One of the largest rooftop solar installations in Europe

The solar plant is located on the rooftop of the new global logistic hub of a leading global luxury group in Trecate, in Northern Italy. With 13.5 GWh, it generates more energy than it can consumes itself, which is why electricity is supplied to the grid. Over 20 million fashion items are stored on more than 162,000 m² and around 80 million items are shipped per year.

The 31,000 solar modules are securely and reliably mounted using K2's D-Dome 6 double-sided elevated mounting system. The system is quick and easy to set up, pre-assembled, with a simple click system and can be mounted without tools.

Kennew, with headquarters in Bergamo, Italy, designed and installed the solar system with K2's mounting system and Maxeon Solar Technologies solar panels. ‘The customer had specific requirements that Maxeon panels were able to meet, offering a number of advantages such as maximized performance in a given amount of roof space over a long period of time, field-proven reliability, best-of-breed durability and an industry-leading 25-year warranty on product and power,’ said Daniele Botti, managing director and co-owner of Kennew.
