Solar Electric and/or Solar Water

[EightFingers]

Not true. 220v. motors are not more "effcient" than 110v. motors. The "benefit" of 220 is it takes fewer "amps" to do the same work. You're still using the same amount of "energy" or "wattage". The higher the voltage, the smaller the conductors required for the same energy output. That's the main reason volatges are "stepped up" --> distributed --> and "stepped down" at your house. You'll never see 110v. distribution lines. 220 v. motors ARE more effcient in that they are less expensive to produce.

Side note: I got a kick out of reading a real estate listing touting the garage/shop had 220 amp service.
