Solar powered water pumping system

A question from Girish Upadhyaya: I need information for a solar powered water pumping system. Say a power requirement of about 300 watts to pump 1 metre cube of water per hour to a height of about 20 metres. I would like to use a 12 v DC motor as the pumping unit drive. Can you help me with this?
