Problem Addressed

How to provide easily installable on-site renewable electricity whilst maintaining the traditional aesthetics of a building, encouraging the uptake of such technologies.

This solution was sourced in response to one of UKGBC’s past challenges on ‘Making Existing Buildings Net Zero Operational Carbon’.

Solution Overview modules are building integrated photovoltaic construction elements that replace conventional roofing and facade materials, with an installation that is as easy as incorporating any standard seam metal roof. modules look aesthetically like a standard non-solar roof. Electricity is produced in a thin photovoltaic layer that covers the metal sheet and the series connection of modules is made under the roof sheeting between the battens.

Environmental impact analysis undertaken by has shown a single 10kW roof will avoid emitting 300 tons of CO2, and approximately 80 million houses in Europe are suitable for installation. aims to reduce CO2 emissions by 200,749 tons annually by 2025.

Case Study

On’s first project in 2017, 60m2 (7,7kW) of solar roofing material was installed. During 2019 the house produced 7,357kWh of energy, from which 6,414kWh was used, the rest being sold to the grid. Instead of paying for the electricity used during the year, the client was paid an extra 125€ for the supplementary green electricity produced.
