Sun-Pursuit Plus Series photovoltaic panels based on 132 cells are a breakthrough solution utilizing advanced TOPCon technology, which redefines efficiency standards in modern solar energy. Thanks to the use of n-type wafers, these modules offer significantly better resistance to light-induced degradation, which directly translates into a longer service life while maintaining high initial efficiency. The design consisting of 132 cells allows for precise voltage and current management, effectively reducing resistive losses and improving system operation in partial shading conditions. This series stands out from the competition with an excellent temperature coefficient, which ensures that the installation maintains high productivity even on the hottest days of the year. It is a solution dedicated to demanding commercial projects and large PV farms, where maximizing yields from limited mounting space is of key importance. Using Sun-Pursuit Plus eliminates the risk of premature power decline, offering investors exceptional energy stability and a much faster return on costs. Thanks to their unique cell structure, these modules show great sensitivity to diffuse radiation, which guarantees continuity of energy production even under cloudy skies, placing them at the forefront of the most cost-effective technologies available on the market today. This is a product that combines innovation with reliability in extreme weather conditions.

Common questions

6 answered
How does TOPCon technology in Sun-Pursuit Plus panels differ from standard PERC cells?
TOPCon (Tunnel Oxide Passivated Contact) technology uses n-type wafers with an additional passivation layer that reduces carrier recombination and boosts efficiency compared to conventional p-type PERC cells. As a result, Sun-Pursuit Plus modules degrade more slowly over time and show better resistance to light-induced degradation (LID), delivering higher energy yield across the module's lifetime.
What warranty comes with the Sun-Pursuit Plus Series 132-cell panels?
Techwise Solar backs the Sun-Pursuit Plus series with a 12-year product warranty and a 25-year linear power output warranty. Material and manufacturing defects are covered for the first 12 years, while the guaranteed power output percentage is maintained on a linear degradation curve throughout the full 25-year term.
Are Sun-Pursuit Plus panels bifacial?
No, the Sun-Pursuit Plus Series TOPCon 132-cell module is a mono-facial panel, optimized for standard rooftop or ground-mount installations that don't rely on reflected light from the rear side. If you need extra energy yield from albedo light, Techwise Solar also offers a bifacial version built on the same TOPCon platform.
How do Sun-Pursuit Plus panels perform in high summer temperatures?
Thanks to TOPCon technology and n-type wafers, these modules have a favorable temperature coefficient of power, which limits output loss as panel temperature rises. In practice, this means smaller energy losses during hot summer days compared to older PERC-based technologies, which matters especially for roof installations with limited airflow underneath the panels.
What installations is the Sun-Pursuit Plus series with up to 625 Wp best suited for?
With up to 625 Wp per module and a 132-cell design, this series is built primarily for large commercial installations and utility-scale PV farms where maximizing yield per unit of mounting area is critical. The high per-module power output reduces the total panel count needed, cutting down on racking and cabling costs in large-scale projects.
Do Sun-Pursuit Plus panels perform well under cloudy skies or partial shading?
Yes, the TOPCon cell structure gives these modules good sensitivity to diffuse irradiance, helping maintain energy production even on overcast days. The 132-cell layout also improves voltage management under partial shading, limiting the impact of individual shaded cells on the overall output of the module string.
