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. Trust (data & verification). Owner-verification, completeness of contact info, and review-volume credibility.
- 2. Recommendation (rating). The Google star rating, Bayesian-shrunk toward the category mean so a few 5-star reviews can't dominate.
| Provider | Trust (data & verification) | Recommendation (rating) |
|---|---|---|
| Great Sky Solar | Strong | Strong |
| Koala Insulation of Nashville | Strong | Strong |
| Solar Service | Strong | Strong |
| SunMade Smart Roofing, Solar Fresno & Electric | Strong | Strong |
| MidKnight Solar | Strong | Strong |
| Solar-Verse | Strong | Strong |
| Solar RNR | Strong | Strong |
| Gold Path Solar | Strong | Strong |
How we chose these
We rank every active provider in every active solar business in the U.S. 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.

How to choose a solar pro
The ranking does the research; these five checks help you turn the shortlist into the right hire.
- 1
Start with the top of the ranking, not an ad
The providers ranked highest here 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
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
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
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
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 the U.S. for solar
12-month demand index (100 = annual average). Peaks in May, troughs in December. Book in the trough months to lock lower rates.
Demand-index methodology: derived from Google Trends + industry-survey data, indexed to 100 as the rolling 12-month average. Local market may vary 10-25%.
Pricing: what solar costs
Quick budget estimates by job type. Use these as a planning sanity-check, not as a firm quote.
| Job | Low | High |
|---|---|---|
| System install (per kW, gross) | $24,000 | $36,000 |
| Federal ITC offset (30%) | $-1,350 | $-900 |
| Battery storage (per 10 kWh) | $72,000 | $104,000 |
Estimates based on industry-average labor + materials, adjusted for local market. Get at least two written quotes from providers above before signing.
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
Finding a trustworthy solar pro is hard. Reviews are gamed, marketing claims are loud, and the gap between a great operator and a sketchy one isn't always obvious from a Google search. This page is meant to compress that research time.
We've cataloged every active solar provider in the U.S. (2,201 total across 38 states) and ranked them by a single composite ServiceAgent Score that blends data quality + verification (Trust Score) and rating + review volume (Recommendation Score, Bayesian-shrunk to prevent low-review providers from dominating).
Below: the nationwide top 25, a transparent methodology section, what each solar job usually costs in the U.S., and the red flags worth walking away from. For a tighter shortlist, drill into your state in the related pages section to see a state-specific ranking.
Frequently asked questions
8 common questions about hiring a solar pro in this area.
Who is the best solar company in the U.S.?
Based on our composite scoring of every active provider, Great Sky Solar in Lexington, MA ranks #1 (ServiceAgent Score 8.8/10). Note: "best in the U.S." is mostly a curiosity rank for solar - homeowners are far better served by the state-level or city-level ranking since most solar pros serve a single metro.
How much does solar service cost?
Nationally, 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?
The biggest 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 are usually the most expensive after the fact.
What should I look for when hiring a solar pro?
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, find someone who can.
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 end the conversation.
How does the ServiceAgent Score work?
It's a 0-10 composite of a Trust Score (40% - data quality + verification + review-volume credibility) and a Recommendation Score (60% - Google rating Bayesian-shrunk toward the category mean). Full formula on the methodology page.
Are these listings verified?
