Balcony solar panels can provide enough power for residents to run, free of charge, home appliances such as fridges, dishwashers, washing machines and wi-fi without spending money on electricity from the grid. The panels are smaller than standard rooftop panels and can be zip-tied in place without professional installation.
They are blocked, not by Trump, but by state laws in 49 states and DC, laws that typically require anyone who installs solar panels to strike an agreement with the local utility for the power they are feeding back to the grid. The installation of panels also typically has to be done by contractors and be inspected.
Utah simply carved out an exemption from interconnection agreements for people generating 1.2 kilowatt of power or less.
