Photovoltaic Distributed Generation Connecting to the Grid: Analysis of Solar Incident Irradiation and Electricity Generation in the Federal University of Ceara
Abstract
This article presents an analysis, in August 2017, about the characteristics of solar incident irradiation and the electricity generation from a photovoltaic (PV) distributed generation (DG), installed in the Laboratory of Alternative Energies (LEA) and connected to the grid of Pici Campus/UFC, Fortaleza/CE, Brazil. Data collection of solar irradiation and the electricity generation from the PV DG occurred through an acquisition system; the data are analyzed through the monthly average daily generation (G_mês), monthly average global irradiation (〖Ig〗_mês), average capacity factor PV (〖FC〗_med), efficiency of the PV DG (е_FV), standard monthly sample standard deviation (s_m) and the Pearson coefficient of variation (〖CVP〗_m). A 〖Ig〗_mês of 6.04 kWh/m² with 〖CVP〗_(m_ig) of 0.0810. A G_mês of 8.65 kWh, with 〖FC〗_med of 24.04% with 〖CVP〗_(m_G) of 0.0736, thus reflecting in the electricity generation the high values irradiation of the region in which the study was performed. The average е_FV was 14.71%, showing that a high irradiation does not mean that the PV DG will have a high е_FV.
