The Techwise Solar Sun-Pursuit Plus series is designed to maximize energy yield in situations where every square meter and stable performance in variable conditions matter. Its foundation is TOPCon technology, which helps maintain high module efficiency in daily operation, even under lower sunlight conditions. Bifacial variants also allow for further utilization of reflected light from the ground, which realistically increases energy production on flat roofs and in ground-mounted installations with sufficient surface area beneath the module.

Using half-cut cells minimizes losses and improves panel performance under partial shading, and the multi-busbar (16BB) design supports better current transport within the cell. For investors who prioritize aesthetics, Full Black versions are available - particularly desirable on modern residential and commercial roofs.

Sun-Pursuit Plus is a good choice for prosumers, companies, and PV farms that expect high-end technology and predictable yields without compromising.

Common questions

6 answered
How many Techwise Solar Sun-Pursuit Plus panels are needed for a 10 kWp system?
With a module power of 625 Wp, only 16 panels are required to reach a 10 kWp system (16 x 625 Wp = 10,000 Wp). This is significantly fewer modules than with older 350-400 Wp panels, resulting in fewer mounting points, faster installation, and better use of limited roof or ground space.
How does TOPCon technology in the Sun-Pursuit Plus differ from classic PERC panels?
TOPCon (Tunnel Oxide Passivated Contact) uses an additional passivation layer that reduces electron recombination on the rear side of the cell. As a result, Sun-Pursuit Plus modules achieve higher efficiency and a smaller power drop at rising temperatures compared to older PERC panels. In practice, this means higher yields, especially in summer and under partial sunlight conditions.
What is the warranty on Sun-Pursuit Plus panels and what does it cover?
Techwise Solar provides a 15-year product warranty covering material and workmanship defects, along with a 30-year power warranty guaranteeing a minimum energy output level throughout the module's service life. This is in line with current market standards for premium TOPCon panels, giving investors greater confidence in long-term return on investment.
Do Sun-Pursuit Plus Full Black panels lose performance compared to the standard version?
The Full Black version uses the same TOPCon technology and identical half-cut cell design, so the difference in efficiency is minimal to none - the black frame and backsheet do not significantly affect energy production. Choosing this version is mainly a matter of aesthetics, valued for installations on modern residential and commercial building roofs where visual appearance matters.
Do Sun-Pursuit Plus panels handle partial shading better than standard modules?
Yes, thanks to half-cut cell technology, the panel is divided into independent electrical sections, so shading part of the module - for example from a chimney or branch - doesn't shut down the entire panel, only reduces output in the affected section. The 16BB multi-busbar layout further improves current flow and reduces resistive losses under non-uniform lighting conditions.
Is the Sun-Pursuit Plus series better suited for residential or commercial installations?
The series is designed for both prosumers and businesses or utility-scale PV farms. The high per-module power output (625 Wp) works well for large ground-mounted and industrial installations where scale matters, while the availability of a Full Black version makes it equally attractive for residential installations focused on roof aesthetics.
