3. SPV GRID TIE – Without Battery

4. Design Calculation
Total 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

5. Each 500 kW Set
PV Arrays - 16 Sets
Mounting Structure - 16 Sets
DC Junction Box (560 W) - 16 Sets
DC Cabinet (560 V) - 1 Set
Inverter (500 kVA) - 1 Set
AC Distribution Cabinet - 1 Set
15 PV Arrays - Has 8 Rows
Last PV Array - Has 5 Rows
Each Row - Has 16 Modules
Net Panels (500 kW) - (8*16) + (5*16) = 2000 Panels
Like 20 Sets (10 MW) - 20*2000 = 40000 Panels
PV Array – 16

6. 250 Wp Si-Mono Panel
