The tecnological innovation
In 2011, our company took the decision to contribute towards reducing the polluting emissions by means of an important technological innovation: photovoltaic energy. The photovoltaic electricity plant installed on the roof of the Villa Guardia (CO) logistics buildings is a reference point that proves the reliability and professionalism as also the desire to continue on the path of sustainable development and the use of renewable resources. 3500 m2 of photovoltaic panels on the roof which makes G.B.D. completely self-sufficient with respect to the energy consumed in the activities, logistics and production. The production of photovoltaic based electricity provides a new imprint to the production of the smokestacks systems of G.B.D. and we proudly express of ecological commitment in the new slogan also...“CANNE FUMARIE A ZERO EMISSIONI” "0 EMISSIONS SMOKESTACKS".

Characteristics of the photovoltaic plant
The plant is made up of 628 modules in Polycrystalline silicon, and covers a surface area of 3500 m2. In order to control the performance and the optimum yield of all the modules, a remote monitoring system composed of a data logger with an Ethernet port has been connected which allows for the real time verification of the various strings of modules and obtaining the performance and alarm reports through a web page. The modules guarantee 90% of the original yield after 10 years and 80% of the original yield after 20 years. In order to maximize the quantity of energy transferred from the panels to the electricity grid, the designers, have used 12 string inverters Power-one that use the latest generation power semiconductors based advanced technology “switching” to obtain a yield with maximum efficiency equal to 97,7% of peak. The mounting system Futura Flat Roof, allows for installing the plant on the bitumen sheathing of the building without making any holes in the roofing. The aerodynamics of the structure, is enhanced by fixing flashing on the posterior edge and along the sides of each row of modules, and has been tested in a wind tunnel. The use of the flashing in the aerodynamics has resulted in the reduction of the use of concrete slabs as ballast, up to a maximum of 85% with respect to traditional systems. The south facing installation and the optimum inclination of 25° of the modules will help in avoiding the emission of 86 tons of carbon dioxide per year, as also an enormous amount of sulfur dioxide, nitrogen oxide and fine particulates.
