UK-based manufacturer of roof integrated solar panels, Viridian Solar and Keylite have announced a collaboration that enabled compatibility between Clearline fusion roof-integrated solar panels and Keylite roof window sizes 06 and 07F using the VS RF flashing. The Clearline fusion F16-VC flashing kit matched with Keylite’s VS RF flashing for central installations and supported PV16-M10 and PV16-G1 panels. Keylite, founded in 2001 under the Keystone Group, was recognised as Roofing Supplier of the Year 2024. Both companies said the joint design was tested, approved, and intended to offer a coordinated setup for integrated panels and roof windows.
