Balcony solar panels can save 30% on a typical household’s electricity bill and, with vertical surface area in cities larger than roof space, the appeal is clear
They have an inverter that increases the voltage to 230V and then you can plug it into a regular outlet. The cables don’t care in which direction the electricity flows. It only becomes an issue at the power meter, but newer ones prevent backflow and usually these small PV systems don’t produce enough to not be consumed by always on stuff like refrigerators anyways.
