What is a Solar Panel String?
An electric circuit is created by wiring together the solar panels. Current flows through this circuit and once they are wired to the inverter the conversion of DC to AC begins. This power is then consumed by your household appliances. The wiring of solar panels with each other and then to the inverter is referred to as stringing.
