Performance Analysis of a Rooftop Hybrid Connected Solar PV System

In the present work, a 5-kW hybrid PV solar system was installed on roof of house in Diyala, Iraq (33.77° N, 45.14° E elevation 44 m). The consists two strings, where each string nine polycrystalline modules with 355 Wp series, and strings are parallel. energy storage (ESS) parallel four 12 V 150 Ah tubular deep cycle batteries series. A inverter 5 kW rated power operated different modes. results showed that May’s monthly consumption about 822.9 1085 kWh, respectively. percentage distribution DC produced 1% losses, 27.9% used to charge ESS, 34.3% feed grid, remaining 37.64% share load. sharing load 16.67% from 33.33% system, 50% purchased. average daily reference, array, final yields were 6.07, 4.327, 3.991 h/day, array efficiencies 12.3% 92.24%, performance ratio at 65.4%.
