PCY: Per Calender Year
PCY means per capita income!
pcy
I use a conversion factor of 152 pcf (pounds per cubic foot) for asphalt, as a general rule of thumb. For a CY, multiply by 27, to get 4,104 pcy (pounds per cubic yard) of asphalt.
It falls between two unknowns:- X and Y What a question! Call your power supply company for an estimate!!! --- If you didn't know the answer why bother replying (sort of defeats the purpose of this site) General guestimate is that a medium side (30'ish) would average out at around £65 p/p pcm, around £780 pcy, but a lot of providers will do a fixed fee.
