# motor-pump and PV module to reduce the life cycle cost of a system.
# It first computes the number of PV modules required for the combination
# to pump enough water in order to respect the maximum water shortage
# probability (named llp) accepted. Then it selects the combination with
# the lowest net present value.
# --------- ELEMENTS TO SIZE----------------------------------------------

# ------------- Pumps -----------
# Three pumps are available here. The user wants to find the one which fits
# best for the application. First the 3 pumps must be imported.

# Note that the motor-pumps coming from 'sunpump' follow a naming convention:
# The 3 numbers are respectively the flow rate in GPM, the Head in feet, and
# the voltage in V at the rated operating point. Note that the rated voltage
# is also the maximum input voltage for the pump.
