Suntis, a leading innovator in solar technology, has conducted a series of groundbreaking tests on two of its latest solar panel models: the TBC Dolphin series and the TOPCon Shark series. The tests, aimed at comparing the overall power output of both panels, reveal interesting results that could impact commercial and industrial solar installations.
The TBC Dolphin series, which utilizes TBC technology, delivers an impressive 650W of front power output on the mainstream 2382*1134mm 72-cell module. Meanwhile, the TOPCon Shark series, based on the advanced TOPCon technology, provides 620W of front power output under the same module size. However, the differences don’t stop at the front power rating—both panels feature bifacial technology, but with varying performance levels. The TBC Dolphin’s bifaciality rate is 75%, while the TOPCon Shark achieves a slightly higher rate of 80%. Both panels also exhibit a similar reflectance coefficient of 0.135, indicating their ability to harness reflected light.
In an experimental setting, Suntis researchers calculated the “total power” output of each module, taking into account the additional power generated by the rear side of the panels. Here’s how the numbers stacked up:
• TBC Dolphin Series: 650W (front) + 0.75 * 0.135 * 650W (bifacial power) = 715.81W (total power)
• TOPCon Shark Series: 620W (front) + 0.8 * 0.135 * 620W (bifacial power) = 686.96W (total power)
The TBC Dolphin panels outperformed the TOPCon Shark panels by a significant margin. In fact, the TBC module produced an additional 28.85W, resulting in a 4.2% power gain over the TOPCon panels.
Even in extreme conditions with a higher reflectance coefficient of 0.3, the TBC panels still came out on top, providing a 3.5% higher power output compared to the TOPCon modules.
The implications of these results are substantial for commercial and industrial solar installations. Whether in standard installation environments or under higher reflectance conditions, the TBC Dolphin series consistently delivers higher total power output than the TOPCon Shark series. Suntis’ findings may push the company to prioritize the TBC technology in large-scale solar projects, offering enhanced energy production and efficiency for their customers.
