These are fully black (All Black) modules, creating a cohesive and elegant surface - particularly desirable for modern homes and buildings with high aesthetic requirements. The use of **monocrystalline** and **bifacial** modules allows for better utilization of reflected light from the ground, which can be a significant advantage on bright roofs, terraces, and ground-mounted structures. In practice, this series helps to minimize losses under variable sunlight conditions, increase daily energy yield, and improve cost-effectiveness in situations where the mounting surface is limited. Compared to many competing panels, it stands out due to its refined appearance, **a design focused on long-term durability**, and parameters optimized for predictable operation in typical Polish climate conditions. This makes it a good choice for prosumers, companies, and installers looking for premium modules for pitched and flat roofs. ## Notable figures - At 21.0% efficiency, this panel is on par with typical \*\*PERC 400-450W\*\* modules - At 210.0 W/m² power density, this panel generates 3.8 W/m² more per unit area than \*\*PERC 400-450W\*\* median (206.2 W/m²) - Temperature coefficient of -0.33%/°C matches the \*\*PERC 400-450W\*\* median - Bifacial design (70% factor) captures reflected light - adds 4-10% yield on ground-mount or white roof - In the top 70% for efficiency among all PERC panels ## Questions ### Are Sunova TS-BB54 (X Version, All Black) panels suitable for pitched roofs? Yes, the TS-BB54 All Black series is popular for pitched roofs thanks to its uniform black surface with no visible silver frame or white background between cells. The module blends well with dark roof tiles and standing seam metal roofing, and it can be installed on standard rail-mounting systems commonly used in Poland. ### What does bifacial technology add to the TS-BB54 panel, and is it worth paying extra for? Bifacial technology lets the module harvest additional energy from its rear side using light reflected off the surrounding surface. In practice this boosts yield, especially on light-colored roofs, white gravel, or ground-mounted installations elevated above the ground. On a typical dark pitched roof the effect is smaller but still measurable, so it's worth considering bifacial mainly for ground-mount and flat-roof installations. ### What warranty comes with Sunova TS-BB54 panels? The manufacturer offers a 25-year product warranty and a 25-year power output warranty, placing this series among modules with an extended coverage period compared to the standard 10-12 year product warranty offered by many competitors. This is a strong argument when choosing panels intended to run reliably for a quarter century. ### How do the PERC cells in the TS-BB54 differ from newer TOPCon technology? PERC cells, used in the TS-BB54 series, are a mature, proven technology offering a good price-to-efficiency ratio. TOPCon typically delivers higher efficiency and better high-temperature performance, but at a higher cost. Monocrystalline PERC with bifacial capability remains a solid choice for moderate-budget installations where the All Black look and predictable performance matter. ### What's the maximum power output of the Sunova TS-BB54, and how many panels are needed for a typical 6 kWp system? The highest-rated version in this series reaches 415 Wp. Building a system of roughly 6 kWp typically requires about 14-15 of these modules, depending on the exact inverter configuration and available roof area. ### Who manufactures the Sunova TS-BB54 panels, and is it a Tier 1 producer? TS-BB54 panels come from a manufacturer based in China, though the brand is not listed as Tier 1 under BloombergNEF's classification. This doesn't necessarily indicate lower technical quality, but it's worth reviewing warranty terms and the supplier's financial stability when choosing modules outside the Tier 1 group, especially for larger commercial installations. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/thornova-ts-bb54-400-415-x-all-black-2f2a9f263b1f.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | +50 W, +2.6 pp, +5 yr warranty | | [Just Solar JST-EDMH-(445-465)W-TD (460W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-460w-class) | 460 W | +50 W, +2.6 pp, +5 yr warranty | | [Luxor Solar LX-460M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-460m-182r-96-gg) | 460 W | +50 W, cooler, +2.6 pp | | [Philadelphia Solar PS-MNB108(HCBF)-460W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-460w) | 460 W | +50 W, +2.5 pp, +5 yr warranty | | [JA Solar JAT54S40-460/LR](https://comparepv.com/panel/ja-solar-jat54s40-460-lr) | 460 W | +50 W, cooler, +2.5 pp | | [Luxor Solar LX-460M/182R188-108+ GG](https://comparepv.com/panel/luxor-solar-lx-460m-182r188-108-gg) | 460 W | +50 W, +2.4 pp, +5 yr warranty | | [AIKO AIKO-455-MAH54Db](https://comparepv.com/panel/aiko-aiko-455-mah54db) | 455 W | Cooler, +2.3 pp, +5 yr warranty | | [Longi Solar LR5-54HTH-455M](https://comparepv.com/panel/longi-lr5-54hth-455m) | 455 W | +45 W, cooler, +2.3 pp | | [Sunova TS-BW54(400)](https://comparepv.com/panel/sunova-ts-bw54-400) | 400 W | -10 W, -0.5 pp | | [Sunova TS-BG54(405)-X](https://comparepv.com/panel/sunova-ts-bg54-405-x) | 405 W | Heavier, -0.3 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +100 W, cooler, +4.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +85 W, cooler, +3.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +80 W, cooler, +3.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +90 W, cooler, +3.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +90 W, cooler, +3.5 pp | --- Source: https://comparepv.com/panel/sunova-ts-bb54-410-x 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.
