Tron Solar

Tron Solar has built one of the larger residential solar practices in northern Illinois over the past seven years, and the trajectory speaks to a company that has scaled deliberately rather than through call-center sales tactics. Founded in 2018 by Lester Gray and headquartered at 950 Corporate Woods Parkway in Vernon Hills, the company operates as a fully in-house EPC with more than 50 employees and reports over 2,000 residential installations across Chicagoland and the broader Midwest. That self-perform discipline is unusual at this volume tier, and it shows in the 4.8-star Google rating across 1,004 verified reviews our research team confirmed, one of the largest verified review bases of any installer working the Illinois market.

What stood out to our research team is the credential and equipment stack. Tron Solar's design and installation work is handled by NABCEP-certified installers and licensed professionals, and the company holds certified installer status with Enphase, Tesla, Franklin Energy, and QHome battery platforms — the four most important storage credentials a residential customer should look for in 2026. The company also operates an in-house roofing arm, which removes the all-too-common situation in solar where homeowners are caught between a roofer and an installer when a re-deck is needed before panels can be set. A 10-year workmanship warranty covers leaks and anything related to the install itself, layered on top of standard manufacturer panel and inverter coverage.

Independent third-party validation lines up with the in-house messaging. Tron Solar maintains an active EnergySage marketplace profile, a Better Business Bureau listing, and a Focus on Energy Trade Ally designation that confirms participation in regional utility-incentive programs. Prospective customers should still ask pointed questions about subcontractor use on any roofing scope, ComEd interconnection timelines for their specific village or township, and how the company handles change orders if shade analysis reveals issues after the site visit. The fundamentals — Illinois headquarters, NABCEP credentials, multi-platform battery certifications, large verified review base, and self-perform crews — make Tron Solar one of the strongest residential installer profiles our team identified in the state.

With a composite score of 80.5 out of 100, Tron Solar holds the second-ranked position in Illinois for 2026.
