Keylite launches Viridian Solar collaboration

 25 Nov 2025

Keylite Roof Windows (Keylite), part of the Keystone Group, has launched a collaboration with Viridian Solar (Viridian) to enhance compatibility between roof-integrated solar panels and roof windows.

Viridian Solar, a UK-based manufacturer established in 2004, is renowned for advancing the building integration of solar technology and for producing high-quality roof-integrated solar systems.

The partnership enables seamless compatibility between Viridian’s Clearline Fusion roof-integrated solar panels and Keylite roof windows in sizes 06 and 07F, using the VS RF flashing.

For central installations, the Clearline Fusion F16-VC flashing kit aligns perfectly with Keylite’s V2 RF flashing, providing installers with a streamlined, integrated solution for combining solar panels and roof windows.

KT Tan, Chief Technical Officer at Viridian Solar, commented: “With the growing size of PV arrays, close collaboration with roof window manufacturers is essential. Our collaboration with Keylite Roof Windows is key to delivering high-quality, seamlessly compatible solutions.”

Colin Wells, Head of Technical at Keylite Roof Windows, added: “Partnering with Viridian Solar allows us to deliver a fully integrated solution that combines our roof windows with their Clearline Fusion solar panels. This collaboration reflects our ongoing commitment to innovation and provides our customers with a streamlined, compatible system for creating smarter, more sustainable rooftops.”

Renowned for its award-winning innovation, Keylite provides a comprehensive range of roof windows, blinds, timber loft ladders, flashings, electric operations kits and accessories.
