How often do components need to be cleaned? What should be paid attention to during cleaning?

According to the product supplier's instructions, maintain the parts that need to be checked regularly. The main maintenance work of the system is to wipe the components. In areas with heavy rain, manual wiping is generally not required, and cleaning is done about once a month in the non-rainy season. The number of wiping can be increased as appropriate in areas with heavy dustfall. Areas with heavy snowfall should clear heavy snow in time to avoid affecting power generation and uneven occlusion caused by snowmelt, and the number of shielding components or debris should be cleaned in time.

Will the shadow of houses, leaves or even bird droppings on photovoltaic modules affect the power generation system?

Shadows on the components of the photovoltaic power generation system and obstructions caused by bird droppings will have a relatively large impact on the power generation system. The electrical characteristics of the solar cells used in each component are basically the same. Otherwise, the so-called hot spot effect will occur on the cells with poor electrical performance or being obscured. The obscured solar cell components in a series connection will be treated as loads to consume the energy generated by other illuminated solar cell components. The obscured solar cell components will generate heat at this time. This is the thermal effect phenomenon.

What occasions are distributed solar power generation systems suitable for?

Distributed photovoltaic power generation refers specifically to photovoltaic power generation facilities that are built near user sites, with the operating mode of self-generation and self-use on the user side, excess electricity connected to the grid, and balanced regulation in the distribution system. Distributed photovoltaic power generation uses photovoltaic modules to directly convert solar energy into electrical energy. It is a new type of power generation and comprehensive energy utilization method with broad development prospects. It advocates the principle of nearby power generation, nearby grid connection, nearby conversion, and nearby use.

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.
