The use of **monocrystalline cells in half-cut technology** improves performance under partial shading and reduces losses, which stabilizes energy output in typical rooftop conditions. This is a good choice if you want to maximize every square meter without adding more panels. The TS-BW72 also features **a bifacial design**, which allows it to "collect" additional light reflected from the ground. This is particularly effective on bright roofs, membranes, and ground-mounted installations. The panel has a **rigid, mechanically robust construction**, making it easier to maintain reliable performance in challenging wind and snow conditions. An additional advantage is **predictable performance over time** due to its stable degradation characteristics. This series is recommended for businesses, farms, and commercial projects where energy yield, durability, and investment cost are the primary considerations. ## Notable figures - Efficiency of 21.1% matches the \*\*PERC 500-550W\*\* median - Power density of 211.0 W/m² matches the \*\*PERC 500-550W\*\* median - Temperature coefficient of -0.33%/°C matches the \*\*PERC 500-550W\*\* median - 70% bifaciality enables rear-side power generation, boosting yield by 4-10% on reflective surfaces - In the top 66% for efficiency among all PERC panels ## Questions ### What is the maximum power output of the Sunova TS-BW72 panel? Modules from the TS-BW72 series reach a maximum power of up to 560 Wp. This is a strong result for this module class, achieved through monocrystalline PERC cells using half-cut technology. This allows for higher energy production from the same roof area compared to older, conventional panels. ### What does it mean that the Sunova TS-BW72 panel is bifacial? Bifacial technology means the panel generates electricity from both its front and rear sides, capturing light reflected off the ground surface. In the TS-BW72, this translates into additional energy yield, especially on light-colored roofs, roofing membranes, and ground-mounted installations where light reflection is greater. ### What warranty comes with Sunova TS-BW72 panels? The manufacturer provides a 15-year product warranty and a 25-year power performance warranty. This means the panel is expected to maintain its declared energy output for a quarter of a century, and the stable degradation curve further increases the predictability of the investment over time. ### Are Sunova TS-BW72 panels suitable for sloped roofs and ground-mount installations? Yes, the panel's rigid and mechanically resistant construction performs well on sloped roofs as well as ground-mount installations and roofing membranes. It's worth noting that fully leveraging the bifacial function requires an appropriate mounting angle and clearance beneath the panel to allow light reflection from the ground. ### How does half-cut cell technology in the Sunova TS-BW72 differ from standard cells? Half-cut cells are cut in half, reducing current losses and internal resistance in the module. In practice, the panel performs better under partial shading, such as from a chimney or antenna, and delivers more stable energy production compared to traditional full-size cells. ### Is it worth choosing Sunova TS-BW72 even though the manufacturer isn't Tier 1? Sunova is not listed as a Tier 1 manufacturer, but the TS-BW72 series offers solid technical specifications: up to 560 Wp of power, PERC half-cut technology, and bifacial construction, with standard 15/25-year warranty terms. For commercial and agricultural projects where price-to-yield ratio matters most, this can be a good choice, though it's worth comparing service availability against Tier 1 manufacturer offerings. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/thornova-ts-bw72-540-560-transparent-white-mesh-backsheet-8a9b36f1bcbb.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, +3.9 pp, +5 yr warranty | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +3.7 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, +3.7 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, +3.6 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, +3.5 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, +3.4 pp, +5 yr warranty | | [Sunova RS535~555S8-144GA (535W)](https://comparepv.com/panel/thornova-rs535-555s8-144ga-535w) | 535 W | Heavier, -0.4 pp, +5 yr warranty | | [Sunova TS-BG72(540)](https://comparepv.com/panel/sunova-ts-bg72-540) | 540 W | Heavier, -0.2 pp, +5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +105 W, cooler, +4.1 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +100 W, cooler, +3.9 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +90 W, cooler, +3.5 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +85 W, cooler, +3.3 pp | --- Source: https://comparepv.com/panel/sunova-ts-bw72-545 Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
