The use of **N-type cells in TOPCon technology** helps minimize degradation-related losses, ensuring the module maintains stable performance under real-world conditions. This solution is ideal for investors seeking to boost production without expanding the structure - especially in commercial and industrial projects. The key advantage of this series is the **bifacial design**, capable of utilizing reflected light from the back, increasing the yield where standard panels "see" only front illumination. Additionally, the **tempered glass with anti-reflective coating** improves performance under poor insolation and minimizes reflection losses. The IP68 connector box housing completes the package, crucial in installations exposed to moisture, dust, and varying weather conditions. The TS-BBT72 series stands out by combining high power density with practical durability, not just "paper" parameters. ## Notable figures - Efficiency of 22.3% matches the \*\*N-type 550-600W\*\* median - At 222.6 W/m² power density, roof space requirements are typical for \*\*N-type 550-600W\*\* panels - Temperature coefficient of -0.29%/°C matches the \*\*N-type 550-600W\*\* median - Weight of 27.2 kg (2.3 kg below \*\*N-type 550-600W\*\* median of 29.5 kg) allows easier transport and roof mounting - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### What is the maximum power output of the Sunova TS-BBT72 panel and what drives it? The top variants in the TS-BBT72 series reach up to 575 Wp. This high output comes from N-type TOPCon cells with low intrinsic losses combined with a half-cut cell layout that reduces resistive and thermal losses. Together with the bifacial dual-glass design, the module also captures rear-side reflected light, meaningfully boosting the total energy yield of the array. ### How does the bifacial TS-BBT72 panel differ from a standard monofacial panel? A monofacial panel only captures light hitting its front surface, while the TS-BBT72's bifacial design and transparent rear glass allow it to also collect light reflected off the roof, ground, or a bright surface beneath the array. In practice this means higher energy yield from the same footprint, especially in ground-mount systems installed over light-colored surfaces or gravel. ### What warranty applies to Sunova TS-BBT72 modules? The manufacturer provides a 15-year product warranty and a 30-year power performance warranty, with output guaranteed to remain at a high level throughout the module's service life. It is still worth confirming current service terms with the local distributor, since the manufacturer is based in China and is not a Tier 1 producer, which can affect the logistics of warranty claims. ### Is the TS-BBT72 suitable for large ground-mount and utility-scale installations? Yes, the TS-BBT72 series was designed for large rooftops and ground-mount solar farms, where maximizing power density per square meter matters most. Unit power up to 575 Wp reduces the number of modules needed, and the bifacial construction adds further energy gains in ground-mount systems, where reflected light plays a bigger role than on residential pitched roofs. ### Is the TS-BBT72 junction box resistant to moisture and harsh weather? Yes, the panel uses an IP68-rated junction box, the highest protection class commonly used in photovoltaics. This provides effective sealing against moisture, dust, and contaminants, which matters most in installations exposed to rain, fog, or dust, such as industrial rooftops and ground-mount projects. ### Does the tempered anti-reflective glass on the TS-BBT72 improve performance in low-light conditions? Yes, the front tempered glass with an anti-reflective coating reduces light reflection losses and helps the module make better use of diffuse radiation, for example on cloudy days or during early morning and evening hours. As a result, the panel maintains more stable energy production across variable sunlight conditions, not just under full direct sun. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ts-bbt72-570-590-271651b72715.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.5 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.3 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, lighter, +2.1 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | -35 W, lighter, +2.1 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | -35 W, lighter, +2.1 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | -30 W, cooler, +2.0 pp | | [AIKO AIKO-A625-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a625-mah72dw) | 625 W | +50 W, heavier, +1.9 pp | | [Sunova RS535~555S8-144GA (535W)](https://comparepv.com/panel/thornova-rs535-555s8-144ga-535w) | 535 W | Hotter, heavier, -1.6 pp | | [Sunova TS-BG72(540)](https://comparepv.com/panel/sunova-ts-bg72-540) | 540 W | Hotter, heavier, -1.4 pp | | [Sunova TS-BW72(545)](https://comparepv.com/panel/sunova-ts-bw72-545) | 545 W | Hotter, -1.2 pp, -5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +75 W, cooler, +2.9 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +70 W, cooler, +2.7 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +65 W, cooler, +2.5 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +60 W, cooler, +2.3 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +55 W, heavier, +2.1 pp | --- Source: https://comparepv.com/panel/sunova-ts-bbt72-575 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.
