What are the benefits for industrial and commercial users to install photovoltaic power generation systems?

The benefits of installing photovoltaic power generation systems for industrial and commercial users are: large industrial and commercial electricity consumption, high electricity prices, a large proportion of self-generation and self-use, short payback period, and high rate of return; in addition, photovoltaic systems have the social benefits of energy conservation and emission reduction, which can help industrial users achieve energy conservation and emission reduction targets, while reducing the electricity costs of enterprises and improving their competitiveness.

What electrical safety requirements should be taken into consideration during the installation of photovoltaic modules? Will leakage pose a danger to human life?

As long as there is sunlight, the photovoltaic modules will have electricity, so the power supply cannot be cut off when there is sunlight, and due to the accumulation of series voltage, the corresponding voltage to the ground will also be very high. Therefore, the installation process should strictly comply with the installation and use instructions provided by the system supplier and be completed by professional installers. The wiring part of the equipment is installed using professional connectors with a protection level of IP65. The electrical equipment is also protected by air switches to prevent leakage current from causing harm to life.

Will solar power generation cause power shortage in winter?

The power generation of photovoltaic power generation system is very little affected by temperature. The factors that directly affect the power generation are the radiation intensity and sunshine duration. In winter, the radiation intensity will inevitably be weak and the sunshine duration will be short, so the power generation will be less than in summer, which is also a very normal phenomenon. The system is a grid-connected system. As long as there is electricity in the grid, the household load will not experience power shortage or power outage.

What issues should be paid attention to when selecting solar photovoltaic brackets

Anti-corrosion performance is also an important parameter of photovoltaic brackets, because the quality of anti-corrosion not only affects the service life of photovoltaic power stations, but also affects the appearance of brackets. Usually, the surface of steel brackets is treated with hot-dip galvanizing, which is generally required to be above 65μ. Under normal circumstances, it can ensure a service life of 20 years, but regular maintenance is required. The surface of aluminum alloy brackets is anodized to form a dense oxide film, and the anti-corrosion performance is far better than that of steel brackets.

What are the characteristics of photovoltaic module failure?

Common aging phenomena of crystalline silicon modules include cell fragmentation, hot spots, EVA yellowing, backplane cracking, snail lines, etc., which are visible to the naked eye. Although hot spots, junction box cold soldering, diode failure, and electrothermal induced attenuation are not visible to the naked eye, they will cause serious uneven heating of the cells inside the module and a significant decrease in power generation, which can be detected by technical means.

What are the ten major factors that affect the power generation of solar photovoltaic power stations?

When the actual installed capacity of a photovoltaic power station is constant, the power generation of the photovoltaic system is determined by the intensity of solar radiation, and there is a positive correlation between solar radiation and power generation. The intensity and spectrum characteristics of solar radiation change with meteorological conditions. So, what are the factors that affect the power generation of solar photovoltaic power stations?
