The Techwise Solar Sun-Pursuit Pro (TW-500HTS-06) series is designed to maximize energy production from the same roof or ground area - particularly in situations where every square meter counts and long-term stability is essential. The use of N-type TOPCon cells helps minimize losses typical of older technologies and maintain high efficiency over many years of operation. These are also bifacial modules, meaning they can generate additional power from reflected light - a significant advantage on bright roofs, ground-mounted structures, or in farm installations.

Another key feature is excellent performance in low-light conditions, which translates to better morning, evening, and cloudy-day performance in typical Polish weather. The series also has PID resistance, which reduces the risk of power drops in demanding installations and long strings. This makes it a good choice for investors who want to combine high power density with operational safety - from residential rooftops to commercial buildings and larger installations.

Common questions

6 answered
How do the N-type TOPCon cells in the Sun-Pursuit Pro series (TW-500HTS-06) differ from older PERC panels?
N-type TOPCon cells have lower recombination losses and reduced light-induced degradation compared to conventional PERC cells. In practice this means higher module efficiency, better high-temperature performance, and slower power decline over the years, resulting in higher energy yield over the system's lifetime.
Are the Techwise Solar Sun-Pursuit Pro TW-500HTS-06 panels bifacial?
No, the TW-500HTS-06 series is a monofacial module, even though it uses TOPCon cell technology, which in other variants is also offered as bifacial. It generates energy only from direct and diffuse light hitting the front side of the panel, so it does not add extra yield from albedo light reflected off the ground.
What warranty comes with the Sun-Pursuit Pro TW-500HTS-06 panels?
The manufacturer provides a 12-year product warranty covering material and workmanship defects, plus a 25-year power performance warranty. This means that after a quarter century of use, the panel should still deliver the manufacturer's guaranteed percentage of rated power output, which is standard for modern TOPCon-based modules.
Is the 500 Wp panel in the TW-500HTS-06 series suitable for a residential rooftop installation?
Yes, 500 Wp per module is currently one of the more popular ratings for residential PV systems, delivering high string power with fewer panels than older models. This shortens installation time and reduces the number of MC4 connectors or optimizers needed, lowering the overall system cost.
Does the Sun-Pursuit Pro TW-500HTS-06 perform well in low-light conditions and Polish climate?
Yes, TOPCon technology responds well to low irradiance, allowing the panel to more efficiently capture morning, evening, and overcast-day light, common in the Polish climate. This translates into higher real-world annual yield compared to older cell technologies under the same sunlight conditions.
What does PID resistance mean in Techwise Solar panels and why does it matter?
PID (Potential Induced Degradation) is power loss caused by voltage differences between cells and the frame or mounting structure, especially common in long strings and high system voltages. PID resistance in the TW-500HTS-06 series reduces the risk of such performance drops, which matters for larger commercial installations with long panel strings.
