Solar Cancellation HQ is not a law firm and does not provide legal advice. This page is general information, and reading it or submitting a form does not create an attorney-client relationship. Not every contract qualifies, and no outcome is guaranteed. We never advise anyone to stop making payments on a solar loan, lease or PPA. Laws and utility rules change, so verify before acting.
