Technical FAQs 3

What is a Longi 620w bifacial double glass solar panel?

Loading... The Longi 620W Bifacial Double Glass Solar Panel is a high-performance photovoltaic module designed for utility-scale, commercial, and industrial solar installations.

What is a 120 half cell bifacial double glass solar panel?

This 120 half cell HJT bifacial double glass solar panel provides a powerful combination of increased PV module efficiency, energy savings and durable long-term performance. Featuring a 22.4% module efficiency and 615-635 watts per panel, it delivers an advanced renewable energy source with zero emissions.

Which bifacial double glass module produces more energy?

The bifacial double glass module produces more energy. Our N-type models have superior bifaciality. This means that the rear side of the module can produce up to 85% of the energy generated by the front side. Thus, the panel generates more energy overall. Lower degradation means a higher return on investment.
