The application of **bifacial PERC technology** enables better utilization of reflected light, helping to increase yield compared to conventional single-sided panels. The modules are based on **monocrystalline half-cut cells**, which better withstand partial shading and minimize losses from operation at higher temperatures - essential for rooftops on warehouse halls and commercial buildings. Another highlight of this series is the **full All Black aesthetics** - the black frame and seamless front simplify the design of installations on properties where the investor demands a discreet appearance. Additionally, the **high waterproofing class of the junction box** enhances safety when operating in more challenging environmental conditions. This is an excellent choice for installers and investors implementing farms and C&I systems, who want to combine modern design with reliable performance and longevity for years to come. ## Notable figures - Efficiency of 21.3% matches the \*\*PERC 550-600W\*\* median - Power density of 212.9 W/m² matches the \*\*PERC 550-600W\*\* median - At -0.33%/°C, hot weather performance is typical for \*\*PERC 550-600W\*\* panels - Weight of 27.6 kg (3.2 kg below \*\*PERC 550-600W\*\* median of 30.8 kg) allows easier transport and roof mounting - Bifacial design (70% factor) captures reflected light - adds 4-10% yield on ground-mount or white roof ## Questions ### What is the maximum power output of Sunova TS-BB72 (All Black) panels? The Sunova TS-BB72 (All Black) series reaches a maximum power output of up to 560 Wp. This high per-unit power reduces the number of modules needed to reach a target system size, which is especially valuable for large solar farms and C&I installations where efficient use of available roof or ground area matters. ### What is bifacial technology in the Sunova TS-BB72 panels and is it worth choosing? Bifacial technology means the panel generates power from both sides, capturing light reflected off the ground, roof, or surrounding light-colored surfaces on its rear side. In the TS-BB72 series, this delivers a measurable energy yield boost compared to standard monofacial panels, particularly on light-colored commercial roofs or ground-mounted sites with favorable albedo. It's worth choosing for large installations, where even a few extra percentage points of yield meaningfully improve project economics. ### What warranty comes with Sunova TS-BB72 (All Black) panels? The manufacturer provides a 15-year product warranty along with a 25-year power performance warranty. This means the module is expected to maintain its guaranteed output level for a quarter century, while the manufacturer covers material and workmanship defects for the first 15 years - a standard warranty structure for modern monocrystalline panels in this class. ### Are Sunova TS-BB72 panels suitable for commercial rooftop installations? Yes, the TS-BB72 (All Black) series was designed primarily for large-scale C&I and solar farm installations. Monocrystalline half-cut cells reduce power losses from partial shading, for example caused by rooftop ventilation units or adjacent equipment, while PERC cell technology maintains stable energy production even at the higher operating temperatures common on large commercial roof surfaces. ### What does All Black mean for Sunova TS-BB72 panels, and does it affect efficiency? All Black refers to a uniformly black frame and a consistent black front surface with no contrasting visible components. This is primarily an aesthetic feature, valued in projects where the visual appearance of the installation matters to the investor or surroundings. The black finish itself does not reduce energy performance - that is determined by the PERC half-cut cells and bifacial technology used in the module. ### Is the junction box on Sunova TS-BB72 panels resistant to harsh weather conditions? Yes, TS-BB72 series modules feature a junction box with an elevated ingress protection rating, improving the safety and durability of electrical connections under moisture, dust, and significant temperature fluctuations. This is particularly important for industrial rooftop and solar farm installations, where panels are exposed to demanding environmental conditions over many years of operation. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/thornova-ts-bb72-540-560-all-black-2815ecae70f9.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, +3.7 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, +3.5 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, +3.4 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, +3.3 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | -50 W, cooler, +3.2 pp | | [Sunova RS535~555S8-144GA (535W)](https://comparepv.com/panel/thornova-rs535-555s8-144ga-535w) | 535 W | Heavier, -0.6 pp, +5 yr warranty | | [Sunova TS-BG72(540)](https://comparepv.com/panel/sunova-ts-bg72-540) | 540 W | Heavier, -0.4 pp, +5 yr warranty | | [Sunova TS-BW72(545)](https://comparepv.com/panel/sunova-ts-bw72-545) | 545 W | Very close match | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +100 W, cooler, +3.9 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +90 W, cooler, +3.5 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +85 W, cooler, +3.3 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +80 W, cooler, +3.1 pp | --- Source: https://comparepv.com/panel/sunova-ts-bb72-550 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.
