Laterza 1-2, 2MWp c-Si PV system, Puglia, Italy

PV field design, engineering and construction services.

  • Total installed power capacity: 2MWp (1981.5 kWp)
  • Comprising of: 9174 c-Si PV modules
  • PV modules: Yuraku A-P. 216, multicrystalline, 216Wp
  • Inverters: Power One, nr. 36 units, each 55kVA
  • MV transformers: 2 transformers take system voltage to 20,000 V for connection to Enel's MV line
  • Hot zinc coated metal structures are designed for a virtually maintenance-free life of 30-years
  • PV field layout: 417 strings of 22 PV modules each connected in series
  • Each string is connected to the inverters through parallel junction boxes with Hall sensors, switching capability to selectively maintain strings in the PV field
  • Care has been taken to accurately size cables and all wiring to minimise losses and optimise performance over a 20 year expected lifetime
  • PV modules have been selected for each string so as to maximise efficiency
  • Total system losses are expected to amount to some 10%
  • Annual energy production is expected to be: 2,622,000 kWh
  • A total solution surveillance system allows our client to monitor in real time the performance of the PV field to maximise security and reduce maintenance to on-demand basis, substantially reducing costs
