Solar and backup across Arizona

Power your property independently

Reliable power, across Arizona. We design new solar, whole-property battery and generator backup, and battery retrofits for existing arrays. Solar does not have to come first.

What We Do

Solar now, backup first, or a retrofit

Statewide in Arizona. Choose a new array, whole-property backup without solar, or a battery on solar that only backfeeds today.

Off-grid solar

A new array sized from your bill, your roof, and the loads you want to run.

Whole-property backup

Battery and generator backup for the property, even if you are not adding solar yet.

Solar retrofit

Turn a backfeed-only solar system into one that keeps running on a battery.

Design and install

Site visit, equipment, permitting support, and a tested handoff.
