Photovoltaic brackets stand as the backbone of any solar power generation system, meticulously crafted to support, mount, and secure solar panels with precision and reliability.
1, Classification
Photovoltaic brackets are ingeniously categorized based on diverse application environments and installation demands, offering a range of tailored solutions:
1. Fixed bracket: Engineered for robust stability, these brackets are ideal for installations that demand minimal alteration. Once positioned, adjustments are rare, necessitating a design that adeptly considers geographical positioning, environmental setting, and climatic conditions. Tailored to specific use cases, fixed photovoltaic brackets are further segmented into roof types (encompassing color steel plate roofs, sloping roofs, flat roofs, etc.), ground types (such as single and double column designs), and water surface types (both floating and column variants).
2. Adjustable tilt bracket: Bearing a resemblance to fixed brackets, these include a versatile adjustment mechanism that allows the tilt angle to be manually fine-tuned. By periodically modifying the tilt angle, these brackets adapt to seasonal or cyclical shifts in the sun's path, thus enhancing direct sunlight capture and boosting the photovoltaic modules' power generation efficiency.
3. Automatic tracking bracket: Harnessing an intelligent control system, these brackets perform all-weather automatic sun tracking to optimize solar energy utilization. They are categorized into flat single axis, oblique single axis, and dual axis tracking brackets. Systems with tracking brackets autonomously adjust component orientation based on light conditions, minimizing angles with direct sunlight and typically enhancing power output by 10% to 25%, or even more.
4. Flexible bracket: This innovative support system features a large-span photovoltaic module structure anchored at both ends, with a prestressed flexible cable forming its core. The system integrates vital elements such as cable structures, support mechanisms, damping, and anchoring systems. Flexible supports elevate photovoltaic modules off the ground, offering significant clearance benefits and minimizing pile foundation requirements. They are particularly advantageous in expansive scenarios like mountainous regions, barren slopes, water bodies, fishing ponds, and forested areas.
2, Component Parts
The photovoltaic bracket is composed of the following vital components:
1. Column: The foundational pillar, it supports the entire system, typically affixed securely to the base.
2. Beam: These connect the columns, providing structural support to the photovoltaic modules.
3. Slant support: These fortify the stability of the structure, preventing tilting and deformation.
4. Connectors: Comprising bolts, nuts, and more, these are essential in fastening the various components of the bracket.
3, Functional Features
1. Support and fixation: Guarantees the secure installation of photovoltaic modules, standing resilient against external forces like wind and snow.
2. Optimize orientation and tilt angle: Facilitates adjustments in component orientation and tilt to maximize solar energy absorption.
3. Extend system lifespan: Thoughtful design reduces wear and tear, ensuring longevity and durability.
4. Adapt to various environments: Whether installed on rooftops, ground, or water surfaces, there are solutions designed to fit every environment.
4, Material selection
When selecting materials for photovoltaic brackets, consideration of weather resistance, load-bearing capacity, corrosion resistance, and cost-efficiency is paramount. Commonly used materials include hot-dip galvanized steel, aluminum alloy, and stainless steel, each chosen for their specific properties.
