Am thinking the same about bringing my sewing machine--only mine is an industrial, weighs in at #300, and the motor says it is 600w (I think 1/2 horsepower). Wouldn't have a clue what kind of solar setup that would take. Planning on bringing a generator, or using it on shore power only.
I could just go with the domestic Singer, but I'm working on a business model as a traveling sewing studio that can handle heavier work, like canvas and upholstery. Not sure if this is practical, which is why I'm asking for input....
