Photovoltaic brackets play a crucial role in the realm of photovoltaic power generation systems, tailor-made to proficiently support, install, and secure solar panels with utmost precision.
1, Classification
Depending on the diverse application environments and distinct installation prerequisites, photovoltaic brackets are categorized into various sophisticated types:
1. Fixed bracket: Known for its robust stability, this type is ideal for settings requiring minimal adjustment. Once positioned, it generally remains unchanged, with its design meticulously considering factors such as its geographical setting, the surrounding milieu, and climatic conditions. Based on its application, fixed photovoltaic brackets are further classified into roof types (like color steel plate roofs, sloping roofs, and flat roofs), ground types (including single column, double column variants), and water surface types (such as floating, column options).
2. Adjustable tilt bracket: This variant mirrors the structure of a fixed bracket but is enhanced with a versatile adjustment mechanism. Its tilt angle is manually adaptable, allowing periodic adjustments to optimize the incidence of solar angles with seasonal or periodic shifts. This strategy amplifies direct sunlight absorption, significantly boosting the photovoltaic modules' efficiency in power generation.
3. Automatic tracking bracket: Equipped with an intelligent control system, this bracket offers seamless all-day sun tracking, optimizing solar energy collection. It comes in types like flat single-axis tracking, oblique single-axis tracking, and dual-axis tracking. Systems utilizing this bracket autonomously adjust component orientation to lighting conditions, minimizing angles with direct sunlight and typically enhancing power output by 10% to 25% or more.
4. Flexible bracket: Featuring a large-span support for photovoltaic modules with fixed ends, this system is centered around a prestressed flexible cable structure. It encompasses vital components like cable structure, support, damping, and anchor systems. This design elevates modules above the ground, offering high clearance and minimizing pile foundations, perfectly suited for vast applications in challenging terrains like ordinary mountains, barren slopes, water bodies, fishing ponds, and forests.
2, Component Parts
The photovoltaic bracket is an assembly of the following essential components:
1. Column: The backbone supporting the entire structure, typically affixed to a stable foundation.
2. Beam: It skillfully bridges columns, offering enduring support to photovoltaic modules.
3. Slant support: Ensures enhanced stability, preventing any tilting or deformation of the structure.
4. Connectors: Essential elements like bolts and nuts, crucial in securing various components of the bracket efficiently.
3, Functional Features
1. Support and fixation: Guarantees stable installation of photovoltaic modules, withstanding external forces such as wind and snow.
2. Optimize orientation and tilt angle: Skillfully adjusts component orientation and angle to capture maximum solar radiation.
3. Extend system lifespan: Through astute design, it minimizes wear and damage, enhancing component longevity.
4. Adapt to various environments: Be it on a rooftop, ground, or over water, the bracket offers tailored solutions fit for every scenario.
4, Material selection
In selecting materials for photovoltaic brackets, considerations include weather resistance, load-bearing capacity, corrosion resistance, and economic viability. Popular choices are hot-dip galvanized steel, aluminum alloy, and stainless steel.
