The storage tank Olivella is located in the municipality of Sant'Elia Fiumerapido (FR). It has a length of 123 m and width of 72 m, for a total area of 8656 sqm
The project envisaged the installation of a fixed floating photovoltaic system on the bath surface, integrated with the structures.
The energy produced is used for self-consumption for the operation of the lifting plant and the excess is fed into the net.
The photovoltaic power station consists of 1432 modules (total capturing surface: 2329.68 mq), organized in 5 floating islands connected by removable stainless steel walkways with access and spacer function. Each island consists of multiples of floating units consisting of 4 photovoltaic panels and 8 floating each of 1.02 Kwp.
The passage of the cables to the floating island is ensured by a channeled system fixed to the metal structure.
