Photovoltaic brackets serve as the backbone of photovoltaic power generation systems, meticulously crafted to support, install, and secure solar panels with precision and reliability.
1, Classification
Depending on the specific application environments and installation demands, photovoltaic brackets are categorized into several distinct types:
1. Fixed bracket: Renowned for its robust stability, this bracket suits scenarios where minimal adjustments are necessary. Once its position is secured, the need for frequent modifications is eliminated. The design requires an in-depth evaluation of various factors such as geographical location, environment, and climate conditions. Fixed photovoltaic brackets are further classified based on application scenarios: roof types (including color steel plate roofs, sloping roofs, flat roofs), ground types (single and double column), and water surface types (floating, column).
2. Adjustable tilt bracket: Mirroring the structure of a fixed bracket but enhanced with a versatile adjustment mechanism, this bracket allows for manual flexibility in adjusting the tilt angle. By periodically modifying the tilt, it adapts to seasonal or cyclical changes, optimizing the solar incidence angle and, subsequently, enhancing photovoltaic module power generation efficiency.
3. Automatic tracking bracket: This advanced bracket employs an intelligent control system to achieve comprehensive automatic sun tracking around the clock, optimizing solar energy utilization. Tracking brackets are primarily categorized into flat single axis, oblique single axis, and dual axis tracking brackets. The photovoltaic systems utilizing these brackets can autonomously adjust component orientation to the prevailing lighting conditions, minimizing the angle between components and direct sunlight, which typically boosts power generation by 10% to 25% or more.
4. Flexible bracket: A state-of-the-art large-span photovoltaic module support structure characterized by fixed ends and a central prestressed flexible cable structure. This innovative system encompasses key elements such as cable structures, support systems, damping systems, and anchor systems. Flexible supports elevate photovoltaic modules to a significant height, achieving substantial ground clearance and reducing pile foundation requirements. This design is ideal for vast application landscapes including mountainous regions, barren slopes, water bodies, fishing ponds, and forests.
2, Component Parts
The intricate composition of a photovoltaic bracket comprises the following key components:
1. Column: The foundational element that holds up the entire support system, typically anchored to the base.
2. Beam: Connects the columns to form a sturdy framework for supporting photovoltaic modules.
3. Slant support: Provides additional stability, safeguarding against any tilting or deformation.
4. Connectors: Comprising bolts, nuts, and more, these secure the various components of the bracket together.
3, Functional Features
1. Support and fixation: Ensures stable and secure installation of photovoltaic modules, withstanding external forces such as wind and snow with resilience.
2. Optimize orientation and tilt angle: Adjusts the orientation and angle of components to harness maximum solar radiation exposure, enhancing efficiency.
3. Extend system lifespan: Through strategic design, it minimizes wear and tear on components, thereby prolonging the system's operational life.
4. Adapt to various environments: Whether on rooftops, ground, or aquatic surfaces, there are suitable photovoltaic bracket solutions for every scenario.
4, Material selection
Choosing the right material for photovoltaic brackets involves evaluating parameters such as weather resistance, load-bearing strength, corrosion resistance, and economic viability. Commonly used materials include hot-dip galvanized steel, aluminum alloy, and stainless steel.
