That doesn't make any sense. Energy is fungible. Just sell your power back to the grid if it's worth more than BC. If it's worth less that BC then buy from the grid.

"Assigning" your solar cells to BC is meaningless.

Many (most?) power companies around the world don't simply buy power from solar cells at the same price they sell. Also you may very well be taxed on your income from selling electricity back to the grid, so it's not that simple.

You are taxed on your bitcoin earnings as well.
