Solar 101


Discover the benefits of going solar:

  • Reduce your emissions to help the environment.

  • When your solar generation system doesn’t produce all the electricity you use, Rock Energy will keep the power flowing to your home.

  • Receive credits on your bill when you produce more energy than you use.

  • While Illinois & Wisconsin are not known for being the sunniest states, solar still works.
