About Solar Installation Group, Inc.

This strong reputation reflects consistent performance in residential solar panel and battery installations throughout the local community. The company operates Monday through Friday from 8 AM to 4:30 PM, providing standard solar services to homeowners seeking to reduce their reliance on traditional utility power.
What distinguishes this contractor is their meticulous attention to homeowner preferences.

One reviewer described a same-day installation completed in approximately 10 hours, covering 23 panels, one battery, an inverter, and a smart electrical panel. The crews performed thorough cleanup, with reviewers noting no debris, packaging, or hardware left behind after the installation.
