Solar power for commercial buildings has crossed the line from forward-thinking to financially obvious. Kohl Electrical Services designs and installs commercial solar power systems for businesses, property owners, and facility operators across the greater Milwaukee area — delivering systems that reduce energy costs, qualify for available incentives, and are installed to the standard your building deserves.
The case for commercial solar in Wisconsin is straightforward. Energy costs are rising, federal and state incentives remain significant, and the technology has matured to the point where a well-designed commercial solar system delivers predictable, measurable returns for the life of the building. The variable isn't whether solar makes sense — it's whether the installation is done right.
Kohl Electrical Services handles the full electrical scope of commercial solar installation — system design coordination, inverter and electrical balance-of-system installation, utility interconnection, metering, and all electrical work from the array to the building's distribution system. We work with commercial property owners, owner-occupants, and developers on rooftop solar installations for warehouses, office buildings, manufacturing facilities, retail centers, and multi-tenant commercial properties.
We approach solar the same way we approach every electrical project — with a focus on doing the work correctly, coordinating all the moving pieces, and delivering a system that performs as specified for the long term. We handle the electrical side with precision so the system your solar developer designs actually gets built the way it was intended.
A solar installation is a long-term investment. The quality of the electrical work behind it determines whether that investment performs as promised for 25 years or creates maintenance headaches from day one. Here's what we bring to every commercial solar project.
Getting a commercial solar system connected to the utility grid is one of the more complex parts of the project — and one of the most important. We handle the full utility interconnection scope, including all required electrical work, metering configuration, and coordination with your utility provider to ensure the interconnection process moves efficiently and the system is energized on schedule.
Every component of a commercial solar electrical installation — inverters, combiners, disconnects, conduit runs, metering, and the connection to your building's distribution system — must meet Wisconsin electrical code and relevant NEC requirements. We know those requirements and install to them, which means your system passes inspection and operates safely for the life of the installation.
A solar installation doesn't exist in isolation — it connects to your building's existing electrical infrastructure. We assess that infrastructure before the project starts, identify any upgrades needed to support the solar system, and coordinate the solar installation with your building's existing electrical systems so everything works together correctly from day one.

Common questions from commercial property owners and facility managers considering solar power in the Milwaukee area.
Yes — Wisconsin's solar resource is better than most people expect, and the financial case for commercial solar is strong when you factor in current federal investment tax credits, available utility incentives, net metering policies, and the long-term reduction in energy costs. A properly designed and installed commercial solar system typically delivers a payback period of five to eight years and meaningful energy cost reduction for 25+ years after that.
The federal Investment Tax Credit currently allows commercial property owners to deduct a significant percentage of solar installation costs from federal taxes. Wisconsin also has utility-specific incentive programs and net metering policies that improve the financial return. The incentive landscape changes over time, so we recommend discussing current available incentives as part of your project evaluation.
We handle the full electrical scope of the installation — system design coordination, inverter and balance-of-system installation, utility interconnection, metering, all conduit and wiring from the array to your distribution system, and inspection and commissioning. Panel and racking installation is typically handled by the solar developer or a roofing contractor — we coordinate closely with them to ensure the electrical work integrates correctly with the mounting system.
Timeline varies based on system size and project complexity. The electrical installation itself on a typical commercial rooftop system takes one to three weeks. The longer timeline items are typically utility interconnection approval and equipment lead times — both of which we factor into the project schedule from the start and manage proactively.
