Light for its output, short guarantee
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.

Agrivoltaic, utility-scale and commercial.
Owners who want a long output guarantee.
Top 21% of the TOPCon 350-400 W segment, against a median of 68.9.
Bottom 19% of the TOPCon 350-400 W segment, against a median of 30 yrs.
TOPCon technology delivers lower LID/LeTID degradation and better high-temperature performance under diffuse light than older PERC cells, translating into higher real-world annual yield, particularly for ground-mount installations.
The linear power warranty extends to 30 years, beyond the standard 25 years offered by most peer comparables (Solitek, Solarwatt), reducing investment risk for long-horizon agri-PV and commercial projects.
Production from a factory listed on the Bloomberg NEF Tier-1 list, combined with German design, facilitates bank financing for large commercial and industrial projects — a key criterion for institutional investors.
45% rear-side transparency allows energy production to be combined with crop cultivation or animal grazing beneath the array, increasing land productivity compared to standard opaque ground-mount panels.
The module is engineered for snow and wind load resistance, making the series suitable for harsher terrain conditions typical of ground-mount and agri-PV installations.
Maximum efficiency of 18.7% is notably lower than peer comparables: Solitek SOLID Bifacial 19.57%, Solarwatt Panel vision GM 3.0 19.9%, and Selfa SV120M.3.2 20.3% (at the same 370 Wp power class). This means a larger mounting area is needed to reach the same system power.
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.
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.
