Hard standing on traditional roofs including concrete asphalt and metal roofs all radiate heat and substantially increase the ambient temperature by as. While as a rule the substructure is mounted in such a way that the solar panels are at a height of 10 to 20 cm green roofs require a distance of at. Over the last few years research shows that green roof can provide a boost to the amount of solar energy gained on a green roof. Green roofs increase the efficiency of pv panels.

Using solar technology with green roofs is an increasingly important element in delivering sustainable solutions on buildings and in cities. In summer the lush growing and diverse blanket of green roof plants are like small air conditioners for the heat sensitive pv elements. Solar garden roof 1 in the united states fully integrated no penetration. The green roof helps cool the surrounding air providing a cooler temperature that allows the solar panels to perform more effectively environmental protection agency 2017.

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. Advantages of a pv green roof compared with simple standard green roofing systems include lamnatou chemisana 2014. In situ production of electricity by means of a renewable energy technology covering part or all of the energy needs of the building the electricity generated by the pv panels could be also used to power the water pumps used for plant irrigation.

At the same time these plants will retain more than 50 90 of the annual rainfall preventing it from running off into our already stressed sewer systems and waterways. The green roof and pv are a highly practical combination. Bauder biosolar is an integrated mounting solution for photovoltaic renewable energy with a green roof where the substrate and vegetation provide the ballasted installation mechanism which removes the need for penetrating the waterproofing to secure the mounting units to the roof. A flat roof is one of the best locations for a solar energy system given that the solar modules can be adjusted to the correct angle and the most appropriate orientation.

In order to minimise any shading from the vegetation and to protect the microclimate on green roofs the pv modules are mounted higher. The company green roof technology has created their own system for installing solar panels and a green roof together and has done extensive research on the benefits. The solar green roof market. Green roofs and solar energy biosolar roofs provide pure synergy.
