Voltage Behavior: The voltages of each panel add together. For example, if three solar panels rated at 40V and 10A are connected in series, the system will produce 120V and 10A. It is important to understand these two configurations as we have to estimate our home needs or power storage for. . Solar panels wired in series increase the voltage, but the amperage remains the same. The reason why series connections are utilized with MPPT controllers is that MPPT Controllers actually are able to accept a higher voltage input, and still be able to charge your 12V or more batteries.
