Haaf Ramp solar panels

Address: 424 S. 4th Street
Number of panels: 160 photovoltaic cells 
Size: 40 kilowatts (kW)
Cost: $251,680 ($90,000 in Solar Rewards rebates)
Annual Savings: $4,200
Completed: March 2012

In March of 2012, one-hundred sixty solar electric panels were installed on the Haaf Parking Ramp in downtown Minneapolis. The solar electric array provides 40 kW of solar electric power, covering about 4 percent of the building’s total electricity needs. The system was installed by Zenergy/West Central Telephone out of Sebeka, Minnesota, and the solar panels were manufactured in the USA by Solar World. On average, the grid-tied system is expected to produce 52,148 kWh of electricity and save $4,200 per year. 

Haaf EV Charging StationThe panels are visible from the top level of the parking ramp, and vehicles can park underneath the support structure that holds the array. The project is one of seven that were installed along the Energy Innovation Corridor on buildings owned by the city of Minneapolis, with funding from the U.S. Department of Energy and the Minnesota Department of Commerce through the American Reinvestment and Recovery Act of 2009. Collectively, the projects will save nearly $900,000 in energy costs over their 30-year lifetimes and prevent 5,550 metric tons of carbon dioxide pollution over the same period.

The parking ramp also has an electric vehicle charging station. This provides a service to those electric vehicle owners who park in the ramp, who can monitor their usage through a free downloadable app.

Operating Savings: This system provides about 4 percent of the building’s annual electricity needs will save the city of Minneapolis an estimated $4,200 in electricity costs per year.

Energy Savings: The 40 kW system will provide about 52,148 kWh of energy annually.

Carbon Savings: Every year this array will prevent twenty six metric tons of carbon dioxide pollution.

Community Economic Benefits: This solar project is one of nine in the Energy Innovation Corridor, made possible by the city of Minneapolis and Federal Stimulus funds. These projects are providing jobs in the local clean energy sector, while helping promote the viability of solar energy production in Minnesota.
