How Long Does Solar Installation Take in Arizona?

The complete solar installation timeline in Arizona typically spans 6-10 weeks, though this can vary based on several factors including permit approval times, inspection schedules, and utility interconnection processes. According to EnergySage data for Arizona, most installations follow this timeline breakdown:

• Week 1-2: Site survey, engineering, and design completion
• Week 2-6: Permit submissions and approvals (city and HOA)
• Week 4-5: Physical installation (1-2 days of actual work)
• Week 6-8: City and utility inspections
• Week 8-10: Utility meter installation and system activation

This timeline reflects Arizona’s favorable solar climate and established regulatory processes that have been refined over years of solar adoption. Solar Topps consistently meets or beats these timelines through our streamlined approach and local relationships.

Step 1: Site Survey and Engineering Your Solar System Installation

The moment we receive your order, we schedule a time for our site surveyor to visit your property within a day or so. This rapid response time sets Solar Topps apart from national installers who may take weeks to schedule initial assessments. Typically, you do not need to be home for this phase unless we are installing components inside the home.

During the site survey, our certified technicians inspect your roof structure and condition, analyze potential shading from trees or nearby structures, photograph your electrical service panel, and confirm precise measurements needed to finalize your system’s optimal design. We also assess utility-specific requirements based on whether you’re served by APS, SRP, or other Arizona utilities.

Our team takes the information gathered about your solar panel installation process and shares it with our in-house engineering team. Unlike companies that outsource engineering work, our integrated approach takes about two weeks to analyze all documents and provide fully engineered, completed plans ready for your approval.

We’re happy to discuss any details with you to ensure you understand the modifications made to the original design following our site survey results. This transparency is crucial because Arizona’s unique climate conditions – including extreme heat, monsoon seasons, and intense UV exposure – require specific design considerations that NABCEP-certified installers understand.

Step 2: Arizona Solar Permits and Professional Installation

Once you approve the final design, we submit these engineered plans and other project documents to the appropriate City Permitting Department and your HOA, if applicable. Arizona’s streamlined interconnection process has improved significantly in recent years, but approval timelines can still take two to four weeks depending on local government workloads.

Solar Topps maintains relationships with permitting departments throughout Arizona, from Phoenix and Scottsdale to Tucson and Flagstaff. We follow up proactively with the right contacts in these departments to expedite your project through the approval process. Our experience with local building codes and Arizona Corporation Commission requirements helps avoid common delays that inexperienced installers encounter.

Once permits are approved, we’re ready to begin the actual installation. Our trained installers – not third-party contractors – perform all installations. Solar Topps provides our installation crews with fully equipped trucks, ensuring they have all necessary tools and equipment to complete your installation correctly on the first attempt.

Most residential solar system installations take one to two days to complete, significantly faster than the industry average of 1-3 days. Our surplus of supplies in our onsite Phoenix warehouse allows us to begin projects faster than competitors who await parts shipped to their location or your home. When we receive necessary approvals, we can immediately place you on our installation schedule, minimizing any downtime.

We also perform commercial installations using the same efficient processes, scaled appropriately for larger projects and different regulatory requirements.

Step 3: Inspections and System Activation Process

Once your system is installed, our team conducts temporary testing to ensure no faults exist and that all components meet our internal quality standards. This preliminary testing catches potential issues before official inspections, preventing delays in the approval process.

After passing our internal quality check, appropriate documentation is sent to both the City building department and your utility company for required inspections. According to APS interconnection guidelines, inspection approvals typically take between two to three weeks, though this varies by jurisdiction and season.

We work closely with local inspectors to expedite your project through the approval process. Our established relationships and thorough documentation help ensure inspections pass on the first attempt, avoiding costly re-inspection delays that can extend project timelines.

Once inspections are approved, your utility company schedules a date to install a new net meter that makes your electrical system solar-compatible. This utility interconnection process can take an additional two to three weeks, depending on the utility’s current workload and your location within their service territory.

When your meter is switched and the system is ready for activation, Solar Topps provides comprehensive system orientation. We guide you through the startup process and ensure you understand how to monitor your system’s performance using manufacturer apps and monitoring systems. This education helps you maximize your investment and quickly identify any potential issues.
