The Milwaukee Public Museum located in downtown Milwaukee (Wisconsin, USA) has gone green by making use of its south-facing façade to produce clean, renewable solar energy. As part of a large restoration project, the museum chose to improve the building’s energy efficiency by replacing the original marble façade with 234 solar photovoltaic panels. The new seven-story façade will generate an estimated 77,000 kWh per year, the equivalent of 442 sixty-watt light bulbs operating eight hours per day, all year round. In addition to this significant saving, the photovoltaic array will serve as an educational experience for the thousands of people that visit the museum each year.
The project, developed by Convergence Energy L.L.C., a company dedicated to providing all-inclusive services in the solar sector, selected photovoltaic inverters manufactured by Ingeteam. The museum is the first building in the city of Milwaukee to have a Building Integrated PV (BIPV) solar wall. In fact, research indicates the array is one of the largest vertical PV walls in the U.S. The installation, with a rated power of 98 kWp (70 kWac), is now in operation after being commissioned on 28 October, 2014.
