INSTALLER:
Established in 1994, the Aldo Leopold Nature Center (ALNC) connects children with nature while promoting environmental sustainability. ALNC has incorporated renewable energy and energy-efficiency measures into its facilities for decades, including:
In 2023, ALNC began planning its next investment in renewable energy. Legacy Solar Cooperative (LSC) worked with ALNC through 2025 to evaluate its energy use, available incentives and funding, and existing renewable energy systems; coordinate removal and recycling of the solar thermal system; and guide the development and procurement of a new rooftop solar project.
LSC assisted with grant applications, financial analysis, utility data analysis, vendor selection, contract negotiations, and IRS Direct Pay. LSC also provided project oversight and technical assistance through installation, commissioning, and incentive capture.
In 2025, LSC member installer Midwest Solar Power installed a 35.38 kW DC rooftop solar array on ALNC’s preschool building, atop a newly installed metal roof. The array includes 61 Philadelphia Solar 580-watt bifacial modules mounted on south- and west-facing roof sections using IronRidge and EcoFoot racking systems.
The system is projected to produce approximately 43,000 kWh annually, offsetting more than half of ALNC’s annual electricity use.
The project was supported by Renew Wisconsin’s Solar for Good, the Couillard Solar Foundation, and the Hammond Climate Solutions Foundation’s Solar Moonshot program.
