Photovoltaic brackets play a pivotal role in the realm of solar energy systems, serving as the essential framework that supports and secures solar panels. By positioning photovoltaic panels at the ideal angle towards the sun, these brackets maximize sunlight absorption, thereby significantly boosting the panels' power generation efficiency.
The backbone of photovoltaic brackets is typically constructed from steel, often referred to as the 'skeleton' of these structures. These steel components undergo advanced surface treatments, such as hot-dip galvanizing and galvanized aluminum magnesium coating, to greatly enhance their resistance to corrosion and extend their lifespan. Specifically:
Hot dip galvanized brackets: A prevalent choice in the industry, characterized by a thickness usually exceeding 2mm, and potentially reaching 2.5mm in areas prone to strong winds. Although it involves a higher cost, this option offers exceptional longevity, superior strength, and remarkable stability.
• Galvanized aluminum magnesium supports: Notable for their self-healing cuts, these supports boast a metal surface that resists chlorine, alkali, abrasion, and corrosion. They are adept at withstanding challenging environments such as deserts, mudflats, and saline-alkaline lands, delivering excellent quality at a cost-effective price, thereby enhancing the safety and cost-efficiency of power stations.
Beyond steel, aluminum alloy has emerged as a popular material for photovoltaic brackets. These brackets are significantly lighter, weighing merely a third of their steel counterparts, yet they sacrifice some strength and toughness for this advantage. More expensive, they offer outstanding corrosion resistance and are ideal for installations in coastal areas or atop color steel roofs, where rust prevention is crucial.
Photovoltaic brackets are available in various types tailored to installation methods: fixed and tracking brackets. Fixed brackets maintain a static component orientation, adjustable manually to accommodate seasonal lighting changes. In contrast, tracking brackets dynamically follow the sun's path, ensuring optimal panel orientation, albeit at a higher cost.
Furthermore, tailored to different scenarios, photovoltaic brackets diversify into categories such as roof brackets, ground brackets, and agricultural photovoltaic system brackets. Each is meticulously engineered to cater to unique environments and requirements, guaranteeing that solar panels can generate electricity consistently and effectively.
In the cost matrix of manufacturing photovoltaic brackets, raw materials dominate with over 70% of the total, half attributed to steel. Variations in bracket weight stem from differences in materials, design intricacies, and project scale.
The application spectrum of photovoltaic brackets is vast, ranging from expansive ground-based solar farms to residential rooftop systems and agricultural photovoltaic installations. Serving as the linchpin of solar power setups, they are crucial, underpinning the stability and efficiency of the entire energy generation process.
