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 almost certainly 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.

What we know about SunStrong

No dedicated claims process, and a documented pattern of non-response.

The pattern: Multiple BBB complaints against SunStrong Management describe production-guarantee reimbursement requests being refused or simply ignored, even when a homeowner contacts them directly. SunStrong does not publish a dedicated claims process or a stated response time for these requests.

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.

Web form:sunstrongmanagement.com/customer-service-inquiry/
Phone:(833) 514-1858
If no response:File a BBB complaint (Austin or Houston profile) after about 30 days — other SunStrong customers have used this route to get a response.
