Green Roof With Pv Panels

Further enhancing your green roofs biodiversity.

Green roof with pv panels.

Advantages of a pv green roof compared with simple standard green roofing systems include lamnatou chemisana 2014. The panels can create shaded areas underneath with rain run off making damper areas to the front and drier areas behind. A green roof benefits from pv panels. Silicate pv panels work optimally at around 23c and american research including on city hall in chicago has shown that green roofs maintain the ambient air temperature at around 25c.

However using them together so that a building can get the benefits of both is a new idea. The combination of green roofs with photovoltaic pv panels has been proposed to provide synergistic benefits as the panel is cooled by the presence of the vegetation and thus produces more electricity while the solar panel enhances growing conditions for vegetation and increases abiotic heterogeneity resulting in higher plant diversity. In situ production of electricity by means of a renewable energy technology covering part or all of the energy needs of the building the electricity generated by the pv panels could be also used to power the water pumps used for plant irrigation. In countries such as germany and switzerland research shows that combining both solar panels and green roofs can provide many benefits livingroofs 2017.

Solar panels and green roofs are traditionally used separately to maximize the benefits from each one. In order to minimise any shading from the vegetation and to protect the microclimate on green roofs the pv modules are mounted higher. Hard standing on traditional roofs including concrete asphalt and metal roofs all radiate heat and substantially increase the ambient temperature by as. Although plant growth may be stunted due to the lack of sunlight this is offset by the water run off from the surface of the.

While as a rule the substructure is mounted in such a way that the solar panels are at a height of 10 to 20 cm green roofs require a distance of at least 35 to 50 cm from the roof.
