The chairmen tandem is happy to invite you to the 6th European Conference on PV-Hybrid Systems and Mini-grids in Chambéry close to the French Alps. This type of systems has been developed to fi nd solutions for the electrification of rural regions and islands and provide an enhanced electricity service. In comparison to village electrifi cation with solar home systems a central PV-Hybrid System reduces the specifi c electricity cost and enables us to provide a grid equivalent service to the users. This cost reduction is achieved by the aggregation of the expensive system components- the photovoltaic generator, the batteries, and the power converters - which are mutualised.
