How It Works
Our Simple Solar Process in Rancho Cucamonga
Going solar in Rancho Cucamonga doesn't have to be complicated. Here's exactly how our process works, from first call to first kilowatt.
Free Rancho Cucamonga Solar Consultation
We begin with an honest conversation about your goals and a thorough look at your Rancho Cucamonga 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 Rancho Cucamonga
Our engineers combine your site data with the Inland Empire's strong foothills solar output 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 Rancho Cucamonga building permits, AHJ inspections, and SCE interconnection paperwork. Our crew installs your system cleanly and efficiently, typically completing Rancho Cucamonga 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.
