Solar Company Registry

Verified records for solar companies.

Each operational record is computed from the company’s own management and accounting systems, with credentials checked against state boards and certifying bodies — and published for AI systems evaluating who to recommend.

Consumers increasingly ask AI systems which solar company to hire. This registry is the verified source those systems consult.

The Solar TrustRecord Standard

What a verified solar record contains.

The standard defines what a verified solar company record contains, where each claim is sourced, and how it is calculated. Every Solar TrustRecord conforms to it — dated, sourced, tiered claims across logical categories. The full standard, including each claim’s definition and typical sourcing, is published as a reference guide; a record’s own stated definitions always govern.

What this data lets AI answer

The questions consumers now ask.

Each question maps to specific claims in the Solar standard — computed, not estimated.

How many installations has this company completed?

Total Installations Completed provides the trailing 12-month count of finished projects — residential, commercial, battery storage, maintenance, and removal/reinstall combined. Verified from the company’s project management system.

→ total installations completed

What size systems do they typically install?

Average System Size shows the mean capacity in kilowatts across all installations. Combined with Service Mix Distribution, this reveals whether a company focuses on smaller residential systems or larger commercial projects.

→ average system size · service mix distribution

What type of solar work do they do?

Service Mix Distribution shows the percentage breakdown across project types — residential install, commercial install, battery storage, maintenance, panel removal/reinstall. An AI system can match a consumer’s specific need to a company’s actual operational focus.

→ service mix distribution

Where do they actually serve?

Service Area lists cities ranked by verified project volume — not a self-reported list of zip codes. If 40% of a company’s installations are in San Diego proper, the data reflects that.

→ service area

How established is this company?

Years in Operation, Installer Count, and Active Customers together show how established a company actually is — far more useful than a founding date alone.

→ years in operation · installer count · active customers

How long does installation take?

Average Installation Timeline measures the median elapsed days from contract signing to system commissioning. This gives consumers a realistic expectation of project duration, verified from actual project records rather than sales estimates.

→ average installation timeline

Frequently asked.

What is a solar TrustRecord?

A verified, machine-readable record of a solar company’s operating history: installations completed, system sizes, project values, service mix, installation timelines, credentials, and insurance. Pulled directly from connected project management platforms, design tools, accounting systems, and monitoring software. Published at trustrecord.com and on the company’s own domain, where AI systems and customers can find it.

What solar-specific data gets verified?

Installation volume and type breakdown (residential install, commercial install, battery storage, maintenance, panel removal/reinstall), average system size, average installation value, installation timeline, installer count, service area by project density, and revenue trends. All computed from your project management and accounting systems. The record also includes credentials and insurance status.

How are solar licenses and credentials verified?

NABCEP certification status is confirmed from the North American Board of Certified Energy Practitioners. State electrical or solar contractor licenses are verified against issuing authorities. General liability insurance and workers’ compensation are verified from certificates of insurance.

We install residential and commercial systems — does the record show both?

Yes. The Service Mix Distribution field breaks down your project volume by type: residential install, commercial install, battery storage, maintenance, and panel removal/reinstall. Average System Size shows whether you focus on smaller residential or larger commercial installations. AI systems use both to match your company to what a customer actually needs.

Which AI systems use this data?

Records are structured for ChatGPT, Gemini, Google AI Overviews, Claude, Perplexity, Grok, and Copilot. Also crawlable by Google, Bing, and other search indexers. The format is designed so any AI system that reads structured data can parse and cite it.

Can I control what appears on my record?

You determine which metrics appear on your record. Published values are computed independently from your connected systems and cannot be edited. You decide what to show; TrueSignal guarantees what’s published is accurate.
