MEPV Ultra is Eurener’s N-type back-contact solar-panel family. Moving the cell contacts to the rear leaves the front without visible busbars. The range includes single-glass monofacial modules and named double-glass bifacial versions.
Current forms and the UK-listed module
The June 2026 range contains several single-glass and double-glass groups. At 23 July 2026, a UK wholesaler listed one specific single-glass code.
UK availability of that code does not establish that every catalogue output is held locally. It also explains the older Ultra Premium wording that appears in some quotes and sales records. Eurener’s current manufacturer name for the family is MEPV Ultra.
Specifications change within the family
Ultra does not have one temperature or warranty specification. The lower-output groups have one published degradation curve, while the larger double-glass groups use another. Their power temperature coefficients also differ. The complete module code distinguishes panels that share the Ultra name.
The bifacial designation applies only to the named double-glass forms. Their front-side wattage is measured at standard test conditions (STC); any rear-side contribution depends on the array construction and the surfaces behind the modules.
Product and performance terms
The current catalogue gives different product-warranty periods to single-glass and double-glass bifacial forms. Eurener also advertises an extension through Premium Partners. The UK seller describes itself as one of those partners for its listed module.
Every Ultra group has the same performance-term duration, but the end percentages are not uniform. The module code and issued warranty document preserve the applicable curve and product-warranty extension.
