Rooftop Solar Module Mounting Structures
Structure cost is 8-12% of your total solar plant budget. Overspend here, you’re eating margin. Underspec it, you’re replacing bent purlins after the first monsoon or dealing with module alignment issues that cost 3-5% generation loss annually.
Rooftop solar module mounting structures from Vaibhav Laxmi Industries balance structural adequacy against material cost. We don’t over-engineer—85 micron HDG coating instead of unnecessary 120 micron, C-channel instead of heavier I-beam where calculations permit, optimized member sizing that meets IS 875 wind load without excess steel tonnage.
Ground Mount Structures: Fixed-tilt arrays for utility-scale and commercial installations. MS angle/channel frame with C or Z purlins. Portrait or landscape module orientation. Standard tilt angles 15°-25° (latitude-optimized). Foundation options: driven pile, concrete block, or RCC foundation depending on soil bearing capacity.
Rooftop Structures: Flat roof ballasted (non-penetrative) or elevated type. Corrugated/trapezoidal sheet roof rail-mount system. RCC terrace structures with concrete block foundation. Clearance height 300mm-3000mm based on requirement.
Material Specifications:
