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.

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.

What are the usage scenarios/application areas of photovoltaic tiles?

Photovoltaic tiles integrate solar power generation products into buildings, so they have the dual characteristics of building materials and power generation. It gives traditional building materials the ability to generate electricity, allowing buildings to generate electricity. Photovoltaic tiles have a variety of power generation application scenarios and are widely used in industrial and commercial roofs, tourist landscapes, antique buildings, awnings, parking sheds and other fields.

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 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.
