NC State$$s average electrical power consumption is $30$ MW$.$ In North Carolina,

average hours of $$peak sun$$ is $5\mathrm{.}0$ hours$/$day$.$

a$.$ What is the rated capacity of solar $($in dc$,$stc terms$)$ needed to meet the annual

electricity consumption at NC State? Assume a solar derate of $0\mathrm{.}75.$

b$.$ Assuming a cost of $1\mathrm{.}1$ $$/$Wdc$,$ what is the cost per unit product of electricity from

solar PV$?$ You can assume a $10\%$ interest rate, a $20-$year equipment lifetime, and

neglect tax credits.

c$.$ If the University currently pays $$0\mathrm{.}10/$kWh for electricity from the local utility, how

much extra would the University expend on solar$-$generated electricity each year?

d$.$ If the average CO$2$ emissions rate from the local utility is $1118$ lbs$/$MWh$,$ what is

the mitigation cost in $ $/$ metric ton CO$2$ to used PV$-$generated electricity to reduce

CO$2$ emissions?
