Solar System Installation

Our NABCEP-certified installers mount 400-watt panels with micro-inverters and fire-code-compliant racking. Each system is engineered for 25-year output and tied into your existing electrical panel. Permits, rebate paperwork, and LADWP inspections are handled end-to-end. Average payback in LA is under six years.

Energy Efficiency

We seal attic bypasses, add R-38 blown insulation, and install low-E windows to drop cooling loads up to 30%. Thermal imaging confirms air leaks before and after work. Rebates through the LADWP Home Energy Improvement Program are submitted for you. Whole-house savings show on the very next bill.

Roofing

Installations use Owens Corning Duration shingles with 130 mph wind rating warranty or standing-seam metal for coastal zones. Tear-off includes new underlayment, drip edge, and ridge vents sized to California Title 24. We match any existing tile profile to keep HOAs happy. All roofs are solar-ready.
