Mounting Structures for Solar Project Report: Industry Trends, Plant Setup, Machinery, Raw Materials, Investment Opportunities, Cost and Revenue

Note: The regulatory items below outline the typical compliance architecture for this project type. Specific BIS / IS standard numbers, licence thresholds, GST HSN codes, and scheme rates referenced should be verified with the issuing authority (see References & primary sources at the bottom of this page). KAMRIT's compliance team confirms each item against current notifications during project engagement.

Mounting structures for solar projects in India work under MNRE at the centre, the SERCs at state level, and the DISCOM that signs the PPA. For a project of this scale (₹3.0 crore - ₹65 crore), the licence and clearance path KAMRIT walks through is:

• Environmental clearance under EIA Notification 2006 above threshold capacity
• IEC 61215 / 61730 / 62804 product certification from accredited test labs
• State nodal agency approval (NEDA, MEDA, GEDA, etc.) and land-use conversion
• PLI National Programme on High Efficiency Solar PV Modules participation where eligible
• CEA Electrical Inspectorate sign-off plus grid synchronisation approvals from RLDC/SLDC
• Open-access wheeling and banking arrangement with the state DISCOM

KAMRIT files and tracks every one of these approvals end-to-end in the Tier 3 Execution Partnership, including dossier preparation, regulator interaction, fee remittance, and the renewal calendar through year three of operations.

<p>Demand for solar mounting structures in India is driven by two primary forces: accelerated utility-scale capital allocation toward large ground-mounted PV solar farms and a technological shift toward bifacial modules that require high-clearance, albedo-optimized, and rear-shading-resistant structural designs. The utility sector alone accounts for approximately 70.4% of the market share as of 2025, while the Commercial and Industrial (C&I) segment represents a fast-growing secondary demand center. West and Central India together account for 33.8% of the regional market concentration, with Rajasthan and Uttar Pradesh forming the North India cluster that dominates utility-scale ground-mounted solar park requirements due to high solar irradiance levels and large available land banks.

Uttar Pradesh has attracted notable investments such as RMC Switchgears' manufacturing facility announcement featuring 1 GWp annual production capacity for solar modules alongside matching mounting structure output.</p><p>Labor dynamics in solar plant construction underscore the structural importance of mounting work. Utility-scale solar construction requires approximately 2.5 to 3.5 full-time equivalent (FTE) jobs per megawatt (MW) installed, with structural mounting and mechanical assembly accounting for roughly 40% to 50% of total construction man-hours. Project execution teams demand a ratio of 1 skilled crew lead or equipment operator for every 3 to 4 semi-skilled laborers, reflecting the need for precision in alignment, torque specification, and foundation work.</p>

Project-specific demand drivers

• India 500 GW renewable target by 2030
• PLI scheme for advanced manufacturing
• ALMM domestic preference enforcement
• PM Surya Ghar Yojana driving rooftop demand
• Battery storage co-located mandates
• IRA-driven non-China export opportunity

<p>The solar plant mounting structure landscape encompasses several structural variants, each engineered for specific installation conditions and performance requirements. Ground-mounted fixed tilt structures represent the dominant category, priced between ₹100 and ₹150 per watt. Roof-mounted fixed tilt structures fabricated from hot-dip galvanized steel command prices between ₹60 and ₹100 per watt, or ₹6,000 to ₹12,000 per kW depending on height and material specifications.

Flush mount and tin shed structures using aluminum rails are priced at ₹3,000 to ₹4,500 per kW, offering a lightweight alternative for specific rooftop geometries. High-raised structures, designed for elevated mounting to optimize albedo reflection for bifacial modules, represent an emerging premium segment.</p><p>The advent of bifacial module technology is reshaping structural design requirements, driving demand for high-clearance mounting systems that optimize ground albedo reflection to the rear surface of bifacial cells. Solar trackers constitute a technologically advanced segment, with motorized tracking systems from manufacturers such as Nextracker and Array Technologies offering CAPEX ranging from $0.50 to $0.85 per watt for single-axis trackers and $0.80 to $1.50 per watt for dual-axis trackers.

