Lotta Electric Inc. in Santee is a third-generation electrical contractor holding CSLB License #746422 (C-10 Electrical) alongside additional general building and flooring classifications under the Lotta Construction umbrella. Grid-tied and off-grid photovoltaic array installations coordinate with solar construction firms including Sun Diego Solar Construction LLC on Hartley Road, where Lotta's C-10 scope covers inverter wiring, rapid-shutdown device installation per NEC 690.12, and utility interconnection metering. The company's renewable energy focus extends to Level 2 and DC fast-charging EV station installations for residential garages and commercial parking structures, plus electrical system upgrades that bring aging panels into compliance with current California Electrical Code requirements. Roof-mount solar projects require pre-installation coordination with roofing contractors such as Top Flight Roofing on Cuyamaca Street to verify structural attachment points, waterproof conduit penetrations, and flashing details before array racking is anchored. The firm's largest residential installations include 50-panel rooftop arrays with Enphase IQ7X microinverter strings and 200-amp main service panel upgrades to accommodate combined solar production and EV charging loads.
