Our Community
Rooted in Inland Empire, Serving Corona
Option One Solar has been serving Southern California communities like Corona since 1970. While our headquarters is in Apple Valley, our crews, project managers, and service technicians work throughout Inland Empire every day — and we treat every Corona 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. Corona's position at the western edge of the Inland Empire delivers strong solar production while benefiting from slightly more moderate temperatures. That's why we take the time to design every system specifically for local conditions — sun angles, utility rate structures, and City of Corona 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.
How It Works
Our Simple Solar Process in Corona
Going solar in Corona doesn't have to be complicated. Here's exactly how our process works, from first call to first kilowatt.
Free Site Assessment & Energy Review
We start by reviewing your Corona property and SCE energy bills together. Our team evaluates your roof condition, orientation, and any shading from nearby structures, then combines that with your actual monthly usage — so every recommendation we make is grounded in real data for your specific situation.
Custom System Design for Corona
Using your site data and the Western Inland Empire's reliable sun exposure, our engineers design a system sized and positioned specifically for your property. We model annual production estimates, calculate your payback period, and present a fully transparent proposal with no surprises and no pressure.
Permits, Installation & SCE Interconnection
Our licensed C-10 and C-46 crews handle every detail — pulling permits with City of Corona, scheduling inspections, installing your system to code, and filing your SCE interconnection agreement. You stay informed at every milestone without managing any of it yourself.
System Activation & Ongoing Local Support
Once SCE approves your interconnection, we commission your system and walk you through monitoring your production in real time. Our team remains your local resource for any questions, maintenance, or service needs for the full life of your installation, backed by a 25-year warranty.
