The use of **n-type TOPCon cells** results in low initial degradation and very good long-term parameter repeatability, which facilitates precise energy production planning in commercial projects. These are **bifacial** modules that can recover additional light from the rear side - particularly on a reflective surface or with an appropriately designed structure. The **glass-glass** construction enhances resistance to weather conditions and reduces the risk of microcracks in demanding locations, while also supporting long-term durability. In practice, this series addresses common issues associated with large-scale investments: limited surface area, energy losses due to heat, and the need for reliable operation in harsh environments. Another key advantage is **PID resistance**, which is important where the stability of the entire string is paramount. They are best suited for PV farms, industrial rooftops, and C&I projects focused on long-term returns. ## Notable figures - Module efficiency of 22.2% is 0.6pp below average for \*\*TOPCon 600-650W\*\* panels (median: 22.8%) - 222.1 W/m² power density is 5.6 W/m² below \*\*TOPCon 600-650W\*\* median (227.7 W/m²) - requires larger installation area - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 600-650W\*\* median - In the top 41% for efficiency among all TOPCon panels ## Questions ### What warranty comes with the Ulica Solar TOPCon 600-615W series? The series is covered by a 15-year product warranty and a 30-year linear power output warranty. This means the manufacturer guarantees a defined performance level over three decades, which is standard for modern n-type TOPCon cells and helps with ROI planning in commercial projects and utility-scale PV farms. ### How do N-Type TOPCon cells differ from standard PERC cells? N-type TOPCon cells have lower initial degradation and a slower power decline over the years compared to PERC. The additional passivation layer reduces recombination losses, resulting in higher module efficiency and more stable output at high temperatures - important during periods of intense summer sun. ### How much extra energy does bifacial technology add in this series? Bifacial modules capture part of the light reflected off the surface beneath the panel, boosting energy yield compared to a monofacial module of the same rated power. The effect is strongest over bright, reflective surfaces (e.g., white gravel, reflective roofing) and with elevated mounting structures, making rack selection an important factor. ### Are these panels PID-resistant and suitable for large PV farms? Yes, the modules are PID (Potential Induced Degradation) resistant, meaning they resist power loss caused by voltage differences within a string. This matters for large ground-mount installations and C&I roofs, where long strings generate higher system voltages. The glass-glass construction also improves mechanical and climate resistance in such environments. ### Is Ulica Solar a Tier 1 manufacturer? Ulica Solar is not currently listed as a Tier 1 manufacturer under BloombergNEF's classification, although it is an established Chinese PV module maker with a solid market presence. Tier 1 status mainly reflects financial standing and supply history with large bankable projects, not the quality of the product itself. ### What kind of installations is the TOPCon 600-615W series best suited for? The series is built for large commercial and industrial installations - PV farms, industrial and warehouse rooftops, and C&I projects focused on maximizing yield from limited space. The high unit power of up to 615 Wp reduces the module count and simplifies wiring in large-scale systems. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ulica-mono-n-type-topcon-2382mm-600-615w-bifacial-glass-2408-45f45413fe85.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +50 W, lighter, +3.0 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +45 W, lighter, +2.8 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -40 W, lighter, +2.6 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +40 W, lighter, +2.6 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -45 W, lighter, +2.4 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +35 W, lighter, +2.4 pp | | [Ulica Solar UL-605M-156ADGN](https://comparepv.com/panel/ulica-solar-ul-605m-156adgn) | 605 W | Very close match | | [Ulica Solar UL-610M-156ADGN](https://comparepv.com/panel/ulica-solar-ul-610m-156adgn) | 610 W | +10 W, +0.4 pp | | [Ulica Solar UL-615M-156ADGN](https://comparepv.com/panel/ulica-solar-ul-615m-156adgn) | 615 W | +15 W, +0.5 pp | | [Ulica Solar UL-630M-144CDGN](https://comparepv.com/panel/ulica-solar-ul-630m-144cdgn) | 630 W | +30 W, +1.1 pp | | [Ulica Solar UL-635M-144CDGN](https://comparepv.com/panel/ulica-solar-ul-635m-144cdgn) | 635 W | +35 W, +1.3 pp | | [Ulica Solar UL-640M-144CDGN](https://comparepv.com/panel/ulica-solar-ul-640m-144cdgn) | 640 W | +40 W, +1.5 pp | | [Ulica Solar UL-645M-144CDGN](https://comparepv.com/panel/ulica-solar-ul-645m-144cdgn) | 645 W | +45 W, +1.7 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +80 W, lighter, +3.0 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +75 W, lighter, +2.8 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +100 W, cooler, +2.8 pp | --- Source: https://comparepv.com/panel/ulica-solar-ul-600m-156adgn 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.
