Benefits of Biosolar Green Roofs
Besides the obvious benefits of freely generated electricity, the solar and green roof combination adds a number of additional eco opportunities.
Solar PV panels create shading on the roof surface where new habitats are created allowing a large range of species to thrive on what would otherwise be a very exposed area on the roof.
Rain run-off from the panels creates damper areas to the front and drier areas at the back. This creates a ‘habitat mosaic’ which allows a wider variety of vegetation to flourish and, in turn, attract a wider range of species such as butterflies, bees, beetles and others.
Green roof substrate can ballast or provide an anchor for the solar base, eliminating penetrations of the roof membrane through waterproofing.
Biosolar roofs provide an opportunity to exploit unused roof space to generate free electricity, increase the lifetime of the roof, and with thoughtful planting, provide a vital habitat for urban flora and fauna essential for future healthy population centres.
