CSLB license #977785 authorizes Gecko Solar Energy California in Carlsbad to perform general engineering, general building, and solar contracting under A, B, and C-46 classifications since 2009. Roof-mount and ground-mount PV system designs arrive from in-house engineers, and structural coordination on tile and composite roofs parallels the roofing assessments that Tidal Remodeling performs across North County projects. The C-46 solar classification authorizes grid-tied systems, off-grid arrays, agricultural solar well pumps, and battery-backup configurations under California's NEM 3.0 billing structure. Thermal solar integration for pool and domestic hot-water heating crosses into the plumbing trade, a scope intersection shared with MasterCraft Plumbers on dual-system residential installs. Off-grid system builds spec deep-cycle lithium iron phosphate battery banks rated at 48V with 10 kWh to 40 kWh storage capacity, paired with hybrid inverters supporting both 120V and 240V output for whole-home backup.
