To connect solar panels of the same model and rated power in series, wire the positive terminal to the negative terminal of each panel in the array. Check compatibility with the charge controller, 3. Measure the total output voltage at the end. This configuration is essential for grid-tied systems, long cable runs, and applications. . To chain multiple photovoltaic modules — like solar panels — in an array, you must connect them together and to your portable power station or other balance of system. You can do that one of two ways (or a hybrid of both). In this configuration, the voltage outputs of all panels add up while the current remains low on a level of what a single solar panel can provide. For example, a 100W solar panel can make (under standard test conditions, STC) 18 volts (V) and 5.
