These panels stand out with their exceptional Full Black aesthetics, making them an ideal choice for investors who value a consistent design for modern residential buildings. Thanks to an innovative construction, the modules effectively minimize energy losses resulting from periodic shading and high ambient temperatures, which directly translates to **higher efficiency throughout the entire life cycle of the installation**. They solve the common problem of rapid power degradation, offering significantly better long-term stability than traditional older-type modules. This series is specifically dedicated to single-family homeowners looking for an uncompromising combination of elegance and maximum gains from electricity production. What distinguishes the Black Jade-Flow line from the competition is its **optimized energy flow** and high power density while maintaining standard dimensions, which facilitates installation on limited roof surfaces. Investing in these modules is a guarantee of energy security thanks to **low light-induced degradation** and excellent resistance to extreme weather conditions. By choosing this solution, the user receives a premium-class product that effectively combines innovative materials engineering with an impeccable appearance, realistically increasing the market value of any modern property. ## Notable figures - Efficiency of 22.8% matches the \*\*TOPCon 450-500W\*\* median - At 227.7 W/m² power density, roof space requirements are typical for \*\*TOPCon 450-500W\*\* panels - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 450-500W\*\* panels - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof - In the top 22% for efficiency among all TOPCon panels ## Questions ### How does N-type TOPCon technology in the Black Jade-Flow series differ from standard PERC cells? N-type TOPCon cells used in the Black Jade-Flow series deliver higher efficiency (up to about 23%) and a significantly lower annual degradation rate than traditional P-type PERC cells. Thanks to an additional passivation layer, these modules handle high temperatures and partial shading better, resulting in higher energy yield under demanding conditions, especially during summer and at low sun angles. ### Are Black Jade-Flow panels bifacial, and how much extra energy can that generate? Yes, Black Jade-Flow modules use a bifacial construction with a glass rear layer, allowing them to capture reflected radiation from the back side of the panel as well. Depending on ground albedo (e.g., a light-colored roof, gravel, or snow), the additional energy gain can range from a few to over ten percent compared to a standard monofacial panel of the same 460 Wp rated power. ### What warranty does Ulica Solar offer on the Black Jade-Flow series? Ulica Solar provides a 15-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. This means that after 30 years of operation the panel should retain around 87% of its initial power output, a typical result for modern N-type TOPCon cells with low light-induced degradation. ### Are Black Jade-Flow panels suitable for a pitched roof on a single-family home? Yes, the Black Jade-Flow series, rated up to 460 Wp with a Full Black aesthetic, is designed for pitched-roof installations on single-family homes where both appearance and performance matter. Standard module dimensions make installation on typical rafter structures straightforward, and the high power density allows for greater system output on limited roof space. ### Is Ulica Solar a Tier 1 manufacturer, and can this brand be trusted? Ulica Solar is not currently listed as a Tier 1 manufacturer under the Bloomberg NEF classification, but it is an experienced Chinese solar panel maker with many years on the market, offering full IEC certification and standard warranties (15/30 years) comparable to higher-tier brands. Tier 1 status mainly reflects a company's financial stability rather than the technical quality of the module itself. ### What does 'optimized energy flow' mean for Black Jade-Flow panels, and how does it affect power output? This term refers to a module design that minimizes energy losses from internal resistance and uneven cell heating, a common issue under variable irradiance conditions. In practice, this results in more stable daily energy production, reduced losses during partial shading, and higher efficiency over the entire lifespan of the installation compared to older module types. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ulica-mono-n-type-topcon-1762mm-445-460w-bifacial-black-jade-be9f53c1d291.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +40 W, lighter, +2.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +50 W, cooler, +1.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +35 W, lighter, +1.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +45 W, cooler, +1.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +45 W, cooler, +1.7 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +45 W, cooler, +1.7 pp | | [Ulica Solar UL-440M-108BHVN](https://comparepv.com/panel/ulica-solar-ul-440m-108bhvn) | 440 W | -15 W, lighter, -0.8 pp | | [Ulica Solar UL-445M-108BDGN](https://comparepv.com/panel/ulica-solar-ul-445m-108bdgn) | 445 W | -10 W, -0.5 pp | | [Ulica Solar UL-450M-108BDGN](https://comparepv.com/panel/ulica-solar-ul-450m-108bdgn) | 450 W | -0.2 pp | | [Ulica Solar UL-460M-108BDGN](https://comparepv.com/panel/ulica-solar-ul-460m-108bdgn) | 460 W | +0.2 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/ulica-solar-ul-455m-108bdgn 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.
