Why More Arizona Homeowners Are Pairing Solar With Batteries
More homeowners are considering solar and battery storage together. An October 3, 2026 pv magazine report, citing Lawrence Berkeley National Laboratory’s 2026 data update, found that batteries accompanied 37% of new U.S. residential solar installations in 2025, up from 25% in 2024. Arizona was among the states with particularly strong growth. These are national historical results, not an Arizona-specific adoption percentage or a savings forecast.
Why the pairing matters
Solar produces electricity when sunlight is available. A compatible battery can store some of that energy for later use. For an Arizona household, the questions are practical: What happens during an outage? How much electricity do we buy during higher-cost hours? How does our current utility plan value exported solar?
Backup protection and everyday energy management
A properly designed battery system can support selected household loads during an outage. Daily operating settings may also shift grid purchases away from higher-cost periods or increase use of your own solar generation. Backup duration and potential savings depend on actual usage, equipment, charging costs and losses, utility rates and system settings. Maintaining an outage reserve can reduce the energy available for daily bill management.
Start with your APS, SRP or other utility plan
Have a qualified installer review your actual bills and current rate plan. Ask for a comparison that includes installed cost, charging losses, any applicable demand charges, export compensation, warranty terms and financing costs. A battery does not guarantee a lower total bill or eliminate future utility rate increases.
Already have solar?
Confirm inverter compatibility, electrical upgrades and whether the proposed setup can recharge from solar during an outage. Ordinary grid-connected solar does not automatically keep a home powered when the grid is down.

October 6 update: Your battery can have a job every day
A Reuters analysis published October 6 describes how renewable generation helped meet summer electricity demand, with battery storage extending solar energy into evening hours. Those grid-level results are a useful reminder of energy timing; they do not predict savings for an individual Arizona home.
For your home, compare two jobs: keeping selected loads running during an outage, and shifting electricity purchases on ordinary days. Ask an installer to model your current APS, SRP or other utility plan using your actual bills. Include charging losses, export credits, installed cost and the capacity reserved for outages. More daily use can leave less energy available for backup unless your reserve settings account for it.
