These are black-colored modules with a refined finish that complement modern architecture and make it easier to meet the requirements of investors who value a consistent design. The use of **N-type (TOPCon) cells** helps to minimize degradation over time and improves stability in challenging conditions, such as high temperatures or variable sunlight. The **bifacial** design also allows for the use of light from the back side, which is particularly beneficial on bright roofs and in installations with appropriate reflection. Thanks to the **positive power tolerance**, it is easier to predict and optimize the profitability. This is a good choice for single-family homes and small commercial buildings when you need a **compact format** that makes it easier to design strings and install on a limited area. ## Notable figures - Efficiency of 21.2% is 0.8pp below the \*\*TOPCon 400-450W\*\* median (22.0%) - 212.5 W/m² power density is 7.7 W/m² below \*\*TOPCon 400-450W\*\* median (220.2 W/m²) - requires larger installation area - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 400-450W\*\* median - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces - In the top 64% for efficiency among all TOPCon panels ## Questions ### How does the bifacial technology in Sunova TS-BBT54 All Black panels differ from standard mono-facial modules? TS-BBT54 bifacial modules have active cells on both sides, so besides direct sunlight they also capture light reflected off the roof or ground surface. On bright, reflective surfaces this can add several percent or more of extra energy compared to a mono-facial panel with the same nominal power rating. The biggest gain shows up on white roofing or light-colored gravel installations. ### Do TOPCon cells in the TS-BBT54 series perform well on roofs that heat up in summer? Yes, N-type TOPCon cells have a better power temperature coefficient than older P-type technology, meaning less output loss as the panel gets hot. TOPCon also virtually eliminates light-induced degradation (LID), so the module keeps stable energy production even after years of operation in hot climates or poorly ventilated roof sections. ### What warranty comes with Sunova TS-BBT54 All Black panels? The manufacturer offers a 15-year product warranty along with a 30-year power output warranty, which is standard for modern N-type modules. In practice this means the panel should still deliver a significant share of its initial power after 30 years, making it easier to plan long-term return on investment, especially for installations financed with a loan or subsidy. ### Are TS-BBT54 All Black panels suitable for a small single-family house roof? Yes, the series was designed with a compact format in mind, making string layout easier on limited pitched-roof surfaces. With up to 430 Wp of power and a full-black aesthetic, the module blends well with modern architecture while fitting more panels on a smaller roof section than larger-format modules would allow. ### Is Sunova a Tier 1 manufacturer, and where are TS-BBT54 panels made? Sunova is not on the Tier 1 list according to BloombergNEF classification, which doesn't mean lower quality but rather a shorter track record of financing large-scale projects. The panels are manufactured in China, where the company runs its own N-type TOPCon production lines. This is worth checking if your project financing requires panels from a Tier 1 list. ### What does positive power tolerance mean on TS-BBT54 panels, and why does it matter? Positive power tolerance means the actual panel output never falls below the rated label value and often slightly exceeds it. This lets installers and investors more accurately predict real energy yield during system design, avoiding the risk of underestimating string output, which makes it easier to close the profitability balance and size the inverter correctly. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/thornova-ts-bbt54-410-430-all-black-fe9979248f7f.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, lighter, +2.6 pp | | [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, cooler, +2.4 pp | | [Luxor Solar LX-465M/182R188-108+ GG](https://comparepv.com/panel/luxor-solar-lx-465m-182r188-108-gg) | 465 W | +50 W, heavier, +2.4 pp | | [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, lighter, +2.3 pp | | [Luxor Solar LX-460M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-460m-182r-96-gg) | 460 W | +45 W, cooler, +2.3 pp | | [Philadelphia Solar PS-MNB108(HCBF)-460W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-460w) | 460 W | +45 W, cooler, +2.3 pp | | [JA Solar JAT54S40-460/LR](https://comparepv.com/panel/ja-solar-jat54s40-460-lr) | 460 W | +45 W, cooler, +2.2 pp | | [Sunova TS-BW54(400)](https://comparepv.com/panel/sunova-ts-bw54-400) | 400 W | Hotter, -0.8 pp, -5 yr warranty | | [Sunova TS-BG54(405)-X](https://comparepv.com/panel/sunova-ts-bg54-405-x) | 405 W | Hotter, heavier, -0.5 pp | | [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-bbt54-415 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.
