what specific power or capacity of water pump we need for an irrigation?

Question

We had already facts about solar water pump but it bothers us because of it's 1/2 horsepower.... thus, its capacity is enough for an irrigation...if not, then what capacity should we need?

Answer 1

Figure how much water (in gallons per hours) you can move with your pump, and figure out how much water is consumed by your crop (rainfall totals, Farmer's Almanac, whatever).

This will tell you what size of field your pump will irrigate and will let you know how close your source water has to be.
