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.
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.
It is suggested that the panels optimum efficiency is at an ambient air temperature of approximately 25 c.
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.
The pv panels should also increase the diversity of vegetation and therefore also fauna using the green roof.
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.
The green roof serves as a natural cooling mechanism thereby serving to maintain panel efficiency.
When they are combined.
The green roof element provides the ballast to hold the a frames and panels in place.
