2012: Supplying for ourselves

Cartografica Pusterla - Vista aerea

In the course of the year 2010 we started facing the issue of decreasing our dependency on the supply of electric energy from external sources, albeit renewable, thanks to an independent energy production that could exploit the southern exposure of the buildings in which we operate.
For this reason, we chose to install a system that uses the sun as a renewable source of energy.

The ideal surface for placing the solar panels was identified in a part of the roofing did not host skylights and cooling and/or air extraction systems.
Initially, the parabolic shape of the roofing tiles was an obstacle, since it does not allow the panels to be uniformly hit by the rays of the sun.
After in-depth research we found the solution to our problem in CIS technology panels, the Powermax SGS modules produced by Saint Gobain.
This technology exploits a wider light spectrum and is highly performing on East-West exposures, which is the lateral inclination of the slopes of our roofs.
In order not to weigh down the building with a strong overload, due to the fact that the wind’s action on the panels needed to be contrasted, we chose to place the panels parallel to the roofing surface and to fix them with a system based on the VELCRO principle that guarantees high resistance, easy fixing and weight reduced to only a few hg. per square meter.

Moreover, this type of placement does not interfere in the least with the architectural design of the buildings, since it is not visible from outside.
The photograph you see is in fact an air view.
The theoretical power generated by the panels is equal to 159 Kw, which on an annual basis corresponds to 12% of our yearly consumption.
The system started working in February 2012, and up to today we can confirm the validity of the project both in terms of energy savings, especially in the summer months when cooling is required, and in terms of the satisfaction it gives us to produce energy without emitting polluting substances.
