When I repowered a couple of years ago I was quite excited about going electric. I researched it quite extensively but as much as I wanted it to work, I just couldn't make it stack up.
The quantity of battery storage and solar panels needed for typical use just doesn't work. Weight, space, expense, range and windage were all major issues.
Without getting into the politics of the global warming nonsense, it doesn't stack up environmetally either.
