The use of **N-type TOPCon** cells results in more stable operation at high temperatures and reduced susceptibility to typical degradation mechanisms, ensuring that the installation maintains high productivity for longer. This is a practical solution for limited space - where every square meter counts, this series allows for increased production without the need for additional modules. Another key feature is the carefully designed construction for demanding conditions: a robust frame and components of high-quality, as well as **high mechanical strength**, which is essential for snow and wind loads. The modules offer **long warranties** and predictable performance over time, making it easier to calculate the overall cost-effectiveness. This is a good choice for premium home installations, businesses, and service facilities, where **high efficiency**, reliability, and low energy costs throughout the system's lifespan are key. ## Notable figures - At 23.0% efficiency, this panel is 0.5pp above typical \*\*TOPCon 450-500W\*\* modules (median: 22.5%) - 230.3 W/m² power density - 5.1 W/m² more than \*\*TOPCon 450-500W\*\* median (225.2 W/m²), more power per roof area - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 450-500W\*\* median - Weight of 21.5 kg (2.5 kg below \*\*TOPCon 450-500W\*\* median of 24.0 kg) allows easier transport and roof mounting - #1744 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### What is TOPCon technology and how does it differ from classic PERC cells? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology where a thin tunnel oxide and doped silicon layer reduce energy losses on the rear side of the cell. Compared to popular P-type PERC cells, this results in higher conversion efficiency, a smaller power drop at high temperatures, and slower degradation over time. In the Ulica Solar 460-475W series, this means more energy yield from the same roof area compared to equivalent PERC modules. ### What warranty comes with the Ulica Solar TOPCon 460-475W series? The manufacturer offers a 15-year product warranty covering material and workmanship defects, plus a 30-year power output warranty guaranteeing a minimum energy production level over that period. This warranty structure is typical for modern N-type modules and helps investors calculate return on investment over several decades, since power degradation over time is predictable and contractually guaranteed. ### Are Ulica Solar TOPCon 460-475W panels a good fit for limited roof space? Yes, that's one of this series' main strengths. Up to 475 Wp per module means the same number of panels generates more energy than older, lower-power models. For roofs with a fixed maximum number of panels due to space constraints, this lets you increase total system output without expanding the mounting area. ### Do Ulica Solar TOPCon modules perform well in high summer temperatures? Yes, one of the key advantages of N-type TOPCon technology over traditional P-type cells is a lower temperature coefficient of power, meaning a smaller efficiency drop during heat waves. In practice, this means the system loses less power on hot, sunny days compared to older PERC panels, resulting in higher real-world energy yield during summer months when irradiance is highest. ### Is Ulica Solar a tier 1 manufacturer, and does that matter when choosing panels? Ulica Solar is not currently on the BloombergNEF tier 1 list, a classification that mainly reflects the scale of bank financing rather than technical product quality. The company is headquartered in China with years of experience manufacturing PV modules. Tier 1 status tends to matter most for large commercial projects financed by bank loans, while for residential or business installations, technical parameters, certifications, and warranty terms are typically more relevant. ### Are the Ulica Solar TOPCon 460-475W panels bifacial? No, this specific series consists of monofacial modules optimized for maximum power output from the front side only. They do not capture additional reflected light on the rear side, unlike bifacial modules. This is standard for typical roof-mounted installations, where the rear side of the panel has no exposure to reflected light anyway, so bifacial technology wouldn't provide extra benefit. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ulica-mono-n-type-topcon-1800mm-460-475w-mono-facial-silver-8a298a8b5c90.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +40 W, cooler, +2.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +25 W, cooler, +1.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +35 W, cooler, +1.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +20 W, cooler, +1.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +30 W, cooler, +1.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +30 W, cooler, +1.5 pp | | [Ulica Solar UL-460M-108CHVN](https://comparepv.com/panel/ulica-solar-ul-460m-108chvn) | 460 W | -10 W, -0.5 pp | | [Ulica Solar UL-465M-108CHVN](https://comparepv.com/panel/ulica-solar-ul-465m-108chvn) | 465 W | -0.2 pp | | [Ulica Solar UL-475M-108CHVN](https://comparepv.com/panel/ulica-solar-ul-475m-108chvn) | 475 W | +0.2 pp | --- Source: https://comparepv.com/panel/ulica-solar-ul-470m-108chvn Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
