Product Q&A

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

We provide flash test reports, series numbers, power rates, voltage, and current for each individual panel. We also offer flash test photos and EL photos for every panel to ensure they are new and defect-free.

Q:Why should I choose your company over competitors offering lower prices?

Cheaper panels often use low-efficiency cells without Flash and EL testing, leading to hidden cracks and fire risks. GAMKO performs 3 EL tests and 2 Flash tests during production to ensure high quality and safety.

Q:How to ask for support if product failure in warranty?

Email us with the PI number, serial number, product S/N, PCB board number, and a detailed description of the failure with pictures or video. We will submit your case to the after-sales department and provide solutions within 24 hours.
