Photovoltaic brackets play a crucial role in solar power generation systems. These components are meticulously engineered to support, install, and secure solar panels, ensuring optimal performance.
1, Classification
Photovoltaic brackets come in various types, tailored to diverse application environments and installation needs:
1. Fixed bracket: Known for its robust stability, this bracket type is ideal for locations where frequent adjustments aren't necessary. Once set, it typically remains static. Its design takes into account several factors like geographical location, surrounding environment, and climate. Depending on the application, fixed brackets can be categorized 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: Resembling the fixed bracket but equipped with an adjustable mechanism, this bracket allows the manual adjustment of the tilt angle. By modifying the tilt angle in line with seasonal or periodic changes, the solar incidence angle can be optimized, resulting in enhanced direct sunlight absorption and improved power generation efficiency of photovoltaic modules.
3. Automatic tracking bracket: Utilizing an intelligent control system, these brackets provide all-weather automatic sun tracking, thereby maximizing solar energy utilization. Tracking brackets are categorized into flat single axis, oblique single axis, and dual axis tracking brackets. Such systems automatically adjust component orientations based on lighting conditions, thereby minimizing the angle between the components and direct sunlight. This system can significantly augment power generation by 10% to 25% or even more.
4. Flexible bracket: This large-span structure, supported by fixed ends, features a prestressed flexible cable at its core. The structural system encompasses several key components including the cable structure, support system, damping system, and anchor system. Designed for high clearance and minimal pile foundations, flexible supports are especially effective in expansive applications such as mountainous terrains, barren slopes, water pools, fishing ponds, and forests.
2, Component Parts
The primary components of a photovoltaic bracket include:
1. Column: Provides foundational support and is typically anchored to the base.
2. Beam: Connects the columns, providing a support framework for photovoltaic modules.
3. Slant support: Enhances stability by preventing tilting and deformation, ensuring the structure's durability.
4. Connectors: Comprising bolts, nuts, etc., these components secure various parts of the bracket together.
3, Functional Features
1. Support and fixation: Secures photovoltaic modules, safeguarding against external forces like wind and snow.
2. Optimize orientation and tilt angle: Adjusts component orientation and tilt for maximum solar exposure.
3. Extend system lifespan: Thoughtful design reduces wear and damage, extending component longevity.
4. Adapt to various environments: Versatile solutions are available for installation on rooftops, floors, or water surfaces.
4, Material selection
When selecting materials for photovoltaic brackets, consider factors such as weather resistance, load-bearing capacity, corrosion resistance, and cost-effectiveness. Popular materials include hot-dip galvanized steel, aluminum alloy, and stainless steel.
