How Many Watts Does a 1 HP Water Pump Use?

1 HP Submersible and surface water pumps used for livestock, off-grid living, irrigation or aeration all require a baseline amount of watts to effectively run the pump all day off of solar power.

If you were to Google “HP to watts” a calculator would pop up and give you this answer. (insert photo) 1 HP equals 750 Watts. However, the pump will typically draw 20-50% or more power than just that calculation based on real life usage, efficiency and power factor. For example, the RPS Pro Deep 1 HP uses 1,200 watts of solar panels.
