You get a portable solar panel, and charge your normal batteries from that.
They cost several hundred dollars, depending on Watts output. If you can
get a DC charger for your batteries, the kind that are sold to plug into 12V
auto cigarette lighters, then it's pretty easy. I was all set to do such a
remote thing a couple of years ago, but changed plans and ended up not
needing to. You might need to get a voltage regulator depending on the
voltage tolerance of the charger you have/get. If you can't get a DC
charger, then you need an inverter, and it gets more complicated. If I were
you, I would start by seeing whether there is a 12V DC charger available for
your video camera, say, by checking b+h. See how many Watts it draws, and
then find a solar panel with that much output. There are a lot of them out
there! Off the cuff, here are a couple of links:

Of course, you can only charge in the sun, so you'll also want several extra
batteries. You'll have to decide whether you can afford it, but it's not
heavy, and I, for one, like the technological evolution of such a

Good luck!
