I have read through all of it and it has helped me to pick the right stuff for our solar and batteries etc.

But I do not agree with all the advise, he seems to only accpet ONE way of doing it right. I believe the success for a good working system is to KNOW what you really need. Check how much power you really need and make sure you can satisfy the demand.
I read a lot of post when people slag solar or complain that they run out of power. Most of the time the shortfalls are easy to spot.

Our system runs with much thinner cables than the internet experts recommend. Since we have the solar and the batteries fitted, the EHU cable has not been used. I didn't use the almighty MPPT controller either and it's still working ok. Even on rainy days like today I see charge on the panel.
 
Didn't read it all, read for about half an hour then noticed the uppy downy thing on the right was still quite near the top so gave up.
We have a 40w free standing panel and as we're at a free Spanish aire I decided to put a towel on the roof and lay it flat while we go to the beach, there's no wonder people seem to recommend 100w panels, the output laying flat on the roof is roughly halved! I know it's September but that's a big difference. So 40w pointing at the sun is worth 80w on the roof.

I was looking at ways to mount the panel on a tilting bracket but gave up. It's not looking pretty and you still don't know which orientation you are going to park most of the time. Instead I fitted a second panel. Job done, whichever way I park.
 
i have 6x80wt panels on the roof and about 600amp of wet truck batteries . works for me . all winter is spain etc and most of summer .mind ay the moment i,m not using it as the house next door shades the trailer roof.i power things in the house off the inverter, run a lead into the house.
these days its never been cheaper to fit solar.i only use pwm reg cheap and it works. be nice to tilt the panels but then it could let everyone know you are camping /parking .
keep it simple it works .
but in the ideal world you need a big clear roof .
i could get 15 panels on mine but that would be greedy. ha ha .
