Solar: Illinois

Compare Electricity has developed a solar score for Illinois to help residents and businesses determine if a solar installation is a viable and cost-effective solution. The solar score is based on a combination of many different factors. Illinois is slightly below the national average in solar viability. The northwest part of the state receives between 4-4.5 kWh of direct sunlight per square mile per day which is slightly below the national average. The southeast part of the state receives 4.5-5 kWh of direct sunlight. An estimated 71% of Illinois roofs are viable for solar installation and are unobstructed from direct sunlight. If all these home installed solar panels there would be an estimated savings of over 50 million metric tons of carbon emissions in Illinois. Due to all these factors, a residential solar installation is generally a viable option for Illinois residents. See the solar score graph below for more information.

Illinois Solar Score: 33

Compare Electricity has developed a solar score for Illinois residents and businesses of 33/100. The score is based on on a combination of factors including how much sun the area receives, roof space and obstacles that may obstruct the sun, electricity generation needed to be cost-effective, and more. Here is a description of each section of the solar score graph:

    • Red = “Not Viable” meaning a solar installation would not be cost-effective.
    • Yellow = “Viable” meaning a solar installation would pay for itself over time.
    • Green = “Very Viable” meaning a solar installation would pay for itself quickly and has large savings potential.
