Viridian Solar and Keylite are pleased to announce a new collaboration which enhances integration options for roof integrated solar panels and roof windows.
The partnership enables seamless compatibility between its Clearline fusion roof integrated solar panels and Keylite roof window sizes 06 (780x1400mm) and 07F (940x1400mm), using the VS RF flashing from Keylite.
For installations in a central position, the Clearline fusion F16-VC flashing kit combines perfectly with Keylite’s VS RF flashing, offering installers a streamlined solution for integrating solar panels and roof windows.
Founded in 2001 as part of the Keystone Group, Keylite Roof Windows has built a strong reputation for innovation in roof window solutions. Its commitment to excellence was recognised when the company named Roofing Supplier of the Year 2024 at the BMJ Industry Awards.
The F16-VC flashing kit is available through your usual Clearline fusion stockist, while the VS RF flashing can be purchased from Keylite suppliers. This solution is available for both PV16-M10 and PV16-G1 solar panels, providing flexibility across a range of roof designs.


KT Tan, Chief Technical Officer at Viridian Solar said:
“With the growing size of PV arrays, close collaboration with roof window manufacturers is essential. Our collaboration with Keylite Roof Windows underscores our commitment to delivering high-quality, seamlessly compatible solutions. We worked together to achieve a robust design, offering our customers peace of mind as the integrated system is fully tested, approved, and backed by both companies.”
Colin Wells, Head of Technical at Keylite Roof Windows said:
“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.”
