Pv On Green Roof

The green roof element provides the ballast to hold the a frames and panels in place.

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. 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. Certain characteristics of the plants lead to improved pv output and the modules protect the plants from high irradiance rates levels. For every degree above this the pv panel can lose anything up to 0 5 efficiency.

The pv panels should also increase the diversity of vegetation and therefore also fauna using the green roof. A green roof makes the installation of a frame panels easier. When they are combined. 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.

It is suggested that the panels optimum efficiency is at an ambient air temperature of approximately 25 c. 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.
