Sun Diego Solar Construction LLC in Santee holds CSLB License #1016182 and has designed residential and commercial photovoltaic systems across San Diego County since 2007. Each grid-tied array requires an electrical panel upgrade to accommodate new solar loads, a wiring scope that often runs in parallel with contractors such as Keil Electric on Magnolia Avenue. Formerly operating as Cheatham Solar Construction, the company carries NeoVolta Certified Installer and Sonnen Certified credentials and pairs modules from Silfab Solar and AXITEC with Chilicon Power microinverters. Battery backup integration using NeoVolta, Franklin WH, Fortress, and Generac storage units allows Santee homeowners to offset peak SDG&E demand charges, the same time-of-use calculus that drives efficiency upgrades at firms like Allegiance Heating & Air Conditioning. Highest-capacity projects combine rooftop photovoltaic arrays with paired battery walls and Level 2 EV charging stations, delivering integrated energy systems that can offset a household's full electrical demand.
