Thern Electric & Solar（Thern Electric INC dba）is a full-service electrical contractor based in Napa, California, founded in 1985. According to the website, its core business covers electrical construction, solar PV, control systems, lighting design, landscape power, and repair and maintenance. Its customers include homeowners, commercial buildings, wineries, agricultural facilities, government projects, architects, and other contractors.
This is not an online software product, but a local engineering and contracting service. Its main capabilities include electrical work for new construction and remodeling, tenant improvements, equipment power supply, main power distribution, control systems, pump station expansion, lighting protection, troubleshooting, code compliance corrections, and multimedia wiring. Typical project scenarios include wineries, wine caves, sports fields, agricultural facilities, landscape lighting, outdoor kitchens, parking lot lighting, and temporary power for events. The company also provides solar PV system installation, backup generator system design, and electric vehicle charging station installation.
The website does not publish a detailed price list. Its service model is primarily project-based quoting, meaning users need to contact the company and describe their project requirements to obtain an estimate. The site mentions “Flat Rate Pricing” for electrical service changes and some basic projects, but no specific amounts are listed, so budget transparency is only moderate.
The advantages are its long operating history, California contractor license, and stated credentials such as California-certified electricians, BBB A+ rating, Bay Area Green Business certification, and safety record. Its service coverage is also broad, spanning design, construction, and maintenance. The drawbacks are that the website feels somewhat outdated, with limited case studies and pricing details, and it lacks online booking, clear warranty information, and response-time commitments. It is also clearly a local Napa/Bay Area service, so its practical value for users in China or other regions is limited.
Best suited for homeowners, commercial spaces, wineries, agricultural facilities, architects, interior designers, and general contractors in Napa and surrounding areas of California—especially projects requiring electrical construction, lighting upgrades, solar installation, or EV charger deployment.
Given its nature, this is a standard U.S. business website and does not indicate any China-specific service. The site is generally likely to be directly accessible, but service delivery depends heavily on local on-site construction. For Chinese users, it is mainly useful as an information reference or as a contact point for cross-border projects.
