Solar mounting structures: India market sizing in 2026
India's solar mounting structure market reached ₹4,500 crore in FY 2025, dominated by hot-dip galvanised steel structures from Tata Bluescope, Mahindra Sustainable Energy, and Rinac. Aluminum and corrosion-protected variants gaining share in coastal projects. Single-axis tracker pile and beam systems dominate utility-scale; rooftop uses lighter HDG products.
In 50 words: India's solar mounting structure market reached ₹4,500 crore in FY 2025, dominated by hot-dip galvanised steel structures from Tata Bluescope, Mahindra Sustainable Energy, and Rinac. Aluminum gaining share in coastal projects. Single-axis tracker pile-and-beam dominates utility-scale; rooftop uses lighter HDG products and emerging composite alternatives.
Market structure
India solar mounting market by segment (FY 2025):
- Utility-scale ground-mount: ₹2,400 crore (53%)
- Rooftop commercial: ₹1,300 crore (29%)
- Rooftop residential: ₹500 crore (11%)
- Floating solar: ₹180 crore (4%)
- Carports + specialised: ₹120 crore (3%)
Material choices
By material:
- Hot-dip galvanised (HDG) steel: 78% market share — workhorse for utility-scale
- Pre-galvanised steel (PG): 12% — lower-cost segment
- Aluminum: 7% — coastal and high-corrosion zones
- Composite/polymer: 2% — emerging in floating + niche residential
- Stainless steel: 1% — very specialised applications
Major suppliers
By revenue (rough rankings, FY 2025):
- Tata Bluescope Steel: integrated steel + structural
- Mahindra Sustainable Energy: structural systems + EPC
- Rinac India: solar-specific mounting structures
- Nextracker (India): single-axis trackers
- Array Technologies (India): single-axis trackers
- Sungrow trackers: emerging
- Local fabricators: extensive long-tail
Tracker structures
Single-axis tracker pile and beam systems:
- Imported trackers (Nextracker, Array Technologies, Sungrow): dominate >100 MW utility-scale
- Domestic tracker designs: emerging for smaller utility-scale
- Pile installation methods: ramming, screw piles, concrete foundations — site-specific
What's driving the market
- Utility-scale capacity additions
- Bifacial module adoption (taller racks for ground clearance)
- Tracker adoption (premium structures vs fixed-tilt)
- Coastal and high-corrosion zone project growth (aluminum + protected steel)
Where suppliers compete
Mid-tier and Tier 1 suppliers compete on:
- Steel quality and galvanisation certification
- Project-specific structural engineering capability
- On-site supervision and installation support
- Warranty terms (typically 10-year structural)
Low-end fabricators compete primarily on price for residential and small commercial.
What developers should consider
For 2026–2027 projects:
- Coastal/high-corrosion projects warrant aluminum or specialty steel
- Tracker selection affects structure specification significantly
- Bifacial requires higher rack heights (>1 meter ground clearance recommended)
- Soil testing before pile design is non-negotiable on sandy or saline soils
What to watch next
Carport and BIPV-driven mounting structure demand could grow 25%+ YoY through 2027 if commercial and architectural BIPV adoption accelerates as currently trending.
