Photovoltaic brackets are essential components in photovoltaic power generation systems, meticulously crafted to support, install, and firmly secure solar panels. These brackets serve as the backbone of solar installations, ensuring stability and efficiency.
1, Classification
Tailored to diverse application environments and installation needs, photovoltaic brackets are skillfully classified into various types:
1. Fixed bracket: Known for its robust stability, this bracket is ideal for applications that do not necessitate frequent adjustments. Once positioned, it remains steadfast, with its design accommodating a multitude of factors such as geographical location, environmental conditions, and climate. Based on usage scenarios, fixed photovoltaic brackets are subdivided into roof types (including color steel plate roofs, sloping roofs, flat roofs, etc.), ground types (single column, double column, etc.), and water surface types (floating, column, etc.).
2. Adjustable tilt bracket: Sharing structural similarities with fixed brackets, this variant boasts an additional adjustment mechanism allowing manual tilt angle flexibility. By periodically adjusting the bracket's tilt, the solar incidence angle can be optimized in line with seasonal or periodic shifts, thereby boosting direct sunlight absorption and enhancing the power generation efficacy of photovoltaic modules.
3. Automatic tracking bracket: This innovative bracket harnesses an intelligent control system to achieve all-weather, automatic solar tracking, thereby maximizing solar energy utilization. Tracking brackets are categorized into flat single axis tracking brackets, oblique single axis tracking brackets, and dual axis tracking brackets. The photovoltaic power generation system utilizing such tracking brackets can seamlessly adjust component orientation according to lighting conditions, minimizing the angle discrepancy between components and direct sunlight. This typically results in a significant increase in power generation efficiency by 10% to 25% or even greater.
4. Flexible bracket: Featuring a large-span photovoltaic module support structure with fixed ends, this bracket's core is a prestressed flexible cable system. This structural marvel encompasses key elements such as cable system, support system, damping mechanism, and anchor system. The flexible support design elevates photovoltaic modules above the ground to a certain height, offering the benefit of high clearance while reducing pile foundation requirements. It is especially advantageous for extensive application scenarios like ordinary mountains, barren slopes, water pools, fishing ponds, and forests.
2, Component Parts
The photovoltaic bracket is primarily composed of several vital components:
1. Column: Acts as the cornerstone, supporting the entire system and typically anchored to the foundation.
2. Beam: Serves as the connecting element between columns, supporting the photovoltaic modules with precision and strength.
3. Slant support: Reinforces the structure's stability, mitigating risks of tilting and deformation.
4. Connectors: Comprising bolts, nuts, and other fasteners, these ensure the secure assembly of the bracket components.
3, Functional Features
1. Support and fixation: Guarantees the steadfast installation of photovoltaic modules, adeptly resisting external forces such as wind and snow.
2. Optimize orientation and tilt angle: Skillfully adjusts component orientation and tilt angle to maximize solar radiation capture and efficiency.
3. Extend system lifespan: Through meticulous design, it reduces component wear and potential damage, prolonging system durability.
4. Adapt to various environments: Whether on rooftops, grounds, or water surfaces, there exists a suitable photovoltaic bracket solution for every scenario.
4, Material selection
In selecting materials for photovoltaic brackets, considerations include weather resistance, load-bearing capacity, corrosion resistance, and cost-effectiveness. Popular choices encompass hot-dip galvanized steel, aluminum alloy, and stainless steel, each offering distinct advantages for varying requirements.
