Can anyone suggest a best size of variable speed drive for a pump?

A question from Layali:

we have 6 water wells used for irrigation, we need 4 vertical turbine pumps 300 hp and 2 vertical turbine pumps 100 hp, these pumps will tie on PV system so we need variable speed drive (VSD). I need your help to choose the best size of VSD for the above mentioned pump , are there pumps applicable to install VSD on it ? the last question if the pumps have been fed from PV system , is the pressure change or drop while the radiation was been little? please help me to understand the pressure affect by solar system ?
