Design a renewable power generation by a PV system as shown in Figure 3(b) rated at 600 kW of power at 460 V AC (three phase) using a PV module with the data given in Table 3(b). Consider input DC voltage for the three-phase inverter is 835 V, string voltage is 578.6 V, and each array power is 20 kW.

Determine the following: i) Number of modules in a string; ii) Number of strings in an array; iii) Number of arrays, and iv) Duty ratio of a boost converter.
