Option One Solar has been serving Southern California communities like Escondido since 1970. While our headquarters is in Apple Valley, our crews, project managers, and service technicians work throughout North San Diego County / Inland every day — and we treat every Escondido customer like a neighbor. When you work with us, you're not getting a call center; you're getting a dedicated team that knows your area. Escondido's inland position gives it more annual sunshine than coastal San Diego, translating to higher solar production and faster payback periods. That's why we take the time to design every system specifically for local conditions — sun angles, utility rate structures, and City of Escondido permitting requirements — rather than applying a one-size-fits-all approach. From a single residential rooftop to a multi-acre commercial installation, our licensed C-10 and C-46 team has the credentials and capacity to deliver. Every project comes backed by our 25-year warranty and ongoing local support.
