DJ,
I started out with 190W(2X95W) panels to power everything which includes the biggest draw, my fridge/freezer. 4.7 amps when cycling. I noticed that when the day/night temps went over 90/65F, the fridge was sucking the batteries(4AGM,400amp/hr)even in the day sun. Installed another 140W panel and haven't looked back. Have plenty of power for my wifes hairdryer, some micro use, toaster, coffee grinder, blender, jacks, roof, electronics, late night led's.
My advise is to double what you think you might use. That is both solar and batteries.2 years and genny hour time can be counted on one hand.
