Whether you want zero-upfront via PPA, full CAPEX ownership, or SunstoX crowd-funded model — we design and deliver the right structure for your site.
India's rooftop solar policy stack has never been more favourable. SunstoX manages every regulatory touchpoint so you just sign the installation order.
SunstoX manages every step from feasibility to DISCOM commissioning and PM Surya Ghar subsidy credit. You receive one point of contact throughout.
Roof area measurement, shadow analysis, structural load check, energy audit from 12-month bills
Net metering feasibility, technical sanction letter, check-meter installation approval from DHBVN / UHBVN
National portal registration, vendor selection, subsidy pre-approval (residential only)
Panel mounting, inverter wiring, earthing, protection equipment, internal commissioning test
DISCOM engineer inspects and issues commissioning certificate. Bi-directional meter installed. System goes live.
PM Surya Ghar DBT credited to Aadhaar-linked account within 30–45 days. SunstoX tracks and escalates if delayed.
Enter your monthly bill and available roof area. We'll estimate system size, savings, subsidy, and payback.
SunstoX is uniquely positioned as both an EPC contractor and a crowd-investment platform — giving you options no pure EPC can offer.
Design, procurement (ALMM modules, BIS inverters), civil work, electrical commissioning, and DISCOM coordination — single-vendor accountability from Day 1 to energisation.
Schools get zero-capex solar. Parents invest and earn 10.66% IRR. SunstoX holds the PPA and manages the full investment lifecycle — no other EPC offers this.
We register your application, coordinate the DISCOM inspection, and track your DBT payment status — escalating to the nodal agency if credit is delayed beyond 45 days.
Every system above 10 KWp includes a SCADA monitoring feed. View your live kWh generation, CO₂ offset, and generation vs forecast from your investor or owner dashboard.
Fire, storm, lightning, equipment breakdown, and theft cover at 100% replacement value. Policy arranged at project level — you never interact with the insurer directly.
Scheduled cleaning, inverter health checks, junction box inspection, and performance reporting every quarter. Available as 3-year or 5-year O&M packages post-commissioning.
A SunstoX solar engineer will contact you within 24 hours to arrange a free site visit, energy audit, and detailed savings proposal.
