Viridian Solar has unveiled new roofing kits that extend its existing partnership with VELUX, announced last year.

The partnership is aiming to provide a seamless combination of roof-integrated solar PV and roof windows, with the new roofing kit (F16-VBC) interfacing with the VELUX ODL Solar Integrator for a window in a position at the bottom edge of the solar array. It follows on from Viridian launching its Clearline fusion VELUX integrator (F16-VC) for this layout in March 2020, after the two companies worked together to confirm the interoperability of their systems for roof windows in a central position.

Both of the roofing kits now available are compatible with the VELUX ODL in MK08 (780 x 1398mm) window sizes.

Jamie Berryman, CSO at Viridian Solar, described the partnership as enabling “beautiful combination of solar power, daylight and fresh air from roofs”.

It follows Viridian signing a number of other partnerships, including an extension to its deal with Persimmon Homes. It has also partnered Beech Developments as well as Newland Homes and Bloor Homes among others.

Last month, the roof-integrated solar company unveiled new, larger solar modules, with the new 335Wp and 340Wp modules marking a shift away from a 156mm cell size for the firm.

Berryman added that the partnership with VELUX is “to our knowledge” the first time the company has approved the use of its solar integrator “and released joint installation instructions with a solar manufacturer for installation on the edge of an array”.

“We look forward to announcing more layout arrangements in the coming months,” he said.
