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. ...

Like BFL said - it's all about scenario. Latitude, climate, energy needs.
There is not much shade in SoCal, Az and Northern Mexico. Put 600W flat on the roof and you're good to go, no tilting or messing with portables. If it wasn't for controller box inside on the wall, I would forget that I even have a solar - it just works.
There is not much sun in BC and PNW. Put 1,000W on the roof and tilt it all you want, the harvest won't even cover small grey LCD clock on your radio when it rains.
There is not much harvest from 100W portable, you can't live on this source alone.
There is more harvest from 200W portable, but this is more panels to handle and it's still tough living on 200W even when tilted - doable but not always.
And so on.
