What is different about solar panel installation in Arizona
Extreme cooling load makes HVAC sizing, duct location and roof reflectivity the highest-leverage decisions in the state; pool permitting also carries mandatory barrier inspection.
Owner-builder: Owner-builder allowed with an ROC exemption affidavit on an owner-occupied home. Solar Panel Installation generally requires a licensed contractor to pull the permit, even where owner-builder status is available.
