Arizona Solar Installation: Complete 2025 Guide

Arizona stands as one of America's premier solar markets, offering exceptional solar resources, competitive incentives, and year-round sunshine. With electricity rates averaging $0.13-$0.14 per kWh and some of the nation's highest solar irradiance (5.5-6.5 peak sun hours daily), Arizona homeowners enjoy some of the fastest solar payback periods in the country.

Arizona Solar Incentives and Rebates

Federal Solar Tax Credit (30%)

⚠️ URGENT: The federal solar tax credit expires December 31, 2025. The One Big Beautiful Bill (OBBB) signed July 4, 2025 shortened this incentive by 9 years from its original December 31, 2025 expiration. Systems must be installed and operational by year-end to qualify.

Arizona homeowners can claim the federal ITC, providing a 30% tax credit on total installation costs through December 31, 2025. This applies to both solar panels and battery storage systems.

Arizona Residential Solar Tax Credit

Arizona offers an additional state solar tax credit of 25% of installation costs (up to $1,000 maximum). Combined with the federal credit, you can recoup 55% of your investment through tax incentives alone.

Equipment Sales Tax Exemption

Solar equipment purchases in Arizona are exempt from state sales tax (5.6%), saving approximately $1,000-$1,500 on a typical residential system.

Utility Rebate Programs

APS (Arizona Public Service):

• Energy efficiency rebates for solar customers
• Time-of-use rate plans to maximize solar savings
• Battery incentive programs

SRP (Salt River Project):

• SRP M-Power program for residential solar
• Customer generation plans with bill credits
• Energy storage incentive program

TEP (Tucson Electric Power):

• Solar buy-back rates for excess production
• Net metering for qualifying systems

Property Tax Exemption

Solar installations don't increase your property tax assessment in Arizona, despite adding significant value to your home.

Arizona-Specific Considerations

Extreme Heat Performance

Arizona temperatures regularly exceed 110°F, which can reduce panel efficiency by 10-15%. We design systems accounting for this heat derate to ensure you get the production promised.

Monsoon Season Preparation

Arizona's intense monsoon storms (June-September) can bring severe winds and hail. We use reinforced mounting systems rated for 140+ mph winds.

Dust & Soiling

Arizona's dust storms and dry climate mean panels get dirty faster. We educate customers on optimal cleaning schedules and can include automated cleaning systems.

Time-of-Use Rates

Most Arizona utilities use time-of-use pricing, with peak rates from 3-8 PM. Solar production peaks at noon-2 PM, so battery storage can shift production to high-cost evening hours.

Fire Safety

Recent wildfires have led to stricter rapid shutdown requirements. All our systems comply with current NEC code and include module-level shutdown.

SRP: M-Power program allows net billing with credits for excess generation. Customer generation prices locked for 10 years.

TEP: Traditional net metering still available, crediting excess generation at full retail rate. Excellent for solar-only systems.

Solar + Battery Storage in Arizona

Arizona is an ideal market for solar + storage due to:

• High time-of-use rate differentials
• Occasional grid reliability issues
• Monsoon-related outages
• Hot summer nights when solar isn't producing but demand is high

Popular Battery Options:

• Tesla Powerwall (13.5 kWh): $12,000-$14,000 installed
• Enphase IQ Battery (10 kWh): $11,000-$13,000 installed
• LG RESU (16 kWh): $13,000-$15,000 installed

All battery systems qualify for the 30% federal tax credit when installed with solar.
