Performance Analysis of 15kW Solar PV System

Abstract

In recent years, Iraq has suffered from a severe shortage of electricity supply to the government and domestic sectors, whose production depends on fossil fuels, which requires the investment of another energy source to make up for this shortage. The sun is one of the giant energy sources friendly to the environment and renewable and Iraq is one of the rich countries of this kind of energy source. In the present work a 15 kW of PV solar system type HIP-205BA19 was installed Baghdad's Training and Energy Research Center, which is part of the Iraqi Ministry of Electricity. The performance of a Grid-Tied plant with a capacity of 15kW in the Baghdad environment was evaluated. The solar systems were synced with a 0.4kV low voltage distribution sector and their annual performance was monitored. During the time period studied, yearly energy production was 23669.22 kWh. The daily average of array, final, and reference yields were 3.15kWh/kWp, 3.03kWh/kWp and 3.86kWh/kWp, respectively. The result, also, indicated that the yearly daily-average of overall, array and system losses were 1.62kWh/kWp/day, 1.45kWh/kWp and 0.17kWh/kWp, respectively, Inverter, system, and array efficiencies were 96.2 percent, 13.16 percent, and 13.68 percent, respectively, on an annual basis. The capacity factor and performance ratio for were 18.01 percent and 72.5 percent, respectively, on an annual basis. These findings revealed that the systems performed admirably under Baghdad's climatic conditions.
