Is solar worth it in Arizona in 2026?
With an average electricity rate of 13.2¢ per kWh and 6.5 peak sun hours per day, Arizona homeowners are in an excellent position to benefit from solar panels. A typical 10kW system will produce around 18,980 kWh per year — enough to offset a significant portion of a typical Arizona home's electricity usage.
At current electricity rates, that production saves approximately $2,505 per year. Over 25 years — the standard panel warranty period — the projected net profit after recouping the system cost is around $41,625.
How much do solar panels cost in Arizona?
A 10kW solar system — typical for a Arizona home — costs approximately $30,000 before incentives (national average: ~$3,000 per kW installed).

What affects solar savings in Arizona?
Every homeowner's solar savings are different. In Arizona, the key variables are:
- Electricity rate (13.2¢/kWh): Arizona's electricity rate is near the national average. Combined with sun hours and system size, this gives a typical homeowner a solid case for solar investment.
- Peak sun hours (6.5 hrs/day): Arizona has excellent solar irradiance. High sun hours mean your panels will produce more energy per kW of installed capacity than most of the country.
- System size (10kW typical): The right size depends on your electricity bill. A $150/month bill typically requires a 6–8kW system to offset 80–100%. Use our System Size Calculator to find your exact target.
- Roof type and orientation: South-facing roofs at 30° pitch are ideal. West-facing roofs produce 15–20% less but may generate more electricity during peak-price afternoon hours, improving time-of-use savings.
