Design CalculationTotal Plant Size - 10 MW

Individual Sections- 500 kW * 20 Sets

No.of DC Cabinet - 560 V * 20 Sets

No.of AC Cabinet - 380 V * 20 Sets

No.of Inverters - 500 kVA * 20 Sets

No.of Junction Boxes - 560 W * 320 Sets

Monitoring Devices - 1 Set

Protection Devices - 1 Set

Infrastructure - As required

Each 500 kW SetPV Arrays - 16 SetsMounting Structure -16 SetsDC Junction Box (560 W) - 16 SetsDC Cabinet (560 V) - 1 SetInverter (500 kVA) - 1 SetAC Distribution Cabinet -1 Set

15 PV Arrays - Has 8 Rows

Last PV Array - Has 5 Rows

Each Row - Has 16 ModulesNet Panels (500 kW) - (8*16) + (5*16) = 2000 PanelsLike 20 Sets (10 MW) - 20*2000 = 40000 Panels
