I live out of my van, which gives me a first-hand appreciation for power and lighting. A few years ago, I rebuilt the interior of my van to include solar panels and a battery that powers LEDs for lighting and allows me to charge my phone and laptop.
I'm sponsored by the solar company Goal Zero, and they were gracious enough to install panels on my van and a nice battery system for the inside. I have lights and a fridge inside the van. And of course I had panels installed on my mom's house.
