What Happens After Your Home Is Approved for Solar Panel Installation

Final Inspection and Connection

Once the installer finishes mounting the panels, a certified electrician conducts a final inspection to verify wiring, grounding, and compliance with local codes. The utility company may also require a separate inspection before granting permission to feed electricity back into the grid.

Permits and Documentation

All required permits—building, electrical, and sometimes zoning—must be closed out. Installers typically submit the final paperwork to the city or county, and you should receive copies of the signed permits, the as‑built drawings, and the warranty documents.

System Activation and Net Metering

After the utility approves the interconnection, the inverter is switched on and the system begins producing power. If your agreement includes net metering, excess electricity flows to the grid and is credited to your account, reducing future bills.

Monitoring and Performance Checks

Modern installations come with a monitoring portal or app that displays real‑time generation, daily totals, and system health alerts. Review the first week's data to confirm the expected output based on your roof orientation and local irradiance.

Maintenance Basics

Solar panels require minimal upkeep—periodic cleaning to remove dust or debris and an annual visual check for loose mounting or shading changes. Most manufacturers offer a 25‑year performance warranty and a 10‑year product warranty.

Financial and Tax Follow‑Up

Submit the final installation invoice and any required forms to claim the federal Investment Tax Credit (ITC) and any state or local rebates. Keep these records for at least seven years in case of an audit.

Common Questions

• Will my homeowner's insurance change? Often the policy is updated to cover the solar equipment at its replacement value.
• What if I sell the house? Solar agreements typically transfer with the property, and the system can increase resale value.
• Can I add more panels later? Yes, provided the inverter and structural capacity can accommodate expansion.
