Grid Tariff vs Solar LCOE

Crossover: Year 1 • Solar fixed R0.43/kWh

How LCOE Is Calculated

LCOE = System Cost ÷ Lifetime Usable kWh. Battery RTE penalises energy cycled through storage.

Solar LCOE
R 0.43 / kWh

Yield factor = direct use (35%) + battery use (65%) × RTE = 93.5%. Lifetime kWh accumulates each year with 0.5%/yr panel degradation over 25 years.
