The solar energy system at the Ameren St. Louis headquarters is designed to provide practical information about the most popular photovoltaic (PV) solar technologies.

Which photovoltaic system works best in the Midwest?
We compare the most popular three types of solar panels used in our area - side by side. We also integrate tracking system technology that follows the sun. Our goal is to learn the best way to harness solar power in our region.

Visit our Energy Learning Center
Our Energy Learning Center and rooftop viewing area let you see solar technology “up close." Visitors receive detailed information on the cost, efficiency and output of each solar technology. Schools and individuals are welcome to schedule a visit.
