We completed a comprehensive solar and battery storage installation for this residence in Pico Rivera. Our team mounted a 18-panel solar array across the roof and integrated a Tesla Powerwall 3 system to provide reliable whole-site backup. We also performed necessary electrical upgrades, including the installation of a Tesla Backup Switch and a 225A main service panel. The project involved mounting dark solar panels on the existing roof and running external conduit along the stucco walls to connect the system components. This configuration allows the homeowners to maximize self-consumption and maintain power during grid outages.
