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.
im always wanted to setup solar panel in mountain to reduce hiker gone missing type stuff
Yay! I hope it comes in handy.
I don't have solar yet, but I have a small portable power station that lets us avoid the manually started gas generator 90% of the time we have an outage. It's important people prepare for smaller, more common events too.
I'm getting solar panels and a battery later this month. It's mostly to keep the bills cheap and the house green, but power outages are always in the back of my mind. There's just so many ways they can happen
Using solar energy directly is also always an option, a fresnel lens or convex mirror are great for heating things. You can even make things cold using an absorption cycle cooler (the kind of things used in “propane powered” camper fridges)
