Guidi Impianti was founded in 1969 in the Italian town of Pesaro and has established itself as a competent partner in the field of solar power plants. Its team is composed of expert technicians, engineers and employees, who have built more than 500 turnkey PV solar power plants.

This installation with Solar Frontier CIS thin-film modules is part of a multiple rooftop system with an overall capacity of almost one megawatt and was connected to the grid in early 2012 in Fano, Italy. Four subinstallations were comprised of Solar Frontier modules and the other two sub-installations were comprised of crystalline silicon modules. The Solar Frontier system delivers, with a total installed capacity of 734 kWp, almost three quarters of the capacity of all facilities of this area. The system of 5,063 Solar Frontier modules is expected to produce more than 900,000 kWh of electricity annually and thus offset about 500 tons of CO2 emissions.

The special challenge of this installation was the different tilt angles on the single rooftops, as they vary between zero and 30 degrees and the different orientations of the uniquely shaped rooftops. Solar Frontier modules were selected for these special conditions due to their good lowlight behavior, which generates high output even under conditions which are considered to be less than optimal, like low tilt angles or orientations other than south. These aspects as well as the local support of Solar Frontier in Italy convinced the customer and the installer.
