1. Client Profile & Project Objective
Eagle Burgmann India Pvt. Ltd. is a globally leading manufacturer of industrial mechanical seals, expansion joints, and seal supply systems. Operating advanced CNC machinery, testing rigs, and precision cleanrooms at their Pune manufacturing facility, their operations require substantial and uninterrupted electrical power throughout the daytime.
With daytime industrial peak tariffs under MSEDCL HT-1 Industrial rate schedules exceeding ₹9.50 to ₹11.00 per unit (inclusive of TOD peak charges and regulatory surcharges), Eagle Burgmann sought a reliable, high-yield rooftop solar EPC partner to accomplish three critical goals:
- Aggressive Cost Reduction: Offset expensive peak daytime industrial grid units with self-generated solar electricity.
- Roof Membrane Protection: Guarantee 100% leakproof mechanical installation on their pre-engineered building (PEB) trapezoidal metal roof without drilling through structural sheets.
- Corporate Sustainability: Fulfill global ESG decarbonization mandates by abating over 240 metric tonnes of carbon emissions annually.
2. Site Engineering Constraints & Solutions
Industrial manufacturing roofs pose engineering complexities that standard residential rooftop installers cannot manage. E Green Solution addressed key structural hurdles:
Zero-Penetration Standing Seam Clamps
Drilling screws into metal factory roofs introduces chronic water leakage risks during Maharashtra’s intense monsoon season. E Green Solution deployed custom anodized aluminum non-penetrative clamps that grip the standing trapezoidal seams securely, preserving 100% roof waterproofing integrity.
Wind Load Dynamic Engineering (150 km/h)
The plant is located in an open terrain zone subject to high monsoon wind gusts. 3D structural wind-tunnel simulations were calculated to ensure all purlins, clamps, and SS-304 fastener hardware withstand uplift velocities up to 150 km/h (41.6 m/s) in full compliance with IS 875 (Part 3) standards.
3. Technical System Architecture
The 200 kWp plant uses high-efficiency Tier-1 Mono PERC half-cut solar photovoltaic modules coupled with multi-MPPT grid-tie industrial string inverters:

5. Generation Yield & Financial Payback
Since commissioning, the 200 kWp plant has consistently delivered robust generation metrics aligned with Pune's solar insolation profile:
- Annual Generation: Approximately 2,92,000 kilowatt-hours (kWh) of clean electricity generated per year.
- Annual Power Cost Savings: Over ₹22,50,000 saved per year in MSEDCL industrial electricity bills.
- Estimated Project Payback: 3.1 Years under direct CAPEX investment (accelerated further by Section 32 40% depreciation benefits for industrial machinery).
- Ongoing O&M: E Green Solution provides bi-weekly robotic/soft-wash module cleaning and quarterly thermographic drone scanning under an annual solar maintenance contract (Solar AMC).
