What are String Inverters?

In a string inverter system, each solar panel is strung together with a specially sized "string" that carries the DC electricity to a nearby electrical box where it is safely converted into an AC flow of electricity. In comparison to other solar inverters, string inverters are much cheaper and have been around for a longer amount of time.
