Why trust this list

When you need solar work done in Louisville, 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 Louisville, Kentucky (15 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 15), followed by what to look for, what each project usually costs in Louisville, 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.

How we chose these

We start from every active Google Business Profile in Louisville 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.

Local context

$Louisville sits in $Kentucky's broader solar services market, which our data suggests has 15 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 Louisville

  • 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

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 15 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 15 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 Louisville 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. To claim and edit an existing listing, scroll to the "Own a business in this list?" banner near the bottom of this page.
