Simple Solar Question (kinda of a Poll ?)
If I have 200 watts on a polar mount now, and I track the Sun thru the day,....moving at least 3 - 4 times a day,......sometimes every hr if not doing anything any better, about how many watts would I...

RJ, you have an adjustable system.... why not measure the amps flat vs optimal tilted into some low batteries.
When I did the above posted tests, I used the Trimetric with only the solar across the shunt, and I had to leave lights on all day to keep the battery bank from charging up and skewing the results for the afternoon.
In fact, you only see a smaller portion of the "daily AH haul" that is available unless you are running loads to use those AH. Battery charging tapers off from:
- rise of battery SOC to near the "full" point at those low solar amps
-panel IV curve where higher panel=battery voltage reduces Isc.
The usual thing is for most of the action to take place earlier in the day till batteries rise in voltage. However, with a swivel contraption , you can get those morning results in the afternoon on days when it is clagged in for the morning and does not clear up till noon.
