What it does
This bill amends the Truth in Lending Act to require creditors offering solar financing to clearly disclose all dealer fees, third-party charges, and the true cost of credit to consumers. It closes a loophole where solar installers and lenders hide fees under a regulatory exemption, and bans forced arbitration in solar loan disputes, giving consumers the right to sue.
Why we flagged it
The bill's core mechanism is a disclosure mandate and arbitration ban designed to protect consumers from hidden fees in solar financing. It is a straightforward consumer-protection measure with no hidden riders or self-dealing provisions.
What the text implies
- The arbitration ban may increase litigation costs for solar lenders and installers, potentially raising financing costs for all consumers if passed through; however, this is a direct trade-off for legal remedy access.
- Creditors may respond by tightening underwriting or raising interest rates on solar loans to offset disclosure and litigation risk, potentially reducing access for marginal borrowers.
- The definition of 'solar financing transaction' is broad enough to capture EV charging stations and related infrastructure, extending protections beyond traditional rooftop solar.
