PV Modules: Bifacial technology
go PV
Current status
Module variations: frameless glass-glass vs framed glass-backsheet
.
Frameless glass-glass:
•
Better backside performance as there are no frame that may shadow cells near the edges
.
Better mechanical performance
•
•
•
Glass-glass configuration causer lower degradation rates and module guarantee can be extended
Framed glass-backsheet:
.
Lower weight
Less breakages during transportation and installation
•
Installation can be made with traditional clips. Can save labor cost.
There is not a clear winner. Some manufacturers offer both options.
Nevertheless some manufacturers recommend glass-glass only for high mechanical loads
and/or high humidity applications.
•
Glass-glass + frame also possible.
•
Glass-Transparent backsheet without frame not possible due to mechanical requirements.

Bifacial with
dual glass
1. Most on-ground PV
station;
2. High labor cost area,
like EU, Japan,
Australia (can effective
receive labor cost);
3. Commercial roof-top
1. Most on-ground PV
station;
2. In floating projects as
well as super high wind
speed area, bifacial with
dual glass is a better
choice
