Abstract :
Methods to estimate the DC wire loss in photovoltaic (PV) systems are proposed. Root-mean-square (RMS) of the irradiance data is first related to wire losses. Then a statistical model is used to characterize the irradiance data for the PV systems. The β-distribution gives reasonable match of the RMS value for the irradiance data. The result is consistent for different geographic locations.
