Does my guarantee survive the bankruptcy?
Production guarantee obligations under Sunnova, SunPower, and PosiGen leases/PPAs were transferred to the current servicing entity through the bankruptcy sale process, not discharged by it. That applies to the majority of outstanding leases and PPAs in the field.
Is this a collections service?
GuaranteeCheck never contacts your servicer, never claims to act on your behalf, and is never a party to your claim. The letter it drafts is written in your own voice, for you to review, sign, and send yourself. That's a deliberate design choice, not a limitation. It sidesteps any question of third-party standing to claim on your behalf.
What if I don't have SolarEdge admin access?
SolarEdge monitoring requires admin rights on your account, and orphaned-system owners often don't have them. The original installer usually held the admin account, and installer bankruptcy means it typically can't transfer normally. GuaranteeCheck supports a CSV export from your own SolarEdge login where you do have access, and a manual numeric-entry fallback where you don't, so this doesn't block you from running the diagnostic.
What does GuaranteeCheck Plus include?
$3.99/month or $29.99/year gets you unlimited diagnostic re-checks, an automatic re-run near your true-up date, and claim-letter generation included with no separate $99 completion fee. Worth it if your lease has a recurring true-up period (most do, every 24 months) rather than a one-time check.
Is my data safe?
Your lease terms (guaranteed production, true-up rate/interval) and your production data (from Enphase or SolarEdge) are used only to run your diagnostic and, if you request one, draft your claim letter. See the Security and Privacy pages for the full breakdown, including the current state of payment processing.
Getting started
Yes. The diagnostic engine, true-up calculation, and claim-letter generator are live and ready to run against your own numbers. There's no self-serve signup yet, so you start by emailing us your servicer and lease details and we run the check with you.
