This means a larger mounting area is needed to reach the same system power. - **Inconsistency in bifacial data** - The series description emphasizes double-sided output and 45% rear transparency, while the technical data flags is\_bifacial as false. This discrepancy could complicate yield modeling (e.g., in PVsyst) and should be verified with the manufacturer before quoting the product. - **Wide spread in product warranty** - Product warranty ranges from 12 to 25 years across the 11 available variants, meaning some models in the series offer only a basic 12-year coverage period — significantly below the 25-year premium standard common in this segment. ## About this series The UNICA series from PVolution consists of bifacial double-sided modules built on TOPCon technology, engineered for ground-mount, utility-scale, and agrivoltaic installations where maximizing output per square meter of land truly matters. With **45% rear-side transparency**, the panel lets a portion of sunlight pass through to the ground below, enabling energy generation to coexist with crop farming or grazing beneath the array - a true case of **dual land use** that is especially valuable to agri-energy investors. High-efficiency **TOPCon** cells deliver stable performance even under diffuse light and elevated temperatures, while the module's build offers **high mechanical load resistance** against snow and wind, an important advantage on more demanding terrain. Designed in Germany and manufactured at a facility listed on the Bloomberg NEF Tier 1 list, UNICA is well suited to bank-financed commercial and industrial-scale projects. A linear power warranty spanning three decades, backed by a German manufacturer warranty reinsured through a third-party insurer, gives investors an added layer of security. UNICA is the right fit wherever **increased land productivity** needs to be balanced with the site's existing functional use. ## Questions ### How does the UNICA series differ from standard monofacial panels? UNICA is a bifacial module that, thanks to 45% rear-side transparency, lets part of the light pass through to the ground. A standard monofacial panel only generates power from one side, whereas UNICA also captures light reflected off the ground and allows crops to grow or livestock to graze beneath the array - true dual land use on the same plot. ### Are UNICA panels suitable for agri-PV installations? Yes, this is the series' primary use case. The partial transparency of the rear side lets light reach crops or grass under the panels, so the same plot can generate electricity and support farming simultaneously. The module also has strong mechanical resistance to snow and wind loads, important for open-field sites. ### What warranty does UNICA come with, and is it financially backed? The manufacturer offers a 25-year product warranty and a linear power warranty spread over 30 years. The German manufacturer's warranty is additionally reinsured by a third-party insurer, meaning payout doesn't depend solely on the manufacturer's financial health - an important safeguard for long-term projects. ### What is TOPCon cell technology in UNICA, and does it deliver real-world performance gains? TOPCon is a high-efficiency cell technology that handles losses from high temperature and diffuse light better than older PERC technology. The module reaches up to 370 Wp and maintains stable output even under less-than-ideal irradiance, translating into higher annual energy yield in practice. ### Can UNICA panels be bank-financed for a large ground-mount installation? Yes, the modules come from a factory listed on Bloomberg NEF's Tier 1 list, one of the criteria banks and lenders use when assessing risk for commercial and industrial projects. This makes it easier to secure bank financing for larger ground-mount and utility-scale installations built with this series. ### Where is UNICA not the right choice? UNICA was designed for ground-mount and agri-PV installations, where the bifacial gain and dual land use are key benefits. On pitched roofs or facades, where there is no reflected light from the ground below, the bifaciality advantage is largely lost, so a dedicated rooftop series would be a better fit there. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/UNICA345-365N108M10ORANGE-1-8b3822050de8.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-300MH-72](https://comparepv.com/panel/ja-solar-ns-300mh-72) | 300 W | -45 W, lighter, +5.6 pp | | [PolyCrown Solar Tech NS-300MH-72](https://comparepv.com/panel/polycrown-solar-tech-ns-300mh-72) | 300 W | -45 W, lighter, +5.6 pp | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | -15 W, lighter, +5.4 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | -15 W, lighter, +5.4 pp | | [Gamko New Energy GKA182M300W](https://comparepv.com/panel/gamko-new-energy-gka182m300w) | 300 W | -45 W, +5.3 pp, +5 yr warranty | | [Gamko New Energy GKA210M320W](https://comparepv.com/panel/gamko-new-energy-gka210m320w) | 320 W | Lighter, +5.3 pp, +5 yr warranty | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | Lighter, +5.3 pp, +5 yr warranty | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +5.3 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 | +35 W, +5.3 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 | +35 W, +5.3 pp, +5 yr warranty | | [PVolution PVN350-M10TCBB (ORANGE)](https://comparepv.com/panel/pvolution-pvn350-m10tcbb-orange) | 350 W | Very close match | | [PVolution PVN355-M10TCBB (ORANGE)](https://comparepv.com/panel/pvolution-pvn355-m10tcbb-orange) | 355 W | +10 W, +0.5 pp | | [PVolution PVN360-M10TCBB (ORANGE)](https://comparepv.com/panel/pvolution-pvn360-m10tcbb-orange) | 360 W | +15 W, +0.7 pp | | [PVolution PVN365-M10TCBB (ORANGE)](https://comparepv.com/panel/pvolution-pvn365-m10tcbb-orange) | 365 W | +20 W, +1.0 pp | | [PVolution PVN435-M10TCBB](https://comparepv.com/panel/pvolution-pvn435-m10tcbb) | 435 W | +90 W, +4.6 pp, +5 yr warranty | | [PVolution PVN440-M10TCBB](https://comparepv.com/panel/pvolution-pvn440-m10tcbb) | 440 W | +95 W, +4.8 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +165 W, +7.3 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/pvolution-pvn345-m10tcbb Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
