The Ulica Solar TSM144-9-570-595BNDG series is designed for high yields on large rooftops and PV farms, where every square meter counts, and reliable performance over many years is essential. The use of N-type TOPCon cells results in improved resistance to aging and higher efficiency in real-world conditions, especially at elevated temperatures. The bifacial construction allows for the recovery of additional energy from reflections from the ground, which is a significant advantage on ground-mounted systems, transparent roof membranes, and carport structures.

The double glass variant enhances resistance to moisture, microcracks, and mechanical loads, making it suitable for safe operation in more challenging environments. Another key advantage is PID resistance, which limits the risk of power drops in installations operating at high voltages. This series is a good choice if the priority is lower energy costs over the lifetime of the installation, as well as the certainty of production under varying lighting conditions.

Common questions

6 answered
What is N-type TOPCon technology in the Ulica Solar TSM144-9-570-595BNDG series, and how does it differ from standard P-type cells?
TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology with an added passivation layer that reduces electron recombination at the cell surface. In practice this means higher efficiency, lower annual degradation, and better performance at elevated temperatures compared to classic P-type PERC cells. For the end user, this translates into higher lifetime energy yield, especially in summer when modules run hot.
Do bifacial panels in the TSM144-9-570-595BNDG series really produce more energy, or is it just marketing?
The actual gain depends heavily on the installation site. On PV farms, carports, and light-colored roofing membranes, where the rear side receives reflected light, the extra yield can range from a few percent up to double digits compared to a monofacial panel of the same rated power. On a typical pitched roof, where the panel's back sits close to the structure, the bifacial effect is negligible and the advantage isn't fully realized.
What warranty comes with the Ulica Solar TSM144-9-570-595BNDG series?
The manufacturer offers a 5-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. This means that after 30 years of operation, the panel is expected to still deliver a significant share of its original rated power. Buyers should check the current warranty card with their distributor, as detailed terms can vary by market.
Does the glass-glass construction in this series require special mounting?
Double glass panels are heavier than standard modules with a polymer backsheet, so it's important to check the mounting structure's load capacity and use the clamps and torque values recommended by the manufacturer. Otherwise, they install on standard framed-module racking systems. In exchange, you get higher resistance to moisture, microcracks, and mechanical loads, which matters under strong sun exposure and wind.
Are the TSM144-9-570-595BNDG panels suitable for a residential pitched roof?
This series is optimized mainly for large commercial roofs, PV farms, and carports, where maximizing power per square meter and leveraging the bifacial effect matter most. With power ratings up to 595 Wp, these modules are larger and heavier than panels typically designed for single-family homes, so before installing on a residential pitched roof, consult an installer about roof structure load capacity and compatibility with standard residential mounting systems.
Is Ulica Solar a Tier 1 manufacturer, and does that matter when choosing panels?
Ulica Solar is not currently listed as Tier 1 under BloombergNEF's classification, which is based mainly on the scale of bankable project financing rather than product quality directly. In practice, the company is an established Chinese manufacturer with its own N-type TOPCon cell production lines. Tier 1 status can matter when securing bank financing for a large installation, but it doesn't by itself determine a panel's quality or durability.
