I'm sure it won't be as efficient as a large operation, but neither can I get my surplus power to an industrial operation. And I'd happily follow the power supplies - run equipment during the day, when it's clear, not run it at night, etc. I'm already used to using energy based on what's available, this would just be something additional to add into the blend.
I've got an awful lot of basalt laying around, though...
It will just never be as efficient as an industrial scale operation.
