The use of **half-cut technology** helps minimize losses at connections and improves the module's performance under partial shading - which translates directly into more predictable energy production on roofs with chimneys, skylights, or in multi-row installations. Another key feature of this series is **the bifacial design**, which allows for more efficient use of light reflected from the ground - particularly in PV farms and on light-colored membrane roofs. Thanks to the **multi-busbar system** (10BB is used in this series), the module effectively collects current from the surface of the cells, supporting long-term reliability. This makes it a good choice for investors seeking a balance between cost and performance - in commercial, industrial, and utility applications, where **cost per square meter** and consistent parameter repeatability in larger deliveries are important. ## Notable figures - Efficiency of 20.5% is 0.8pp below the \*\*PERC 550-600W\*\* median (21.3%) - Power density of 212.8 W/m² matches the \*\*PERC 550-600W\*\* median - Temperature coefficient of -0.35%/°C matches the \*\*PERC 550-600W\*\* median - Weight of 32.0 kg is 1.2 kg above \*\*PERC 550-600W\*\* median (30.8 kg) - verify structural support - Ranked #11308 out of 14005 panels for efficiency in the database ## Questions ### How much power does a single Techwise Solar Sun-Pursuit TW-560HC panel generate? The Sun-Pursuit TW-560HC panel reaches a maximum power output of 560 Wp. This is a high value for its class, achieved by combining monocrystalline PERC cells in a half-cut layout with bifacial technology, which allows the module to generate additional energy from its rear side thanks to reflected light off the ground. ### How does half-cut technology in the TW-560HC differ from standard panels? In a half-cut layout, cells are cut in half, reducing current losses at connections and limiting the impact of partial shading on overall module performance. In practice, this means more stable energy output on roofs with chimneys, skylights, or multi-row installations where shadows only cover part of the surface. ### Does the bifacial design of the Sun-Pursuit panels actually increase energy yield? Yes, the bifacial TW-560HC modules capture light reflected from the ground surface, resulting in additional energy production compared to standard monofacial panels. The effect is strongest in ground-mounted solar farms and on light-colored membrane roofs with higher reflectivity. On dark sloped roofs the gain is smaller but still present. ### What warranty comes with the Techwise Solar TW-560HC panels? The Sun-Pursuit TW-560HC series comes with a 15-year product warranty and a 30-year linear power output warranty. This covers both material and workmanship defects in the module and guarantees a defined power performance level over the long-term operation of the installation. ### What kind of installations are the Sun-Pursuit TW-560HC panels best suited for? Thanks to their high 560 Wp output, bifacial construction, and 10BB multi-busbar layout, this series is primarily suited for commercial, industrial, and utility-scale installations where cost-per-square-meter efficiency and consistent parameters across large batch deliveries matter most. It offers a good balance between price and energy yield. ### What does the 10-busbar (10BB) layout offer in the TW-560HC panels? The 10BB multi-busbar layout increases the number of current-collecting paths across the cell surface, improving current collection efficiency and reducing the risk of microcracks affecting performance. In practice, this results in better long-term reliability and more stable operating parameters throughout the warranty period. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/tw-560hc-en-4f5422217f27.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +4.5 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +4.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +4.2 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +4.1 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +4.0 pp | | [Techwise Solar TW-530HT](https://comparepv.com/panel/techwise-solar-tw-530ht) | 530 W | -20 W, lighter, -5 yr warranty | | [Techwise Solar TW-535HT](https://comparepv.com/panel/techwise-solar-tw-535ht) | 535 W | -15 W, lighter, -5 yr warranty | | [Techwise Solar TW-560HC-540W](https://comparepv.com/panel/techwise-solar-tw-560hc-540w) | 540 W | -10 W, -0.4 pp | | [Techwise Solar TW-545HT](https://comparepv.com/panel/techwise-solar-tw-545ht) | 545 W | Lighter, +0.6 pp, -5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +100 W, cooler, +4.7 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +95 W, cooler, +4.5 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +90 W, cooler, +4.3 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +85 W, cooler, +4.1 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +80 W, cooler, +3.9 pp | --- Source: https://comparepv.com/panel/techwise-solar-tw-560hc-550w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