The global solar tracker market was valued at USD 10.79 billion in 2025 and projected to reach USD 12.80 billion in 2026, with the solar tracker segment alone valued at USD 301.7 million in 2025 and projected to reach USD 474.4 million by 2034 at a CAGR of 5.00%. Active solar trackers held a 72.4% share of the tracker market in 2025, while the C&I tracker market was valued at USD 6.8 billion in 2025, scaling to USD 7.4 billion in 2026.</p><p>Manufacturing processes rely heavily on upstream raw materials including hot-rolled coils, structural steel, pre-galvanized steel, zinc-aluminum-magnesium steel, and aluminum extrusions sourced from primary domestic steel mills such as Tata Steel and JSW Steel, alongside metal processors. The midstream manufacturing layer consists of specialized manufacturers and Pre-Engineered Building (PEB) fabricators that convert raw steel into precision-engineered mounting systems, supported by downstream engineering, procurement, and construction (EPC) firms that integrate these structures into complete solar power plants.</p>

For projects in the ₹3.0 crore to ₹65 crore CapEx band, KAMRIT recommends a 70:30 debt-to-equity structure for manufacturing facilities above ₹20 crore CapEx, shifting to 60:40 for smaller facilities. State Bank of India (SBI) Renewables Desk and IREDA offer specialized lending at 8.5-9.5% for solar component manufacturers with tenor up to 10 years and 2-year moratorium. HDFC Green Finance and Axis Bank Sustainable Infrastructure verticals provide additional competitive quotes with 10-15 bps lower rates for ALMM-registered manufacturers. SIDBI's ₹10,000 crore Green Energy Transition scheme extends concessional rates at 7.5-8% for MSME-registered units in renewable supply chains. For working capital, a ₹45-60 day receivables cycle tied to government project timelines (30% advance, 60% on dispatch, 10% on installation acceptance) necessitates ₹2 crore to ₹8 crore in working capital limits, typically structured as Combined Credit Facility under RBI's Prescribed Margin Money scheme. CAP-1 (Credit Appraisal and Project financing) for manufacturing projects requires detailed capacity utilization projections: the DPR must demonstrate 65% capacity utilization in Year 2 and 80%+ by Year 4 to service debt at 1.25x coverage ratio. For projects targeting rooftop segment under PM Surya Ghar, GST input tax credit optimization and timely refund cycles (15-30 days) reduce working capital leakage. Margin profile by channel: direct EPC contracts yield 22-25% gross margins with 90-120 day payment cycles, while institutional distributors (through Select, Havells, and Syska channels) offer 28-32% margins with 45-60 day cycles.

<p>Raw material cost volatility represents the foremost operational risk for mounting structure manufacturers. Carbon steel in the form of raw hot-rolled coils commands prices between USD 700 and USD 900 per ton, accounting for 50% to 60% of total material costs, with extremely high sensitivity to fluctuations in iron ore and coking coal prices on global commodity markets. Zinc coating for hot-dip galvanization ranges between USD 200 and USD 400 per ton, representing 15% to 25% of material value, with very high sensitivity to London Metal Exchange (LME) zinc price movements.

These input cost exposures compress margins during commodity upswings and create unpredictable pricing environments for long-term EPC contracts that may be fixed-price or subject to limited escalation clauses.</p><p>Supply chain concentration risk persists despite strong domestic steel capabilities, as China remains the dominant global supplier for raw structural components and aluminum extrusions. Trade tensions, anti-dumping duties, or tariff escalations could disrupt access to competitively priced aluminum rails and specialized structural fittings. The GST rate of 18% on finished mounting structures, combined with input tax credit complexities, adds a layer of fiscal management overhead.

Labor availability and cost present another structural challenge, given that mounting and mechanical assembly work demands a specific skill mix of 1 skilled crew lead or equipment operator per 3 to 4 semi-skilled laborers, with 2.5 to 3.5 FTE workers required per MW installed.</p><p>The competitive pressure from the unorganized sector, which commands 35% of the market through a diffuse network of 50-plus regional suppliers, creates pricing competition that can erode margins for organized players, particularly in standardized fixed-tilt products. Policy and regulatory uncertainty around evolving BIS standards, potential revisions to wind load specifications, or changes to renewable energy subsidy and tender frameworks could require costly re-engineering or product re-certification. Furthermore, the transition to bifacial module-compatible structures and solar trackers, while representing an opportunity, also demands significant capital investment in new tooling, engineering capability, and supply chain partnerships, creating a barrier for smaller manufacturers unable to amortize such investments across sufficient production volumes.</p>
