The **All Black** variant simplifies matching the panels to modern architecture and minimizes the visual "patchwork" effect on the roof. The use of **half-cut monocrystalline solar cells** helps to optimize module performance under partial shading and reduces internal losses, resulting in more stable production in real-world conditions. The TS-BB54 series is designed for **high resistance to typical environmental loads**, which is important in the Polish climate (wind, snow, temperature fluctuations). Another advantage is the availability of **bifacial** solutions within the TS-BB54 family, which can increase energy yield on roofs and ground-mounted structures. This is a good choice for single-family homes and small to medium-sized commercial installations, where a balance between appearance, reliability, and cost-effectiveness is important. ## Notable figures - 21.2% module efficiency - 0.6pp better than the \*\*PERC 400-450W\*\* median of 20.6% - Power density of 212.5 W/m² packs 6.3 W/m² more into the same footprint vs \*\*PERC 400-450W\*\* median (206.2 W/m²) - At -0.33%/°C, hot weather performance is typical for \*\*PERC 400-450W\*\* panels - Bifacial design (70% factor) captures reflected light - adds 4-10% yield on ground-mount or white roof - #8904 for efficiency, #8545 for temperature performance out of 14005 panels ## Questions ### Is the Sunova TS-BB54 (All Black) series still available for purchase? The TS-BB54 (All Black) series has been discontinued and is no longer offered as a current model. Panels still on the market are typically remaining warehouse stock. Check current availability with a distributor and consider newer series from the manufacturer if the installation timeline extends further out. ### What warranty comes with Sunova TS-BB54 panels? The manufacturer provides a 15-year product warranty and a 25-year power output warranty. This means protection against material and manufacturing defects for 15 years, plus a guaranteed level of energy generation performance over a quarter century, which is standard for modern monocrystalline panels. ### How do bifacial TS-BB54 panels differ from standard single-sided modules? Bifacial panels in the TS-BB54 family generate power from both sides of the module, capturing light reflected off the ground surface. On bright roofs, white gravel, or ground-mounted installations, this can boost total energy yield by several to over ten percent compared to a monofacial panel of the same nominal power. ### Do TS-BB54 All Black panels look good on a sloped single-family home roof? Yes, the All Black variant was specifically designed for the aesthetics of sloped single-family home roofs. The uniform black frame and backsheet eliminate the patchwork effect seen with standard white-backed panels, letting the array blend into the building's architecture without sacrificing energy performance. ### What are half-cut cells in the Sunova TS-BB54 and what benefits do they provide? Half-cut cells are standard monocrystalline cells cut in half, which reduces resistive losses and improves module behavior under partial shading, such as from a chimney or antenna. In practice, this results in more stable energy production under real-world conditions, not just under laboratory STC test parameters. ### How does the TS-BB54 series handle snow and wind loads in Poland's climate? The TS-BB54 design was engineered for enhanced mechanical resistance to typical environmental loads, including wind and snow, which matters given Poland's variable weather conditions. Before purchasing, it's still worth verifying the exact load ratings in the datasheet of the specific production batch. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/thornova-ts-bb54-400-415-all-black-a3b5c8a0dda1.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Just Solar JST-EDMH-(445-465)W-TD (465W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-465w-class) | 465 W | +50 W, +2.6 pp, +5 yr warranty | | [Luxor Solar LX-465M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-465m-182r-96-gg) | 465 W | +50 W, cooler, +2.6 pp | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | +45 W, +2.4 pp, +5 yr warranty | | [Luxor Solar LX-465M/182R188-108+ GG](https://comparepv.com/panel/luxor-solar-lx-465m-182r188-108-gg) | 465 W | +50 W, +2.4 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 | +45 W, +2.3 pp, +5 yr warranty | | [Luxor Solar LX-460M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-460m-182r-96-gg) | 460 W | Cooler, +2.3 pp, +5 yr warranty | | [Philadelphia Solar PS-MNB108(HCBF)-460W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-460w) | 460 W | +45 W, +2.3 pp, +5 yr warranty | | [JA Solar JAT54S40-460/LR](https://comparepv.com/panel/ja-solar-jat54s40-460-lr) | 460 W | Cooler, +2.2 pp, +5 yr warranty | | [Sunova TS-BW54(400)](https://comparepv.com/panel/sunova-ts-bw54-400) | 400 W | -15 W, -0.8 pp | | [Sunova TS-BG54(405)-X](https://comparepv.com/panel/sunova-ts-bg54-405-x) | 405 W | Heavier, -0.5 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +95 W, cooler, +3.8 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +80 W, cooler, +3.6 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +90 W, cooler, +3.4 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +75 W, cooler, +3.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +85 W, cooler, +3.2 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +85 W, cooler, +3.2 pp | --- Source: https://comparepv.com/panel/sunova-ts-bb54-415 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.
