What Greentek does

Greentek India Limited is an integrated solar energy company founded in 1997 and headquartered in Secunderabad/Hyderabad, India. The company operates across the full solar value chain, combining engineering, procurement and construction (EPC) services with in-house manufacturing of photovoltaic modules and mounting structures, plus a software layer for asset performance management. Its manufacturing footprint includes 50 MW of annual PV module capacity and approximately 2,400 tons of module mounting structure (MMS) capacity, supporting both captive projects and third-party supply. The company reports 3.2+ GW of cumulative installed capacity across 1,200+ projects, with utility-scale experience as a sub-contractor on marquee Middle East projects including DEWA VI (1,000 MW) and Al Dhafra PV2 (2.1 GW) under Larsen & Toubro.

The company's core technology stack centers on Green Sage AI, an energy intelligence platform that delivers predictive analytics, anomaly detection, SCADA-grade monitoring and explainable AI for root-cause analysis across solar portfolios. It is complemented by a battery energy storage system (BESS) offering and a 25-year operations and maintenance (O&M) service contract model designed around the design life of utility-scale assets. The business generates revenue through three primary streams: (1) utility-scale and commercial & industrial (C&I) EPC contracts, (2) manufacturing sales of PV modules and MMS to channel partners and direct buyers (including an Adani Solar distribution arrangement), and (3) recurring O&M and AI-driven monitoring subscriptions. Customer segments span residential, SMB, C&I enterprises (e.g., Kajaria Ceramics, Nitya Packaging) and large utility off-takers, with distribution supported by bank financing partnerships (SBI, HDFC and others) under India's PM Surya Ghar scheme.

Geographically, Greentek has expanded beyond its Indian base into the UAE (Dubai hub established in 2022), Kenya and the United States. The company employs 212+ professionals and has established Greentek Vasistron as a dedicated MMS subsidiary to deepen vertical integration. Its go-to-market combines direct enterprise sales for C&I and utility clients, a residential channel leveraging government subsidy programs, and a distribution network for component sales — positioning it as a mid-tier domestic player with international project credentials and an emerging software-as-a-service angle through its AI platform.

Revenue model

1. Solar EPC — Project Execution: One-time Engineering, Procurement & Construction revenue from installing solar PV systems (residential, commercial, industrial, utility-scale). Customers pay upfront for system design, equipment procurement, installation, and commissioning. CAPEX model customers own the asset after ROI period. Revenue is project-based with typical payback of 3–5 years for C&I customers.
2. Operations & Maintenance (O&M) Services: Recurring revenue from performance monitoring, preventive/corrective maintenance, asset management, AMC contracts, warranty management, and real-time reporting for installed solar plants. O&M is provided across residential, C&I and utility-scale plants under long-term contracts (typically 25-year design life). Enables predictable recurring revenue streams and customer retention.
3. OPEX / PPA Solar Model: Under OPEX/PPA arrangements, Greentek or its financing partners retain ownership of the solar asset. The customer purchases electricity generated at a tariff below the grid rate, with no upfront capital expenditure. Greentek earns revenue per unit of electricity generated over the contract term, providing long-term recurring income and alignment of incentives for system performance.
4. Manufacturing — Solar Components & Module Mounting Structures: Revenue from manufacturing and selling solar components including PV modules (50 MW capacity), solar thermal collectors (FPC/ETC), module mounting structures (via Greentek Vasistron subsidiary, 2400 tons/year capacity), solar water heaters, and IoT energy monitors. Manufacturing serves both internal EPC needs and external channel partners/dealers.
5. Green Sage AI Monitoring Platform: AI-driven solar performance monitoring and SCADA intelligence platform for utility-scale, C&I, and distributed rooftop solar portfolios. Generates revenue as part of O&M service contracts and standalone monitoring subscriptions for asset owners and operators seeking predictive maintenance and ROI optimization.
6. Channel Partner / Dealer Product Sales: Revenue from selling certified solar products (panels, inverters, mounting structures, water heaters) and solutions to channel partners (dealers, EPC partners, installers). Partners receive competitive margins and tier-based pricing, enabling Greentek to scale distribution without direct sales costs. Recurring revenue through O&M and service contract referrals.
