Call for Artists, Making Money at Juried Art Fairs, Craft Shows and Festivals
I’ve been using solar at shows for 15 yrs. I only use it for a night light display I have, so I only use a 35 ah AGM battery and a 7w panel. It also keeps my phone & iPad charged at the show.
This might not be applicable but, most shows I know of don't allow generators, no matter how quiet, for your booth.
Also many that allow onsite RV's / parking etc, don't allow generators.
You may not be looking for those puposes, though.
