FAQ

What international certifications does the 620W XHE-66G-DEGH have?

It is fully certified to IEC 61215, IEC 61730, CE,etc. These certifications ensure compliance with global safety, performance and environmental requirements.

Does this panel have anti-PID (Potential Induced Degradation) protection?

Yes. It is designed with advanced anti-PID technology, ensuring minimal power loss even under high humidity and high temperature conditions throughout its 30-year service life.

What cell technology does the 620W XHE-72N-DEGH use?

It adopts 210R N-type TOPCon half-cut cells with 132-cell design. This advanced cell technology delivers higher efficiency, better low-light performance and lower internal resistance than traditional cell designs.

What are the dimensions and weight of the XHE-66G-DEGH 630W solar panel?

The XHE-66G-DEGH 630W panel measures 2384×1134×30mm and weighs approximately 33.9kg.

With this double-sided photovoltaic panel, how much additional energy can I expect to generate on the back side?

Under normal installation conditions, you can expect to gain 10% to 25% additional energy from the back side. In the best conditions (such as white gravel or snow-covered ground, and with an appropriate installation height), the gain can reach up to 30%.
