Re: 220 Well pump...how many panels, batts?
This is really not a good idea. The cost for enough solar power to achieve this (approximately 6 kW hours per day, not including surge requirements) is astronomical. You would be better off staying with utility power and adding a grid-tie system to off-set costs (if there's enough incentives in your area).
Water is very difficult to pump. It's heavy. Even lifting 76 feet requires a lot of power. If there's no utility available (as in you want to get away from a remote generator set-up) you should look in to alternative pumps http://store.solar-electric.com/sodcwapu.html rather than try to build a battery-based solar electric system to supply the existing pump.
Sorry this is not a 'happy' answer.
Four 175 Watt panels, OB MX60, 232 Amp hrs, OB 3524, Honda eu2000.
Ohm's Law: Amps = Volts / Ohms
Power Formula: Watts = Volts * Amps
