Photovoltaic equipment fixed magnets are special magnetic fixing components developed for photovoltaic power generation systems, solar panel support equipment, photovoltaic tracking brackets and photovoltaic module auxiliary equipment. Adopting high weather resistance, high stability neodymium iron boron and ferrite composite magnetic materials, these magnets have excellent outdoor anti-aging, anti-corrosion and anti-demagnetization performance, and are mainly used for fixed installation, positioning limit, auxiliary locking and structural stabilization of photovoltaic modules and supporting equipment. With the rapid development of the global new energy photovoltaic industry, the large-scale construction of ground photovoltaic power stations, distributed rooftop photovoltaics and agricultural and photovoltaic complementary power stations has put forward higher requirements for the stability and durability of photovoltaic equipment fixing parts, making photovoltaic special fixed magnets an important auxiliary accessory in the photovoltaic industry chain.

In terms of material performance adaptation, photovoltaic equipment fixed magnets are designed for long-term outdoor working environment, mainly adopting high-temperature resistant and weather-resistant N35M, N38M, N40M series NdFeB magnets and high-performance ferrite magnets. The products have strong environmental adaptability, can work stably for a long time in the outdoor environment of -40℃ to 85℃, resist strong ultraviolet radiation, wind and rain erosion, high temperature exposure and low-temperature freezing, and will not have magnetic attenuation, coating peeling or structural damage. Through special outdoor aging test certification, the magnetic performance attenuation rate of the product is less than 0.5% every year, which can ensure more than 25 years of stable service, fully matching the service life of photovoltaic power generation equipment.

In terms of structural and process design, photovoltaic fixed magnets are mostly customized into square block, strip, cylindrical and special-shaped fixed magnetic blocks, which are convenient for embedded installation and bolt fixing of photovoltaic brackets and modules. The surface adopts multi-layer composite anti-corrosion treatment process of zinc plating + nickel plating + epoxy resin thick coating, with ultra-strong anti-rust, anti-oxidation and anti-ultraviolet ability, which can effectively resist the erosion of rainwater, snow water, acid and alkali fog in outdoor power station environment. The product has moderate magnetic adsorption force, which can firmly fix photovoltaic auxiliary parts, cable fixing parts and small structural parts, and will not cause structural damage to photovoltaic modules due to excessive magnetic force. At the same time, the magnet has good shock resistance, which can resist the vibration and impact of photovoltaic equipment caused by outdoor strong wind, ensuring the long-term stable fixing effect.

The application fields of photovoltaic equipment fixed magnets cover all links of photovoltaic power generation systems. First, in photovoltaic module fixing, it is used for auxiliary positioning and anti-shaking fixing of solar panels, assisting the bracket to fix the modules tightly, avoiding module displacement and shaking caused by outdoor wind force, and ensuring the stable power generation state of photovoltaic panels. Second, in photovoltaic tracking bracket equipment, the fixed magnets are matched with sensors and limit devices to realize the positioning limit and angle locking of the automatic tracking bracket, ensuring that the bracket can accurately adjust the angle according to the sunlight direction, improving the light absorption efficiency of photovoltaic modules and increasing power generation. Third, in photovoltaic power station auxiliary facilities, it is used for fixing power cables, wiring harnesses, small monitoring equipment and cleaning auxiliary equipment, realizing neat and stable layout of power station lines and equipment, and reducing equipment failure rate caused by loose falling of parts.

The industry application value of photovoltaic equipment fixed magnets is extremely prominent. In terms of economic benefits, the stable fixing performance reduces the maintenance frequency and replacement cost of photovoltaic equipment, avoids power generation loss caused by equipment loose failure, and improves the overall power generation efficiency and economic benefits of photovoltaic power stations. In terms of environmental adaptability, the ultra-strong weather resistance enables the magnets to adapt to various complex outdoor environments such as desert, coastal, mountain and plain photovoltaic power stations, solving the problem of easy aging and failure of traditional metal fixing parts in outdoor environment. In terms of installation convenience, magnetic fixing is flexible and efficient, which simplifies the equipment installation process, shortens the construction cycle of photovoltaic power stations, and reduces the construction labor cost. With the continuous expansion of the global photovoltaic new energy market, photovoltaic equipment fixed magnets are developing towards higher weather resistance, longer service life and more diversified customization, and have become an indispensable supporting accessory for the healthy development of the photovoltaic industry.
