45. For customers generating their own solar power, ZG&amp;E charges them $3 per month per kilowatt (kWh) for excess electricity
uranmaximum [27]

(A) The customer that owns a 3-kW system exports 120 kWh monthly to the grid will have the following bills for both companies:

For ZG&E that collects $3 per kWh on a monthly basis, the monthly bill will be

120kWh\times\frac{\$3}{1kWh}=\$360

For Ready Edison that collects $0.06 per kWh exported energy monthly, the computation of bill will be

\$20+(120kWh\times\frac{\$0.06}{1kWh})=\$27.2

(B) The customer that owns a 5-kW system exports 300 kWh monthly to the grid will have the following bills for both companies:

For ZG&E that collects $3 per kWh on a monthly basis, the monthly bill will be

300kWh\times\frac{\$3}{1kWh}=\$900

For Ready Edison that collects $0.06 per kWh exported energy monthly, the computation of bill will be

\$20+(300kWh\times\frac{\$0.06}{1kWh})=\$38
