Sokolka – revitalization of the lagoon

Petra Energia/Solar & hybrid lamps/Sokolka – revitalization of the lagoon

A project to revitalize a lagoon in Sokolka, Podlaskie Province.
13 hybrid lanterns of the W3S3C2/50 model and 2 solar lanterns mounted on piers, characterized by a very lightweight design – only 97 kg (61 kg is the weight of the lantern, the remaining 36 kg – the weight of the battery).

The installation was entirely designed, delivered and assembled by us. The installation uses galvanized, powder-coated poles designed specifically for hybrid lanterns.
