What are the dangers of photovoltaic energy production? The latest relevant information

No harm done.

1.

The production of photovoltaic solar energy produces no waste gas, no waste water, no waste residues or any other waste.

2. There are no rotating parts during operation and no noise pollution will be produced.

3. The principle of photovoltaic energy production is the photovoltaic effect. Solar cell components generate direct current under light conditions, after a certain series and parallel connection, they are connected to the grid-connected inverter and converted to direct current. 50Hz AC230V/400V power supply, there is no high frequency alternating current, no electromagnetic radiation, and no harm to the human body during the whole production process and energy conversion.

4. The installation of the solar power plant cables uses the original pipes and bridges. Usually no extra linesis not laid, even if line laying is involved, it is done in a hidden structure and does not. damage the building and the original environment.

Photovoltaic power generation is currently one of the cleanest and most efficient sources of energy. This is a technology that uses the photovoltaic effect at the semiconductor interface to directly convert light energy into electrical energy. Photovoltaic power generation replaces coal-fired thermal power generation, reduces carbon dioxide emissions and helps curb global warming. But some say that the current solar photovoltaic industry cannot be defined in terms of green environmental protection, and the pollution caused by its rapid development cannot be ignored by us in various "ways". In fact, there is no smoke without fire.There is indeedThere is a side of environmental pollution behind the photovoltaic industry.

Construction period of photovoltaic power plants:

Large-scale photovoltaic power plants are generally far from residential areas. The construction process mainly includes pile pressing, photovoltaic panel installation, cable laying, etc. The main environmental impacts are noise, dust, sewage and soil, etc. As long as the construction process and post-construction process are managed properly, the impact on the environment will be minimal.

Operation period of the photovoltaic plant:

Photovoltaics is a device that converts solar energy into light energy. It does not produce waste water or gas during use. However, inverters, box type transformers and other equipment will produce anoise during operation, which is 65-75 dB, which is equivalent to the sound of loud singing at home. However, in the process of installing equipment and facilities, low-noise equipment is usually selected and some basic vibration reduction treatments are carried out. In addition, photovoltaics are generally installed in non-residential areas and have less impact on the environment.

Photovoltaic pollution does not mainly concern the electricity production process, but mainly the photovoltaic material production process. During the production process of high-purity polysilicon, the raw material for photovoltaic modules, certain by-products will be produced. For example: the production of high purity polysilicon mainly uses the modified Siemens method. This production method will convert metallurgical grade silicon into trich siliconhelium loride, which can be reduced to solar-grade polysilicon by adding hydrogen. silicon chloride will form. When silicon chloride encounters humid air, it will break down into silicic acid and chlorine. Hydrogen will cause pollution problems if not managed properly. While developing photovoltaic energy production as much as possible, we must also do our best to minimize its damage to the environment and its impact on the lives of local residents.

At present, the advantages of photovoltaic power generation must outweigh the disadvantages. Therefore, when applying photovoltaic power generation, the performance ratio of photovoltaic power generation should be considered. For the long-term operation of solar power plants, the performance ratio is determined by four main parameters: irradiancesolar energy, battery backplane temperature, dust and dirt, and power generation. Among them, dust contamination on the glass of photovoltaic modules is one of the main problems that quickly affects the performance rate of photovoltaic power plants. This reduces power generation efficiency and performance ratio (PR) and increases cleaning costs. Dust and dirt containing oxides will also increase the failure rate of photovoltaic cells, affect the safety of use, and shorten the service life of solar cells. The Dust Index Monitoring System is an intelligent indicator device for the cleanliness of photovoltaic modules based on silicon-based radiation sensors. It uses the response characteristics of silicon-based radiation sensors to radiation intensity under different pr conditions.clean and cooperates with intelligent data collection equipment to achieve automated and continuous monitoring of the cleanliness of photovoltaic modules. By measuring and calculating the SR value of dust, investors can balance power generation efficiency with cleaning costs. Power plant operation and maintenance personnel no longer need to conduct visual inspections through experience and can scientifically choose a good cleaning solution, thereby avoiding. losses in power generation efficiency and wasted cleaning costs, thereby increasing the revenue of the power plant.
