Product Q&A

Q:How can I trust the quality of your solar panels?

We provide new panels with individual flash test reports, serial numbers, and EL photos. Unlike stock panels, ours have a database to ensure no defects or broken cells.

Q:Why choose your company over cheaper alternatives?

Cheaper panels often use low-efficiency cells without Flash/EL testing, leading to hot spots and fire risks. We perform 3 EL and 2 Flash tests to ensure quality and safety.

Q:How to request support if a product fails during warranty?

Email us with the PI number, serial number, and detailed photos/videos of the failure. We will submit your case to our after-sales department and provide solutions within 24 hours.

Q:What is the warranty period for these solar panels?

We offer a 10-year product warranty and up to a 30-year service warranty for our solar panels.

Q:What certifications do your solar panels have?

Our solar panels are certified with CE, FC, and RoHS standards.
