Pv On Green Roof

Green roof and solar photovoltaic pv systems are two technologies that could contribute to sustainable building development and reduction of greenhouse gas emissions.

Pv on green roof.

The green roof element provides the ballast to hold the a frames and panels in place. A green roof makes the installation of a frame panels easier. The pv panels should also increase the diversity of vegetation and therefore also fauna using the green roof. When they are combined.

For every degree above this the pv panel can lose anything up to 0 5 efficiency. This means there is no impact on the waterproofing layer below. Certain characteristics of the plants lead to improved pv output and the modules protect the plants from high irradiance rates levels. 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. Research has shown that the evapo transpiration from your green roofs vegetation can have an extremely positive effect on the efficiency of pv panels. In order to minimise any shading from the vegetation and to protect the microclimate on green roofs the pv modules are mounted higher.
