Monocrystalline modules: NEXA TOPCon Series

N-Type TOPCon BiF Technology up to 480Wp.

TopCon N-type bifacial cell technology is here to stay. With this new module series, we have succeeded in combining the latest developments in the photovoltaic industry in a single panel.

N-type cell

Due to their composition, these cells offer higher performance and efficiency than P-type cells, reducing the LID and LeTID effects.

TOPCon technology

It adds a thin oxide layer to the cell composition to further reduce recombination losses and increase the efficiency.


Bifaciality effectively improves rear power generation with more than a 10% increase in the output compared to having only a monofacial side.

Higher efficiency

Efficiency of more than 22% in the 430wp-435wp and 480wp output ranges.

Lower operating  temperature

Lower temperature coefficient increases energy efficiency in hot climates.

Doubles Glass

By using glass as back layer, we increase mechanical strength and resistance to rust and abrasion for increased durability.

MC4 connector

We work with the best brands of components.

Longer warranties

25 years of product warranty and performance warranty of 84,5% at the 30th year.
