Photovoltaic brackets are the cornerstone of any photovoltaic power generation system. These essential components are meticulously engineered to support, install, and secure solar panels efficiently.
1, Classification
Photovoltaic brackets, tailored to diverse application environments and installation requirements, can be classified into several distinct types:
1. Fixed bracket: Known for its robust stability, this type of bracket is perfect for settings that require minimal adjustments. Once installed, it remains in position and is designed to consider factors like geographical location, environment, and climate. Fixed photovoltaic brackets are categorized into roof types (such as color steel plate roofs, sloping roofs, and flat roofs), ground types (like single and double columns), and water surface types (including floating and column structures).
2. Adjustable tilt bracket: This bracket shares a similar build with the fixed bracket but includes an innovative adjustment mechanism. The tilt angle can be manually adjusted, allowing seasonal or periodic alignment to the sun's path. This flexibility enhances direct sunlight absorption, boosting the power generation efficiency of photovoltaic modules.
3. Automatic tracking bracket: With an advanced intelligent control system, this bracket offers seamless all-weather automatic sun tracking. Subdivided into flat single-axis, oblique single-axis, and dual-axis tracking variants, it optimizes solar energy use. By adjusting the component's orientation based on lighting conditions, it reduces the angle with direct sunlight, typically increasing power generation by 10-25% or more.
4. Flexible bracket: This innovative large-span structure uses a prestressed flexible cable as its core, complemented by a cable structure, support, damping, and anchor systems. Designed for high clearance, it minimizes pile foundations, making it ideal for expansive settings like mountains, barren slopes, pools, ponds, and forests.
2, Component Parts
The photovoltaic bracket is composed of several key elements:
1. Column: The backbone of the support system, securely anchored to the foundation.
2. Beam: Connects columns to provide sturdy support for photovoltaic modules.
3. Slant support: Enhances stability, preventing any tilting or deformation.
4. Connectors: Comprising bolts, nuts, and other fixtures, these secure all bracket components firmly in place.
3, Functional Features
1. Support and fixation: Guarantees the stable installation of photovoltaic modules, effectively resisting environmental forces like wind and snow.
2. Optimize orientation and tilt angle: Adjusts component positioning to maximize solar radiation absorption.
3. Extend system lifespan: Smart design reduces wear and damage, prolonging component longevity.
4. Adapt to various environments: Offers custom solutions adaptable to roof, floor, or water surface installations.
4, Material Selection
Selecting materials for photovoltaic brackets involves assessing weather resistance, load-bearing capacity, corrosion resistance, and economic factors. Popular materials include hot-dip galvanized steel, aluminum alloy, and stainless steel for their durability and cost-effectiveness.
