CIRCUSOL is an Innovation Action project funded by the Horizon 2020 program of the European Commission.  CIRCUSOL wants to unleash the full potential of circular business models, in particular Product-Service Systems (PSS), in simultaneously delivering real environmental, economic and user benefits.  By that, CIRCUSOL aims to establish solar power as a spearhead sector in demonstrating a path driven by service-based businesses towards a circular economy in Europe.
