American Family Insurance

Rooftop | 1.2MW


American Family Insurance American Family Insurance, a multi-line insurer headquartered in Madison, Wisconsin and a Fortune 500 company, partnered with SunPeak to build the largest rooftop solar system in the state of Wisconsin at its national headquarters.

The almost 1.2MW solar photovoltaic system covers a large rooftop on the corporate campus with 4,488 solar panels.

This system now generates over 7% of their energy needs and is projected to produce $5.6 million in energy savings over 30 years.

Reduced Electricity Costs

With a former utility blended cost of electricity of 8.5¢ / kWh, this system reduces their levelized cost of energy over the life of the system to about 3.7¢ / kWh. The system will produce over $119,000 of direct energy cost savings per year. As the cost of electricity increases over time due to inflation, these energy savings will grow over time.
