How To Wire 3 Solar Panels Together
To solve this problem and to optimize the energy performance of the entire system it is advisable to wire two panels in series obtaining a doubling of the voltage and then wire in parallel the three pairs previously wired in series so as to have doubled the voltage and tripled the current.
How to wire 3 solar panels together. When solar panels are wired in parallel the positive terminal from one panel is connected to the positive terminal of another panel and the negative terminals of the two panels are connected together. The positive wires are connected to a positive connector within a combiner box and the negative wires are connected to the negative connector. The white line is the negative connection all 3 panel negative wires are just simply tied together and to the wire that runs back to the negative connection on the charge controller. Solar panel wiring aka stringing and how to string solar panels together is a fundamental topic for any solar installer.
Looking at the picture it is possible to understand the scheme of this connection.
