The Ulica Solar Black Jade-Flow (TOPCon N-type) 490-505W series is designed for investors who want to maximize energy production from a limited roof or ground-mounted surface, without compromising on durability. The use of TOPCon N-type cells helps maintain high efficiency over time and performs better in high-temperature conditions, which is particularly important in the summer on dark roof surfaces. A key feature of this series is Cutting Free technology - the non-cutting design reduces the risk of microcracks, ensuring long-term stability. Additionally, the modules have Anti-PID resistance, making them less susceptible to performance degradation in demanding installations and during long-term operation. The entire series is completed by sleek, aesthetic finish, which looks great on modern homes and premium buildings. This is a sensible choice for residential installations, small businesses, and projects where reliability, appearance, and predictable output are important.

Common questions

6 answered
Are Ulica Solar Black Jade-Flow panels bifacial, and is that worth paying for?
Yes, Black Jade-Flow modules use a double-glass bifacial construction - the rear side of the cells also captures light reflected off the roof, ground, or a bright surface. This delivers extra energy yield, especially on light-colored surfaces, ground-mount racking, or flat roofs with gravel or white PVC membranes. On a typical pitched roof with dark tiles the bifacial gain is smaller, but the dual-glass design still improves mechanical durability and long-term reliability.
What is Cutting Free technology in Ulica Solar panels, and is it worth choosing?
Cutting Free means the silicon cells are not laser-cut in half, unlike standard half-cut modules. This removes the risk of microcracks that form during the cutting process and can later develop into hot spots and power loss. As a result, the panel maintains a more stable energy yield throughout its lifetime, which matters especially given the 30-year linear power warranty offered on this series.
What warranty applies to Ulica Solar Black Jade-Flow panels?
The Black Jade-Flow series comes with a 15-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. That means the manufacturer guarantees a defined minimum power level even three decades into operation, which is standard for modern TOPCon N-type panels and helps you calculate long-term ROI more accurately.
Are the 505W Black Jade-Flow panels suitable for a small pitched roof?
Yes, the high per-module power (up to 505 Wp) makes this series well suited to limited roof space, since you can reach a higher system power with fewer panels. TOPCon N-type cell technology also handles high temperatures better on hot, sun-exposed, dark roof surfaces in summer, and the black finish blends well with the look of a typical pitched roof.
How do the TOPCon N-type cells in Black Jade-Flow differ from standard PERC cells?
TOPCon N-type cells have a lower temperature- and light-induced degradation rate than older P-type PERC cells, so they hold higher efficiency for longer, particularly in summer on a heated roof. These modules also feature Anti-PID resistance, meaning they're less prone to potential-induced degradation, which can be an issue in systems with higher system voltage or in humid climates.
Is Ulica Solar a Tier 1 manufacturer, and is it a trustworthy brand?
Ulica Solar is a Chinese manufacturer that is not currently on the BloombergNEF Tier 1 list, but it has been operating in the market for years and backs its modules with industry-standard warranties - 15 years on the product and 30 years on power output. Tier 1 status mainly reflects access to bank financing for utility-scale projects rather than module quality directly, so it shouldn't be the sole selection criterion for residential or small commercial installations.
