How much do solar installers make in Illinois in 2026?

The median solar installer in Illinois earns $59,630 a year — that works out to about $28.67 an hour based on a standard 2,080-hour year. That number sits in the middle of a fairly wide range. Workers at the 25th percentile bring in $47,890 ($23.02/hr), and those at the 75th percentile clear $70,800 ($34.04/hr). The $22,910 spread between the bottom and top quartiles tells you that experience, employer, and location move the needle significantly in this trade.

Entry-level installers in Illinois typically land somewhere around or below the 25th percentile. At $47,890 a year, that's a livable starting point, but it reflects the reality that new hires spend their first year learning roof work, panel layout, mounting systems, conduit runs, and the basics of DC wiring — all under direct supervision. Productivity is lower, and wages reflect it. Most workers cross the median within three to five years of consistent field experience, assuming they stay active on residential and commercial crews and pick up additional skills like battery storage, inverter troubleshooting, and system commissioning.

The 75th percentile at $70,800 ($34.04/hr) tends to go to lead installers and crew leads who manage job sites, handle the more complex commercial or industrial projects, and may carry additional credentials. Electrician licensing matters here — in Illinois, solar installers who pull permits or perform electrical work beyond low-voltage DC connections often need to work under or alongside a licensed electrician, and some pursue their own electrical license over time. That crossover into licensed electrical work is one of the clearest paths to pushing past the median.

Geography within Illinois shapes pay more than many workers expect. The Chicago metro — including Cook, DuPage, Lake, and Will counties — supports a larger volume of commercial and industrial solar projects, which tend to pay more than straight residential installs. Downstate markets are less active, which can mean less consistent work hours in a given year even if the hourly rate isn't dramatically different. Year-round work hours matter as much as the wage rate when you're calculating annual take-home.

Seasonality is a real factor in this trade in Illinois. Installations slow down during hard winter months — frozen rooftops, permit backlogs, and reduced daylight hours all cut into available work. Some employers keep crews busy with ground-mount projects, battery retrofits, or pre-construction electrical work to bridge the winter gap, but not all. Workers who want to stay closer to full-year hours often diversify by picking up electrical or HVAC crossover work in slower months.

Overtime exists in solar, particularly in spring and summer when project pipelines are deepest and crews are trying to hit installation quotas before fall. Some employers pay straight time-and-a-half for hours over 40 per week; others run flat hourly rates on salaried installs. If overtime potential matters to you, clarify how a prospective employer handles it before you accept an offer.

Some solar installers in Illinois work under collective bargaining agreements. If you're in a union shop, your wage will be set by your local's current agreement, not the BLS figures above. The BLS numbers reflect a blend of union and non-union workers across the state. If you're covered by a collective bargaining agreement, contact your local directly to get the current wage scale for your classification.

The data here comes from the BLS Occupational Employment and Wage Statistics (OEWS) survey, May 2025. The OEWS captures base wages paid by employers — it does not include overtime premiums, per diem, employer-paid benefits, or incentive pay. Your total compensation package may be higher than the figures above once those items are factored in.

To move up the pay scale in this trade in Illinois, the most direct levers are: accumulating years of field experience on varied project types, pursuing electrical licensing or at minimum a journeyman-level understanding of low-voltage and line-side DC/AC systems, getting certified on battery storage platforms (which are in growing demand), and targeting employers who work commercial and industrial accounts rather than pure residential volume shops. Each of those steps has historically corresponded with pay closer to the 75th percentile or above.
