The TOPCon N-TYPE Mono-Facial series from Ulica Solar provides a solution to the increasing demands of installations, where durability and long-term stability are paramount. By utilizing monocrystalline N-type cells and TOPCon technology, these modules exhibit significantly lower annual degradation compared to P-type based solutions - resulting in a demonstrably higher energy production over the long term. The series is distinguished by a cutting technology that minimizes micro-cracks, which reduces the risk of mechanical damage to the cells during production, directly impacting the module's reliability throughout its lifespan. The modules have undergone rigorous PID (Potential-Induced Degradation) resistance testing under hot and humid conditions (relative humidity of 85%) for 96 hours - making them exceptionally suitable for challenging climatic locations in Poland. Their exceptional mechanical strength - wind loads up to 3800 Pa and snow loads up to 5400 Pa - make them suitable for both rooftop installations on residential buildings and large-scale ground-mounted farms. The manufacturer offers a 15-year product warranty and a 30-year linear power warranty with a degradation rate not exceeding 0.4% per year.

Common questions

6 answered
How does the Ulica Solar TOPCon N-TYPE panel differ from standard P-type modules?
The N-type cells used in this series have significantly lower annual degradation than popular P-type PERC modules, resulting in higher energy yield over a 20-30 year horizon. TOPCon technology further boosts conversion efficiency through a passivation layer that reduces rear-surface losses on the cell. In practice, this means a panel that loses power more slowly and performs better in installations designed to last for decades.
What warranty comes with the Ulica Solar TOPCon 440-455W panels?
The manufacturer provides a 15-year product warranty along with a 30-year linear power warranty, with maximum degradation not exceeding 0.4% per year. This means that after 30 years of operation, the panel should still deliver a high percentage of its rated power, which is an important factor when calculating the long-term return on investment for a solar installation.
Are Ulica Solar TOPCon panels suitable for harsh climate conditions in Poland?
Yes, the modules passed a rigorous PID resistance test under damp heat conditions at 85% relative humidity for 96 hours, confirming their resistance to potential-induced degradation, which is common in humid climates. They also withstand wind loads up to 3800 Pa and snow loads up to 5400 Pa, making them well-suited for Polish winters with heavy snowfall and strong winds.
Will the TOPCon 440-455W series work on a sloped residential roof?
Yes, the high mechanical load resistance for wind and snow makes these panels well-suited for rooftop installations on residential buildings, including sloped roofs. With up to 455 Wp of power, the modules deliver high output from a limited roof area, which matters on the smaller roof surfaces typical of single-family homes.
What is the benefit of the micro-crack-free cutting technology in Ulica Solar panels?
The micro-crack-free cutting technology minimizes the risk of mechanical cell damage as early as the manufacturing stage. Micro-cracks caused by conventional laser cutting can lead to hot spots and accelerated power degradation over time. This technology helps the panel maintain higher reliability and stable performance throughout its service life, supporting the stated 30-year power warranty.
Are the TOPCon 440-455W Ulica Solar panels bifacial modules?
No, this series consists of mono-facial modules that generate energy only from the front side of the panel. This makes them simpler to install and price compared to bifacial modules, which require suitable mounting structures and a reflective ground surface to take advantage of rear-side gain. They perform reliably in standard rooftop and ground-mount installations without special albedo requirements.
