Can we build it with Solar Power?

So are we crazy?  Can you really use the power of the sun to build a custom campervan?  Well we are going to try to find out...  The electrical system that will be used to power our lives as we live in the van will be powered by the sun, so why not try to use that same system to power the tools needed to build the van?  For the van we have or will be purchasing 630 Watts of solar panels from NewPowa, 600 to 800 amp hours of LifePo batteries, a 3000W inverter charger from Victron along with all of our other electrical system needs from Victron.
