The Sunova TS-BW54 series consists of 54-cell modules designed for installations where maximizing power output per square meter of roof is crucial. The use of bifacial technology allows for energy balance even when sunlight reflects off a bright surface, rather than just directly onto the front panel. In practice, this means better utilization of diffuse light and increased resilience to production drops in challenging conditions.

The half-cut design minimizes internal losses and improves performance under partial shading - important for roofs with chimneys, skylights, or air conditioning systems. The panel also features anti-reflective glass, which facilitates light collection at low angles, typical in winter.

The TS-BW54 is a good choice for single-family homes and small commercial buildings, especially if you want to combine stable performance in warm weather with an aesthetically pleasing installation and predictable energy yields over the years.

Common questions

6 answered
Is the Sunova TS-BW54 series still available for purchase?
The TS-BW54 series has been discontinued by the manufacturer. Panels may still be available from distributors as final warehouse stock, but once that inventory is depleted, it will no longer be possible to purchase an identical model for system expansion. It's worth buying extra panels upfront if you plan to expand your installation later.
How does the bifacial technology in the TS-BW54 differ from a standard monofacial panel?
The bifacial TS-BW54 panel generates power from both its front and rear sides, capturing light reflected off the roof or ground surface. This typically results in extra energy yield, especially when installed above a light-colored roof or on ground-mounted racking with airflow beneath the panel. A standard monofacial panel only produces energy from the front and misses out on this additional gain.
What warranty comes with the Sunova TS-BW54 panels?
The manufacturer provides a 15-year product warranty covering material and workmanship defects, along with a 25-year linear power warranty guaranteeing a specified performance level over time. This is a standard warranty length for panels in this class, though some tier 1 manufacturers offer longer terms.
Are TS-BW54 panels suitable for roofs with partial shading, such as near chimneys?
Yes, the half-cut cell design used in the TS-BW54 splits cells in half, reducing power loss under partial shading from chimneys, dormers, or AC units. Shading on one section of the panel doesn't shut down the entire module, which is a meaningful advantage over older designs without this split.
What is the maximum power output of the TS-BW54 series, and how many panels are needed for a typical installation?
The maximum power rating for the TS-BW54 module is 415 Wp. For a typical residential system of 6-8 kWp, you'd need roughly 15-19 panels, depending on available roof space and orientation relative to the sun.
Do Sunova TS-BW54 panels perform well in high summer temperatures?
The PERC cells used in the TS-BW54 offer solid thermal stability compared to older cell technologies, though they're not as heat-resistant as newer TOPCon or HJT designs. The panel will perform adequately in summer heat, but expect a slightly larger efficiency drop during peak temperatures compared to the latest cell generations.
