Integrating green roofs and solar photovoltaic (PV) systems can enhance the way they work and their overall effectiveness by cooling and shading effects. The results from numerous experiments display a positive outcome from their integration; green roof surface and soil temperature are reduced from shading and higher output of PV panels is achieved from the cooling effect. If the micro-climate around panels is too hot the panels may not work efficiently. Green roofs help to keep ambient temperatures around the panels close to 25c, the ideal temperature for solar energy production.
Green Roofs and Solar Power should be Part of our Future
Many experts believe that biosolar (green roofs and solar panels) technology could deliver widespread environmental, social and economic benefits. Vegetation lowers the heat load on a building’s roof and reduces air-conditioning needs and costs; cutting down on residents’ electricity bills and reducing their carbon footprint.
With the fight for space becoming an ever-worsening issue in cities, roofs provide an oasis of unused space that can be exploited to meet the energy needs of residents and support a vital habitat for wildlife.
