    Series or Parallel solar panels? Advantage of Identical panels..

    You would need to start from scratch to keep identical panels,,
    Weigh that up against using every square foot of available roof space,,

    I have a300w and a250w fitted to the roof of my 79 series and because the panels have different speccs I have fitted a seperate MPPT controller to each of the pannels so that they can charge independantly, Much the same as would happen if I was to add another portable panel (with its own controller) to the mix.

    Seems to work just fine and running 2x fridges (1 freezer 1 fridge) plus lights off this stand alone system hasn't let me down so far.

    It also offers a redundancy in case one of the panels/MPPT controllers were to fail

    I've been looking at this. My OKA has old flex panels glued to the pop-top. They still work but the output could be better.... Short of either scraping them off or sticking more on top I intend to follow this and fit a solid panel to the roof of the cab. I hadn't considered two seperate controllers....
