Solar Panel Batteries in Tucson
60+ Years of Combined Experience. Free Estimates on Battery Storage.
A solar battery stores the energy your panels produce during the day so you can use it at night, during cloudy stretches, or when monsoon storms knock out the grid. The Solar Store installs solar panel energy storage for homes and businesses throughout Tucson and Southern Arizona, backed by NABCEP-certified installers and a licensed professional engineer with 26 years of experience. Our team carries over 60 years of combined solar industry experience and has been serving local energy needs for more than 22 years.
We work with all inverter companies for battery integration, so we aren’t limited to a single product line or a single type of customer. Whether you’re adding storage to a new system or an existing one, we can build a solution around your actual energy goals.
Free estimates are available for solar battery installation in Tucson and across Southern Arizona. Call (520) 341-2286 or contact us online to get started.
Why Tucson Customers Are Adding Batteries Now
Tucson Electric Power customers with rooftop solar are required to enroll in a Time-of-Use or Demand Time-of-Use rate plan. Under those plans, on-peak rates run from 3–7 p.m. on summer weekdays and during morning and evening windows in winter. A battery lets you discharge stored solar power during those high-cost hours instead of drawing from the grid at peak rates.
Arizona utilities operate under net billing rather than net metering, so excess solar exported to the grid earns a credit below the retail rate. Storing that surplus and self-consuming it avoids the discount entirely. With TEP having filed for a rate increase with new rates proposed for late 2026, the financial case for battery backup is becoming stronger.

For people "starting from zero" this was a huge help to us.
“Katharine - Thanks to you and the team for getting our solar set up promptly and professionally. I don't have enough good things to say about Kevin, the teams who conducted the installations, and your own involvement. All our friends who got solar done (or tried) have horror stories about scams and unprofessional behavior; it put us off from trying this for a while. We were at first relieved and then very happy. Everyone we interacted with was friendly, professional and knowledgeable about the process, technology and government requirements. For people "starting from zero" this was a huge help to us.”- JDC
