The Sunova TS-BW54 (X Version) series are modules designed to maximize energy production from the same roof area - thanks to its bifacial design, it also effectively utilizes light reflected from the ground. This solution is particularly effective on bright roofs, roofs with membranes, and surfaces with high albedo, where the gain from the rear side is most noticeable.

The X version has been designed for stable operation in demanding conditions - the module features dual-glass, which better protects against moisture and accelerated material degradation than typical constructions with film. The use of PERC technology and half-cut cells reduces losses and improves the performance of the panels in partial shade, which is often crucial on roofs with dormers, chimneys, or antennas.

It is a good choice for home and commercial installations, where predictability of yields and longer warranty protection are important, without paying extra for "paper" parameters.

Common questions

6 answered
Is the Sunova TS-BW54 (X Version) still available for purchase?
The TS-BW54 (X Version) series has been discontinued and is no longer part of Sunova's current production lineup. Availability is now limited to remaining distributor stock. Anyone planning to expand an existing installation with this model should check stock levels quickly, since sourcing an identical matching panel later may not be possible.
How does the bifacial design of the TS-BW54 differ from a standard monofacial panel?
The bifacial TS-BW54 has active cells on both sides of the module, capturing not only direct sunlight but also light reflected off the ground surface. The actual energy gain depends on the albedo of the surface beneath the array - it performs best over light-colored roofs, PVC membranes, or light gravel. On a typical dark pitched roof, the bifacial gain is much smaller than on a flat roof.
What is the maximum power output and warranty of the Sunova TS-BW54 X Version?
The module reaches a maximum output of 415 Wp. The manufacturer offers a 25-year product warranty and a 25-year power performance warranty, exceeding the typical market standard of 10-12 years for product coverage. Buyers should still confirm with the seller whether warranty terms remain valid now that the series has been discontinued.
Does the dual glass construction in the TS-BW54 require different mounting than a standard backsheet panel?
The dual glass design is heavier than a typical panel with a rear polymer backsheet, so roof load capacity and mounting clamps compatible with the glass thickness should be checked before installation. The electrical installation process itself is no different from standard panels - dual glass simply offers better moisture protection and slower laminate aging over time.
Do the PERC half-cut cells in the TS-BW54 handle partial shading well?
Yes, splitting cells into half-cut segments limits the power drop of the entire panel when only part of it is shaded, for example by a chimney or antenna. PERC technology further boosts conversion efficiency through a rear light-reflecting layer. Together, these features make the panel perform more consistently on irregularly shaped roofs than older full-cell modules.
Is Sunova, as a tier 2 manufacturer, a worse choice than tier 1 brands?
Tier classification mainly reflects production scale and bank financing history, not directly panel quality. Sunova is headquartered in China and is not listed as tier 1, yet the TS-BW54 X Version series offers specs comparable to tier 1 brands, including a 25-year warranty. Buyers should focus on local warranty service availability, especially since this model has already been discontinued.
