that should be no problem. i have heard of solar well pumping up to 1000 feet if you get the right pump. check out dankoff in new mexico or wholesalesolar.com

Actually with solar direct pumping you can pull water from up to 750 feet at low flow rates.  This is not pressurized water.  It basically pumps when the sun is out into a cistern.  Don't forget to figure in the depth of the water in the well PLUS the amount of elevation that you need to push the water up the hill above the well location.  This is called "Total Dynamic Head" or TDH.  In this type of system more solar panels are need at deeper depths.  At shallower depths more solar panels deliver higher gallons per min.
