They'll use this data to finalize your system design and equipment selection.
Your installer submits permit applications to your local municipality and utility company. This is often the longest step — some towns take 2–4 weeks to approve.
Permits required typically include:
Once permits are approved, your installer orders panels, inverters, and mounting hardware. Lead times are typically 1–2 weeks. In 2026, supply chains have normalized — delays are rare.
The actual installation usually takes 1–3 days for a typical residential system:
Day 1: Roof mounting hardware, conduit runs, electrical work
Day 2: Panel installation, inverter mounting, wiring
Day 3 (if needed): Final connections, system testing, cleanup
A municipal inspector visits to verify the installation meets code. Then your utility company installs a new bidirectional meter and grants Permission to Operate (PTO).
You get the green light to flip the switch. Your installer walks you through the monitoring app and you start generating clean energy.
