Inside Power Roll’s Flexible Solar Film

19 November 2025

In this episode of the Raw Green podcast, Neil Spann, CEO of Power Roll, joins co-hosts Francesco De Lieto and Emma Mee to discuss how they are reinventing solar architecture to power the millions of buildings that cannot support the weight of traditional solar panels.

They explore the engineering behind their microgroove technology, which allows solar cells to be printed on flexible plastic film using high-speed roll-to-roll manufacturing. This process creates a lightweight, bendable solar film that functions where heavy, rigid glass panels fail, such as non-load-bearing rooftops or curved surfaces.
