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. ## Notable figures - Efficiency of 21.8% is 0.7pp below the \*\*TOPCon 450-500W\*\* median (22.5%) - 218.1 W/m² power density is 7.1 W/m² below \*\*TOPCon 450-500W\*\* median (225.2 W/m²) - requires larger installation area - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 450-500W\*\* panels - At 27.5 kg, this panel is 3.5 kg heavier than the \*\*TOPCon 450-500W\*\* median (24.0 kg) - more demanding for installation crews - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface ## Questions ### 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. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/tw-505ht-02-en-1a8a4a72fba8.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +3.2 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +3.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +2.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +2.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +2.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, lighter, +2.7 pp | | [Techwise Solar TW-490HT-02](https://comparepv.com/panel/techwise-solar-tw-490ht-02) | 490 W | +0.2 pp | | [Techwise Solar TW-495HT-02](https://comparepv.com/panel/techwise-solar-tw-495ht-02) | 495 W | +10 W, +0.5 pp | | [Techwise Solar TW-500HT-02](https://comparepv.com/panel/techwise-solar-tw-500ht-02) | 500 W | +15 W, +0.7 pp | | [Techwise Solar TW-505HT-02](https://comparepv.com/panel/techwise-solar-tw-505ht-02) | 505 W | +20 W, +0.9 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +75 W, cooler, +3.0 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +70 W, cooler, +2.8 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +65 W, lighter, +2.6 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +55 W, lighter, +2.6 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +55 W, lighter, +2.6 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +60 W, cooler, +2.5 pp | --- Source: https://comparepv.com/panel/techwise-solar-tw-485ht-02 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
