Additional information about technology

DAH Solar DHN-48Z20/DG(BW) panels use N-Type TOPCon cells, which ensure high efficiency, better operation at elevated temperatures and good performance in low light conditions.

No-Busbar technology shortens the current transmission path, reduces losses and improves conversion efficiency. The double glass structure increases the mechanical resistance of the modules and improves durability over a long period of use.

Bifacial modules can use light reflected from the ground, so they are particularly suitable for light roofs, ground structures and in installations where the back side of the panels has access to the reflected radiation.
