The Lower Austrian Photovoltaic-League highlights the most successful communities in terms of increasing their installed PV capacity. The competition takes place once a year and even small communities have the chance to capture the trophy.In order to balance the chances between small and large communities, the target figure is defined by the yearly gains in installed PV capacity per capita. The champions of each district have the possibility to take part in an award ceremony where they receive their trophies. The most successful district champion will be declared state champion.The requirement for a comprehensive data set is the cooperation with power utilities that report the installed PV capacity in their power grids once a year. The communities have the chance to benefit from dissemination activities like regional press releases and online activities. In 2017 the Lower Austrian Photovoltaics-League was carried out for the sixth time.
