Q: What is the difference between DC-Powered and AC-Powered solar water pumps?

A: DC-powered pumps run on direct current, which means the solar power (which is also direct current) does not need to be converted to AC-power.DC-powered pumpsare generally 20-40% more efficient than AC-powered pumps. There are also pumps which can use both DC as well as AC power as their input.
