Photovoltaic brackets serve as the backbone of photovoltaic power generation systems, meticulously crafted to support, install, and secure solar panels with precision.
1, Classification
Tailored to diverse application environments and installation needs, photovoltaic brackets are systematically categorized into an array of types:
1. Fixed Bracket: Renowned for its unparalleled stability, the fixed bracket is ideal for scenarios that demand minimal adjustments. Once positioned, it rarely requires changes, considering various factors such as geographical location, environmental surroundings, and climatic conditions. Based on usage scenarios, fixed photovoltaic brackets are sub-divided into roof types (encompassing 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: Mirroring the structure of a fixed bracket but enhanced with an additional adjustment mechanism, allowing for flexible manual tilt adjustments. Regularly modifying the bracket's tilt can adjust the solar incidence angle's turning point in response to seasonal or periodic changes, significantly boosting the direct sunlight absorption and enhancing photovoltaic modules' power generation efficiency.
3. Automatic Tracking Bracket: This innovative solution employs an intelligent control system for all-weather automatic sun tracking, maximizing solar energy utilization. Tracking brackets are primarily segmented into flat single axis, oblique single axis, and dual axis tracking brackets. Photovoltaic power generation systems employing a tracking bracket can autonomously adjust component orientation based on lighting conditions, minimizing angles between components and direct sunlight, potentially enhancing power generation by 10% to 25% or even more.
4. Flexible Bracket: Featuring a large-span photovoltaic module support structure with fixed ends, centered around a prestressed flexible cable structure. This structural system integrates key elements such as cable structures, support systems, damping systems, and anchor systems. Flexible support designs elevate photovoltaic modules above the ground by a specified height, offering high clearance benefits and reducing the number of pile foundations. It is particularly advantageous for expansive application scenarios like ordinary mountains, barren slopes, water pools, fishing ponds, and forests.
2, Component Parts
A photovoltaic bracket is composed of the following critical components:
1. Column: Provides foundational support for the entire system, typically anchored to the foundation.
2. Beam: Interlinks the columns, offering robust support for photovoltaic modules.
3. Slant Support: Augments system stability, effectively preventing tilting and deformation.
4. Connectors: Comprising bolts, nuts, etc., these are crucial for securely affixing various bracket components.
3, Functional Features
1. Support and Fixation: Ensures steadfast installation of photovoltaic modules, effectively combating external forces like wind and snow.
2. Optimize Orientation and Tilt Angle: Facilitates adjustment of component orientation and tilt angle, optimizing solar radiation capture.
3. Extend System Lifespan: Through strategic design, mitigate component wear and minimize damage.
4. Adapt to Various Environments: Whether on roofs, floors, or water surfaces, tailored photovoltaic bracket solutions are readily available.
4, Material Selection
Selecting materials for photovoltaic brackets involves considering weather resistance, load-bearing capacity, corrosion resistance, and economic factors. Common selections include hot-dip galvanized steel, aluminum alloy, and stainless steel.
