TreE is an engineering company based in Gravina in Puglia, Italy and wellknown
in the area. They were among the first ones in the country to install
PV plants and last year, TreE constructed mainly rooftop applications.

This 70.20 kWp plant was installed on the roof of a farm in Gravina in Puglia,
South Italy. When the plant was installed the Italian support programme
for solar energy, the Conto Energia, was still in force. The 468 CIS modules
were chosen for their good proportion of generated kWh per installed kWp
as the majority of the produced energy is fed into the grid. Thanks to the
numerous advantageous characteristics of Solar Frontier’s CIS modules
the farmer can now access up to 10% more power than with comparable
modules. Also the executing installer is enthusiastic about Solar Frontier’s
modules and gladly recommends them to his customers.

The farmer is very satisfied with the amount of energy produced by his PV
plant: although the low tilt angle and the south-west orientation of the
installed panels are not optimal for this location, the CIS modules show
an excellent energy output and provide a yield of 1,616 kWh/kWp. In this
case, the ammonia resistance of the Solar Frontier CIS modules played a
fundamental role when it came to choosing the module type as in a part of
the farm there are living farm animals. Due to the high average temperature
in the location in the sunny south of Italy, the high temperature stability of
the CIS modules was also a crucial criterion.
