Thanks pianotuna for this thread. It's been very informative so far to see everyones individual setup.

Can you confirm/clarify from experience how my "system" compares with reality using your figures please? ( I need more proof before totally believing in my system)
155w and 8.6 amps suggests flat panels. 155/130 x 8.2 = 9.8amps if tilted and pointed to get Isc.
If at 49N in May, then flat would be 155/130 x 7.2 = 8.6 amps mid-day so that comes out right. ??
The daily AH haul you can assume from the mid-day amps is more dependent on when and where, but 8.6 in May at 49N would get you
8.6/8.2 x 70 = 73AH. So by being full at noon means your usage is 36AH?
I don't understand at all how you can be fully charged before noon though. That 8.6 amps would be a noon max in my system, but if the batts are full, the amps would be down to a trickle. In that case your peak amps would be mid-morning when the sun is lower and would be less than 8.6. What am I missing? Thanks.
