The state of the art Sun Prairie West High School is truly a building of the future with a ballasted roof solar array. The racking system requires no mechanical attachments to the roof, which means minimal roof penetrations. 712 Heliene 400 watt solar modules cover two roof areas. Three SolarEdge inverters, located in the electrical room, feed solar generated energy directly into the schools electrical system.

A 140 kW ballasted solar array was completed at Baraboo High School in 2022. The solar array offsets electrical usage by the high school and provides real-time production information that shows students the value of renewable energy.

Madison West removed two older systems – a solar electric and a solar hot water system – to make room for a new 124 kW ballasted solar array. Conduit installation was tricky and required routing through several maintenance closets to the electrical room.
