Biosolar roofs contribute to a comfortable urban microclimate and increase the yield of photovoltaic panels. The main goal of the project is to develop pre-grown biodiverse carpets for biosolar roofs suitable for locations with different climatic conditions in cooperation with GREEN DEPOT. Another goal will be a proposal to increase the plant species diversity on existing roofs, tested on a real biosolar roof in Zdar nad Sazavou. The dissemination of information will be done through a Handbook for users of biosolar roofs, which will also serve as a communication tool between the company and the customer. The final products will be marketed by the partner, thus fulfilling the national RIS3 strategy: direct use of the research results for the company's needs, reflecting the needs of society.
