A residential solar project involves more than placing panels on a roof. First, an installer reviews your electricity use and property, then designs a system and obtains required approvals. Once permits are in place, the crew installs the equipment and an inspector checks the work. Your utility may also need to approve the connection before the system can operate. Knowing what happens at each stage helps you prepare and ask useful questions.
Review Your Home and Energy Use
The process usually starts with a conversation about your electricity bills, household needs, and goals. The installer may ask for recent utility statements to understand how much power you use and when. They will also assess whether your roof has suitable space and condition, and look for shading from trees or nearby structures. In some cases, a site visit or remote review helps identify details that affect the design.
This review helps determine an appropriate system size, but it does not guarantee that solar will cover every bill. Energy use can change, and utility rules affect how exported electricity is credited. Ask which assumptions the proposal uses, whether roof repairs may be needed first, and what equipment is included. Clear answers make it easier to compare proposals based on the same goals.
Design and Obtain Approvals
After assessing the property, the installer prepares a system design showing panel placement, wiring, and major equipment. The design should account for roof layout, electrical capacity, and applicable safety requirements. Review the plan and ask how it fits your expected energy use. If the proposal includes a battery, confirm where it will go and what loads it is intended to support during an outage.
Before work begins, the installer typically submits plans for local building and electrical permits. The utility may require a separate application to connect the system to the grid. Review times and requirements vary, so the schedule can depend on agencies outside the installer's control. Ask who handles each submission, what approvals are still pending, and whether you need to provide documents or make decisions.
Install the Solar Equipment
Once the required permits are approved, the installer schedules the work. The crew mounts the panels and installs the inverter, wiring, and any other equipment included in the design. Work may take one or more days depending on the system and property. Before installation, clear access to the work area and discuss where workers can park, how they will reach the roof, and whether anyone needs to be home.
The crew should follow the approved plans and applicable safety practices. Ask the installer how changes will be handled if the team finds an unexpected issue, such as damaged roofing or an electrical condition that needs attention. Before the crew leaves, confirm what work is complete, what remains, and how to contact the project team. The system may not be ready to operate immediately after installation.
Complete Inspections and Activation
After installation, the local authority usually inspects the work to confirm it meets approved plans and applicable codes. The utility may also review the system or meter connection before granting permission to operate. If an inspection identifies an item to correct, the installer arranges the needed work and requests any required follow-up approval. Ask for copies of approvals and a clear explanation of the remaining steps.
Wait for the required utility authorization before turning on a grid-connected system. Your installer should explain the startup process, monitoring app, and basic equipment indicators. Keep the system documents and warranty information together, and learn whom to contact if monitoring shows an issue. Sonoran Solar can walk Phoenix homeowners through these stages and explain what to expect for a specific property.
A solar project moves from property and energy review through design, permitting, installation, and final approvals. The exact sequence and timing depend on your home and local requirements, but a clear project plan can reduce surprises. Ask your installer to explain responsibilities, pending approvals, and the steps needed before activation.
