This innovative architecture allows for a significant reduction in energy losses resulting from internal resistance, which directly translates into higher power yields even during intense heating of the modules. A key benefit for the user is **exceptional resistance to partial shading**, as dividing the panel into two independent sections ensures that shade falling on the lower part does not block the operation of the entire unit. PERC technology and the use of multi-busbars (MBB) guarantee **excellent efficiency in low-light conditions**, making these panels an ideal choice for Polish weather conditions, including cloudy and rainy days. This series solves the problems of homeowners with complex roof geometries and investors looking for solutions with **above-average mechanical durability**, resistant to extreme snow loads or strong winds. They are distinguished from the competition by rigorous Anti-PID protection and certified resistance to salt and ammonia corrosion. By choosing these modules, you invest in **maximum energy yield per square meter** and system stability for decades, ensuring a quick return on investment in both the residential and industrial sectors. This technology was created for those who prioritize **reliability in difficult environmental conditions**. ## Notable figures - At 20.2% efficiency, this panel is 4.2pp above typical \*\*TOPCon 0-400W\*\* modules (median: 16.0%) - Power density of 202.3 W/m² packs 42.5 W/m² more into the same footprint vs \*\*TOPCon 0-400W\*\* median (159.8 W/m²) - -0.36%/°C temperature coefficient - 0.07pp worse than \*\*TOPCon 0-400W\*\* median (-0.29%/°C), expect higher hot weather losses - 21.8 kg weight - 1.7 kg lighter than \*\*TOPCon 0-400W\*\* median (23.5 kg), reducing installation effort - #11899 for efficiency, #12345 for temperature performance out of 14005 panels ## Questions ### What is the maximum power output of the Ulica Solar MONO HALF-CUT MODULE series? Panels in this series reach up to 405 Wp maximum power. This is achieved through half-cut TOPCon cells, which reduce resistive losses and increase energy yield compared to conventional full-cell modules of similar dimensions. ### Is the Ulica Solar MONO HALF-CUT MODULE series still available for purchase? No, production of this series has ended and the model has been discontinued from the manufacturer's current lineup. Panels may still be found through distributors as remaining stock, but buyers should check the manufacturing date and confirm warranty service availability before choosing this option over a currently produced model. ### What warranty applies to the Ulica Solar MONO HALF-CUT MODULE panels? The manufacturer provides a 12-year product warranty covering material and workmanship defects, along with a 25-year power output warranty. Since the series has been discontinued, processing warranty claims may become harder over time, so it's advisable to confirm after-sales support terms with the seller before purchasing. ### How do half-cut cells in this series differ from standard full cells? Half-cut cells split the panel into two electrically independent sections, so shading on part of one half doesn't disable the entire module but only reduces output in that section. Smaller cells also generate lower current losses and heat buildup, resulting in higher energy yield, particularly under partial shading from chimneys or antennas. ### Are Ulica Solar MONO HALF-CUT MODULE panels suitable for roofs with complex geometry? Yes, the half-cut cell design handles partial shading well, making these panels a good fit for roofs with dormers, chimneys, or irregular pitch angles where shading is common. A reinforced frame also provides mechanical resistance to snow and wind loads, making them a versatile choice for more challenging roof structures. ### Is Ulica Solar a Tier 1 manufacturer, and does that matter when choosing panels? No, Ulica Solar, a China-based manufacturer, is not listed as a Tier 1 producer under BloombergNEF's classification. This doesn't necessarily indicate lower technical quality, but it signals lower financial stability and bankability in the eyes of lenders, which is worth considering for commercial projects financed through bank loans. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Ulica-Mono-182mm-10BB-HC-400M-108-Full-Black-20228-d791265a0ec7.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Luxor Solar LX-440M/182-108+GG](https://comparepv.com/panel/luxor-solar-lx-440m-182-108-gg) | 440 W | Cooler, +2.8 pp, +5 yr warranty | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +2.8 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | Lighter, +2.8 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | Lighter, +2.8 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | Lighter, +2.8 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | Lighter, +2.8 pp, +5 yr warranty | | [Jetion JT440SYK(B)](https://comparepv.com/panel/jetion-jt440syk-b) | 440 W | Cooler, +2.7 pp, +5 yr warranty | | [Luxor Solar LX-440M/182-108+](https://comparepv.com/panel/luxor-solar-lx-440m-182-108) | 440 W | +45 W, cooler, +2.6 pp | | [Ulica Solar UL-400M-108HV](https://comparepv.com/panel/ulica-solar-ul-400m-108hv) | 400 W | +0.2 pp | | [Ulica Solar UL-405M-108HV](https://comparepv.com/panel/ulica-solar-ul-405m-108hv) | 405 W | +10 W, +0.5 pp | | [Ulica Solar UL-430M-108ADGN](https://comparepv.com/panel/ulica-solar-ul-430m-108adgn) | 430 W | Cooler, +1.8 pp, +5 yr warranty | | [Ulica Solar UL-435M-108ADGN](https://comparepv.com/panel/ulica-solar-ul-435m-108adgn) | 435 W | Cooler, +2.1 pp, +5 yr warranty | | [Ulica Solar UL-440M-108ADGN](https://comparepv.com/panel/ulica-solar-ul-440m-108adgn) | 440 W | Cooler, +2.3 pp, +5 yr warranty | | [Ulica Solar UL-445M-108ADGN](https://comparepv.com/panel/ulica-solar-ul-445m-108adgn) | 445 W | +50 W, cooler, +2.6 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +115 W, cooler, +4.8 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +100 W, cooler, +4.6 pp | --- Source: https://comparepv.com/panel/ulica-solar-ul-395m-108hv Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
