Tempe requires a building permit for residential solar panel installations covering both electrical and structural components. The city has streamlined the solar permitting process. Inspections verify proper installation and compliance with the National Electrical Code. Most residential rooftop installations are approved within a few business days of complete application.
Solar panel installations in Tempe require a building permit that covers both the electrical system (inverters, wiring, utility interconnection) and structural components (roof mounting, racking). The city has worked to streamline solar permitting, and standard residential rooftop installations on code-compliant roofs are typically processed quickly. Required documentation includes system specifications, site plan showing panel layout, electrical diagrams, and structural load calculations. Inspections verify proper installation: electrical connections, grounding, roof penetration sealing, and NEC compliance. The city follows the International Residential Code and National Electrical Code as adopted. SRP-served properties follow SRP's interconnection process; APS-served properties follow APS procedures. Arizona offers state tax incentives for solar, and federal solar investment tax credits further reduce costs. Ground-mounted solar arrays may have additional setback and structural requirements.
Solar installations without permits may face code enforcement action and must be inspected before utility interconnection. Utilities may refuse to connect unpermitted systems.
