Commercial Solar in Arizona in 2026
Arizona averages 6.0+ peak sun hours daily in the Phoenix metro — among the highest of any major commercial solar market in the US. The state's 10% corporate tax credit for commercial solar stacks directly on top of the federal ITC, creating a potential 40-60% combined credit for qualifying projects. Property and sales tax exemptions further reduce effective project cost. APS serves most of the Phoenix metro and rural Arizona, while SRP (Salt River Project) serves the East Valley including Tempe, Mesa, Chandler, Gilbert, and Scottsdale. TEP (Tucson Electric Power) serves the Tucson metro. Our Arizona partners are active across the Phoenix metro and Tucson market. See Arizona Commerce Authority renewable energy programs for state-level guidance.

The SolarEdge Safe Harbor: Arizona ITC Access Through 2030
The federal construction-start safe harbor deadline (July 4, 2026) has passed, and most developers are now racing to place projects in service by December 31, 2027 — the standard cutoff — or risk losing the ITC entirely. Our select installer network isn't on that clock. Through a pre-negotiated, physically verified equipment reservation with SolarEdge, our partners secured safe-harbored access to the federal Investment Tax Credit for qualifying Arizona projects completed by December 31, 2030 — a three-year extension unavailable to developers outside this network.
Deloitte independently reviewed the strategy: its team toured SolarEdge's manufacturing facility, met with SolarEdge leadership in Tampa, FL, and issued a memo confirming that projects built on this reserved-inverter methodology qualify for ITC treatment. SolarEdge has committed gigawatt-scale production capacity to this arrangement, with roughly 200 MW currently allocated to partner networks nationwide. Fewer than 10 installer networks in the US hold a direct reservation of this kind.

How to Get Started With Arizona Commercial Solar
The fastest path to locking in incentives is requesting a proposal now. Our team verifies ITC eligibility, checks energy community adder status, identifies applicable state programs, and connects you with a vetted Arizona EPC. The December 31, 2027 ITC in-service deadline makes timeline certainty critical — starting the proposal and interconnection process now is essential.
