The use of bifacial solutions allows for better utilization of light reflected from the ground, which translates to increased production in areas where every square meter of roof space counts. The full black aesthetic makes installation on residential buildings and premium properties easier, without compromising performance. A key feature is **the bifacial design**, and in some models, **double glazing (dual glass)**, which improves resistance to harsh working environments and promotes stable performance over time. The series is designed for rooftop applications, from single-family homes to **commercial and industrial (C&I) installations**, where long-term reliability and predictable performance are crucial. The TS-BBT54 stands out from the competition due to its **high-efficiency N-type**, sensible module design, and focus on durability, especially in projects where operating conditions can be demanding. ## Notable figures - Efficiency of 22.5% is 0.6pp above the \*\*N-type 400-450W\*\* median (21.9%) - At 225.3 W/m² power density, this panel generates 7.0 W/m² more per unit area than \*\*N-type 400-450W\*\* median (218.3 W/m²) - At -0.29%/°C, hot weather performance is typical for \*\*N-type 400-450W\*\* panels - At 20.5 kg, this panel is 1.5 kg lighter than \*\*N-type 400-450W\*\* median (22.0 kg) - easier handling during installation - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface ## Questions ### What is the N-type cell technology used in Sunova TS-BBT54 panels, and how does it differ from standard P-type? N-type cells use phosphorus-doped silicon instead of boron, making them less prone to light-induced degradation (LID) and delivering higher conversion efficiency, especially at high temperatures. In practice this means higher annual energy yield and a slower power decline over time compared to older P-type technologies such as PERC. ### What does bifacial design mean for the TS-BBT54 modules, and how much extra energy can it generate? TS-BBT54 panels are bifacial, generating power from both the front and rear side by capturing light reflected off the mounting surface. Depending on the albedo of the surface (light gravel, snow, white roofing membrane) and mounting height, the additional energy gain can range from a few percent to over ten percent annually compared to monofacial panels. ### What warranty comes with Sunova TS-BBT54 panels? The manufacturer offers a 15-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. This means the module should maintain a guaranteed percentage of its initial power output over three decades, a standard comparable to leading N-type panel manufacturers on the market. ### Is Sunova a Tier 1 manufacturer, and does that matter when choosing panels? Sunova is not currently listed as a Tier 1 manufacturer under the Bloomberg NEF classification, indicating less track record with large-scale bank project financing than market leaders. This does not directly affect the technical quality of the module, but for large commercial projects it's worth verifying financing terms and warranty service availability through the local distributor. ### Are the full black Sunova TS-BBT54 panels suitable for a single-family home roof? Yes, the full black version was designed for residential aesthetics - the black frame and black backsheet conceal the busbar grid, giving the array a uniform, discreet look on the roof. Bifacial technology works particularly well when mounted on light-colored roofing or elevated, ventilated racking systems. ### Are TS-BBT54 panels with up to 440 Wp power output better suited for residential or commercial installations? With power output up to 440 Wp combined with bifacial design and, in select variants, dual glass construction, the TS-BBT54 series suits both residential rooftop installations and commercial and industrial (C&I) projects, where long-term reliability and predictable energy yield across large roof or ground-mounted areas are key. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ts-bbt54-425-440-all-black-22ca6cb60ffe.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +50 W, cooler, +2.0 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +50 W, cooler, +2.0 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +45 W, cooler, +1.8 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +45 W, cooler, +1.8 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +45 W, cooler, +1.8 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +45 W, cooler, +1.8 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +45 W, heavier, +1.8 pp | | [Sunova TS-BW54(400)](https://comparepv.com/panel/sunova-ts-bw54-400) | 400 W | Hotter, -2.0 pp, -5 yr warranty | | [Sunova TS-BG54(405)-X](https://comparepv.com/panel/sunova-ts-bg54-405-x) | 405 W | Hotter, heavier, -1.8 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +70 W, cooler, +2.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +55 W, cooler, +2.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +65 W, cooler, +2.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +60 W, cooler, +2.0 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +60 W, cooler, +2.0 pp | --- Source: https://comparepv.com/panel/sunova-ts-bbt54-440 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.
