Tombstone, Arizona is one of southeastern Arizona’s best-known historic communities, famous for its Old West architecture, wooden boardwalks, historic storefronts, mining heritage, and open high-desert setting. Beyond the historic district, Tombstone includes established residential neighborhoods and larger rural properties surrounded by rolling desert terrain and mountain views. The community’s elevation moderates temperatures compared with lower desert cities, but homes still face substantial cooling and other year-round electrical loads. With abundant Arizona sunshine, residential solar can help Tombstone homeowners generate electricity at their property, reduce grid purchases, and gain greater control over long-term energy costs.

The primary electricity provider serving Tombstone is Sulphur Springs Valley Electric Cooperative (SSVEC), the member-owned cooperative serving much of Cochise County. SSVEC has adjusted residential rates 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. Because SSVEC is a cooperative, Tombstone customers are not subject to the current APS, TEP, or UniSource residential rate-increase proposals before the Arizona Corporation Commission, and those proposed percentages should not be represented as Tombstone rate hikes. Those ACC proceedings do, however, highlight the continuing upward pressure on electricity prices elsewhere in Arizona. For Tombstone homeowners, solar can reduce the amount of electricity purchased from SSVEC and provide greater protection from rising long-term utility costs.

Adding battery storage can make a Tombstone solar system even more useful by storing excess solar electricity generated during the day for use in the evening, during higher-demand periods, or when utility power is unavailable. Using more solar energy directly at the property can increase self-consumption and reduce reliance on electricity purchased from SSVEC. When properly sized and configured for backup operation, batteries can also keep selected essential circuits running during an outage, including refrigeration, lighting, internet equipment, communications, and other critical household loads. For Tombstone homeowners, combining solar panels with battery storage provides greater control over grid electricity use while adding valuable backup-power capability and energy resilience.
