The Sunova TS-BG54 series is designed for installations where stable energy production is crucial, even under less-than-ideal sunlight conditions and at higher temperatures. The modules utilize a bifacial design, enabling them to generate additional energy from the rear side as well - a significant advantage on bright roofs, membranes, and ground-mounted structures with appropriate ground cover. The use of half-cut cells improves performance under partial shading and reduces losses during daily operation, which will be appreciated by homeowners and small businesses.

Compared to many panels in this class, the TS-BG54 stands out with its double-glass design, which increases resistance to weather conditions and micro-cracks, as well as supports the long-term stability of performance parameters. The black-aesthetic versions are an added advantage for projects where appearance is important - without compromising functionality. This is a good choice for those seeking higher yields and predictable performance from their installations over many years.

Common questions

6 answered
Are Sunova TS-BG54 panels still available for purchase?
The Sunova TS-BG54 series has been discontinued and replaced by newer models from the manufacturer. Panels may still be available from distributors as remaining stock, so it's worth checking current inventory beforehand and confirming that the manufacturer's warranty still applies despite the series being discontinued.
What are the practical benefits of the bifacial design in TS-BG54 panels?
Thanks to the bifacial construction, the module captures additional energy reflected from the ground surface onto the rear side of the cells. The biggest gain, up to a few percent above standard output, is achieved on light-colored roofs, EPDM membranes, and ground-mounted systems with high-albedo surfaces such as light gravel or grass.
What warranty comes with Sunova TS-BG54 panels?
The manufacturer provides a 15-year product warranty and a 30-year linear power output warranty. Although the TS-BG54 series has been discontinued, warranty terms remain valid for panels already purchased and installed, so it's important to keep the invoice and product datasheet.
How does the PERC technology in TS-BG54 differ from newer TOPCon cells?
PERC cells used in the TS-BG54 have slightly lower efficiency and a less favorable temperature coefficient than newer TOPCon or HJT cells, but they are a proven, mature technology with stable long-term performance. The panel still reaches up to 415 Wp of maximum power, a solid result for residential and small commercial installations.
Do TS-BG54 panels perform well under partial shading, such as from a chimney?
Yes, the half-cut cell layout limits output loss when part of the module is shaded. By splitting the panel into smaller segments, current generated by the unshaded portion is used more efficiently, reducing losses compared to standard full-size cell panels.
Is Sunova a tier 1 manufacturer and where is it based?
Sunova is not listed as a tier 1 manufacturer under the Bloomberg NEF classification, although it is an established Chinese manufacturer with a solid position in the renewable energy market. This is worth considering when arranging financing or insurance, as some banks and insurers prefer tier 1 brands only.
