The integration of photovoltaic (PV) panels alongside green roofs has the potential to improve panel efficiency whilst also increasing species diversity and habitats, allowing for a wider variety of vegetation to flourish.
Green roof and PV systems are two technologies that can contribute to sustainable building development and reduction of greenhouse gas emissions. When they are combined together on the building roof, it can enhance their functions and effectiveness. Green roofs can have a cooling effect and thereby help to keep ambient temperatures lower and enabling the PV panels to work more efficiently. Simultaneously, PV panels can provide different niches for organisms to live, such as creating shaded areas, while rain runoff making damper areas to the front and drier areas behind.
Utilising both technologies together also contributes to fulfilling the requirements of the Intend to Publish London Plan Policy G5 and Policy SI2.
