For Catalina Foothills homeowners, solar panels can reduce the amount of electricity purchased from the utility and provide greater control over long-term energy expenses as electricity rates continue to rise. This is especially valuable for larger homes with substantial air-conditioning, pool, spa, or other electrical loads during Southern Arizona’s long summers. Tucson Electric Power’s updated 2026 rate proposal projects that new rates could increase the average monthly bill for a residential customer with median usage by approximately 11.6%, or $12.92 per month, when the proposed rates take effect. (Tucson Electric Power) A properly designed solar system can offset a significant portion of a home’s daytime consumption, helping reduce dependence on increasingly expensive grid electricity.

Adding battery storage can make solar even more valuable in Catalina Foothills by storing excess daytime production for use later in the afternoon, evening, or during a power outage when configured for backup operation. New TEP solar customers use Time-of-Use or Demand Time-of-Use pricing, with summer on-peak hours currently running from 3 p.m. to 7 p.m., when household cooling demand can remain high even as solar production begins declining. (Tucson Electric Power) A battery can shift stored solar energy into these higher-cost hours, increasing solar self-consumption and reducing reliance on the grid. For Catalina Foothills homeowners concerned about rising electricity costs, pairing solar panels with battery storage can provide lower grid dependence, greater control over long-term energy expenses, and valuable backup-power capability.
