COMMERCIAL SOLAR EPC

We design and install rooftop and ground-mount photovoltaic systems for manufacturing plants, industrial facilities, commercial properties, and institutional campuses. Every system is engineered from the ground up for your facility's specific load profile, roof structure, and energy goals — not adapted from a template.

THE GEC DIFFERENCE

Site Analysis & Load Profiling

We analyze consumption, peak demand, infrastructure. Roof/ground conditions. Structural capacity. Utility constraints. This data drives sizing and projections.

Engineering & Design

Licensed P.E.s design in-house. Structural analysis, electrical integration, code compliance. 40 years MEP. Integrates with existing infrastructure.

Permitting & Incentives

Interconnection apps. Building permits. AHJ approvals. We handle it. Plus incentives — IL Shines, ITC, MACRS, utility rebates.

Procurement

Tier 1 equipment. Selected for your site, not what's cheapest. Manufacturer relationships. Supply chain that stays on schedule.

Construction & Commissioning

In-house crews. No subs on critical work. NABCEP-certified. Rigorous testing before handoff.

Monitoring & Maintenance

Real-time monitoring. If output drops, we see it. Ongoing maintenance for the life of the system.
