I'm sizing up things ready for our new van, but am very conscious of a possible weight issue. I have been looking at solar panels but am having difficulty finding any information on how much power they actually produce. By this I'm meaning how many Amp hours do panels produce in a day. I know days are longer in the summer and the elevation of the sun is higher, not to mention weather conditions, but I have no information on this what so ever so many empirical data from users would be extremely useful.
I would like a system that would produce around 20Ah per day on most days, what size of panel will I need? I hoping the answer isn't measured in acres
Also would it be advisable to have a dual controller in order to also charge up the engine battery. Something like this:

I've never had a problem with my engine battery even when left unused for a couple of months in the winter, but the dual controller cost very little extra.
Many thanks
