3. FAQ

Is GlobalSunHub an installer or equipment seller?

No. GlobalSunHub is an informational platform. We help you compare equipment and plan system options, but we do not sell hardware or perform installations.

Are the specs always 100% accurate?

We do our best, but manufacturers can change specs and datasheets. If you spot a mismatch, please report it—this helps everyone.

Do you provide engineering or financial advice?

No. Outputs from calculators are estimates for educational purposes. Always validate final system design with qualified professionals and local regulations.

Can I request a new brand / model to be added?

Yes—email us with the brand/model name and, ideally, a datasheet link.

4. Report a Data Issue

If a spec is wrong (e.g., power, efficiency, dimensions, MPPT range, warranty), please send:

  • Product link on GlobalSunHub
  • Which field is incorrect
  • Correct value (if known)

Tip: The fastest way is to email support with subject: Data Issue – [Brand] [Model]
