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.
A green roof makes the installation of a frame panels easier.
This means there is no impact on the waterproofing layer below.
It is suggested that the panels optimum efficiency is at an ambient air temperature of approximately 25 c.
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 green roof serves as a natural cooling mechanism thereby serving to maintain panel efficiency.
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 pv panels should also increase the diversity of vegetation and therefore also fauna using the green roof.
When they are combined.
