MEPV NEXA is Eurener’s current N-type tunnel oxide passivated contact (TOPCon) panel family. Its wide output span covers residential-size modules and larger formats intended for commercial or ground-mounted arrays.
Four NEXA groups
The standard NEXA range includes monofacial single-glass modules and double-glass bifacial versions. NEXA Plus extends the family into larger module formats. Storm and Matte are separate double-glass bifacial sub-ranges with different front-surface treatments and module sizes.
These names do not describe one interchangeable panel. The June 2026 catalogue contains several chassis, whose current, voltage, dimensions and weight change with the full module code. A roof layout or inverter string design therefore uses the exact code rather than the family power range.
Bifacial and monofacial construction
The front-side rating is measured at standard test conditions (STC). A bifacial form can also generate from light reaching its rear surface, but that contribution depends on the mounting arrangement and reflectance below the array. It is separate from the front-side wattage printed on the module label.
Most current NEXA variants share the same published degradation curve. Its first-year allowance is followed by a linear annual allowance. That curve concerns warranted output, not a prediction that every module will degrade at exactly that rate.
Product code and warranty route
Single-glass and double-glass forms have different product-warranty periods. Eurener also advertises an extension through Premium Partners, making the supplier and issued warranty document part of the record.
Current catalogue datasheets show UK certification markings, but the family name does not identify a particular certificate entry. The complete module code must match the current certification record used for the installation.
