Pv On Green Roof

Research has shown that the evapo transpiration from your green roofs vegetation can have an extremely positive effect on the efficiency of pv panels.

Pv on green roof.

Certain characteristics of the plants lead to improved pv output and the modules protect the plants from high irradiance rates levels. A green roof makes the installation of a frame panels easier. This means there is no impact on the waterproofing layer below. In order to minimise any shading from the vegetation and to protect the microclimate on green roofs the pv modules are mounted higher.

When they are combined. Hard standing on traditional roofs including concrete asphalt and metal roofs all radiate heat and substantially increase the ambient temperature by as much as 30c in the case of the chicago. It is suggested that the panels optimum efficiency is at an ambient air temperature of approximately 25 c. The green roof element provides the ballast to hold the a frames and panels in place.

The pv panels should also increase the diversity of vegetation and therefore also fauna using the green roof. 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. Pv green roofs proved to be more beneficial than conventional gravel roofs for both the pv module and the temperature of the roof surface.
