Solar Installation Process: What to Expect

A clear walkthrough from the first call to the moment your net meter starts spinning backward.

Solar installation process step by step

Step-by-Step Timeline

  1. Site Survey (Day 1-2): Roof assessment, shading check, load study, panel placement, inverter sizing.
  2. Proposal & ROI (Day 2-3): System size, bill savings, subsidy eligibility, financing options.
  3. Documentation (Day 3-5): MNRE subsidy form for residential/farm, ID proof, property proof, recent bill.
  4. Engineering (Day 4-6): BOM finalization, structural design, single-line diagrams, safety plan.
  5. Installation (Day 7-12): Mounting structure, panels, DC cabling, inverter, earthing & lightning protection.
  6. Net Metering (Day 12-20): TANGEDCO inspection, bidirectional meter approval, synchronization.
  7. 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.
