Vista deserves a solar contractor that's as committed to this community as the residents themselves. At Option One Solar, we've been serving North San Diego County Inland since 1970 — and in that time, we've learned that every community has its own character, its own challenges, and its own solar potential. For Vista, that means pleasant inland North County climate with warm summers and mild winters and Vista's elevated inland position and longer sunshine hours compared to coastal neighbors make it a strong solar production location. Our team designs systems that are specifically optimized for local conditions, ensuring maximum production and the strongest possible return on your investment. As a licensed C-10 and C-46 contractor with over 2,500 installations completed across Southern California, we bring both the credentials and the track record to earn your trust. Every project we complete in Vista is backed by our comprehensive 25-year warranty and the knowledge that our team will be here for the long term.
