Tom's Hardware normally focuses on computer performance. They opted
out of using a notebook which are designed from the top down to be
more
energy efficient because it was less of a challenge and they wanted
to make something with more computing power. This is the first time
I can recall them addressing computing energy efficiency.

My gut reaction was that the full electrical load
of 115w is a tad excessive but Tom's Hardware Group
wants a very fast workstation and they're willing to
build a bigger solar array system to accomodate it.

Yet ISTM if I'm out in the middle of nowhere with
a computer running on batteries and a few
solar panels - I would be thinking more than twice
about wasting any of precious battery power
on anything more than the basics like
internet, email, word processing, and a
power grid monitor. I'm expecting that the cost
the electrical storage system is about half the
cost of a solar panel system.
