I’m only half kidding. I’m a bit of a prepper and I have lots of powerbanks and devices that charge from USB but besides idling my truck I really had no other way to charge any of them in case of a long-term power outage which seemed a bit of an oversight on my part.
Not like this solves the issue. 30 watts (under ideal conditions) isn’t much but it’s a start.
I’ve been scheming to install panels on my garage roof for a year or so. My biggest hurtle is needing to make space for an inverter next to the circuit panel, but first my hot water tank is installed too close to the panel so it can’t pass an inspection until I move it. Which means a ton of new plumbing before u even get to the new stuff. Ugggh
