You need to produce $20$ kW of electric power constantly using either a $50\%$ efficient natural gas generator costing $$500/$kW using fuel costing $$3/$GJ $($$$0\mathrm{.}01/$kWh$)$ at a CF$=100\%,$ or using solar panels costing $$1500/$kW with a $25\%$ capacity factor and an energy storage subsystem. You can get financing terms for either system with TDF $=10$ years. What is the levelized cost of electricity production with the generator system $($$$/$kWh$)?$
