COMPLETE SOLAR SYSTEMS & POWER AND BATTERY STORAGE SYSTEMS

With utility rates climbing across Northern California—from Marin County and Sonoma County to Napa County, Amador, Tuolumne, Alpine, and Calaveras County—going solar is one of the smartest long-term moves a homeowner or business can make. A properly designed solar system lets you generate your own electricity from the sun, dramatically reducing (and in some cases nearly eliminating) monthly power costs. When paired with battery storage, you can store excess production for evening use, peak-rate hours, or outages—essentially creating your own reserve of power instead of relying solely on the grid. Add in available tax incentives and solar becomes a high-value investment that continues paying you back year after year.
Sierra Power Systems designs and installs complete solar and battery storage solutions for residential and light commercial properties throughout the region, including communities like San Rafael, Novato, Santa Rosa, Napa, Jackson, Sonora, Angels Camp, and Arnold. If you’re looking for a dependable path toward real energy independence, our team is ready to help you size, plan, and build a system that fits your goals and your property.

PANEL UPGRADES

Many homes and buildings throughout Northern California—especially across established neighborhoods in Marin, Sonoma, Napa, Calaveras, and nearby counties—were built in the 1940s through the 1970s, and many still rely on outdated electrical panels that were never designed for today’s electrical loads. Modern living demands more power: EV chargers, heat pumps, induction ranges, solar interconnections, battery storage, and home automation all place higher demands on your electrical service and circuitry. If your panel is undersized or aging, it can create nuisance tripping, flickering lights, overheating, and serious safety risks.
Common warning signs include breakers that trip repeatedly, warm or buzzing panel covers, burning odors, dimming when appliances start, or limited space for new circuits. If you’re seeing any of these, Sierra Power Systems can inspect your system and provide a safe upgrade path—whether you’re in San Anselmo, Petaluma, Rohnert Park, Napa, Vallejo, San Andreas, or Murphys. Call today to schedule a panel upgrade consultation and bring your electrical system up to modern, code-compliant standards.

RENEWABLE ENERGY

Tired of watching your electric bill climb every month? If you’re ready to take control of your energy production, Sierra Power Systems helps you understand the full picture—technology, system economics, and proper site selection—so you can make a smart, confident decision. We walk you through the factors that matter most: your usage trends, shading and roof orientation, desired level of offset, future plans (like EV charging or home additions), and how batteries can help you shift usage away from peak-rate hours. Answering these questions correctly is the key to maximizing performance and return on investment.
Whether you’re in Marin County, Sonoma County, Napa County, or foothill communities across Amador, Tuolumne, Alpine, and Calaveras County, our goal is the same: deliver a renewable energy plan that fits your lifestyle and your property. If you’re considering solar, battery storage, or a full energy strategy, contact us to get clear answers and a system design that’s built for long-term value.
