Private Napa Foothill Retreat with Energy Independence and Net-Zero Electricity Costs! With a new roof in 2026, full exterior repaint, and a proven history of near net-zero electric costs, this private 20-acre Napa foothill property offers an uncommon combination of beauty, resilience, and long-term efficiency. The single-story Craftsman residence features 3 bedrooms, 2 bathrooms, and approximately 1,913 square feet of thoughtfully designed living space. Hardwood floors, Vermont soapstone counters, maple cabinetry, and a Rumford fireplace create a warm, comfortable interior, while French doors in the kitchen and primary suite open to quiet foothill views. Designed for dependable day-to-day living, the home includes a 28-panel solar array paired with Tesla’s latest Powerwall 3 batteries, EV charging capability, and a 14-kW whole-house backup generator. Since 2022, solar production has offset annual electricity usage, including EV charging, while supporting reliable backup power during outages. The system also benefits from transferable NEM 2.0 status, allowing a future owner to continue receiving favorable utility credits. Water is supplied by a shared spring with 5,000 gallons of on-site storage and whole-house filtration. Dual-zone HVAC enhances year-round comfort. Approximately 13 of the 20 acres are fenced, offering controlled, usable land without the need for additional infrastructure. A detached workshop and two separately fenced enclosures adjacent to the home offer practical utility for pets, gardening, or other pursuits. A rare blend of Napa foothill privacy, practical infrastructure, and materially reduced operating costs well suited for full-time living or as a refined second-home retreat.
