Solar Installer Record Maps
Solar installer license explorer colored by license and activity fields
Explorer colors follow the selected license or activity field; gray marks unavailable data.

Independent, source-linked public records

Put license, recent activity, and cost context next to the solar bid.

Compare explicit California, Connecticut, Florida, and Oregon solar or renewable-energy contractor classes plus the Colorado and Minnesota electrical-contractor licenses used where no solar-specific class exists, with California-only interconnection activity and cost-per-watt evidence.

What the data adds

Research the record before the sales conversation.

01

Find the complete field

Search the public roster instead of a paid subset, then filter on facts that affect fit.

02

Keep dimensions separate

Licensing, activity, inspections, services, and outcomes stay distinct rather than becoming an opaque score.

03

Verify at the source

Each record retains provenance so time-sensitive claims can be checked before a decision.

Current release

Built from named public sources

This release combines explicit California, Connecticut, Florida, and Oregon solar or renewable-energy contractor classes with the Colorado and Minnesota electrical-contractor classes those states use in place of a solar-specific license. Privacy-preserving CPUC residential photovoltaic aggregates match California licenses only; license, activity, and cost remain separate dimensions.

Common questions

What this record can and cannot tell you

Does more application activity mean a better installer?

No. It only indicates matched source-reported activity.

Is median cost per watt a bid estimate?

No. It is historical context, not a quote.

Does a clear license guarantee workmanship?

No. It confirms a source-reported license status, not project quality.
