Guojian offers you the Ground Dual‑Post Solar Mounting System, which is supplied in large quantities directly from the factory. It comes with export-grade packaging, complete technical documentation and certification materials, providing an economical and efficient fixed-tilt installation solution for both domestic and international ground-based photovoltaic projects.
1. Main Material: Q235B/Q355 high-strength carbon steel; surface treatment options include hot-dip galvanizing or Zinc-Aluminum-Magnesium alloy coating for corrosion resistance.
2. Corrosion Resistance Standards: Hot-dip galvanized coating thickness ≥65μm; Zinc-Aluminum-Magnesium coating features self-healing anti-corrosion properties, suitable for high-humidity and coastal salt-spray environments.
3. Compatible Modules: Compatible with mainstream 182/210 series PV modules; supports both landscape and portrait array configurations.
4. Installation Tilt Angle: Customizable between 5° and 60°; optimal angle determined based on local latitude and projected power generation.
5. Load Design Standards: Standard base wind pressure of 0.3–0.75 kN/m²; snow load capacity up to 1.8 kN/m²; specialized reinforcement solutions available for high-wind and heavy-snow regions.
6. Ground Clearance: Customizable from 0.6m to 2.8m to accommodate passage and mechanical operations beneath the panels.
7. Foundation Types: Screw piles, independent concrete footings, or cast-in-place piles; suitable for various soil conditions including sandy soil, clay, and rock.
8. Fasteners: Hot-dip galvanized high-strength bolts with standard anti-loosening washers; designed to remain secure during long-term outdoor use.
9. Design Service Life: 25 years, matching the lifecycle of the PV modules.
✅ Large-scale centralized grid-parity ground-mounted PV power plants
✅ Village-level distributed PV and rural revitalization PV projects
✅ PV bases in Gobi deserts, wasteland, or gently rolling hills
✅ Agri-PV (agrivoltaic) projects (clearance provided beneath panels for agricultural machinery)
✅ Large-scale overseas ground-mounted PV farms and EPC projects
✅ Flat terrain with stable soil and water conditions suitable for pile foundation construction
1. Conduct a site geological survey prior to construction and select the foundation type based on the geological report; proceeding with construction without a survey is strictly prohibited. 2. Ensure all uprights remain vertical and the array axes are aligned; the mounting tilt angle must strictly adhere to the design drawings—on-site angle modifications are prohibited.
3. Use only standard, original-manufacturer components for assembly; unauthorized on-site welding, cutting, drilling, or bending of main profiles—which could compromise the anti-corrosion coating or structural integrity—is strictly prohibited.
4. Upon completion of the mounting system installation, establish a unified grounding connection to ensure compliance with lightning protection standards for photovoltaic power plants.
1. Conduct comprehensive inspections annually following flood seasons, heavy snowfalls, or typhoons, focusing on bolt tightness, upright settlement, and damage to anti-corrosion coatings.
2. Promptly repair any localized damage to the coating using specialized anti-corrosion materials to prevent the spread of rust.
3. Do not hang equipment or stack heavy objects on the mounting beams or uprights; loads must not exceed the original design specifications.
4. When replacing damaged parts, use only original-manufacturer components of the same specifications; the use of non-standard profiles is prohibited.
Upon receipt of site topographic maps and meteorological data, professional structural engineers perform modeling and verification, generate layout and tilt-angle optimization plans, and provide cost-efficiency comparisons.
Adjust upright height, span, and foundation type based on wind and snow loads, geological conditions, and land-use planning.
In-house manufacturing and modular prefabrication; production and delivery scheduled in batches according to demand; standardized container packaging suitable for ocean export to minimize transit damage.
Provide Ground Dual‑Post Solar Mounting System certificates of conformity, material reports, drawings, and load calculation reports with the shipment; arrange technical personnel to address on-site installation queries. Authoritative Qualifications and Certifications
✅ ISO 9001 Quality Management System certification; standardized control across the entire production process with full traceability
✅ CMA third-party mechanical performance test reports
✅ CNAS-accredited laboratory reports on material properties and corrosion/weather resistance
✅ Ability to provide EN 1090 technical documentation compliant with EU standards for European projects
✅ Comprehensive material specifications and salt spray corrosion test reports to meet audit requirements for overseas projects in Southeast Asia, the Middle East, and Latin America
