  • Re: why solar panel can use maximum 72 cell?

    BB.BB.
    A 72 cell panel has Vmp~36 volts (working voltage of panel). There are panels with higher output voltage. And the higher the voltage, the smaller copper cable needed (savings in copper costs). For gr…

    "Stay" was an auto correct on my phone... Was supposed to be "array". More or less, you have "two" 48 volt battery banks that are connected in series to 96 volts. You at…
