The Aldo Leopold Nature Center (ALNC) uses a combination of photovoltaic, active, and passive solar technologies to provide electricity and temperature control for the building.

In 2025, a new 38.38 kW grid-connected photovoltaic system was installed to expand on-site renewable energy production.The roof-mounted array is attached to south- and west-facing roof sections using an IronRidge and EcoFoot racking system and is projected to produce approximately 43,000 kWh of electricity in its first year, offsetting more than half of the facility’s annual electricity use.

The system includes 61 Philadelphia Solar 580-watt bifacial modules. The project began in 2023 with guidance from Legacy Solar Cooperative, who assisted with permitting, grants, and coordination. Installation was completed by Midwest Solar Power.

Support for the project included donated panels through Renew Wisconsin’s Solar for Good program, funding from the Couillard Solar Foundation, and a grant from the Hammond Climate Solutions Foundation’s Solar Moonshot program.

2010 Madison Gas & Electric Solar Energy Photovoltaic System:
This 17.172 kW Solar Array, manufactured by Sunpower and installed by H&H Solar Energy Services, features 54 modules in three rows. The panels are angled for best efficiency and produce 17.172 kW of electricity at peak, and an estimated annual energy production of 20,918 kW hours per year. The PV system is connected to MGE’s energy grid and generates energy for MGE customers.
