Photovoltaic brackets predominantly serve as robust supports and fixtures for photovoltaic panels, synonymous with solar panels. Their primary function is to ensure that these panels are optimally oriented towards the sun, thereby maximizing sunlight absorption and significantly boosting the efficiency of power generation.
Typically crafted from steel, photovoltaic brackets act as the essential 'skeleton' of the system. These steels undergo specialized surface treatments—such as hot-dip galvanizing and galvanized aluminum magnesium—to significantly augment their resistance to corrosion as well as extend their durability and longevity. Specifically:
Hot dip galvanized brackets: Highly prevalent, these brackets generally boast a thickness exceeding 2mm, reaching up to 2.5mm in areas with higher wind conditions. Though the cost is comparatively elevated, they exhibit an extended lifespan, remarkable strength, and excellent stability.
• Galvanized aluminum magnesium support: Featuring self-healing cuts, this metal surface withstands chlorine, alkali, abrasion, and corrosion, enabling it to endure the challenging environments of deserts, mudflats, saline, and alkaline lands. This option is of superior quality and budget-friendly, helping to reduce operational costs while enhancing the safety and reliability of the power station.
Besides steel, aluminum alloy-based photovoltaic brackets are also available in the market. These aluminum alloy brackets are notably lightweight, weighing only about a third of their steel counterparts, though they exhibit lesser strength and toughness and come at a higher cost. However, their exceptional corrosion resistance makes them ideal for photovoltaic systems situated in coastal areas and installed on color steel roofs, where rust prevention is critical.
Photovoltaic brackets come in various designs. Based on installation methods, they can be categorized into fixed brackets and tracking brackets. While the components of fixed brackets have a static orientation, they allow manual adjustments in accordance with seasonal lighting changes. On the other hand, tracking brackets can autonomously follow the sun's position, ensuring the photovoltaic panel consistently faces the sun, albeit at a higher price point.
Moreover, according to distinct application scenarios, photovoltaic brackets can be further classified into roof brackets, ground brackets, and agricultural photovoltaic system brackets, among others. Each is meticulously designed to address specific environments and requirements, ensuring photovoltaic panels generate electricity in a stable and efficient manner.
In the realm of photovoltaic bracket manufacturing costs, raw materials are a predominant factor, accounting for over 70% of the overall cost, with steel making up half of this percentage. Variations in bracket weight are influenced by factors such as material, design, and scale.
The application spectrum for photovoltaic brackets is extensive, ranging from vast ground-based photovoltaic power stations to domestic rooftop systems and agricultural photovoltaic systems. Their presence is vital; they are key to the photovoltaic power generation ecosystem, underpinning the stability and efficiency of the entire power generation system.
