I want automatic shades or curtains on every window in my house (7 total) that will open at sunrise and close at sunset.

Based on my research it seems like these are the choices?

• Power supply
  • Hardwired AC
  • Hardwired Low Voltage
  • Hardwired Ethernet
  • Battery (Recharge or replace)
  • Battery + Solar panel
• Treatment
  • Curtains
  • Shades
  • Dual shades (two rollers, translucent + opaque)
  • Banded shades (one roller, alternating fabric)
• Control
  • Needs to be compatible with Home Assistant

I'd rather avoid busting open my plaster walls and hate changing batteries, so leaning towards solar powered - is there any downside? I see Lutron recommended a lot but they don't seem to offer solar panels. What brands in Canada should I be considering? Thinking SmartWings looks good so far.
