Solar Fabrik has developed a red-brown solar module designed for use on historic buildings and in heritage-protected areas where strict aesthetic requirements apply.

The “Mono S4 Halfcut Chroma Orange” module is a colored panel intended to blend with traditional red-tiled roofs. The company cites an efficiency of 20.02% and a power output of 400 W.

It is a bifacial monocrystalline n-type glass-glass module with 96 tunnel oxide passivated contact (TOPCon) half-cells, measuring 1,762 mm × 1,134 mm × 30 mm and weighing around 24 kg.

The front glass is a 2 mm copper-red pane similar to RAL 8004 and features an anti-reflective coating, while the aluminum frame is also color-matched to a similar tone (RAL 8011).

The module is rated for a maximum system voltage of 1,500 V and operates in temperatures ranging from −40 C to 85 C, with a power temperature coefficient of −0.29% per degree Celsius.

In terms of durability, the module is designed to withstand hail impacts from ice balls up to 40 mm in diameter at speeds of up to 29.2 m/s, and snow loads of up to 5,400 Pa.

Solar Fabrik offers a 30-year product and performance warranty. Shipments to distributors are scheduled to begin in April 2026, while pricing has not been disclosed.
