Ground solar mounting systems are vital for securing photovoltaic (PV) panels, maximizing sunlight absorption, and ensuring long-term operational stability. Their installation involves systematic steps to adapt to diverse terrains, from open fields to sloped lands.
Pre-installation preparation is critical. First, conduct a site assessment: test soil bearing capacity to choose suitable foundations (e.g., concrete piles for soft soil, spiral piles for hard ground), analyze sunlight exposure to determine panel orientation (usually south-facing in the Northern Hemisphere), and check local regulations to obtain construction permits. Gather high-quality materials: corrosion-resistant 支架 (aluminum alloy or galvanized steel), weatherproof fasteners, and specialized tools like torque wrenches.
The core installation process has four key stages. First, foundation construction: dig holes or drive piles to a depth that resists frost heave (typically 0.8–1.5 meters), ensuring levelness. Second, assembly: connect rails and supports per design, aligning with laser levels to avoid deviations. Third, PV panel mounting: fix panels to rails with anti-vibration clamps, adjusting tilt angles (20–30 degrees for most regions) to optimize energy capture. Fourth, wiring and testing: install cables neatly, test electrical connections, and verify system operation with a multimeter.
Precautions must be followed. Apply anti-corrosion coatings to metal parts to withstand rain and humidity. Ensure proper drainage around foundations to prevent waterlogging. Regularly inspect fasteners post-installation to address loosening caused by wind or temperature changes. Prioritize safety: workers should wear insulated gloves and use fall protection when working on sloped sites.
Ground solar mounting installation, when done correctly, boosts PV system efficiency by 5–10% compared to improper setups. It also offers durability (service life over 25 years) and supports large-scale solar farms, contributing to clean energy transition.
