Best solar companies in Illinois

Best brands of solar panels

To find the best brands of solar panels you can use America's most trusted solar panel comparison and reviews website, SolarReviews.

However, reviews of solar panels can be a bit meaningless because most consumer owners have not had any issues and so whilst solar company reviews are very important when choosing solar installers they are of less use when choosing solar panels.

What rebates, solar tax credits and other solar incentives are available in Illinois?

Unfortanely there is no state level tax credit or rebate however, a bill has just passed that introduces and RPS and solar carve out meaning that all utilities in state must source a percentage of energy from solar which creates an SREC market. A typical 5kW system in Illinois will produce about 6mW hours annually which is equal to about 6 SREC's (rate may vary) that your utility must buy from you. Value for these REC's when the program begins is usually around $400 per REC which is huge! This program is also legislated to be in progress for 10 years and even then it may be extended!



Net Metering in Illinois

Net metering is available for all home/business owners in Illinois. The reason for net metering being so important is that solar produces the most during the day when most people are out the house, this excess power is exported to the grid and the customer recieves retail value for that power in the for of a credit on your bill. If you go over your bill balance then that's money in your pocket.



Simplified Illinois Interconnection guidelines

Illinois has state interconnection guidelines so connecting to the grid and taking advantage of net metering isn't too difficult. Even if it were complicated your local solar pros know what to do and will sort it out for you.
