[J. T. Toad]

This "maintenance problem" is like, to use the prior analogy, showing up to race @ LeMans with square tires, a Briggs and Straton power plant, and forgetting fuel.

I hate to say, but the application of present day technologies to prove an "everybody should be doing this" mentality is juvenile.

The energy storage (battery) wouldn't have been able to realistically sustain the house from the get go. Let alone the implied environmental concerns for the ENTIRE experiment.

I would hate to be on the space station, submarine, airplane, to find out failure would be written off as a "maintenance" issue.
