Carlsbad Solar holds CSLB license #1023872 and operates from Highland Drive in the 92008 zip code, focusing exclusively on new photovoltaic systems paired with battery storage. Roof-load engineering for panel mounting requires structural assessments that dovetail with the prep work Roofing101 performs before rack installation on Carlsbad's coastal-exposure rooflines. The company does not service pool-solar systems or add panels to existing arrays, concentrating instead on ground-up residential installs with integrated lithium-ion or LFP battery banks. Whole-home energy audits that factor in HVAC load — a calculation that intersects with the system-sizing work at Surfside Heating & Air Conditioning — determine optimal panel count and inverter capacity. Typical high-value installations include 10-to-15-kW rooftop arrays with dual battery units configured for time-of-use rate arbitrage under SDG&E's NEM 3.0 tariff structure.
