OUR SERVICES
What we build
From rooftop solar to ground-mount arrays to battery storage systems — GEC delivers full EPC services for commercial and industrial clients who need engineering-grade results, not off-the-shelf installations.
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.
GEC's 40+ year MEP/FP engineering background is the foundation of every solar and storage project we build. From structural load analysis to electrical system integration, our licensed P.E.s bring industrial engineering precision to every system we design — because a solar installation is only as good as the engineering behind it.
Proven Results for Energy-Intensive Facilities
For more than 40 years, GEC has helped commercial and industrial clients reduce operating costs through engineering-led energy solutions. Our work spans manufacturing, industrial operations, and commercial facilities where performance, reliability, and long-term savings matter.

The GEC Difference
GEC delivers commercial and industrial solar, battery storage, and engineering solutions through a process built for complex facilities. By combining licensed engineering expertise with end-to-end project delivery, we help clients reduce risk, improve coordination, and build systems designed for long-term performance.
Engineering First
Every project starts with the realities of the facility — structural conditions, electrical infrastructure, load profile, and long-term operational goals.
Designed for C&I
We build for manufacturers, industrial operations, commercial properties, and institutional facilities where reliability and integration matter.
Coordinated End-to-End
From early planning through design, installation, and commissioning, GEC provides a more streamlined process with fewer handoffs and stronger technical oversight.
Incentive & Financing Experts
We evaluate available incentives, utility programs & financing pathways to identify the most practical and cost-effective project structure. Smarter decisions, stronger project economics, and solutions tailored to your goals.
Frequently Asked Questions
Yes. GEC delivers full EPC services — engineering, procurement, and construction — under one roof. Every project is designed by licensed professional engineers, procured through vetted suppliers, and installed by GEC's own team. That single-source approach eliminates the coordination gaps and liability blind spots that come with using separate firms for design and installation, which is especially critical for complex commercial and industrial facilities.
General Energy Corporation has delivered annual savings ranging from $231,000 to over $434,000 for single facilities — including manufacturers, food and beverage operations, and industrial plants across Illinois. Actual savings depend on facility size, energy consumption, and local utility rates, but for energy-intensive C&I operations the impact is substantial and measurable from day one. A site assessment is the most accurate way to project savings for a specific facility.
Illinois commercial solar projects can access several incentive programs including the federal Investment Tax Credit (ITC), accelerated depreciation through MACRS, and the IL Shines Adjustable Block Program, which generates ongoing Renewable Energy Credit (REC) revenue for system owners. GEC has recovered millions in incentives for Illinois clients — identifying and maximizing every available funding source is a built-in part of every project we deliver, not an afterthought.
A typical commercial solar project takes between 6 and 18 months from initial site assessment to system commissioning, depending on system size, permitting requirements, utility interconnection timelines, and site complexity. General Energy Corporation manages the full EPC process under one roof, reducing handoffs and keeping projects on schedule from engineering through final inspection.
Most commercial and industrial facilities have complex structural, electrical, and operational requirements that standard solar installers are not equipped to handle. An engineering-led EPC firm brings licensed professional engineers to every phase — from structural load analysis and electrical system integration to long-term performance design. General Energy Corporation's 40+ year background in MEP/FP engineering means every system is built to the same standard as the facility it serves, reducing risk, improving reliability, and protecting long-term energy value.
