In the blistering Yuma Desert heat, a Somerton homeowner's summer electric bill from Arizona Public Service (APS) can be staggering. Rooftop solar is the most effective way to fight back. In 2026, the essential question isn't just about getting solar panels—it's about pairing them with a battery to gain true energy independence from APS and its complex rate structures.
Benchmark Cost Analysis
Solar & Battery Pricing in Somerton for 2026
A properly sized solar and battery system designed to maximize your savings with APS costs approximately $23,500 before any incentives. This is the realistic starting point for an investment that truly protects you from utility rate hikes. While a solar-only setup looks cheaper on paper (around $11,500), it's a poor fit for APS's net billing rules and won't deliver the expected financial return.
After applying all available tax credits, the net investment for a complete system is about $15,450. This price gives you control over your power and sets you up for long-term savings.
Incentives & Tax Credits
Available Tax Credits for Somerton Residents
Federal and state incentives significantly lower the barrier to entry for solar. Here's the breakdown:
- 30% Federal ITC: This tax credit deducts 30% of the system's total cost from what you owe in federal taxes. On a $23,500 system, that's a $7,050 credit.
- $1,000 Arizona State Credit: Arizona offers its residents a tax credit of up to $1,000 for installing solar.
- Tax Exemptions: You will not pay any sales tax on your system, nor will your property taxes increase because of the value it adds to your home.
These powerful incentives are designed to encourage energy independence and make systems affordable for homeowners.

Net Billing (2024)
Critical 🔋
Why a Battery is Non-Negotiable with APS Net Billing
Arizona Public Service (APS) operates on a 'Net Billing' system. This means any excess solar power you export to the grid is credited at a low wholesale rate (the Resource Comparison Proxy rate), which is far less than the retail rate you pay for electricity. Without a battery, you are forced to sell your valuable solar energy to APS for pennies and buy it back for dimes just a few hours later. A battery solves this problem by storing your excess solar power, letting you use it yourself at night and completely bypassing APS's unfavorable export rates.
Projected Savings
Your Expected Savings with Solar + Battery
Your average APS bill is around $140 per month, but that skyrockets in the summer. A solar and battery system slashes this by allowing you to power your home with your own clean energy, especially during expensive on-peak hours. First-year savings are estimated at $915, with a typical payback period of around 17 years. This payback period shortens every time APS raises its electricity rates, making your investment more valuable over time.
