Solar Mounting Rack / Photovoltaic Mounting Rack

Photovoltaic (PV) Mounting Structures
PV mounting structures are the core support systems for solar power generation, designed to securely position PV modules at optimal angles and spacing for maximum solar absorption. Common materials include aluminum alloy, carbon steel, and stainless steel. Carbon steel with hot-dip galvanization ensures 30-year outdoor rust resistance, while lightweight, corrosion-resistant aluminum alloy is ideal for residential rooftop applications.

Applications
1. Ground-Mounted: Utilize concrete foundations or metal piles, suitable for large-scale solar farms.
2. Rooftop-Mounted: Customized for flat/sloped roofs, installed via ballast or clamps to avoid structural damage.
3. Floating: Engineered for anti-wind/wave and salt-fog resistance, widely used in fishery-solar hybrid projects.

Types by Adjustability
- Fixed Mounts: Pre-set tilt angles for cost-effective, low-maintenance installations, popular in standard projects.
- Tracking Mounts: Single/double-axis systems track the sun’s movement, boosting energy yield by 10%-40%. Higher upfront costs make them suitable for high-latitude or high-irradiance regions.
- Flexible Mounts: Emerging in complex terrains (mountains, tidal flats), offering 35% steel savings with large-span, high-clearance designs.

Technical Requirements
Designed to withstand extreme conditions, including wind speeds up to 216 km/h, and ensure long-term durability through galvanization, anodization, and modular assembly. As PV expands into diverse landscapes, innovative mounting solutions continue to enhance efficiency and cost-effectiveness.
