Determining External and System Effects on Reducing Waste Output of Photovoltaic Batteries Using PVsyst Software

The productivity of an autonomous photovoltaic plant with a capacity of 2.7 kW, installed in the parking area, was analyzed, using the PV syst program.The modeling outcomes showed, that the highest value of the global horizontal solar radiation flux density falls on the summer season and is ~ 214,0 kW•h/m 2 .Due to unused electrical energy, daily and monthly losses amount to 69,3%.Percentagewise, energy losses were distributed as follows: 6,14% due to high temperature, 2,5% due to degradation of photovoltaic batteries, 2,1% in the switching points of photovoltaic batteries, and ohmic losses in wires -1,73%.The modeling outcomes indicate the loss of electrical power, the reduction of which will lead to an efficiency improving of the autonomy photovoltaic plant.
