Middle of its segment, needs the roof space
S-Energy SL65-72BDJ BIFACIAL HALF-CUT Series are advanced bifacial modules that maximize energy yield by effectively utilizing light reflected from the ground. The applied bifacial double glass technology ensures the panels generate additional power from the rear side of the cells, which is particularly beneficial on surfaces with high albedo, such as light gravel or white roof membranes. The use of half-cut cells significantly reduces resistive losses and improves the module's resistance to the negative effects of partial shading, resulting in more stable power production throughout the day. This series effectively addresses the problem of performance degradation over time, offering exceptional resistance to mechanical loads and corrosive factors thanks to the use of double glass instead of a traditional backsheet. It is a solution designed primarily for large commercial investments and solar farms, where the key goal is to optimize the LCOE. What distinguishes these modules from the competition is their increased durability in extreme weather conditions and precise compatibility with tracking systems. Thanks to the unique design, investors receive a tool that guarantees maximum energy yields while maintaining the highest standards of fire and mechanical safety over many years of operation.

- At 20.5% efficiency, this panel is on par with typical PERC 500-550W modules
- Power density of 205.2 W/m² is 3.8 W/m² below PERC 500-550W median (209.0 W/m²) - needs more roof space
- At -0.35%/°C, hot weather performance is typical for PERC 500-550W panels
- At 31.5 kg (3.1 kg above PERC 500-550W median of 28.4 kg), requires checking roof load capacity
- 70% bifaciality enables rear-side power generation, boosting yield by 4-10% on reflective surfaces
