The Ulica Solar Black Jade series is primarily elegance combined with state-of-the-art cell technology. These panels stand out with their deep black color, making them blend perfectly into modern roof architecture. Thanks to the use of N-type technology, the modules offer higher efficiency and better resistance to light-induced degradation, which translates into stable energy gains for decades. They solve the problem of aesthetics, which often conflicts with functionality, by providing a product of the highest visual class without compromising on power. Exceptional resistance to extreme weather conditions makes Black Jade panels a safe choice for installations exposed to strong winds or snow loads. This series is dedicated mainly to demanding private investors who care about the prestigious appearance of their home and maximizing self-consumption. Compared to the competition, Black Jade offers an excellent temperature coefficient, allowing for efficient operation even on hot days. Choosing this series is an investment in an innovative half-cut cell structure, which minimizes energy losses resulting from shading, ensuring smooth system operation in difficult installation conditions. This is a premium-class solution that effectively combines long-term durability with reliability.

Common questions

6 answered
What's the difference between TOPCon technology in Ulica Solar Black Jade panels and older PERC cells?
The N-type TOPCon cells used in the Black Jade series feature an additional passivation layer on the rear side of the cell, which reduces electron recombination and boosts efficiency compared to P-type PERC cells. In practice, this means higher power output from the same module area, lower light-induced degradation (LID), and more stable performance throughout the module's lifetime, even under the high temperatures typical of a sun-exposed roof in summer.
What warranty comes with the Ulica Solar Black Jade Series panels?
The manufacturer backs the Black Jade series with a 15-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. This means that after three decades of use, the panel should still deliver a guaranteed percentage of its initial rated power, making this series an attractive long-term investment for residential installations where a stable return over the panel's lifetime matters.
Are Black Jade panels bifacial, capturing extra energy from reflected light?
No, the Ulica Solar Black Jade series consists of monofacial panels. The manufacturer prioritized a uniform, deep-black front surface that blends aesthetically with roofs, at the cost of harvesting additional energy through the rear side. If maximizing yield for a ground-mount or facade installation is your priority, consider the bifacial counterparts of this series in the manufacturer's lineup.
What is the maximum power output of the Ulica Solar Black Jade series?
The top modules in the Black Jade series reach a maximum power of up to 505 Wp. Combined with a standard module footprint, this rating delivers a high power density per square meter of roof, which matters for single-family homes with limited roof area, where every extra watt from the same mounting space directly affects the achievable system size.
Can Ulica Solar Black Jade panels withstand strong wind and heavy snow loads?
Yes, the Black Jade modules are engineered for enhanced mechanical strength, backed by certified climate load ratings. They perform reliably in installations exposed to strong wind gusts and heavy winter snow accumulation, both common in the Polish climate. The reinforced frame and laminate structure minimize the risk of cell microcracks under high mechanical loads acting on the module surface.
Is Ulica Solar a Tier 1 manufacturer, and is it a trustworthy brand?
Ulica Solar is a Chinese PV module manufacturer operating since 2005, though it does not currently appear on the BloombergNEF Tier 1 list, a ranking based mainly on bank financing scale rather than product quality itself. In practice, Black Jade panels hold full IEC quality certifications and long-term warranties, making them a solid choice for residential installations at a reasonable price point.
