What to Expect During Your Solar Panel Installation in Phoenix

One of the most common sources of anxiety for first-time solar buyers in the Phoenix Valley is not knowing what happens after they sign a contract. The process from decision to your first solar-powered bill involves multiple steps, multiple parties, and timelines that depend on permit offices, HOAs, equipment availability, and utility interconnection queues. The good news: when you work with Phoenix Valley Solar as your independent broker, we manage the process on your behalf and keep you informed at every stage. Here is the complete step-by-step guide to what happens during your solar installation in Goodyear, Sun City West, Scottsdale, Surprise, Fountain Hills, Sun City, and Sun Lakes.

Step 1: Site Assessment and System Design (Week 1 to 2)

Once you have signed with an installer, a site assessment technician visits your home to measure your roof, assess shading, inspect your electrical panel, and confirm structural suitability. This visit typically takes one to two hours. Based on the site data and your 12-month utility bill history, the installer produces a system design showing panel placement, estimated production, and projected bill savings. Phoenix Valley Solar reviews this design before you approve it to make sure the system is correctly sized and the production estimates are realistic.

Step 2: Permitting and HOA Approval (Week 2 to 6)

The installer submits permit applications to your city or county building department. In the Phoenix Valley, permit processing times vary: Goodyear and Surprise typically approve solar permits in 2 to 3 weeks. Scottsdale can take 3 to 5 weeks. Phoenix and Peoria generally run 2 to 4 weeks. If your community has an HOA, your installer must obtain architectural approval before permits can be issued in most cases, adding 1 to 4 weeks depending on when the HOA board meets.

Step 3: Equipment Ordering and Scheduling (Week 3 to 7)

While permits are processing, your installer orders your panels, inverters, and mounting hardware. Lead times for equipment are typically 1 to 3 weeks for in-stock items. If you have requested specific panel brands or battery systems, lead times may be longer. Once permits are approved and equipment arrives, your installation is scheduled. During peak season, typically May through August, installation slots can be 2 to 4 weeks out. Starting your process before spring means you avoid the summer backlog.

Step 4: Installation Day (1 to 2 Days)

Installation day is typically the smoothest part of the process. A professional crew of 3 to 6 technicians arrives in the morning and completes the roof work and electrical connections in 6 to 10 hours for a standard residential system. You do not need to be home for the entire day, though someone should be available at the start to grant access and at the end for a walkthrough. The crew mounts the racking system, installs the panels, runs conduit and wiring from the roof to the electrical panel, installs the inverter, and connects everything to your home's electrical system. The system is not turned on yet, pending inspection.

Step 5: City Inspection and APS or SRP Interconnection (Week 7 to 12)

After installation, a city or county inspector must sign off on the work. Inspection scheduling typically adds 1 to 2 weeks. Once the city inspection passes, your installer submits for utility interconnection, requesting Permission to Operate from APS or SRP. APS interconnection typically takes 1 to 3 weeks. SRP can take 2 to 4 weeks. Once Permission to Operate is granted, your installer activates the system and your solar production begins.

Step 6: Monitoring Setup and First Bill Review

Your installer sets up your system monitoring app, which shows real-time production data and cumulative generation. Phoenix Valley Solar recommends reviewing your first two APS or SRP bills after activation to confirm production is tracking within 5 percent of the modeled estimate. If production is consistently below projections, that is a signal to contact your installer. We remain available to our clients after installation to help interpret monitoring data and advocate for warranty claims if needed.
