Wouldn't that only apply to fossil fuels? I would think the watts per square meter of any solar panel I buy is similar to that of one used in a solar farm. The

  private ones are often available as a little more efficient as the power/area and power/weight matters for things like RVs

    Actually thinking about it the conversion scheme (DC -> AC) used by the utility scale operator might be a bit more efficient. They'd care a bit more about getting that last 0.5% or 0.1% of gains than a residential customer.

      Conversion losses are on the order of 5-15% Splitting hairs, but a 23% efficient mono perc panel will edge out a 19% poly silicon panel even if utility conversion is a lot better. Although I think in that specific case the perc panels are cheaper now for utilities too. If you're using it at 12V and/or you shelled out the extra money for multi junction in your caravan you're probably still ahead. There will also likely be 5 years or so after hybrid perovskites hit the market before anyone is keen to put down big money on the lifetime predictions.

  The panels may be the same but mounting it on your roof may not be optimal for angle and shade reasons vs putting them in an open field.

    Yeah this is a good point. My roof used to be shaded for most of the day.
