BioSolar – Combining Green Roofing and Solar Panels

A biosolar system combines the best elements of solar PV and green roofing and are increasingly popular with clients who need to comply with the Biodiversity Net Gain (BNG) mandate. The green roof element supports the PV's operating temperature envelope, and the PV's wind and sun shade helps improve the diversity of vegetation.

As a result, biosolar roofs can contribute to a developments’ Urban Greening Factor (UGF). However, not all biosolar systems are the same and they must be properly designed, constructed and maintained

AccuRoof, working in partnership with Eco Green Roofs (EGR), designs, supplies, installs, and maintains the SolarNature biosolar system. Eco Green Roofs has decades of experience in green roof supply and maintenance. AccuRoof is part of SIG Roofing, the UK’s largest specialist merchant of roofing related products. Together we take an integrated approach to incorporating solar PV and green roof systems into your project and provide you with system agnostic advice.
