Commercial & industrial rooftop solar mounting systems are designed to attach onto existing building roofs, while ground-mounted racking systems are built on open land with independent foundations. Their key differences are listed below. 1. Foundation & anchoring Commercial rooftop mounts use roof clamps, roof hooks or ballast blocks. No civil foundation work is needed, but roof load capacity and waterproofing must be verified. Ground mounting systems adopt driven piles, helical piles or concrete foundations. Soil testing and earthwork preparation are required. 2. Tilt & orientation design Rooftop solutions are constrained by the original roof slope and building direction; adjustment range is limited. Ground mounts can freely set optimal tilt angle and orientation to maximize power generation. 3. Structure type & load Rooftop racking pursues lightweight aluminum alloy structure to reduce extra roof load. Ground supports have stronger structural rigidity to withstand complex ground conditions and heavy snow/wind loads. 4. Installation & waterproof requirement For rooftop projects, penetration points must be carefully sealed to avoid roof leakage. Ballast-type solutions can achieve non-penetrating installation. Ground installation focuses on anti-corrosion of underground components, drainage and soil stability. 5. Layout & scalability Layout is restricted by roof vents, skylights and roof boundaries. Expansion is limited by available roof space. Ground stations enjoy flexible layout and convenient capacity expansion; single-axis solar trackers are also available as an option. 6. Maintenance & ventilation Modules on rooftops have limited air circulation, leading to higher operating temperature. Maintenance space is relatively tight. Ground arrays have better ventilation for higher power output, and easier access for cleaning and inspection.

1. Load conditions Wind load, snow load and dead load according to local building codes. The structure must bear the weight of PV modules and resist extreme weather. 2. Site & parking layout Parking bay size, vehicle height clearance, driveway width, column spacing and vehicle turning radius. Ensure convenient parking and passage. 3. Foundation type Options include concrete independent foundations, screw piles. Soil bearing capacity should be confirmed in advance. 4. PV module arrangement & tilt angle Module orientation and tilt angle to optimize power generation. Panel layout should avoid shading between rows. 5. Water drainage design Rainwater drainage channel on the canopy. Prevent water accumulation and leakage on the carport roof. 6. Material & anti-corrosion performance Hot-dip galvanized steel or aluminum alloy structure for long-term corrosion resistance, especially for coastal areas. 7. Safety requirements Structural fire protection, lightning protection and grounding system. Meet local safety and building standards. 8. Installation & construction condition On-site construction space, transportation access and project construction period.

Not all roof types are suitable for solar mounts. Installation feasibility depends on roof material, structural load capacity, age and waterproof condition. 1. Metal sheet roof (standing seam / trapezoidal metal roof) Widely used for commercial PV projects. Non-penetrating clamps are commonly adopted, with minimal damage to roof waterproofing. Need to check roof sheet thickness and bearing capacity. 2. Concrete flat roof Available. Ballasted solar mounts or penetrating bolted solutions can be used. Roof load test and waterproof reinforcement are required. 3. Tile roof (clay tile / concrete tile) Feasible with roof hooks. Tiles must be intact, and the underlying roof structure should have sufficient load capacity. Avoid fragile old tiles. 4. Asbestos roof / aging damaged roof****Not recommended. Such roofs are fragile, with poor load-bearing and waterproof performance. Renovation is required before PV installation. 5. Wood roof Only applicable after strict structural assessment. Wood structures usually have limited load capacity and require anti-corrosion and fireproof treatment. Key pre-check items: roof structural safety, remaining service life, waterproof integrity, and local wind/snow load standards.

1. Main material selection - Aluminum alloy (6063-T5): Lightweight, good corrosion resistance. Widely used for rooftop solar mounts. Suitable for inland and lightly corrosive environments. - Hot-dip galvanized carbon steel: High structural strength and lower cost. Ideal for ground stations, solar carports and heavy-load projects. Recommended for heavy snow or high wind areas. - Stainless steel (304 / 316): Excellent anti-corrosion performance. Mainly used for coastal, salt-fog and high-corrosion zones, often for fasteners and connectors. 2. Surface treatment options - Hot-dip galvanizing: For carbon steel. Thick zinc layer, long service life, suitable for outdoor ground projects. - Anodizing: For aluminum alloy. Anti-oxidation and scratch-resistant, stable in normal atmospheric environments. - Zinc-aluminum-magnesium coating: Superior corrosion resistance than ordinary galvanizing, good for coastal and humid areas. - Powder coating: Decorative and anti-corrosive, less common for main structural components of solar supports. 3. Core selection principles - Match material and coating with site environment: coastal salt spray, industrial pollution, rainfall and snowfall must be considered. - Meet local structural codes and design service life requirements (usually 25 years for PV projects). - Balance structural performance, corrosion resistance and total project cost. - Fasteners should be matched with main materials to avoid galvanic corrosion.
