The use of **N-type cell technology** eliminates the key problem of LID degradation, which, combined with the innovative TOPCon structure, provides users with significantly higher energy yields per square meter. These modules stand out with excellent efficiency in low irradiation conditions, which directly translates into the financial stability of investments in the Polish climate. A key benefit for the investor is the drastic **optimization of BOS costs** - thanks to the impressive unit power, fewer mounting structures and less cabling are required. What sets this series apart from competing products is the **exceptionally low temperature coefficient**, which minimizes power losses during hot summers, and high resistance to extreme weather conditions. These modules also offer excellent **bifacial generation capability**, allowing for additional energy gain from radiation reflected from the ground. This is a solution dedicated to professionals striving to **maximize ROI**, offering durability confirmed by a long-term linear performance warranty, making these panels one of the most cost-effective choices in the premium segment for modern industrial projects. ## Notable figures - Efficiency of 22.7% matches the \*\*TOPCon 700-750W\*\* median - Power density of 226.9 W/m² is 3.2 W/m² below \*\*TOPCon 700-750W\*\* median (230.2 W/m²) - needs more roof space - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 700-750W\*\* median - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - In the top 24% for efficiency among all TOPCon panels ## Questions ### What is TOPCon N-Type technology in the Ulica Solar 700-715W series and how does it differ from classic P-Type cells? The N-type cells used in this series eliminate LID (Light Induced Degradation), a common issue in older P-type PERC technology. Thanks to the tunnel oxide passivated contact (TOPCon) layer, module efficiency reaches up to 23%, and annual power degradation is lower, resulting in higher energy yield over the system's lifetime - especially significant for large-scale PV farms. ### Are the Ulica Solar TOPCon 700-715W panels suitable for mounting on a single-family home roof? This is not the optimal choice for a typical pitched residential roof. The panels measure 2384x1303 mm and weigh about 37.4 kg, requiring reinforced mounting structures and a larger installation area. This series is designed for utility-scale PV plants and large commercial installations, where high unit power reduces the number of modules, cabling, and racking needed per megawatt. ### What warranty comes with the Ulica Solar TOPCon N-Type 700-715W panels? The manufacturer provides a 15-year product warranty along with a 30-year linear power output warranty. This means annual power degradation is guaranteed to stay within a low, predictable range throughout the entire period, helping investors accurately forecast ROI in utility-scale projects. ### How much extra energy does the bifacial design of this series provide? The bifacial construction allows the module to generate power from its rear side using light reflected off the ground. Depending on the albedo of the surface (e.g., light gravel or white roofing membrane) and the mounting height above grade, the additional energy gain can range from a few to over ten percent compared to a monofacial module of the same rated power. ### How do the TOPCon 700-715W panels perform in high temperatures, such as during Polish summers? This series has a power temperature coefficient of -0.29%/°C, noticeably better than typical PERC modules, which are usually around -0.35 to -0.40%/°C. In practice, this means smaller energy production losses on hot days, when panel surface temperature significantly exceeds the 25°C STC reference condition. ### Is Ulica Solar a tier 1 manufacturer, and are the panels easy to finance through a bank or leasing company? Ulica Solar is not listed as a tier 1 manufacturer under the BNEF classification, despite holding IEC and TUV certifications and having an established export presence from China. In practice, for larger projects financed through a bank loan or leasing, it's worth checking the specific lender's policy toward non-tier-1 manufacturers in advance, as some institutions may require additional risk assessment. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ulica-solar-n-topcon-2384mm-700-715w-bifacial-glass-33mmfram-f3152145389b.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, lighter, +2.5 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | -30 W, lighter, +2.3 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, lighter, +2.3 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, lighter, +2.2 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | -35 W, lighter, +2.1 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | -35 W, lighter, +2.1 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | -35 W, lighter, +2.1 pp | | [Ulica Solar UL-655M-132DG](https://comparepv.com/panel/ulica-solar-ul-655m-132dg) | 655 W | -50 W, hotter, -1.6 pp | | [Ulica Solar UL-660M-132DG](https://comparepv.com/panel/ulica-solar-ul-660m-132dg) | 660 W | -45 W, hotter, -1.4 pp | | [Ulica Solar UL-665M-132HV](https://comparepv.com/panel/ulica-solar-ul-665m-132hv) | 665 W | Hotter, -1.3 pp, -5 yr warranty | | [Ulica Solar UL-670M-132DG](https://comparepv.com/panel/ulica-solar-ul-670m-132dg) | 670 W | -35 W, hotter, -1.1 pp | | [Ulica Solar UL-700M-132DGN](https://comparepv.com/panel/ulica-solar-ul-700m-132dgn) | 700 W | Very close match | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +100 W, cooler, +2.4 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +95 W, cooler, +2.2 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +90 W, cooler, +2.1 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +85 W, cooler, +1.9 pp | --- Source: https://comparepv.com/panel/ulica-solar-ul-705m-132dgn Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
