On May 21, the community of Edgerton, Wisconsin, came together for a renovation celebration at Edgerton Retirement Apartments (ERA). This event, half a decade in the making, marked both the completion of a construction project and a turning point in how this rural nonprofit cares for its residents and the planet.
With balloons, speeches, and a palpable sense of pride, the event commemorated the energization of a new 44.5-kilowatt solar array—one of many upgrades made possible through an innovative blend of clean energy funding, community partnerships, and a commitment to equity and sustainability.
The celebration drew a crowd of residents, supporters, and clean energy advocates. Among the attendees were Edgerton Mayor Christopher Lund, Paul Schechter, Executive Director of Sunny Side Development; Sam Dunaiski, Executive Director of RENEW Wisconsin; and Cal Couillard, Founder of the Couillard Solar Foundation.
Clean Energy for Comfort and Affordability
Nestled in the heart of Edgerton, ERA is a 24-unit housing complex built in 1983 to serve low-income seniors and people with disabilities. The property keeps rents affordable for low-income individuals, offering a safe, welcoming place to live in community with one another. Originally developed with Rural Development funding on land donated by a local hospital, ERA has long embodied the spirit of community care and resource-sharing.
The vision for transformation began as a way to overcome the challenges of rising energy costs and aging infrastructure. The new rooftop solar installation, installed and energized by Midwest Solar Power on May 21, is mounted on the south-facing roof of ERA’s eastern housing cluster. The 44.5-kilowatt array is expected to produce 54,918 kilowatt-hours annually, covering approximately 39 percent of the building’s total electricity needs.
The solar panels are paired with a new geothermal heat pump HVAC system that will replace the outdated electric resistance heating system. Together, these improvements will significantly reduce energy consumption while shifting most of the electric load to a single meter. The utility savings will be passed directly to ERA’s residents.
Powered by Partnership: Making Solar Possible
The ERA solar project was made possible through a unique mix of grants, tax credit equity, and philanthropic support. The Solar for Good Program, an initiative of the Couillard Solar Foundation administered by RENEW Wisconsin, donated 41 solar panels, roughly half of what was needed, valued at over $9,000.
Sunny Side Development collaborated with long-time property managers Broihahn Management and Consulting to secure additional funding from Rock County HOME, FHLBank Chicago’s Affordable Housing Program, and the USDA Rural Development Program. The project also leveraged tax credit equity, a key tool for bringing clean energy projects to nonprofits and affordable housing developments. These partnerships brought solar within reach for ERA and ensured that the benefits of clean energy would go directly to the people who can most benefit from them.
Beyond Solar: A Holistic Approach to Building Sustainability
The solar installation was just one piece of a comprehensive rehabilitation effort at ERA. All 24 units received health and safety upgrades, enhanced ADA accessibility, and the installation of the new geothermal HVAC system. Together, these changes modernize the property while supporting the long-term sustainability of affordable housing in Edgerton.
Just weeks before the event, a hailstorm had pelted Rock and Dane counties with golf ball-sized ice, damaging roofs across the region. But ERA’s new solar array was unscathed, and the sturdy panels even protected a portion of the roof from more extensive damage—a surprising and welcome side benefit. Project leaders and electricians alike were excited to know that the array will simultaneously decrease residents’ energy bills and shield the covered portion of the roof from inclement weather.
A Model for Energy Justice and Community Care
With the success of the solar installation, Edgerton Retirement Apartments has become a model for how rural communities can be an integral part of the clean energy transition. For nonprofit housing providers, solar is a way to live out their mission of service in a rapidly changing world. For the broader community, it’s a powerful example of what’s possible when compassion and innovation come together. Edgerton Retirement Apartments now shines brighter—not only because of the solar panels on the roof, but because of the community-wide commitment to a cleaner, more equitable future.
