Why Arizona Is Perfect for Energy Independence
6.5
Peak Sun Hours/Day
Phoenix metro gets 40% more sun than the national average — your panels produce more power per dollar.
$0.34
APS Peak Rate/kWh
Summer peak rates hit $0.3439/kWh from 4-7pm. Batteries discharge during peak, saving you the most expensive electricity.
$500
VPP Earnings/Year
APS pays you up to $500/year to dispatch your battery during peak grid demand. Your home stays protected.
Virtual Power Plant — The Star Feature
Your battery becomes part of Arizona's clean energy grid. During extreme heat events, APS dispatches stored energy from participating homes instead of firing up expensive peaker plants.
- Earn $150-$500/year from APS grid services
- ~15 dispatch events per year during peak demand
- Battery refills overnight — backup power always available
- $3,750 APS Cool Reward rebate for installation
- 30% federal tax credit on batteries through 2032
Example: 13.5 kWh Battery (Tesla Powerwall 3)
Important: The Solar ITC Expired in 2025
The 30% federal solar tax credit is no longer available for residential installations. However, the battery ITC (30%) remains through 2032 — making battery storage the highest-ROI clean energy investment for Arizona homeowners right now. Our calculators use accurate March 2026 data so you see the real numbers.

Frequently Asked Questions
How much do solar panels cost in Arizona in 2026?
The average cost is $2.50-$3.30 per watt installed. For a typical 8 kW system, that's about $22,800 before incentives. Arizona offers a 25% state tax credit (up to $1,000) and zero sales tax on solar equipment. The federal solar ITC expired in 2025, but the 30% battery ITC remains through 2032.
Is the federal solar tax credit still available?
No. The residential solar Investment Tax Credit (ITC) dropped to 0% in 2026. However, the 30% federal tax credit still applies to standalone battery storage through 2032 — making battery + solar combos the smart play for Arizona homeowners.
What is APS net billing and how much do they pay for exported solar?
APS replaced net metering with net billing using a Resource Comparison Proxy (RCP) rate. In 2026, APS pays just $0.076/kWh for exported solar — while you buy electricity at $0.12-$0.34/kWh depending on time of day. This makes self-consumption and battery storage far more valuable than exporting.
What is a Virtual Power Plant (VPP) and how much can I earn?
A VPP is a network of home batteries that APS can dispatch during peak grid demand instead of firing up expensive peaker plants. APS pays participating homeowners $150-$500/year through the Cool Reward program, with about 15 dispatch events per year. Your battery refills overnight so backup power is always available.
What's the payback period for solar panels in Arizona?
Without the federal credit, solar-only payback runs 9-14 years. Solar + battery payback is 8-11 years thanks to peak arbitrage savings and the 30% battery ITC. A battery alone with the APS rebate can pay back in as little as 4-5 years when you factor in VPP earnings and TOU arbitrage.
Are your calculators free?
Yes, completely free. Our solar and battery calculators use real APS TOU rates and NREL PVWatts solar production data for your specific location. No sales pitch, no lead generation — just accurate math to help you make informed decisions.
