Solar Trees at Madison General Office

We continue to learn more about how solar energy works best in the Midwest climate.

Our Madison Solar Demonstration Project has been in service two-and-a-half years, and it continues to generate interest. We’ve given more than 100 group tours. Our dashboard shows real-time generation data and is visited by roughly 2,000 people weekly. Check it out at

Research results are being compiled by our partner, the Electric Power Research Institute (EPRI). They’re joining us in a three-year study of various solar technologies and manufacturers, as well as an energy battery storage system located at our Madison headquarters. EPRI is the leading national research and development group for electric use, generation and delivery.

EPRI reported that the solar systems facing south at a 35-degree angle produce the highest energy. As expected, our dual-axis trackers that can follow the sun produced up to 40% more energy than fixed-tilt solar systems.

In 2016, June produced the most electricity, followed by July and August. In 2017, July led the months in production, closely followed by June, with May coming in third.

An energy-efficient home starts with insulation

Blown in Insulation

Your home’s insulation plays a big role in keeping you cozy year-round. A lack of insulation can be the culprit for uncomfortable summer nights or the reason for extra blankets during cold winter days.

By making sure your home has proper insulation, you can stay comfortable and save  money on your energy bills by reducing your heating and cooling costs. Adding insulation is one of the most cost-effective ways to improve your home efficiency. 
To find out how much insulation your home needs, schedule a Home Energy Assessment through our partner Focus on Energy. During a home assessment, an energy expert will:

  • Inspect your home’s energy use from top to bottom
  • Provide you with ideas on how to save energy

Summer heat can mean high electric bills

High temperatures, more people at home or more days in the billing cycle can all drive bills up.

High temperatures mean your air conditioning has to run at maximum capacity, and for more hours, and that uses more electricity. Even just a few days of extreme temperatures can cause your bill to be much higher. Humidity makes air feel even warmer, so thermostats tend to be set lower. 

Students returning home and family gatherings can also raise energy use. Lastly, check the number of days in the bill cycle. Generally a bill cycle is 28-32 days, but sometimes a bill is for a longer period, which will also raise the total due.
