Oceanside 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 / Coastal 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 Oceanside, that means beautiful coastal Mediterranean climate with gentle breezes and reliable sunshine and Oceanside's coastal position and consistent year-round sun create reliable solar production with minimal seasonal variation. 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 Oceanside is backed by our comprehensive 25-year warranty and the knowledge that our team will be here for the long term.
