That solar panel looks useful.
Since I have never gone out in nondescript black clothing at night to destroy these things, I can’t say from firsthand knowledge…
But yes, yes they are. They make great trickle chargers for large batteries that only get used intermittently. Or string several together and enjoy an ebike battery charger. I have a similarly sized and shaped panel I found somewhere that I use to charge my 18650 bank.

People who believe in “auras” and actually think that thinking good thoughts in relation to a specific thing will affect it on any way are deserving of mockery.
It’s religion for people who don’t like organized religion.
