Our Community
Rooted in San Diego Metro, Serving San Diego
When San Diego homeowners and business owners choose solar, they deserve a contractor who understands their community — not a national franchise operating from a call center three states away. Option One Solar has served San Diego Metro for over five decades, and we bring that local knowledge to every project we take on in San Diego. San Diego's combination of near-perfect solar weather and California's highest utility rates makes it one of the strongest solar ROI markets in the country. We understand the local climate, the SDG&E rate structure, and the City of San Diego permitting process — all of which directly impact how we design and install your system. That local expertise means fewer surprises, smoother permitting, and a system that performs as promised. Our C-10 and C-46 licensed team handles every phase of your project, from initial consultation through design, installation, and interconnection with SDG&E. And because we stand behind every installation with a 25-year warranty, we're always just a call away when you need us.
How It Works
Our Simple Solar Process in San Diego
Going solar in San Diego doesn't have to be complicated. Here's exactly how our process works, from first call to first kilowatt.
Free San Diego Solar Consultation
We begin with an honest conversation about your goals and a thorough look at your San Diego property. Our team reviews your SDG&E bills, evaluates your roof and site conditions, and identifies any shading or structural factors that affect system design — before recommending a single product.
System Design Optimized for San Diego
Our engineers combine your site data with San Diego's legendary near-perfect Mediterranean climate to create a custom production model for your specific property. You receive a clear proposal showing system size, estimated annual output, projected savings, and full payback timeline — all with transparent pricing from the start.
Installation, Permits & SDG&E Coordination
We manage the entire process: engineering drawings, City of San Diego building permits, AHJ inspections, and SDG&E interconnection paperwork. Our crew installs your system cleanly and efficiently, typically completing San Diego residential projects within 1 to 3 days.
Activation, Monitoring & Long-Term Support
Once SDG&E approves your system to operate, we activate it and walk you through your monitoring dashboard so you can track production from day one. Our team is always reachable for maintenance, service, or questions — and every installation is backed by our 25-year warranty.
