Example By using the PV module which has the specifications shown in the data sheet table, Design PV system to feed a load of rare villages consist of 126 houses shown in Table E2. if the DC side is rated at 240VDC. PSH is 5.12 h, Sf is the safety factor for compensation the PV-cell temperature losses and resistive losses and equal 1.15, n and n are the efficiencies of (inverter and charge regulator) equal 0.92, 0.9 respectively. For battery choose 12V/1200Ah lead-acid battery, which has V3 and 7 are voltage and efficiency of battery block, while DOD is the depth of discharge, Cwn is the Watt hour capacity. In this regards, assuming values of 77g=0.85, DOD=0.75 and VB= 240 V.
