Photovoltaic brackets serve as the backbone of solar power generation systems, meticulously crafted to support, mount, and secure solar panels with precision and reliability.
1, Classification
Photovoltaic brackets can be classified into diverse types, tailored to meet specific application environments and installation criteria:
1. Fixed bracket: Renowned for its robust stability, this bracket is ideal for installations that demand minimal adjustments. Once positioned, it typically remains unaltered, with its design meticulously factoring in geographical nuances, environmental surroundings, and climatic conditions. Depending on the usage context, fixed photovoltaic brackets are further categorized into roof types (including color steel plate roofs, sloping roofs, flat roofs), ground types (single column, double column), and water surface types (floating, column).
2. Adjustable tilt bracket: Mirroring the structure of a fixed bracket, this variant introduces an additional adjustable mechanism, enabling manual modifications to the tilt angle. By periodically altering the bracket's tilt, it aligns with seasonal or cyclical shifts, thereby boosting the absorption of direct solar rays and enhancing the photovoltaic modules' energy production efficiency.
3. Automatic tracking bracket: Featuring an intelligent control system, this bracket offers seamless, round-the-clock sun tracking, optimizing solar energy harnessing. Tracking brackets are categorized into flat single axis, oblique single axis, and dual axis types. Such a system dynamically orients its components based on sunlight conditions, minimizing the angle between the modules and direct sunlight, leading to a remarkable energy yield increase ranging from 10% to 25% or more.
4. Flexible bracket: This expansive photovoltaic module support structure, with fixed ends, centers around a prestressed flexible cable design. It encompasses critical components like the cable structure, support system, damping system, and anchor system. The flexible design elevates photovoltaic modules to a certain height above the ground, offering high clearance benefits and reducing the necessity for numerous pile foundations. Particularly well-suited for vast application settings such as mountainous terrains, barren slopes, water pools, fishing ponds, and forested areas.
2, Component Parts
The photovoltaic bracket is comprised of essential components, including:
1. Column: This element bears the entire support system, typically anchored firmly on the foundation.
2. Beam: Acts as the connecting bridge between columns, providing robust support to photovoltaic modules.
3. Slant support: Bolsters the support’s stability, preventing any potential tilting or deformation.
4. Connectors: Featuring bolts, nuts, and more, these components ensure the secure assembly of the bracket's various parts.
3, Functional Features
1. Support and fixation: Guarantees the secure installation of photovoltaic modules, standing resilient against external forces like wind and snow.
2. Optimize orientation and tilt angle: Adjusts module orientation and tilt to maximize the reception of solar radiation.
3. Extend system lifespan: Through thoughtful design, it minimizes component wear and potential damage.
4. Adapt to various environments: Whether on rooftops, floors, or water surfaces, there are tailored photovoltaic bracket solutions available.
4, Material selection
Selecting materials for photovoltaic brackets involves assessing factors such as weather resistance, load capacity, corrosion resistance, and cost-effectiveness. Popular choices include hot-dip galvanized steel, aluminum alloy, and stainless steel.
