Illinois residents experience an average of 198 sunny days a year, just under the national average of 205 days.* With so much sunshine as a resource, solar energy is vital to Illinois' future, as evidenced by the state's renewable portfolio standard that requires Illinois to generate at least 25% of its energy from clean sources by 2025.* With over 48,225 solar installations and a total solar investment of $1.4 billion, Illinois' commitment to solar energy is clear.

How much does solar cost in Illinois?

The cost of a home solar system can vary due to a range of factors, even in the same state. These include:

  • The angle of the roof

  • Roof space

  • Quality of the solar panels

In Illinois, we found that the cost of owning a 5 kW solar system ranges from $12,950 to $23,150, or, in other words, from $2.59 to $4.63 per watt, and that's before considering the benefits of any available tax credits or incentives.

Statewide financial incentives allow Illinois residents to save money on the price of their solar installations and other associated costs.

  • First, Illinois Solar For All programs reduce the costs of solar installations for income-eligible households.* These programs match eligible homeowners with approved solar vendors who offer services for no or minimal upfront costs.

  • Illinois also participates in net metering, which is a program that allows homeowners who generate solar energy to sell back unused power to their local utility companies.* Through Illinois's net metering program, homeowners can receive a one-to-one retail rate credit for any excess solar generation.

  • Tax breaks also make the price of going solar in Illinois more affordable. For example, the Special Assessment for Solar Energy Systems* prevents homeowners from paying higher local property taxes if their solar installations increase their home's value.

  • Finally, Illinois residents can take advantage of the federal investment tax credit, which provides an income tax savings of 30% of the total installation costs.*
