I wish Texas would write up a regulation allowing 'balcony solar' as I could easily generate 1000-2000w of solar in my small back yard to take a bite out the sizeable cooling bill I have.
Seems like it's easier to ask forgiveness than permission. And, I wouldn't bet on this legislature ever doing anything that would disempower fossil energy or reduce their profits, even a little bit.
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.
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.
