Photovoltaic brackets serve as the cornerstone of photovoltaic power generation systems. Expertly designed to support, install, and secure solar panels, these brackets are integral to harnessing the sun's energy efficiently and reliably.
1, Classification
Depending on diverse application environments and specific installation requirements, photovoltaic brackets can be categorized into several distinct types:
1. Fixed bracket: Renowned for its robust stability, this type is ideal for scenarios that don't necessitate frequent adjustments. Once positioned, it remains stable, requiring comprehensive consideration of various factors like geographical location, environmental surroundings, and climate conditions during design. Fixed photovoltaic brackets are further classified based on usage scenarios into roof types (such as color steel plate roofs, sloping roofs, and flat roofs), ground types (including single and double column designs), and water surface types (like floating and column variants).
2. Adjustable tilt bracket: Sharing structural similarities with fixed brackets, these include an added adjustment mechanism for manual tilt angle flexibility. By routinely altering the bracket's tilt angle, users can match the solar incidence angle with seasonal variations, thus boosting direct sunlight absorption and enhancing photovoltaic module efficiency.
3. Automatic tracking bracket: Employing an advanced intelligent control system allows these brackets to autonomously track the sun throughout the day, optimizing solar energy use. They are mainly classified into flat single-axis, oblique single-axis, and dual-axis tracking brackets. Such systems automatically adjust component orientation based on lighting, minimizing the angle with direct sunlight and typically increasing power output by 10% to 25% or more.
4. Flexible bracket: Featuring a large-span support structure fixed at either end, its core comprises a prestressed flexible cable structure. This system integrates key elements like cable, support, damping, and anchor systems. With such innovative design, modules are elevated to offer high clearance, reducing the need for numerous pile foundations. Perfect for expansive scenarios such as mountainous terrains, barren slopes, water bodies, fishing ponds, and forests.
2, Component Parts
The photovoltaic bracket system comprises several essential components:
1. Column: The backbone that supports the entire system, typically anchored to the foundation.
2. Beam: Connects columns to provide stable support for photovoltaic modules.
3. Slant support: Enhances overall stability, safeguarding against tilting and deformation.
4. Connectors: Encompassing bolts, nuts, and more, these secure various bracket components firmly.
3, Functional Features
1. Support and fixation: Guarantees the stable and secure installation of photovoltaic modules, effectively resisting external influences like wind and snow.
2. Optimize orientation and tilt angle: Fine-tunes component orientation and tilt to maximize solar radiation capture.
3. Extend system lifespan: Thoughtful design reduces wear and damage, prolonging component longevity.
4. Adapt to various environments: Whether on rooftops, grounds, or water surfaces, versatile bracket solutions are available to meet diverse needs.
4, Material selection
When selecting materials for photovoltaic brackets, factors like weather resistance, load-bearing strength, corrosion resistance, and cost-effectiveness are pivotal. Commonly chosen materials include hot-dip galvanized steel, aluminum alloy, and stainless steel, each offering unique advantages.
