We completed a comprehensive residential energy upgrade in El Segundo, featuring the installation of a 20-panel solar system. Our team carefully mapped the existing roof planes and integrated the arrays with a Tesla Powerwall 3 backup unit. We used Hyundai Energy Solutions panels mounted on durable grey asphalt shingles to maximize efficiency and longevity. The final configuration included a full electrical integration to ensure seamless backup power for the home during grid outages. This system provides the homeowner with long-term energy independence and reliable whole-home protection.
