What is Biosolar Roof and benefits of Installing a Biosolar Roof: Many people only think in terms of having either a green roof or solar power. The combination of these two technologies is common in other countries such as Switzerland, Germany and Austria. This combination is referred to as Biosolar roofs . Green roof and solar photovoltaic (PV) systems are two technologies that could contribute to sustainable building development and reduction of greenhouse gas emissions. Integrating them can enhance the way they work and their overall effectiveness by cooling and shading effects. The results of various experiments show a positive outcome from this integration: green roof surface and soil temperatures are reduced from the shading and higher power output of PV panels is achieved from the cooling effect.the PV system on integrated approach generated 8.3% more electricity than the stand-alone option. The degree of benefit gained will depend on the system design and whether the ...
