    Unless the CIGS versions can significantly offset the low sun angle issues months the best way of overcoming the sun angle problems is to tilt the panels. With no tilt the peak sun angle at midday in mid winter in southern England is only about 30 degrees. At best normal solar panels can only produce half their rated output in those conditions. This becomes about three quarters in March and September. These figures get worse the further north you go and remember the solar day is a lot shorter in the winter months. The lower sun angle before and after midday adds to the losses. A recent side by side test done by two motorhomes last winter showed huge benefits by tilting the panels towards the sun.

    I’ve just fitted a 120w solar panel to the roof of my caravan, done it my self not a hard thing to do. Got a complete kit from sun store solar, well pleased as the battery is at full charge all the time.

    Trouble is, after explaining the difference between CIGS and silicon and the advantage of CIGS, you do not tell us which system is used in these panels!

    • Liz @ Caravan Guard says:

      The NDS 110W SolarFLEX has mono-crystalline silicon cells, as highlighted in the description.

    Very disappointing as the article made a big deal of CIGS yet no supplier or offer!

  6. Graham Stone says:

    I’ve used a 165w home PV panel, second hand and producing 45v in peak sun. Used via an adjustable Charge Controller it keeps the leisure battery and cab battery (via a battery master) in top condition.
    Total cost doing it myself, including fixings was no more than £250. It pays to shop around……!

    Interesting guide to commence further investigatio .
    Does put the question of whether solar, though ecologically good, is worthwhile. Wild campers …yes.
    Leisure campsite electric connection…no.
