Your panels are a 25-year asset. The structure keeps them there.
Every Powermore installation uses pre-engineered, IS 875-compliant mounting designed specifically for your roof type, your wind zone, and your plant's load.
Not a commodity purchase. An engineered component.
In EPC, the structure is often treated as a line item to be value-engineered down. We treat it as a critical component of your plant's 25-year performance.
A structure that fails in Year 5 — because it was under-specified for wind load, or corroded because it wasn't rated for your coastal location — doesn't just cost you repair money. It costs you every unit of generation you miss while panels are off the roof.
Before we design your mounting system, we review roof type, load-bearing capacity, wind zone classification, and panel weight. Every structure comes with fabrication drawings, a site-specific load calculation, and a 10-year warranty.
Three structure families. Engineered for Indian conditions.
01Tin Shed & Metal Deck
The most common C&I rooftop in India is a corrugated or trapezoidal metal sheet. Our clamp-fit system locks directly onto your roof profile without a single penetration — waterproofing intact, roofing warranty intact.
- ▸Zero roof penetrations — no drilling, no voided waterproofing.
- ▸Rear ventilation gap designed in — panels run cooler, output stays higher through Indian summers.
- ▸Clamp-fit for all major profiles — corrugated GI, trapezoidal, standing-seam.
- ▸Hot-dip galvanised or anodised aluminium — corrosion-resistant grades for coastal zones.
- ▸Wind Zone I–V compliant — certified up to 180 km/h wind load.
02RCC Flat Roof
Commercial buildings, multi-storey factories, hospitals, IT parks — concrete flat roofs are where this structure earns its place. Two configurations: ballast-weighted (no drilling) and anchor-bolted (high wind zones).
- ▸Ballast or anchor-bolted — matched to your wind zone and structural load capacity.
- ▸East-West layout option — fits up to 30% more panels in the same roof area.
- ▸Dedicated O&M walkways — built into the structure for safe inspection.
- ▸Row spacing calculated per latitude — zero inter-row shading losses across the year.
- ▸Full structural load report — provided with every project.
03Ground-Mounted
Open land removes every constraint a rooftop imposes. Optimal tilt. Optimal orientation. Unlimited panel count. The highest possible yield per kW installed. Fixed-tilt and single-axis tracker systems available.
- ▸Fixed-tilt — lowest capital cost, highest reliability — no moving parts.
- ▸Single-axis tracker — +20–25% annual generation; financially compelling above 1 MW capacity.
- ▸Agrivoltaic option — panels at 2.5m+ clearance — land below remains productive.
- ▸Driven pile foundation — no concrete required; fully reversible.
- ▸Scalable from 500 kW to 10 MW+ — modular design.
Every structure we install includes the same baseline.
Site-specific load analysis
Calculated for your exact wind zone, panel weight, and roof or ground conditions.
IS 875 Part 3 wind compliance
Zone I through V — relevant to every state in India.
