2.12 Calculate and tabulate the annual cash flows associated with a solan system for a 10 year period of analysis if the initial solar cost is $6000 and if Interest rate 9% Power cost-$30/year escalating at 10%/year Property tax -0 Income tax bracket 32% Maintenance-0.5% of the capital per year (escalating at 10%/year) Scrap value-50% of initial cost If the solar system saves $550/year in conventional fuel (escalating at 10%/year, is it cost-effective? Work the problem in current dollars. Compute the annual payment of a self-amortizing loan for the solar system with the characteristics tabulated as follows
