nversion efficiency of $20\%.$

onsider a PV system that have $20\%$ Energy Conversion Efficiency and a cost of $$50m^2$ tallation cost is $\frac{50}{m^2}$; thus a total cost initial cost of $\frac{100}{m^2}.$ Assume $5\%$ of the total cost ini be the yearly maintenance cost. Assume the solar system power output will degrade by $1r,$ till year $25$ where PV systems will be discarded as its performance & degradation will redictable; thus, assume the lifetime to be $25$ years.

mate the cost of the electricity produced $(KW\frac{h}{S})$ by a PV system over its lifetime, the elized Energy Cost of Electricity$).$ You will need to compare the cost of the electricity ro interest rate and your choice of an interest rate that capture the risk, opportunity cos value of money. Note: Account for time$-$value of money using the model we discusse and chose a reasonable interest rate $($i$)$ and justify that value for the interest rate.
