Common Questions About
Solar EPC Services

Everything you need to know before choosing an EPC contractor for your solar project.

A solar installer typically only handles the physical installation of panels and inverters. An EPC (Engineering, Procurement & Construction) contractor takes single-point responsibility for the entire project — from engineering design and permits, to material procurement, construction, testing, grid connection, and handover. With an EPC contract, you deal with one accountable party instead of multiple vendors. For projects above 100kW, EPC is strongly recommended.
For formal EPC contracts with full project management and documentation, our minimum project size is typically 100kW. However, we handle smaller commercial systems (25kW–100kW) under our commercial installation service. For large-scale utility or industrial projects, we have executed plants up to 50MW+ and can scale further through our network of partner contractors.
Project timelines depend on size and complexity. As a general guide: 100kW–500kW rooftop: 4–8 weeks. 500kW–2MW ground-mounted: 2–4 months. 2MW–10MW: 3–6 months. 10MW–50MW: 6–12 months. These timelines include engineering, procurement, construction, and commissioning. Approval timelines from DISCOM or government bodies may add 2–6 weeks and are outside our direct control, though we actively manage and expedite these.
Yes. For EPC projects, we provide a Performance Ratio (PR) guarantee as part of the contract — typically a minimum PR of 75–80% depending on location and system type. We also provide a 5-year workmanship guarantee on our construction work, in addition to the 25-year panel performance warranty and 5-year inverter warranty from Tier-1 OEMs. Any underperformance against guaranteed PR is addressed under the O&M contract terms.
Yes. Sangam Power has experience with government tender-based EPC projects including MNRE, SECI, UPNEDA, RRECL, and state DISCOM tenders. We also support RESCO (Renewable Energy Service Company) and PPA (Power Purchase Agreement) model projects where the client pays per unit of electricity generated rather than upfront capital. Please contact us with your specific tender details or business model requirement and we will advise on the most suitable engagement structure.
