Solar panels are so cheap and so good now that it is becoming embarrassing if you don't have any.
You’re really going to need to UL list these things or something. Otherwise Murdoch and the NY Post will be running stories like, “balcony catches fire from liberal solar panels!” Ignoring that the tenant probably ordered the panel from Amazon or Temu or bought it from the back of someone’s van.
Tons of panels themselves are UL listed, including the ones on Amazon. I assume the same for Temu, but have no inclination to check.
Generally these "solar balcony" kits are all in one setups with a power regulator and sometimes a battery built in. The power regulator makes sure no power flows back into the grid when the grid is down, for safety. These are not UL listed just yet, although some companies are working on it.
Everything about energy production and storage.
