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.
That’s a massive panel for so little wattage.
Look up 25% next time, they maximize the area! N-type’s are also great for enduring high temps and weathering high uv.
Is 25% the brand name?
Refers to the efficiency. 25% needs less area to generate the same amount of power. The efficiency has been steadily rising from 18% now to 25%.
Yeah it’s a lot of panel for 30W.
