Photovoltaic power generation equipment has been running in the outdoor environment for a long time, and the erosion of light, rain, wind and sand will accelerate the aging of cables and connectors, resulting in the decline of equipment insulation performance, causing equipment failure and even causing fire.

Therefore, it is necessary to regularly test the electrical wiring and power generation equipment of the photovoltaic system, and carry out necessary repairs or replacement of aging cables and equipment to ensure the safe operation of the system and reduce the risk of fire.

Hidden faults in power station equipment.

Photovoltaic modules. Irregular operation during transportation and installation will cause internal cracks, and the blocking of trees, weeds or bird droppings will cause the module to form hot spots, which will not only affect the output performance of the module, but also lead to fire accidents in serious cases.

Since these hidden faults cannot be directly detected with the naked eye, it is necessary to use professional instruments to regularly test the components to eliminate hidden faults in time and prevent the occurrence of safety accidents.

Risk of grounding failure.

As with all electrical equipment, PV modules and mounting systems must be grounded to reduce potential electric shock and fire threats. If the performance of the grounding system degrades over time, it increases the likelihood that the person involved will approach and come into contact with the metal parts of the PV system and receive an electric shock.

Once an electric shock occurs, the damage caused can be very serious due to the high voltage of the PV array. Therefore, it is necessary to carry out regular grounding performance testing and maintenance to effectively prevent the degradation of grounding performance.

Due to the photovoltaic power station.

The short construction period and the poor technical level of construction personnel and operation and maintenance personnel lead to inadequate equipment installation, non-standard maintenance operations, and even hidden faults of equipment (such as hidden cracks and hot spots of components), which bring certain hidden dangers to the safe and stable operation of the power station. Therefore, after the photovoltaic power station is put into operation, it is necessary to regularly test the performance of the equipment to eliminate these hidden dangers and ensure the stable operation of the power station.

There is no harm. The principle of photovoltaic power generation is a purely physical effect, which converts the light irradiated on the panels into electricity, and does not convert it through your body, how can it harm the human body, and the place where your roof is covered can also be protected from the sun and wind.

Introduction to photovoltaic power generation:

Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photogenerated volt effect at the semiconductor interface.

It is mainly composed of three parts: solar panels (components), controllers and inverters, and the main components are composed of electronic components.

Solar cells can be encapsulated and protected in series to form large-area solar cell modules, and then combined with power controllers and other components to form photovoltaic power generation devices.

Fire risk Photovoltaic power generation equipment is operated in an outdoor environment for a long time, and the erosion of light, rain, wind and sand will accelerate the aging of cables and connectors, resulting in the decline of equipment insulation performance, resulting in equipment failure and even fire.

Hello, dear, I am happy to answer for you: The hazards of solar photovoltaic power generation are mainly as follows: 1. Environmental pollution

Photovoltaic power generation requires a large number of minerals, such as tin, lead, lead and zinc, etc., as well as a large number of organic solvents, acid and alkali detergents, etc., resulting in environmental pollution. 2. Seriously affect plants: photovoltaic power generation facilities will block sunlight, affect the growth of plants, and cause plant death.

3. Soil drying: Photovoltaic power generation facilities will cover a large area of land, which will cause the soil to be damaged and dry, making the soil become unvibrant. 4. Water pollution:

Photovoltaic power plants need a lot of water to cool, and if the water quality is not good, water pollution will occur. 5. Electromagnetic radiation: The high-voltage Sunying line of the photovoltaic power plant will emit electromagnetic radiation, which is harmful to the body.

6. Noise pollution: The noise of photovoltaic power generation facilities will have an impact on the surrounding environment, resulting in noise pollution.

Photovoltaic power generation is not harmful to the human body.

1. The photovoltaic power generation system converts solar energy into electrical energy according to the principle of light voltaic effect, no pollution, no radiation, and electronic devices such as inverters and distribution cabinets have passed the EMC (electromagnetic compatibility) test, so there is no harm to the human body. In addition, solar photovoltaic power generation does not produce any waste such as exhaust gas, waste water, waste residue, etc. There are no rotating parts during operation and no noise pollution is generated.

The principle of photovoltaic power generation is the photogenerated voltaic effect, the solar cell module generates direct current under the condition of light, and after a certain series and parallel summary, it is connected to the grid-connected inverter and converted into a 50Hz AC230V 400V power supply, without any high-frequency alternating current and electromagnetic radiation in the whole power generation and conversion process, and will not cause harm to the human body.

4. The cable laying of the solar power station adopts the original pipeline and bridge, and generally does not lay additional lines, even if it involves the laying of the line, it is also a hidden structure that does not damage the original building and environment.

2. The photovoltaic power generation system converts solar energy into electrical energy, which will not produce dry sound effects, and the noise index of the inverter is not higher than 65 decibels, and there will be no noise hazards.
