How the top solar pros compare

The same ServiceAgent Score components that drive the ranking, scored side by side — so you can see at a glance where each provider is strongest.

The criteria we scored against

  1. 1. Trust (data & verification). Owner-verification, completeness of contact info, and review-volume credibility.
  2. 2. Recommendation (rating). The Google star rating, Bayesian-shrunk toward the category mean so a few 5-star reviews can't dominate.
  3. 3. Review depth. How many public reviews back the rating — more reviews, more reliable the signal.
  4. 4. Score confidence. How much data stands behind the composite score for this provider.

How we chose these

We rank every active provider in every active solar business in Illinois by a composite ServiceAgent Score (0-10) made up of two components:

Trust Score (40%) - rewards owner-verified status, completeness of contact info, presence of hours/coordinates/photos, and review-volume credibility.

Recommendation Score (60%) - Google rating Bayesian-shrunk toward the category mean using a 25-review prior so high-volume providers can't be dethroned by 5-star outliers.

Composite ServiceAgent Score = 0.6 × Recommendation + 0.4 × Trust. We re-compute as new reviews land and as providers claim their listings. The "Last updated" date at the top of this page reflects the most recent data refresh.

What we deliberately don't do: pay-to-rank, sponsored slots that masquerade as editorial picks, or hide our formula. Sponsored slots (if/when introduced) will be clearly labeled and won't affect editorial ranking.

The approach

Sunrise Solar Solutions is a smaller or newer entrant in St. Charles with 16 public reviews so far. The smaller sample makes the 4.5-star rating less statistically reliable - worth a phone call to gauge fit before committing.

  • Maintains an active website with service detail.
  • Direct phone published - no lead form gatekeeping.
  • Active on Google with up-to-date contact info.

✓ Strong review signal

4.5-star average across 16 reviews puts them in the upper tier for solar providers in St. Charles.

⚠ Watch out for

Low review volume makes the rating statistically noisy. Get references from 2-3 recent jobs before signing.

Our take

Ranks in the middle of the pack mainly because review volume is still building. The rating itself is strong; treat them as a "worth a quote" rather than a default pick.

Low review volume makes the rating statistically noisy. Get references from 2-3 recent jobs before signing.

Our take

Ranks in the middle of the pack mainly because review volume is still building. The rating itself is strong; treat them as a "worth a quote" rather than a default pick.

The approach

Nautilus Solar Energy, LLC operates in Chicago with 194 Google reviews at 3.2 stars - a steady mid-tier signal in our composite scoring.

  • Maintains an active website with service detail.
  • Direct phone published - no lead form gatekeeping.
  • Active on Google with up-to-date contact info.

✓ Strong review signal

Public review history is limited so far - the headline rating is 3.2 from 194 reviews. Treat the score as provisional.

⚠ Watch out for

After-hours and emergency response isn't signaled on the public profile - confirm availability directly if your job is time-sensitive.

Our take

Mid-tier ranking in this market. Quality looks reasonable but isn't a standout vs. the top 3 - use them if you can't get a quote from a higher-ranked provider in time.

How to choose a solar pro

The ranking does the research; these five checks help you turn the shortlist into the right hire.

  1. 1

    Start with the top of the ranking, not an ad

    The providers ranked highest in Illinois earned it on review depth, rating, and data completeness — not on ad spend. Shortlist two or three from the top before you start calling.

  2. 2

    Get two or three quotes in writing

    Pricing for solar work varies by scope and local market. Written quotes from a few shortlisted pros let you compare apples to apples and spot an outlier before you commit.

  3. 3

    Read the most recent reviews, not just the average

    A strong average can hide a recent slide in quality. Sort reviews by newest and look for how the business handles problems — a thoughtful reply to a bad review often tells you more than the star count.

  4. 4

    Confirm licensing, insurance, and scope before work starts

    Ask for the license number and proof of insurance, and get the full scope of work plus any parts/labor warranty in writing before any solar job begins. Verify the license on your state board if the work is significant.

  5. 5

    Match the provider to your actual job

    A high-volume operator is great for a routine job; a smaller specialist may be a better fit for an unusual one. Use the scorecard above to pick for your situation, not just the overall rank.

When demand peaks in Illinois for solar

12-month demand index (100 = annual average). Peaks in May, troughs in December. Book in the trough months to lock lower rates.

Pricing: what solar costs

Federal ITC offset (30%)$-1,350$-900

What to know about hiring Solar

A few things are worth knowing before you hire, whatever the specific job.

What drives the price

Scope of work, materials, access, and whether it's a routine job or an emergency with after-hours rates.

What to check

Current license and insurance for the trade, a written quote and scope, and any workmanship warranty.

When to call

Get two or three quotes for planned work; for anything that's a safety or water-damage risk, sooner is cheaper.

Why trust this list

Frequently asked questions

8 common questions about hiring a solar pro in this area.

Who is the best solar business in Illinois?

Based on composite ServiceAgent Score across every active provider in Illinois, SLR Solar Panel Installer in Skokie ranks #1 (8.2/10). WindSoleil in Chicago (8.2/10) ranks #2 and Priority Solar Installation in Chicago (8.2/10) ranks #3.

How much does solar service cost in Illinois?

Across Illinois, solar jobs span $10,000 - $45,000 depending on scope. $22,500 median for a 6 kW residential install before the 30% federal tax credit. Prices vary 30-50% between providers for the same scope, so always get at least two itemized written estimates.

What drives the price difference between solar providers in Illinois?

Several factors:

• System size in kW (the biggest driver) • Roof type + pitch (tile + steep adds labor) • Local utility interconnection fees • Whether you finance vs. pay cash (dealer fees on loans average 18-25%)

Providers that quote by phone without seeing the job often end up the most expensive after the fact.

What should I look for when hiring solar in Illinois?

Use this checklist:

• NABCEP-certified PV installer on the crew • Liability + worker's comp insurance • Production guarantee in writing (not just a marketing claim) • Manufacturer panel warranty AND installer workmanship warranty • Permitting + utility interconnection handled in-house

If the provider can't or won't meet these basics, there's no shortage of pros in Illinois - move to the next one on the list.

What are the biggest red flags?

The patterns we see most often in disputes:

• ⚠️ Door-to-door reps quoting before doing a site survey • ⚠️ Won't show you the production estimate methodology • ⚠️ Pushes a 20-year loan without breaking down the dealer fee • ⚠️ Skips the structural review on older roofs

Any one of these is reason enough to politely walk.
