This is the real experience in a PV plant in Piacenza (Northern Italy) where the wide range of input voltage of the Omron Inverter maximize productivity hours in the year
The best solution to repair at the uncertainty of the incentives scheme experienced recently in Italy is to increase solar productivity hours during the year: this is the experience of Tredi Elettronica, the owner of one 1MWp plant near Piacenza where energy output reached 1740 hours in one year, a high number compared with productivity of other plants nearby, with an average of about 1000 hours per year.
That is a photovoltaic plant using solar tracking systems, on a five hectares field, with 98 biaxial solar trackers, each one with an array of 72 square metres and at a distance of 20 metres the one from the other.
The plant, connected to the grid in 2010, has been designed with an Inverter for each tracking pole, to have the control on any single part of the plant and to be able to find the exact point of failure.
The plant has 98 Inverters: 48 of them are KP100L from Omron, with efficiency peak 97,5%. The other 50 inverters are from another supplier, with a higher peak efficiency (98%), confirmed by real measurements on field. At that time Omron did not have enough pieces on stock to satisfy the whole request.
