Milholland Electric began operations in San Diego in 1990 as an electrical contracting firm before expanding into solar installation and roofing services. Operating as SunPower by Milholland Electric, the company built its reputation around integrated services across three core areas: solar panel installation, roofing solutions, and electrical contracting for residential and commercial properties throughout San Diego and Orange County. The company became a SunPower Master Dealer and achieved certifications including Tesla Powerwall Certified Installer status and NABCEP certification. According to company materials, Milholland completed over 7,000 residential solar projects across Southern California during its years of operation. The business emphasized whole-home energy solutions, combining premium SunPower solar panels with energy storage options and comprehensive roofing services under one contractor license. Milholland Electric was veteran-owned and promoted its three-in-one service model, where a single team handled solar installation, electrical work, and roof preparation or repair. This integrated approach aimed to simplify the solar installation process for San Diego homeowners who might otherwise coordinate between separate contractors. The company focused particularly on SunPower’s high-efficiency Maxeon solar cells and offered Tesla Powerwall battery storage systems for backup power and energy independence. In January 2020, Solar Integrated Roofing Corp. (SIRC) acquired Milholland Electric as part of a broader consolidation strategy in the California solar market. The company continued operations under SIRC ownership for several years. In April 2024, SIRC divested its residential solar assets, and Milholland Electric was sold to an undisclosed buyer as part of that transaction. Prospective customers should verify the company’s current operational status, ownership structure, and ability to service warranties before engaging. As with any solar installer, California homeowners are encouraged to confirm active licensing through the Contractors State License Board, request multiple quotes, and review recent customer feedback to ensure the company can deliver on commitments and provide long-term system support.
