Abstract

The use of green roofs helps solve important environment improvement and energy saving problems owing to their ability to reduce the effect of urban heat islands, cool surfaces due to evapotranspiration, and improve the thermal characteristics of building roof covers. The article presents the roof greening typology and methods, and considers the advantages of placing photovoltaic modules (PVM) on the green roof surface. Studies of the biosolar roof efficiency in the continental climate of Europe and Australia are presented, which demonstrate an increase in the efficiency of PVMs by an average of 4% a day due to a decrease of their surface temperature. The potential efficiency of an extensive biosolar roof under the climatic conditions of Moscow is analyzed. The PVM temperature operating conditions are mathematically modeled, and the annual energy production and capacity factor are determined at various average values by which the solar cell temperature is decreased. The expected increase in the PVM efficiency amounted to 4% per annum depending on the decrease in the solar cell temperature. The article also describes an experimental platform developed on the basis of an educational and experimental solar power plant located on the National Research University Moscow Power Engineering Institute territory to confirm the calculation results.
