There are so-called parallel connections and series connections. If the voltage of a solar panel is sufficient, then it should be connected in parallel, that is, the positive and negative poles of the solar panels are connected together, and the negative and negative poles are connected together. This is a parallel connection. the voltage of one solar panel is not enough to charge the battery, then they must be used in series. The series connection method is that the positive electrode of the first block and the negative electrode of the second block are connected together, leaving. a positive electrode and a negative electrode to connect to the battery.
There is no so-called parallel or series connection when using two solar panels to charge a battery.
Introduction There is no so-called parallel connection or series connection when using two solar panels to charge a battery. There is a so-called parallel connection and a series connection. If the voltage of a solar panel is sufficient, then it must be "paralleled"
