Kolbe Windows & Doors recently completed and activated a solar panel system on the roof of its main manufacturing facility in Wausau, Wisconsin. This 999.6-kW array consists of 2,061 photovoltaic panels and is expected to offset 31.8% of the window manufacturer’s current energy consumption at the plant.

Kolbe worked closely with Northwind Solar, a PV contractor from Amherst, on the design and installation of the system. The array uses bifacial modules that will of the panels that will caputure additional sunlight reflected through the underside of the panel. The installation began in 2024 and was partially funded by a USDA Rural Development grant as part of the Rural Energy for America Program (REAP).
“We are thrilled to be utilizing the unused space on the roof of our facility for something so impactful: Increasing our operational efficiencies and reducing our carbon footprint,” said Jeff DeLonay, president of Kolbe Windows & Doors. “This project represents a major part of our efforts to better serving our team, our community and our environment.”
Additionally, in 2022, Kolbe installed a smaller 19.72-kW, 58-panel solar project on the roof of its Innovation Greenhouse, also located in Wausau.
Kolbe’s commitment to energy efficiency extends beyond the solar panel system. The company has implemented several initiatives, including the installation of timer-controlled LED high bay lights, an optimized humidification system and air make-up units to enhance energy efficiency.
