Interesting video, but his solar imprint was set up with 2x4s that haven't ever seen a winter. That's some young lumber he has propping up his panels, I wonder if he'll still be off the grid in winter.
Anyways what does proper maintenance cost per annum? Do you have to get someone to shovel the snow off during the winter? Or does it involve 'solar panel experts'? 'cause that's going to cost more, even if they just shovel the snow off of it in the winter.
