Wiring solar panels in series is arguably the easiest of the three methods. In series wiring, the positive of one panel connects to the negative of the next, and so on. This creates a string of panels with a negative wire at the beginning and a positive wire at the end. However, wiring in series is not always as straightforward as it seems. In ...
A typical 100-watt solar panel is 41.8 inches long and 20.9 inches wide. It takes up 6.07 sq ft of area.
