Tilting Solar panels makes a big difference!

I had 2 100 watt Renogy solar panels on my roof and they seem to only have an output of 3.4 amps each. I added a third panel and now the max is around 10 amps this time of the year for the 3 panels. I also have a Renogy Solar100 watt portable suitcase which has a max output of 5.5 amps. I laid it flat and it only added 3.7 amps but when I tilted it for max sun it rose up to 5.5 amps. I hope during the summer my max on the flat panels gets up to over 5 amps each.

    thats why so many RVs have 400w or more on the roof
    to make use of the minimal winter sun

    I think that solar power has some basic contradictions for RV's. The temptation is to mount them flat on top and then park in the sun. The results are best when you park in the shade and have your panels out and tilted towards the sun. But then you have to lug them around and worry about them during windy weather or when you leave your campsite.
