Independent & transparent
The Honesty Index is built from public regulatory records. Companies cannot pay to improve their grade — methodology and source data are published in full at /methodology.
Updated quarterly
Each quarter we re-run the index against the latest enforcement filings, court dockets, and complaint databases. Grade changes are timestamped and historical grade trajectories are preserved on each company profile.
Used by industry
The Honesty Index API is licensed by solar lenders, insurance carriers, PACE administrators, and consumer-protection agencies. See /api for institutional access.
Don't let the cheapest quote turn into the most expensive mistake.
Every Insolar quote now displays the Honesty Grade of each recommended installer and financing partner. Same panels, same pricing — better information. Going solar should be simple, and trustworthy.
