Problem $3$

A $100$kWdc PV system is being proposed for a commercial building in an area with $5\mathrm{.}5$ kWh$/$m$2/$d insolation. The before tax$$credit cost of the system is $$5/$Wdc$.$ Assuming a $0\mathrm{.}72$ derate factor, a $30\%$ renewables investment tax credit, $$5/$kWdc$/$year annual O&M$,$ and a fixed charge rate of $15\%/$year:

a$)$ What is the annual electricity production that might be expected? b$)$ What is the levelized cost of energy?
