The cost of solar panels in Arizona typically ranges from $2.50 to $3.50 per watt before incentives. For a standard 6 kW residential system, homeowners in Arizona can expect to pay between $15,000 and $21,000 before the federal tax credit.

The average solar payback period in Arizona depends on local electricity rates, available incentives, and sun exposure. Most Arizona homeowners see a payback period between 6 and 10 years. After the payback period, you essentially enjoy free electricity for the remaining 15-20+ years of your system's life. Higher local electricity rates and additional state incentives can shorten the payback period significantly. A qualified Arizona solar installer can calculate your specific payback period based on your energy usage and roof characteristics.
Arizona homeowners who install solar panels typically save between $20,000 and $50,000 over 25 years, depending on system size, electricity rates, and available incentives. These savings come from reduced or eliminated electricity bills, net metering credits, and any applicable SREC income. As electricity rates in Arizona continue to rise (historically averaging 2-3% annually), your savings grow each year. The combination of the 30% federal tax credit and any Arizona-specific incentives helps maximize your return on investment.
The right solar system size for your Arizona home depends on your electricity consumption, roof space, and budget. The average Arizona home uses approximately 10,000-11,000 kWh per year, which typically requires a 6-8 kW solar system. To determine your ideal size, review your annual electricity usage on recent utility bills. Factors like Arizona's average peak sun hours, your roof orientation, and any shading will affect how many panels you need. A professional Arizona solar installer will use satellite imagery and your usage data to recommend the optimal system size.
Yes, solar is generally worth the investment for Arizona homeowners in 2025. With solar panel costs at historic lows, the 30% federal tax credit still available, and electricity rates continuing to rise, the financial case for solar in Arizona is strong. Most Arizona homeowners who go solar see positive returns within 6-10 years, followed by 15-20+ years of significant savings.
