You really do not want know.

Your question cannot be answered accurately because you have not provided enough info like where you live and will it be year round operation.

But for an example in Kansas City operation you will need you would need:

Batteries = 11,600 pounds, cost about $28,000 and need replaced about every 5 years.
Solar panel wattage = 20,000 watts and cost $60,000

Do you really want to know more? If so open your own thread.

Yikes.

I've moved the thread, so you have 1.6Kw of pumps to run for 10 hours a day. And if most areas only get about 4-5 hours of sun, you have 6 hours to run off batteries.

The killer is you have to run the pumps AND recharge a large battery bank at the same time.

If you can shift to solar only, and you pumped twice as much for only 4 or 5 hours, you could GREATLY reduce the system size.

What are the pumps for ? cattle water ? irrigation ? Can you pump less if it's cloudy and plants don't need as much water ?

Give us more info as to what the actual job is, and we can come up with a scheme that should work for less than Sunkings strict estimate.
