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. ## Notable figures - Module efficiency of 21.9% is 0.6pp below average for \*\*TOPCon 550-600W\*\* panels (median: 22.4%) - At 218.7 W/m², this panel generates 5.7 W/m² less per unit area than \*\*TOPCon 550-600W\*\* median (224.4 W/m²) - Temperature coefficient of -0.34%/°C is 0.05pp worse than \*\*TOPCon 550-600W\*\* median (-0.29%/°C) - higher losses in summer heat - #6962 for efficiency, #8778 for temperature performance out of 14005 panels ## Questions ### 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. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/TW-580TSD-EN-ed2f3af8e2e6.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.9 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.7 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, 16 kg lighter, +2.5 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Cooler, lighter, +2.5 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | Cooler, lighter, +2.5 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | Cooler, lighter, +2.4 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | Cooler, lighter, +2.3 pp | | [Techwise Solar TW-530HT](https://comparepv.com/panel/techwise-solar-tw-530ht) | 530 W | Lighter, -1.3 pp, -5 yr warranty | | [Techwise Solar TW-535HT](https://comparepv.com/panel/techwise-solar-tw-535ht) | 535 W | Lighter, -1.2 pp, -5 yr warranty | | [Techwise Solar TW-560HC-540W](https://comparepv.com/panel/techwise-solar-tw-560hc-540w) | 540 W | -25 W, -1.8 pp | | [Techwise Solar TW-545HT](https://comparepv.com/panel/techwise-solar-tw-545ht) | 545 W | Lighter, -0.8 pp, -5 yr warranty | | [Techwise Solar TW-550HT](https://comparepv.com/panel/techwise-solar-tw-550ht) | 550 W | Lighter, -0.6 pp, -5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +85 W, cooler, +3.3 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +80 W, cooler, +3.1 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +75 W, cooler, +2.9 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +70 W, cooler, +2.7 pp | --- Source: https://comparepv.com/panel/techwise-solar-tw-565tsd-1 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.
