One of the most common concerns homeowners have when going solar is: how long will it take, and what’s involved with permits and inspections? While the Phoenix home solar installation process is straightforward, it does involve several important steps before your system can be powered on.

Here’s what you can expect when it comes to city permits, utility approval, and final inspections in the Phoenix metro area.

1. Site Assessment and System Design

Before anything is submitted to the city, your solar installer will complete a site visit to collect details about your roof, electrical panel, and utility usage. From there, your system is designed to:

• Maximize energy output

• Fit your roof layout and structure

• Comply with APS or SRP interconnection guidelines

• Include any upgrades, like EV charger wiring or future battery capacity

Design accuracy here ensures smooth approvals later.

2. Submitting Permit Applications

Once your design is finalized, your installer submits building and electrical permit applications to your city or county. In most cases across Phoenix, Scottsdale, Chandler, or Mesa, this includes:

• Structural review for solar panel mounting

• Electrical load calculations for your home’s main panel

• Fire and setback code compliance

• EV charger inclusion if you're charging an EV with solar panels

Permitting timelines vary by jurisdiction but typically take 1 to 4 weeks depending on the municipality and project scope.

3. Utility Interconnection Approval

At the same time, your installer will submit an interconnection application to your electric utility (APS or SRP). This step ensures your system can connect safely to the grid and outlines how excess energy will be credited to your account.

For homes considering EV integration, utilities may also ask how much does a home EV charger cost in Phoenix and whether it will affect your energy profile. These considerations help your utility assign the right rate plan or net billing arrangement.

4. Installation and City Inspection

Once permits are approved, installation typically takes just 1 to 2 days. After that, a city inspector visits your home to verify:

• Panels are installed per approved plans

• Wiring is safe and compliant

• Electrical connections are correct

• EV chargers (if applicable) are safely integrated

You don’t need to be present for this inspection, but your installer may request temporary access to the garage or electrical panel.

5. Final Utility Approval and System Activation

Once the city signs off, the final step is utility approval. APS or SRP may conduct their own inspection or simply issue Permission to Operate (PTO) after reviewing the paperwork.

From here, your system is activated and begins producing power. Your utility starts crediting you for solar exports, and the solar panel payback period in Arizona begins ticking.

6. Documentation for Long-Term Value

After your system is live, you’ll receive documentation to support monitoring, maintenance, and home resale. Do solar panels increase home value in Phoenix? Yes—especially when accompanied by clear production history, permits, and transferable warranties.

This paperwork adds credibility and transparency, which future buyers appreciate.
