Gotta admit I wince every time I see something new about "balcony solar."
It pains me to see people excited about investing in something that ultimately just benefits the electric utilities and still leaves you without power in an outage.
If you want a simple small solar setup, just get a 'solar generator' power station paired with solar panels. They're totally legal right now. no need for an agreement with a utility for net metering. You could immediately take your fridge and maybe more off grid. And it'll still work when the power is out. you can even take it camping with you.
@exador23 Balcony solar doesn't preclude an island setup, does it?
Agreed, directly feeding into the grid is of limited use. Still, I welcome this movement, as it indirectly puts pressure on building owners and HOAs to allow semi-permanent solar panels on balconies.
