How We Score Installers
Every installer listed on EnergyRanked receives an objective quality score based on publicly available data. We do not accept payment for higher scores. Our methodology uses five weighted categories to produce a single 0–100 rating that helps homeowners compare contractors at a glance.
1. Licensing & Certifications (25%)
We verify each company’s state contractor license, NABCEP certifications, manufacturer authorizations (such as Tesla Powerwall Certified or Enphase Platinum), and other industry credentials. Companies with current, verifiable credentials score higher.
2. Customer Reviews (25%)
We aggregate review data from Google Business Profile, the Better Business Bureau, and other public sources. The score accounts for average star rating, total review volume, recency of reviews, and the ratio of positive to negative feedback.
3. Experience & Track Record (20%)
Longer-operating companies with a proven installation history earn more points. We look at years in business, estimated number of completed installations, and whether the company has maintained consistent operations without major disruptions.
4. Service Coverage & Responsiveness (15%)
This category evaluates how well a company serves its listed areas. Factors include the number of service areas, response time to inquiries (where data is available), and whether the company offers free consultations or site assessments.
5. Warranty & Financing Options (15%)
We review the workmanship warranty length, whether the company offers financing or helps customers navigate incentive programs, and the clarity of their pricing and contract terms as reported by customers.
Data Sources
Our data comes from public records, state licensing databases, Google Business Profiles, BBB filings, and manufacturer partner directories. We refresh scores regularly and welcome corrections from installers and homeowners.
Limitations
No scoring system is perfect. Our ratings reflect publicly available information and may not capture every aspect of a company’s service quality. We encourage homeowners to get multiple quotes, verify licenses independently, and read recent reviews before making a decision.
If you believe a score is inaccurate, please contact us with details and we will investigate promptly.
