I need to power a CPAP, about 30 AH and a NovaKool 4 cuft refrigerator. Power consumption on this is highly variable. On a hot day, upper 80s, it will chew through about 50 AH, but typical is under 30 AH. I also have LED lights that pull almost nothing. The other draw is charging for laptops and camera batteries, probably 10 to 20 AH. Typical day would be 80 plus AH. Two days would draw my 300 AH batteries to about 50 percent.
I don't seem to lose charging in the winter, but I do lose because the days are short and the sun is low. I am sure tilting the panels would help but I am not going to consider getting on the roof to make adjustments.
