Together with fifteen other leading European partners, Sirris will start an EU Joint Industry Project, in which offshore solar technology is scaled up to formats of 150 MW, enabling to build Gigawatt scale farms. These building blocks are to become a new standard in offshore energy farms. Installing solar farms within offshore wind farms will make better use of available sea space, increase energy output, provide more continuous power over the seasons and bring down costs for green electricity production and the energy system.
