Top Contractors in Washington
Clean Energy Innovators
📍 Seattle, WA
Clean Energy Innovators is a locally owned, engineering-led energy company serving Seattle and Western Washington. The company specializes in designing battery-first backup systems tailored to each home's electrical infrastructure, outage priorities, and desired runtime. Their services include permanently installed home battery backup systems that auto-activate during outages, solar and battery hybrid systems featuring bifacial panels and smart load control, generator and battery integration using Generac PWRcell technology for multi-week outage resilience, and whole-home versus partial backup configurations. Every consultation begins with a master's-level electrical engineer rather than a salesperson, and clients work with the same technical team from initial design through installation, commissioning, and long-term support. The company intentionally limits the number of projects it takes on to ensure each receives focused engineering attention, with all system modeling done in-house. Clean Energy Innovators serves Western Washington homeowners, including customers in Seattle and surrounding areas such as Olympia. They also offer an eight-chapter Battery Learning Center on their website, covering battery basics, backup strategies, time-of-use bill savings, off-grid living, portable versus permanent battery backup, and what to expect during installation. Solar recharge and generator support can be integrated into any system where they add meaningful value. Customers can request an engineering consultation by phone at 206-965-8666 or through the company's website.
