Local Factors
As of January 1, 2026, Arizona law HB2301 mandates instant solar permitting (SolarAPP+) for residential systems in all cities, including areas around Why covered by Pima County. This significantly speeds up the permitting process. Installation labor rates in the Why area are generally competitive, averaging $0.80 to $1.20 per watt. It’s crucial to verify contractor license at the Arizona Registrar of Contractors (ROC) before hiring anyone.
Arizona offers a 25% state tax credit for residential solar installations, capped at $1,000. This credit can be combined with the federal solar tax credit, making solar more affordable. Furthermore, solar equipment is 100% exempt from Arizona’s sales tax and will not increase your property taxes.
Arizona utilities like APS, SRP, and TEP utilize Net Billing (RCP) for crediting homeowners for excess energy sent back to the grid. With net billing, it’s very important to consider battery storage options, particularly to offset peak rates. SRP and APS both impose higher demand charges during peak afternoon hours, especially during the hot summer months. Battery storage allows you to use stored solar energy during these peak times, reducing your reliance on the grid and minimizing demand charges, a strategy known as “peak shaving”.
Weather Impact
Why, Arizona, boasts abundant desert sunshine with over 300 sunny days per year, making it an ideal location for solar panel installations. This high solar irradiance translates to excellent PV yield and significant energy production. However, the intense heat can also impact panel efficiency. It’s essential to choose panels designed to withstand high temperatures and consider proper ventilation during installation to maintain optimal performance. Regular cleaning of solar panels is also recommended to remove dust and debris, maximizing energy production.
