• A van is certainly going to be cheaper to put solar on than a whole house LOL! That’s completely understandable. Yep, I’m sorry, I usually assume people are talking about homes because I don’t have a van, and so I misjudged youe capial involved as a lot more than I’d have. For van living I’d say it’s a must-have regardless of price, considering that you might not have grid hookups consistently!
