What is interesting at this project is the modularity of the sites: the investor did not know in advance who will buy the plants, and went for a modular solution: there is 18 clusters in Italy, and 12 in Bulgaria, 1 MWp each. It is possible to group the clusters in larger plants in case that the user buys a several MWp plant. The main web server is located in the Czech Republic, providing overview of the functionality, production statistics, and alarm information. The remaining 26 MWp is designed in a standard way as more plants, several MWp each.
