Photovoltaic brackets are pivotal components in photovoltaic power generation systems, meticulously engineered to support, install, and secure solar panels with precision and reliability. These brackets ensure optimal alignment and stability for solar installations, making them indispensable for efficient energy conversion.
1, Classification
Based on varying application environments and installation prerequisites, photovoltaic brackets are ingeniously categorized into several distinct types:
1. Fixed bracket: Renowned for its robust stability, this bracket is ideal for installations that seldom require adjustment. Once positioned, it remains steadfast, with a design that carefully considers geographical positioning, environmental circumstances, and climatic conditions. Depending on the application scenario, fixed photovoltaic brackets are further classified into roof (including color steel plate roofs, sloping roofs, flat roofs, etc.), ground (single column, double column, etc.), and water surface types (floating, column, etc.).
2. Adjustable tilt bracket: Sharing a structural resemblance with fixed brackets but featuring an additional adjustment mechanism, this bracket allows manual adjustment of the tilt angle. By periodically modifying the tilt angle, the solar incidence angle can be optimized to augment the absorption of direct sunlight, thereby significantly enhancing the power generation efficiency of photovoltaic modules.
3. Automatic tracking bracket: Harnessing the prowess of an intelligent control system, these brackets facilitate all-weather automatic sun tracking, optimizing solar energy capture. Tracking brackets distinguish themselves into flat single axis, oblique single axis, and dual axis tracking brackets. Incorporating such brackets into photovoltaic systems enables dynamic orientation adjustments, minimizing the angle between panels and direct sunlight, thereby boosting power generation by 10% to 25% or more.
4. Flexible bracket: Featuring an expansive photovoltaic module support structure with fixed ends, the core innovation lies in its prestressed flexible cable architecture. This ingenious structural system integrates numerous pivotal components, including cable structure, support, damping, and anchor systems. The flexible support design elevates photovoltaic modules to a significant height above ground, affording high clearance and reducing the necessity for pile foundations. This is particularly advantageous for expansive applications such as mountainous regions, barren slopes, water bodies, fishponds, and forested areas.
2, Component Parts
The photovoltaic bracket system is composed of the following critical elements:
1. Column: The foundational pillar that supports the entire system, typically anchored securely to a robust foundation.
2. Beam: Serving as the link between columns, these beams provide unwavering support to the photovoltaic modules.
3. Slant support: Crucial for enhancing the structural integrity of the support system, preventing potential tilting and deformation.
4. Connectors: Encompassing bolts, nuts, and other fastening elements, these connectors ensure secure assembly of the bracket's various components.
3, Functional Features
1. Support and fixation: Guarantees the steadfast installation of photovoltaic modules, withstanding external elements like wind and snow with unwavering reliability.
2. Optimize orientation and tilt angle: Enables precise adjustments to component orientation and tilt angle, maximizing the capture of solar radiation.
3. Extend system lifespan: Through innovative design, it minimizes component wear and damage, thereby prolonging system operation.
4. Adapt to various environments: Whether deployed on roofs, floors, or water surfaces, this system offers adaptable solutions for diverse environments.
4, Material selection
When selecting materials for photovoltaic brackets, considerations include weather resistance, load-bearing capacity, corrosion resilience, and economic viability. Popular materials comprise hot-dip galvanized steel, aluminum alloy, and stainless steel, each offering unique benefits tailored to specific needs.
