There are good reasons you aren't allowed to plug random power generators into the grid. You might be allowed to have your own ones not connected to the grid. Remember that graphics cards run off poorly regulated 12V, although you'd want to regulate it anyway because they're expensive to replace if I'm wrong.

Nobody mentioned plugging into the grid.

		Balcony solar by definition plugs into the grid. It's not just "solar panels that happen to be on a balcony", it's a certain type of self-contained unit that plugs into a regular power outlet.
