Indian module manufacturer Saatvik has developed bifacial PV modules with 21.12% efficiency and 545 W of peak power output. The multi-busbar modules feature half-cut passivated emitter rear contact (PERC) cells based on M10-sized monocrystalline wafers.
The backside of the bifacial module provides up to 25% additional power gain. The bifacial gain is significant on grassland, dry sand, and especially in snowfields. The modules come with a linear warranty of up to 30 years.
Recently, Saatvik raised its production output to 1 GW through the addition of a 500 MW mono PERC panel factory in Haryana. The new production base is equipped to make mono PERC, half-cut, multi-busbar technology to produce high-efficiency solar modules with a power output of 530 Wp to 610 Wp. It is coming up with an additional 1.2 GW capacity in Gandhidham, Gujarat.

Using bi-facial modules we can build a D-shaped structure 30 ft and above diametric distance placed East-West on farmlands, in-between 2-village houses or as arches. This will facilitate use of space/land/waterways/canals etc,. It could be erected over Wind-Mills.
