Wisconsin sock maker adds solar hot water.

No greenwashing here.

Also, Wisconsin's Focus on Energy published a case study of the installation for other manufacturing plants to study and learn from.
They concluded that we are a new breed of solar contractor -- since we use both engineering and licensed contracting.


Innovation in design.

Our answer? Drainback. This became the first commercial drainback system of its size in the Midwest -- and quite possibly the US.
