Our Community

Committed to Montclair and Inland Empire

When Montclair 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 Montclair. Montclair's dense residential grid and strong community reinvestment culture make solar adoption straightforward and rewarding. We understand the local climate, the SCE rate structure, and the City of Montclair 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

The Montclair Solar Installation Process

Our streamlined process takes Montclair homeowners from consultation to clean energy in as few as 6-8 weeks.

01

Free Site Assessment & Energy Review

We start by reviewing your Montclair 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.

02

Custom System Design for Montclair

Using your site data and the Inland Empire's reliable solar conditions, 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.

03

Permits, Installation & SCE Interconnection

Our licensed C-10 and C-46 crews handle every detail — pulling permits with City of Montclair, 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.

04

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.
