DUONERGY Solar Panels

DUONERGY is a French photovoltaic brand from PowR Connect, headquartered in Nantes, that engineers modules for residential roofs, commercial buildings and carport projects on the French market. Its HJT line is built on N-type heterojunction half-cells laminated between two sheets of glass, giving a transparent bifacial module with a bifaciality factor above 90% — among the highest available anywhere. The DUONERGY HJT 375 (DN-BT120HJT-2) combines 120 half-cells with a -0.24%/°C voltage coefficient and a -0.26%/°C power coefficient, so it loses noticeably less output on a hot roof than a comparable PERC panel. Heterojunction cells are immune to LID and PID degradation, and DUONERGY backs the modules with a 25-year product warranty plus a 30-year performance warranty down to 88% of rated power. The panels use MC4 EVO2 connectors in an anodised aluminium frame certified to IEC 61730 for 5400 Pa snow and 2400 Pa wind loads.

DUONERGY specialises in French-engineered N-type HJT modules with transparent dual-glass bifacial construction for residential roofs, carports and agrivoltaic projects.
