PV System Simulations – Case 1
PV system simulation for latitude of 24 degrees (Bhopal) for both East-West and South facing modules, results shown below. East-West @13degrees generation will be almost 12% less in comparison with South facing@28 degree (see Fig. 1).
100 kWp area utilization comparison: East-West facing array @13degrees requires 839.02 sqm., South facing array @28degree will require 2562.38 sqm (see fig. 2). An increase of 67%.
Generation Calculation:
• Single orientation power generation + 134.3 MWh/year
• Dual orientation power generation + 154.1 MWh/year
• 134.3/154.1 = 12.8% loss
Area Calculation :
• Single orientation area calculation 41.11 x 62.33 = 2562.38 sqm.
• Dual orientation area calculation 27.25 x 30.79 = 839.02 sqm.
• Extra area required for single orientation 839.02/2562.38 = 67%
As shown in figure 3; shed loss calculations for a Single (South facing) Orientation with inter-row spacing of 4 meters, 28 degrees tilt result in losses of around 1.5%. Ideally it should not go above 1.5%. To reduce this furthermore, inter-row spacing will have to be increased to more than 4 meters.
