Regitec 420Wp Terracotta N-Type Bifacial Solar Panel RMHT48/420O2 – Wholesale 36 panels per pallet

RMHT48/420O2 is part of Regitec's O2 Series — a terracotta/orange colored glass-glass bifacial TOPCon module designed for residential and building-integrated installations where aesthetics matter as much as performance. Unlike conventional black or silver panels, the O2 Series features a warm terracotta-toned front glass that blends with traditional roof tile and facade materials, making it a strong choice for heritage-sensitive, residential, or architecturally considered projects.

The module uses 16BB (16 busbar) SMBB N-type TOPCon half-cut cells with bifaciality greater than 85%, enabling rear-side energy capture in addition to the front-side output. Anti-LID and Anti-PID technologies protect long-term performance, while RFID tracking allows quality control throughout the module's lifecycle. The module also shows excellent weak light performance in low-light conditions.

The RMHT48/420O2's efficiency of 21.02% is strong for a colored-glass bifacial module. Regitec backs it with a 30-year product warranty and a 30-year linear performance warranty guaranteeing at least 87.4% output retention — among the most generous warranty terms in the industry and matched regardless of the colored glass construction.

Distinctive terracotta aesthetic for design-conscious projects

RMHT48/420O2 stands apart from conventional solar modules with its terracotta/orange tinted front glass — a glass-glass bifacial build that maintains structural integrity while delivering a warm, tile-like appearance. It is particularly suited to traditional rooftops, Mediterranean-style architecture, and building-integrated installations where a standard black panel would conflict with the surrounding materials.

Better performance at high temperatures

Excellent temperature coefficient means more energy as temperatures rise. Every 1.8°F (1°C) rise above 77°F (25°C) will decrease your panel's output by only -0.29%.

High quality standards

Every module is backed by Regitec's certified production process, including ISO 9001:2015, ISO 14001:2015, and OHSAS 18001 management systems, with TÜV NORD, CE, IEC, UL Solutions, and RoHS certifications. 100% MES inspection ensures the reliability of every unit shipped. Regitec is a Belgian-headquartered manufacturer with production offices across Europe, the US, and Bulgaria.

Low degradation for increased longevity

In the first year of service, these panels will lose no more than 1% of their power output. The average yearly power drop from the second to the 30th year will be no more than 0.42%. After 30 years, the modules will retain at least 87.4% of their initial output.

Certified for standard wind, snow, and hail conditions

RMHT48/420O2 is certified to withstand 5400 Pa of front (static) loading and 2400 Pa of wind load, with dual 2mm glass construction providing structural rigidity on both sides without relying on a backsheet.
