    What is a solar panel string?

    The “solar panel string” is the most basic and important concept in solar panel wiring. This is simply several PV modules wired in series or parallel. Solar panels feature positive and negative terminals. 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.
