Learning the basics of solar panel wiring is one of the most important tools in your repertoire of skills for safety and practical reasons, after all, residential PV installations feature voltages of up to 600V. There are three wiring types for PV modules: series, parallel, and series-parallel.
Wiring solar panels together can be done with pre-installed wires at the modules, but extending the wiring to the inverter or service panel requires selecting the right wire. For rooftop PV installations, you can use the PV wire, known in Europe as TUV PV Wire or EN 50618 solar cable standard.
Wiring solar panels in series means wiring the positive terminal of a module to the negative of the following, and so on for the whole string. This wiring type increases the output voltage, which can be measured at the available terminals. You should know that there are limitations for series solar panel wiring.
To connect solar panels in series you just plug the positive connector of a PV module into the negative connector of the next module. At the end of the string, you plug the negative connector of the first module with the positive connector of the last one to the inverter.
Solar panels do not always come with the solar connector attached. Attaching a solar panel connector to a PV wire is a two-step process: (1) crimping and (2) tightening the connector, to do this you require a wire stripper, crimping tool, and a solar panel connector assembly tool.
Although there are many different approaches to solar panel wiring, most PV installations feature: Series wiring in which each solar panel's positive terminal connects to the next module's negative terminal. Parallel wiring in which all positive terminals are connected to one another – and all negative terminals are connected to each other.
