How to choose a solar installer in Illinois

Check licensing & certification

Solar installs in Illinois involve electrical work, so the contractor (or their electrician) needs the proper state license. Favor companies with NABCEP-certified staff, the industry's recognized credential, and confirm they carry liability insurance and a workmanship warranty, not just the manufacturer's panel warranty.

Get three quotes and compare price per watt

Quotes vary widely. Compare the total cash price divided by system size (dollars per watt) rather than the monthly financed payment, which can hide markups. Make sure each quote lists the same panel and inverter brands, the production estimate, and exactly what's included.

Confirm permits, interconnection & net metering

A reputable installer pulls the building/electrical permits and files the utility interconnection paperwork for you. Ask how net metering works with your local Illinois utility: it determines how much credit you earn for excess power you send back to the grid, which drives your real savings.

What to know before hiring in Illinois

The largest utilities serving Illinois homes are Commonwealth Edison (2,922,223 residential customers, 15.2¢/kWh), Ameren Illinois (520,498 residential customers, 15.3¢/kWh) and MidAmerican Energy (73,564 residential customers, 10.0¢/kWh). Your utility sets the rate your solar production offsets, and it is also who an installer files interconnection or service paperwork with, so name it when you ask for quotes.

Check the license before you sign

Illinois licenses electrical contractors at the city or county level rather than statewide; the City of Chicago Department of Buildings, Trade Licensing is the starting point. Illinois has no statewide electrician license; Chicago licenses Supervising Electricians and Electrical Contractors, and other cities and counties run their own programs.

Frequently asked questions

Get at least three written quotes, confirm the company holds the licenses Illinois requires for electrical and solar work, check that they pull permits and handle the utility interconnection, and look for NABCEP-certified installers. Compare total price per watt, the equipment brands offered, and the workmanship warranty, not just the monthly payment.
