Green Roof With Pv Panels

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

Green roof with pv panels. It is suggested that the panels optimum efficiency is at an ambient air temperature of approximately 25 c. The green roof serves as a natural cooling mechanism thereby serving to maintain panel efficiency. The green roof element provides the ballast to hold the a frames and panels in place. A cool green roof increases efficiency research has shown that the evapo transpiration from your green roofs vegetation can have an extremely positive effect on the efficiency of pv panels.

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. 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. Green roofs not only save energy during the summer but can also increase the efficiency of pvs by reducing temperature fluctuations on the roof and by maintaining a more efficient microclimate around the pv panels.
