How It Works
From Consultation to Clean Energy in National City
Our proven four-step process makes going solar in National City straightforward, transparent, and stress-free.
Free National City Solar Consultation
We begin with an honest conversation about your goals and a thorough look at your National City 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 National City
Our engineers combine your site data with the South Bay's reliable coastal 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 & SDG&E Coordination
We manage the entire process: engineering drawings, City of National City building permits, AHJ inspections, and SDG&E interconnection paperwork. Our crew installs your system cleanly and efficiently, typically completing National City 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.
