BS Solar is useful in very limited applications..”
Bought my son a solar charger for his cell phone because they camp a lot where there is no electricity so it seemed like a good thing to have. Everytime he had a need to use it, it was either raining, snowing or very cloudy so put it in the garage sale and finally one guy offered me $.50 for it. Glad to see it gone.
Likewise. I bought a “backpacker’s solar panel” for camping/survival. Realized the hard way that even given sufficient sunlight, just getting enough direct exposure long enough is impractical. 8+ hours of full sun? ya know how many times you’ll have to move it out of the progressing shade? or how little time you’ll spend in that location? EIGHT HOURS is a LONG time to assure direct sunlight on an object. Easy enough for a large fixed facility where they can cut down all the trees and use sun-tracking repositioning equipment, but HARD for an individual on the move. Even if you do manage to, you then have to worry about someone just plain stealing it.
