Formulas used:
Total generation = Capacity (kWp) × Estimated generation (kWh/kW)
Savings/unit = Unit cost (grid) − [Solar PPA + Grid support charges]
Overall savings = Total generation × Savings/unit

Formulas used:
Total generation = Estimated generation (kWh/kW) × Capacity (kWp)
Net generation = Total generation × [1 − (Wheeling loss + Transmission loss + Other loss) / 100]
Savings/unit = Unit cost (grid) − [Solar PPA + Wheeling charge + Transmission charge + Other charge]
Overall savings = Savings/unit × Net generation
