The Sunova TS-BG54 X Series (400-415 W) consists of compact modules with a 108-cell array, designed to easily fit into typical roof slopes and maximize the available surface area. The bifacial design helps to recover additional energy from the rear side as well - a real advantage in situations where light reflection is important (e.g., a light-colored roof, gravel, or membrane). The modules are manufactured using monocrystalline PERC technology, which ensures stable performance under a wide range of conditions and good energy production in the Polish climate. The series also features long warranties and positive power tolerance, making it easy to design installations without the risk of "underperforming" parameters. It is an ideal choice for residential and small commercial installations, especially when you want to increase energy production without increasing the roof size and opt for a competitive solution compared to standard monofacial modules.

Common questions

6 answered
Are Sunova TS-BG54 X Version panels bifacial, and is it worth it?
Yes, the TS-BG54 X Version series uses a bifacial design, allowing the module to generate additional energy from light reflected onto its rear side. This is a real benefit on light-colored roofing, gravel, or roofing membranes with higher reflectivity. In typical residential conditions, the rear-side gain usually adds a few percent to annual energy yield without increasing the installation footprint.
What warranty comes with Sunova TS-BG54 X Version modules?
The manufacturer provides a 25-year product warranty and a 30-year power output warranty. This means the module is covered against material and manufacturing defects for a quarter century, while a guaranteed energy production level is warranted over 30 years according to the manufacturer's power degradation curve. This is among the longer warranty terms currently available on the PV module market.
What is the maximum power output of the TS-BG54 X Version series?
The series is offered in a power range of 400 to 415 Wp, with the top variant reaching 415 Wp. The modules use monocrystalline PERC cell technology with a 108-cell layout, delivering good efficiency per unit area in a compact format that makes efficient use of available roof space.
Are Sunova TS-BG54 X Version panels suitable for a typical pitched residential roof?
Yes, the compact 108-cell format was designed to fit well onto standard pitched roof surfaces found on residential homes. This makes it easier to lay out modules with minimal wasted space, while the bifacial design further increases energy yield from the same installation, which is especially useful when roof area is limited.
What does positive power tolerance mean for Sunova TS-BG54 X Version panels, and why does it matter?
Positive power tolerance means the module's actual output will not fall below its rated nameplate power, and may even slightly exceed it. For installers and investors, this ensures the designed system reaches its intended total capacity, removing the risk of underestimated energy production during component sizing and customer performance calculations.
How do bifacial monocrystalline PERC modules differ from standard monofacial panels?
Monofacial modules capture energy only from their front surface, while bifacial PERC modules like the TS-BG54 X Version series also harvest light reflected onto the rear side from the surrounding surface. This results in higher annual energy production from the same roof area, while the monocrystalline PERC cells maintain stable performance across varying weather conditions, including Poland's climate.
