See, there's a bunch of different ways you can Do Solar, depending on how Into It you wanna get. I'm typically on the raccoon end of the spectrum y'know, scavenge parts and cobble together and try to do it all on the cheap, which would normally rule out the sort of all-in-one inverter/chargecontroller/battery devices that rich folk go for. These are devices where you literally just plug solar panels in, keep your voltage below the max, and it does it all for you with an app, you don't have to know anything.

But. Big part of my use case was, frankly, next time there's a massive storm and half my mates are without power for days at a time and they need their freezer to get cold and their phone to get hot, I wanna be able to chuck a thing in the car, wheel it over, give them a couple cycles and take it back to get charged up in the sun again, and that ain't happening with the sort of screwed-into-a-big-plywood-board system I'd initially been thinking about. Plus I'd saved some money on the actual panels by finding a bloke who's upgrading all his, so the panels I'm getting are gonna be big and old and heavy and blue and not very efficient for their size but very very very cheap.

So. Gulp.
