The Techwise Solar Sun-Pursuit Pro Series is designed for installations where high energy yield is crucial, even under challenging operating conditions. These modules utilize the TOPCon technology, available in both standard and bifacial versions. This allows them to better utilize reflected light from the ground, resulting in real benefits for solar farms, carports, and large industrial rooftops. The use of a half-cut design helps minimize losses and improves the module's performance under partial shading. Additionally, the denser multi-busbar (16BB) connection system ensures stable operation and resistance to micro-cracks during operation. In practice, this series solves a common problem for projects with limited space - it allows for maximizing energy production from the same area. For investors focused on aesthetics, FULL BLACK versions are also available, particularly desirable for residential and premium rooftop installations.

Common questions

6 answered
Are Techwise Solar Sun-Pursuit Pro Series panels suitable for a pitched roof?
Yes, the Sun-Pursuit Pro Series works well on pitched roofs, especially in the FULL BLACK variant, which is a popular aesthetic choice for residential and premium installations. The half-cut cell design reduces energy losses under partial shading, such as from chimneys or dormers, a common challenge in single-family homes.
What is the maximum power output of a Sun-Pursuit Pro Series module?
Sun-Pursuit Pro Series modules reach up to 620 Wp of maximum power. Thanks to TOPCon cell technology and a dense multi-busbar (16BB) grid, these panels deliver high energy yield from a limited roof or land area, which matters for projects with space constraints.
What warranty comes with Techwise Solar Sun-Pursuit Pro Series panels?
The manufacturer provides a 15-year product warranty and a 30-year power output warranty. This gives long-term protection for the investment, covering both build quality and guaranteed energy performance of the module throughout its service life.
What is TOPCon technology and is it worth choosing panels built with it?
TOPCon (Tunnel Oxide Passivated Contact) is a modern cell technology that delivers higher efficiency and better performance compared to older solutions like PERC. In the Sun-Pursuit Pro Series, this translates into higher energy yield, especially under challenging conditions such as elevated temperatures or lower irradiance, making it a solid choice for installations focused on maximizing production.
Is a bifacial version of the Sun-Pursuit Pro Series available?
Yes, the series is offered in both a standard and a bifacial variant, which additionally captures light reflected from the ground surface. The bifacial version is particularly effective in PV farms, carports, and large industrial rooftops, where installation conditions allow the rear side of the module to contribute to output.
How do the half-cut and multi-busbar design in the Sun-Pursuit Pro Series differ from standard panels?
The half-cut design splits cells in half, reducing current losses and improving module behavior under partial shading. The denser multi-busbar (16BB) grid increases the number of current-carrying pathways, improving operational stability and resistance to microcracks over years of use, which supports longer system lifespan.
