Photovoltaic brackets, the stalwart pillars of solar technology, serve as robust supports and fixtures for photovoltaic panels, commonly recognized as solar panels. Their paramount function lies in their ability to ensure these panels are perfectly angled towards the sun, thus maximizing sunlight absorption and dramatically enhancing the efficiency of power generation.
Typically crafted from resilient steel, photovoltaic brackets act as the indispensable 'skeleton' of solar systems. These steels are subjected to advanced surface treatments—like hot-dip galvanizing and galvanized aluminum magnesium—to significantly boost their resistance to corrosion, thereby extending their durability and longevity. Specifically:
Hot dip galvanized brackets: These brackets are highly prevalent and generally have a thickness that exceeds 2mm, reaching up to 2.5mm in areas with elevated wind conditions. Although their cost is relatively high, they offer an extended lifespan, remarkable strength, and outstanding stability.
• Galvanized aluminum magnesium support: This option boasts self-healing cuts and a metal surface that bravely withstands chlorine, alkali, abrasion, and corrosion. It is perfectly suited for the challenging environments of deserts, mudflats, and saline, alkaline lands. This choice is of superior quality and budget-friendly, reducing operational costs while enhancing the safety and reliability of the power station.
Besides steel, the market also offers aluminum alloy-based photovoltaic brackets. These brackets are significantly lightweight, only about a third of their steel counterparts, yet they possess lesser strength and toughness and come at a higher cost. However, their exceptional corrosion resistance positions them as the ideal choice for photovoltaic systems in coastal areas and on color steel roofs, where rust prevention is paramount.
Photovoltaic brackets are available in a variety of designs. Based on installation methods, they can be categorized into fixed and tracking brackets. Fixed brackets have components with a static orientation, allowing manual seasonal lighting adjustments. In contrast, tracking brackets can autonomously follow the sun's trajectory, keeping the photovoltaic panel perennially sun-facing, albeit at a higher price point.
Additionally, photovoltaic brackets can be classified according to distinct application scenarios into roof, ground, and agricultural photovoltaic system brackets, among others. Each design is meticulously engineered to meet specific environmental and operational needs, ensuring photovoltaic panels consistently generate electricity in a stable and efficient manner.
In the realm of photovoltaic bracket manufacturing, raw material costs are a significant factor, comprising over 70% of the overall expense, with steel alone accounting for half of this percentage. Variations in bracket weight are influenced by material choice, design intricacies, and the scale of the installation.
The application spectrum for photovoltaic brackets is vast, encompassing everything from expansive ground-based photovoltaic power stations to domestic rooftop systems and agricultural photovoltaic solutions. Their presence is vital, serving as a crucial component of the photovoltaic power generation ecosystem, supporting both the stability and efficiency of the entire power generation system.
