Solar Installation Process: What to Expect
A clear walkthrough from the first call to the moment your net meter starts spinning backward.

Step-by-Step Timeline
- Site Survey (Day 1-2): Roof assessment, shading check, load study, panel placement, inverter sizing.
- Proposal & ROI (Day 2-3): System size, bill savings, subsidy eligibility, financing options.
- Documentation (Day 3-5): MNRE subsidy form for residential/farm, ID proof, property proof, recent bill.
- Engineering (Day 4-6): BOM finalization, structural design, single-line diagrams, safety plan.
- Installation (Day 7-12): Mounting structure, panels, DC cabling, inverter, earthing & lightning protection.
- Net Metering (Day 12-20): TANGEDCO inspection, bidirectional meter approval, synchronization.
- Handover & Training: Monitoring app setup, O&M checklist, warranty docs.
Paperwork Checklist
- Latest TANGEDCO bill & service connection copy
- Aadhaar + property ownership proof
- Passport photo & PAN (for subsidy/loan)
- Load enhancement request if required
Common Delays & How We Prevent Them
- Net-metering: Pre-filled forms and follow-ups with TANGEDCO.
- Shadow issues: Panel layout optimized after drone/compass check.
- Material lead time: We pre-stock Tier-1 panels and MNRE-approved inverters.
FAQ
- Timeline? Most installs plus net metering finish in 10–20 days.
- Docs for subsidy? Aadhaar, PAN, recent TANGEDCO bill, property proof, photos, bank details.
- Backup? Choose hybrid inverter + batteries for power during outages.
