Arch Solar and SolarEdge have announced new solar portfolios with two Wisconsin cities: Edgerton and Wauwatosa.
While Edgerton opted for an all-in portfolio installation of five buildings, completed in spring 2025, Wauwatosa is taking a phased approach, with the most recent implementation at the Police Department.
In Edgerton, city leaders pursued an ambitious goal: installing solar power in five municipal buildings in one coordinated effort. The city now offsets 64% of its municipal energy consumption, reducing carbon emissions while maintaining crucial city services. The 82.4 kWdirect current The rooftop solar portfolio includes the city hall, the DPW garage, the police department, the library and the water building.
“The City of Edgerton leadership has made a strategic commitment to invest federal ARPA funding in energy conservation initiatives,” said Ramona Flanigan, City of Edgerton Administrator. “A significant portion of this funding was spent on five solar installations, which will not only reduce energy costs, but also reduce carbon emissions. This forward-thinking approach will deliver lasting benefits to our residents and the environment for decades.”
Meanwhile, the City of Wauwatosa has been working with Arch Solar on municipal solar installations since 2021, gradually building clean energy capacity at City Hall, the Library, the Department of Public Works, the Fire Department and EV charging infrastructure. The latest 365 kWdirect current project at the Wauwatosa Police Department combines rooftop and ground-mounted arrays using SolarEdge SE50K-US residential content inverters.
“The Wauwatosa Common Council has adopted an energy resolution requiring at least 25% of all energy used for municipal operations to come from local renewable sources,” said David Simpson, PE, Public Works Director for the City of Wauwatosa. “The solar projects we pursued have helped us reach nearly half of that goal in just a few years. We recognize that how we operate today determines Wauwatosa’s future, which is why we are embracing sustainable practices as we continue to upgrade the city’s infrastructure.”
