In assessing the power source for a water pump needed at a distant location over a 14-year period, two options are under consideration. The pump can either be operated by a solar panel, requiring installation of solar infrastructure, or run by a diesel engine. To identify the more economical choice, perform an annual cash flow analysis (EUAC) with a 8% interest rate. Determine the optimal power source for the pump in this situation.
