Eurener 440W Bifacial Solar Panel Made in Europe
Eurener Nexa ESM440-54HM10-BB module of 440 Wp, bifacial double glass with TOPCon N-Type cells and 22.56% efficiency.
Made in Europe (Bembibre, Spain), ENEA-registered for Italy's Transition 5.0, PFAS free, with 30-year product warranty and 30-year linear power warranty (88% in year 30).
The Eurener Nexa ESM440-54HM10-BB solar panel is a 440 Wp module with bifacial TOPCon N-Type cells in a double-glass (2+2 mm) structure, 22.56% efficiency and an anodised aluminium frame. It is made at the Eurener plant in Bembibre (León, Spain): a genuine Made in Europe module.
Why European manufacturing matters
For businesses the origin is not just about image: the module is ENEA-registered for Italy's Transition 5.0 plan, a requirement for the increased tax-credit rates reserved for European-made photovoltaic modules. Add the PFAS-free certification and a supply chain with documented traceability (SEIA pledge against forced labour) and you get a product that stands up to tender and incentive compliance checks.

How much does an ESM440 array produce?
Just 14 modules pass 6 kWp over about 27.5 m2. On a south-facing roof in central Italy that is roughly 8,500-9,200 kWh per year: the typical size for a house with a heat pump, storage and an EV to charge. The -0.29 %/°C temperature coefficient and the N-Type cells limit the summer drop compared with a PERC module of the same power.
Frequently asked questions
Is the module eligible for the Transition 5.0 tax credit?
The ESM440-54HM10-BB is ENEA-registered in the list of European-made photovoltaic modules under the Transition 5.0 rules. Entitlement to the incentive then depends on the whole project and its energy-saving requirements: the module meets the origin requirement, but the application must still be certified by a qualified professional.
What does PFAS free mean on a photovoltaic panel?
It means the module is built without per- and polyfluoroalkyl substances, typically present in some backsheets and encapsulants. In the double-glass version there is no backsheet at all, and Eurener certifies the absence of PFAS across the whole product: an advantage in view of REACH restrictions and end-of-life disposal.
What does the BB suffix in ESM440-54HM10-BB indicate?
It identifies the module's finish within the Nexa Double Glass Bifacial series: the anodised aluminium frame is available in a black or silver version. The electrical characteristics remain those of the 440 Wp class shown in the table, regardless of the finish.
Is the 30-year product warranty real?
Yes: the Nexa double-glass series is covered by a 30-year product warranty and a 30-year linear power warranty, with guaranteed residual power of 88% in year 30. That lifespan is made possible by the glass-glass structure, which removes the backsheet, the main weak point in the ageing of traditional modules.
Does the 24 kg double glass need a reinforced structure?
Generally not for a standard roof: 24 kg over 1.96 m2 is about 12.2 kg/m2, in line with a traditional module of the same format. The fixing points indicated in the Eurener manual must be respected and the snow and wind loads of the area checked, taking into account the stated limits of 5400 Pa front and 2400 Pa rear.
