St. David, Arizona is a small rural community in the upper San Pedro River Valley, just southeast of Benson, with a landscape defined by agricultural properties, larger residential lots, mature shade trees, ranches, and broad views toward the Dragoon and Whetstone Mountains. Its combination of open land and established country homes gives St. David a distinctly rural character, and many properties may have additional electrical loads from wells, pumps, workshops, barns, and other equipment. With Southern Arizona’s abundant sunshine and substantial warm-weather cooling needs, residential solar can allow St. David homeowners to generate more of their electricity on-site and reduce the amount of power purchased from the grid.

The primary electricity provider serving St. David is Sulphur Springs Valley Electric Cooperative (SSVEC), the member-owned cooperative that serves much of southeastern Arizona. SSVEC’s residential rates have changed in recent years, including an increase in its standard residential monthly service charge from $40 to $45 effective January 1, 2025—a 12.5% increase in that fixed charge. SSVEC is not an investor-owned utility like APS, TEP, or UniSource, so the large rate-increase proposals currently being considered by the Arizona Corporation Commission for those utilities do not directly apply to St. David’s SSVEC customers. That distinction is important: it would be inaccurate to advertise an APS, TEP, or UniSource proposed percentage increase as a St. David rate hike. Nevertheless, with electricity costs increasing across Arizona, solar can help St. David homeowners reduce grid purchases and gain greater control over their long-term energy expenses.

Adding battery storage can provide another layer of value for St. David homes and rural properties. A battery can capture excess solar electricity produced during sunny daytime hours and make that energy available later in the evening or during other periods when the home would otherwise draw electricity from SSVEC, increasing solar self-consumption and reducing grid dependence. When properly sized and configured for backup, a battery can also keep selected essential loads operating during a power outage—including refrigeration, lighting, communications, gates, and potentially well pumps or other rural equipment when system capacity permits. For St. David homeowners, combining solar panels with battery storage can help manage rising electricity costs while providing greater energy independence and backup-power resilience.
