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 start from every active Google Business Profile in Chicago tagged solar, then score each business on two dimensions:

Trust Score (40% of the composite, 0-10) rewards owner-verified status (claimed listings get a 3-point bump), completeness of contact information (phone, website, address, hours, coordinates, photos, service categories), and review-volume credibility - a provider with 200+ reviews is treated as more trustworthy than a provider with the same star rating but only 5 reviews.

Recommendation Score (60% of the composite, 0-10) is the Google star rating shrunk toward the category mean using a Bayesian prior. Without this step, "5.0 from 2 reviews" would outrank "4.7 from 240 reviews" - which is exactly backwards. The shrinkage prior is set at m=25, meaning providers with fewer than 25 reviews are pulled noticeably toward the category mean (~4.6).

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 feeding this ranking.

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.

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 Chicago 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.

Local context

$Chicago sits in $Illinois's broader solar services market, which our data suggests has 17 actively-operating providers within the city limits and surrounding metro. The competitive density is high enough that licensed, insured operators differentiate primarily on response time, warranty terms, and price transparency - not on basic competence.

Pricing drivers in Chicago

  • 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%)

What to verify before signing

  • 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

Red flags to walk away from

  • ⚠️ 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

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

When you need solar work done in Chicago, the first hour of research is usually the most expensive part - reading reviews, decoding marketing claims, and trying to figure out who's actually a licensed pro vs. someone with a truck and a Google listing. This page is meant to compress that hour into about five minutes.

We've cataloged every active solar business in Chicago, Illinois (17 total) and ranked them by a single composite ServiceAgent Score - a weighted blend of *trust signals* (data quality, verification status, review-volume credibility) and *quality signals* (rating, review count, response time). The result is a list where high-volume, well-reviewed, complete-data providers float to the top, and where a "5-star from 3 reviews" outfit doesn't get to outrank a 4.7★ provider with 240 reviews.

Below: the ranked list (top 17), followed by what to look for, what each project usually costs in Chicago, the red flags that should make you walk, and a methodology section that shows our exact formula. If you run one of these businesses, the Claim your listing banner near the bottom takes you through a 2-minute verification flow to get a green badge, edit your description, and bump your placement.

Frequently asked questions

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

Who is the best solar provider in Chicago, Illinois?

Based on our composite scoring, WindSoleil ranks #1 with a ServiceAgent Score of 8.2/10 (72 reviews, 4.9★). Priority Solar Installation ranks #2 (8.2/10) and FreeWorld Electric & Solar ranks #3 (8.2/10). These rankings refresh as new reviews come in.

How much does solar service cost in Chicago?

Costs in Chicago for solar work span $10,000 - $45,000 depending on scope. $22,500 median for a 6 kW residential install before the 30% federal tax credit. Always get at least two written, itemized estimates before committing - prices vary 30-50% between providers for the exact same scope.

What drives the price difference between solar providers?

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 without seeing the job are often the most expensive in the end - the "estimate" turns into a much higher final bill after they arrive.

What should I look for when hiring a solar pro in Chicago?

Use this checklist before signing anything:

• 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, walk. There's no shortage of pros in Chicago - we've cataloged 17 of them on this page alone.

What are red flags to avoid when hiring solar in Chicago?

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 grounds to politely end the conversation and move to the next provider on this list.

Are these solar listings verified?

All 17 listings are pulled from active Google Business Profile data, which means each business has confirmed its location, name, and contact details with Google. Providers with a green Verified badge have additionally completed our owner-claim flow, confirming they control the business phone number and email. As of the latest refresh, 0 of these 17 listings are ServiceAgent-verified.

How does the ServiceAgent Score work?

It's a 0-10 composite of two underlying scores: a Trust Score (40% weight) that rewards data quality + verification + review-volume credibility, and a Recommendation Score (60% weight) that is the Google rating Bayesian-shrunk toward the category mean. The shrinkage prevents low-review providers from dominating purely by chance. Full formula on the methodology page.

Can I get free quotes from multiple solar providers at once?

Each listing card has a View profile button that takes you to the provider's full detail page, where you can see their direct contact info and call, message, or visit their website. ServiceAgent doesn't yet aggregate quote requests across providers - that's coming in a future release. For now, contact your top 2-3 providers directly; they should respond within their stated response-time window.

Why does the ranking change between visits?

Two reasons. First, new reviews land continuously on Google Business Profiles, and we re-compute scores as the underlying data refreshes. Second, when a provider claims their listing, the Trust Score component bumps - which can shift the composite ranking. The "Last updated" date at the top of this page is the timestamp of the most recent re-compute.

I'm a business owner - how do I get my listing on this page?

If your business has an active Google Business Profile in Chicago tagged solar, it should already be here. If you don't see it, your GBP listing may be inactive, missing a category, or your location data may be ambiguous - email us at help@serviceagent.ai and we'll investigate.
