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. ...

...And I also mentioned the situation when ZERO solar could serve somebody's particular needs as well.
The key word - in my post about 100W - was "live". Not necessarily fulltime, but reliably. If somebody's needs are 15AH, he can live on 100W that will get him on West Coast Lat 49 (for example) 35AH daily average, flat, in July. 30AH average in June. It doesn't matter (much) what is the maximum on a good day, it matters what it will harvest average (battery should be big enough to get you through the days below average, but this is another question).
Can be days and weeks when 100W at Lat 49 will harvest less than 15AH. More with tilting, but when flat output is 12AH, tilt would only increase it to 15AH. Living on 15AH? Sure, even on 0AH - when I was younger and there was no solar, I said it - my bad :)... Vast majority of members here would probably correct me that this was a surviving, not living.
For a fulltimer like Mr Wiz, with residential fridge, 100W or 200W is nothing, a stop-gap between generator runs while waiting to fix the big system on the roof. His (400W?) is still not big enough, considering his needs and days with "marine layer" on the coast.
