Solar Design Help


Recommended Posts

Hi everyone.  I need solar power for a well pump to irrigate.  I have 14 panels rated at 240 Watt, 30VDC,7.9ADC....I need to power two(2) - 1.5HP well pumps for a total of 3 HP to run.  I have ordered two inverters from china and both of them blew up.  They would not replace them so I am needing someone to help me figure out what I need to use with the panels in order to run the pumps.  I really needing help with the calculations of what I need.  I'm new at this solar stuff and there is really no one around where I live that is knowledgeable.  Do I have enough solar panels?  What size inverter(s) do I need?  The pumps should only run 4-5 hrs/day.  Any help would be appreciated.
