The mindset shift towards “how many hours of computer usage did that one panel enable” is like the mindset shift from learning calculus, in some ways. Not quite a paradigm shift, but you gain a new appreciation for conservation of use when it’s a difference between choice of $/kW/hr and “wow, the panel powered that for most of the day”.

At the same time, many people will just use a solar calculator or watch or yard lights etc, oblivious to it all.

Show people a solar powered laptop, a solar powered phone, or a solar powered tablet, then they will be impressed.

Remember the craze about solar powered car competitions?

permacompute + solar would make for quite the $100 laptop competition.
