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.

Common questions

6 answered
What is the warranty on the S-Energy SL65-72BDJ Bifacial Half-Cut series?
S-Energy provides a 12-year product warranty covering materials and workmanship, along with a 30-year linear power warranty. After 30 years of operation the module is guaranteed to retain at least 84.95% of its rated peak power. We recommend confirming warranty service terms with your local authorized distributor, as after-sales support conditions may vary by region.
How much more energy does the bifacial SL65-72BDJ produce compared to a standard single-sided panel?
The bifacial double glass design of the SL65-72BDJ series allows rear-side energy capture that can add 10 to 30% to overall energy yield compared to a conventional monofacial module. The actual bifacial gain depends heavily on ground albedo: installations over light-colored gravel, white roofing membranes, or snow deliver the highest rear-side irradiance. Dark asphalt or grass will produce a lower bifacial boost.
Are the SL65-72BDJ modules compatible with single-axis trackers?
Yes, the SL65-72BDJ series is purpose-built for large commercial and utility-scale PV plants where single-axis trackers are the norm. The double glass construction provides the structural rigidity and long-term mechanical reliability required for continuous dynamic rotation. At 2278 by 1134 mm and approximately 31.5 kg per module, the form factor aligns with standard utility-scale tracker specifications.
What is the practical benefit of half-cut cells in the SL65-72BDJ, especially under partial shading?
Half-cut cell technology splits each PERC cell into two halves, halving the operating current per string and cutting resistive losses accordingly. The 144-cell layout also means the module is split into two electrically independent halves, so partial shading from a chimney, antenna, or adjacent row affects only a portion of the module output rather than the entire string. The result is a more stable daily production profile in real-world conditions.
How do the SL65-72BDJ modules perform in cold temperatures and overcast conditions?
With a temperature coefficient of Pmax at -0.35% per degree Celsius, the SL65-72BDJ can exceed its rated 550 Wp on cold, sunny winter days. The PERC cell architecture also improves sensitivity to diffuse irradiance, delivering better output under overcast skies than older standard-efficiency modules. The double glass frame withstands snow loads up to 5,400 Pa, making it well-suited for Central and Northern European climates.
Can the SL65-72BDJ be installed on a flat commercial rooftop, or is it strictly a ground-mount solution?
The SL65-72BDJ is suitable for flat commercial rooftops, but its large footprint of 2278 by 1134 mm and weight of roughly 31.5 kg per module require a robust ballasted racking system or direct roof-deck fastening. The double glass structure is rated for snow loads up to 5,400 Pa and wind loads up to 2,400 Pa, making it mechanically safe in demanding climates. A light-colored TPO or PVC membrane beneath the array can also enhance rear-side bifacial gain significantly.
