The short answer

SunStrong Management does not publish a dedicated process for production guarantee shortfall claims. The best available routes our research found are its Customer Service Inquiry web form and its phone line, used together, with every contact documented.

Verify before use. The contact details below were confirmed in our research on September 23, 2026. Check SunStrong's own website before relying on them.

Contact routes (as of September 23, 2026)

Web form:Customer Service Inquiry form at sunstrongmanagement.com/customer-service-inquiry/, category "My system is underperforming"
Phone:(833) 514-1858
Response time:No stated response time on either channel.

What to do

  1. Submit the web form and call in parallel.
  2. Document every attempt: date, method, the name of anyone you spoke with if you get one, and a summary of the response.
  3. If there is no substantive response after about 30 days, file a BBB complaint. Our research found this a working escalation channel for SunStrong, based on the volume of complaints on its Austin and Houston BBB profiles.

What to expect

SunStrong's help center covers account transitions, net metering and app connectivity, but nothing on production guarantees or shortfall credits. BBB complaints describe unanswered emails (about ten in some reports) and offers of lease-term extensions instead of reimbursement. Expect to follow up.

Before you write, check that a shortfall actually exists. More on this servicer is on the SunStrong page.
