A balcony solar power system (also called a plug-in solar panel, mini solar system, or balcony power station) is a small photovoltaic system designed to generate electricity for direct use in a home or apartment. Unlike conventional rooftop solar installations, balcony solar systems connect to the existing electrical circuit of a building through a standard power outlet or dedicated socket, without requiring significant structural modifications or professional installation in most configurations.
The funny thing about the feed cutting out when the mains are out is that if there’s a power grid failure because too many solar panels are feeding the grid, you end up without power. It’s happened to us a bunch of times.
