Solar Panels in Series Wiring Diagram

Wiring solar panels in series means connecting multiple panels together in a single circuit, with the positive terminal of one panel connected to the negative terminal of the next panel. This configuration increases the overall voltage of the circuit, but does not increase the current. Wiring solar panels in series is useful when the panels are being used to power a system that requires a higher voltage, such as a grid-tie inverter. However, it's important to note that if one panel in a series circuit is shaded or otherwise not producing electricity, it can reduce the output of the entire circuit.

The shading issue can be reduced drastically by the use of modern solar panels with built-in separation diodes between the solar cells such as the Victron 175w Bluesolar Panels
