SunStrong production guarantee, checked against your real numbers.
If your system was originally installed under Sunnova or SunPower and is now serviced by SunStrong Management, your lease's production guarantee generally survived that bankruptcy. SunStrong just isn't volunteering to pay shortfalls it finds. Public complaint records show a pattern of requests being refused or going unanswered even when homeowners ask directly.
No dedicated claims process, and a documented pattern of non-response.
How to actually reach SunStrong about this
Submit your claim letter and evidence packet through SunStrong's Customer Service Inquiry form, selecting the “My system is underperforming” category, then follow up by phone to confirm it was received.
Run the check, get a letter that names this pattern.
GuaranteeCheck's SunStrong claim letter is written to account for exactly this. It includes the submission and escalation guidance above directly in the letter, so you know what to do if the first attempt goes unanswered, without guessing.
