Photovoltaic brackets are the vital backbone of solar panel installations, providing essential support and fixings for these energy-harnessing panels. Their primary mission is to position the panels for optimal sun exposure, thereby maximizing sunlight absorption and dramatically enhancing the efficiency of power generation systems. These brackets ensure your solar panels are always perfectly aligned to soak up the sun's rays.
Typically, these photovoltaic brackets are constructed from high-strength steel, serving as the indispensable 'skeleton' of solar systems. This steel undergoes advanced surface treatments—such as hot-dip galvanizing and galvanized aluminum magnesium processes—to significantly boost their resistance to corrosion, ensuring increased durability and a longer lifespan. Specifically:
Hot dip galvanized brackets: These are the stalwarts of the photovoltaic world, often featuring a thickness greater than 2mm, and in areas with strong winds, they can reach up to 2.5mm. Although the initial investment is higher, their long lifespan, robust strength, and outstanding stability offer excellent value and performance.
• Galvanized aluminum magnesium support: Known for self-healing cuts, this metal surface resists challenges from chlorine, alkali, abrasion, and corrosion. It thrives in harsh environments like deserts, mudflats, and saline-alkaline lands. This superior quality option is also cost-effective, reducing operational expenses while enhancing the safety and reliability of your power station.
Aside from steel, the market also offers aluminum alloy photovoltaic brackets. These brackets are remarkably lightweight, approximately a third of the weight of their steel counterparts. While they may lack the same strength and toughness and are more costly, their exceptional corrosion resistance makes them ideal for photovoltaic systems in coastal regions and on color steel roofs, where preventing rust is crucial.
Photovoltaic brackets boast diverse designs, categorized by installation methods into fixed and tracking brackets. Fixed brackets have a static orientation but allow manual adjustments to align with seasonal lighting changes. In contrast, tracking brackets autonomously follow the sun's path, ensuring your panels continually face the sun, albeit at a higher cost.
Furthermore, based on specific application scenarios, photovoltaic brackets are classified into roof, ground, and agricultural photovoltaic system brackets, among others. Each type is meticulously engineered to meet the unique demands of different environments, ensuring stable and efficient electricity generation from photovoltaic panels.
In the realm of photovoltaic manufacturing, raw materials dominate the cost structure, representing over 70% of total expenses, with steel constituting half of this portion. Bracket weight varies depending on the material, design, and scale, influencing cost and performance.
The application spectrum for photovoltaic brackets is vast, extending from expansive ground-based power stations to residential rooftop systems and agricultural photovoltaic setups. These brackets are indispensable, forming the backbone of the photovoltaic power generation ecosystem, ensuring stability and efficiency across the entire system.
