Choosing Series or Parallel for Solar Panels

Solar panels can be connected in series or parallel to increase the overall voltage or current output. In a series connection, the panels are connected such that the negative terminal of one panel is connected to the positive terminal of the next panel, and the voltage is added up while the current remains the same. This requires a smaller gauge wire and can be more cost-effective, but if one panel experiences shading or reduced output, it can affect the output of the entire series. In a parallel connection, the positive and negative terminals of all panels are connected to each other. Resulting in the same voltage but an increase in the current output. This requires a larger gauge wire but is less affected by shading or reduced output on individual panels. A hybrid setup, also called a series-parallel setup, combines both series and parallel connections to achieve a balance between voltage and current output. It is important to consider the charge controller's specific requirements and limitations when deciding the type of connection to use.
