We completed a residential renewable energy project in Simi Valley featuring a high-efficiency solar array and a comprehensive battery backup system. Our team installed 13 solar panels on the south-facing roof slope to maximize daily energy capture. The project also included critical electrical service panel upgrades and the integration of a Tesla Backup Switch to ensure seamless power transitions. We utilized the Tesla Powerwall 3 to provide the homeowners with increased grid independence and efficient energy self-consumption metrics. The installation process involved securing professional-grade mounting rails to the asphalt shingle roof and rerouting complex electrical wiring within the main load center. This system now provides sustainable power and reliable backup energy for the entire property.
