Just found this video and I think that it’s really neat. This guy has a solar powered portable ice maker setup. Imagine getting free ice powered by the sun!
He’s got about 6 panels setup, outputting around 90 watts for his ice machine. The panels are connected to a charge controller which is in turn connected to some deep cycle batteries.
I think this is really smart. When do you want ice the most? When the sun is shining! What a great way to cool down when the sun is hot.
