogen is enough to last for billions of years. In today's increasingly serious ecological pollution, solar energy resources are inexhaustible and are truly renewable and clean energy.

2. Flexible installation position. Photovoltaic power generation can be installed not only on the roof of residential facilities, but also in industrial-scale facilities, and electricity can be obtained through solar power generation to meet the electricity demand in buildings.

3. The construction period is short. Compared with clean energy sources such as wind turbines, the construction period of photovoltaic power plants is shorter, and the total construction period can be controlled within 6 months. In addition, the operating cost of photovoltaic projects is relatively low, and it can be profitable in a short time.
