Our Community
Your Fontana Solar Neighbors
When Fontana 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 Inland Empire for over five decades, and we bring that local knowledge to every project we take on in Fontana. Fontana's inland location delivers strong solar output with minimal marine cloud cover that coastal areas experience. We understand the local climate, the SCE rate structure, and the City of Fontana 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 SCE. 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
Your Path to Solar in Fontana, CA
From your first call to the moment your system powers on, here's what to expect when you go solar with Option One Solar in Fontana.
Free Fontana Solar Consultation
We begin with an honest conversation about your goals and a thorough look at your Fontana property. Our team reviews your SCE 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 Fontana
Our engineers combine your site data with the Inland Empire's consistent inland sunshine 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 & SCE Coordination
We manage the entire process: engineering drawings, City of Fontana building permits, AHJ inspections, and SCE interconnection paperwork. Our crew installs your system cleanly and efficiently, typically completing Fontana residential projects within 1 to 3 days.
Activation, Monitoring & Long-Term Support
Once SCE 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.
