Distributed across 9 institutional rooftop structures using non-invasive standing seam clamps. Integrated with existing diesel backup generators via smart zero-export and fuel-saver controllers.
FREQUENTLY ASKED TECHNICAL QUESTIONS
Direct engineering answers for facility heads, plant managers, and electrical chief engineers.
Our Turnkey EPC covers end-to-end execution: feasibility audits, 3D shading CAD design, global procurement of Tier-1 modules/inverters, civil foundation, structure erection, electrical DC/AC wiring, and final grid synchronization with DISCOMs.
We deploy dedicated on-site Resident Project Managers and utilize digital daily tracking tools. Contractual milestones are bound by strict timelines with liquidated damage clauses to guarantee on-time Commissioning (COD).
A2S handles 100% of regulatory liaison work. Our in-house desk manages CEIG approvals, DISCOM grid feasibility studies, quota reservations, and bi-directional net-meter installation so you experience zero bureaucratic friction.
All equipment warranties (e.g., 25-30 years for modules, 10 years for inverters) are passed directly to the client with full documentation. We also provide extensive operation and maintenance (O&M) defect liability periods post-commissioning.
