yeah that's an insanely expensive way of buying power!
assume 80% output in ideal conditions, *cold sunny day with 0 shadows),
200W panel is around 1200x750mm x0.8 =
160W, which will get you double the charge you need for a fridge, but remember, as soon as the sky is filled with clouds, even if its still sunny, output will dive to 30-40% from experience. also account for voltage and charge regulation, losing out there too, and more stuff to carry. way more expensive than a second battery and $100 isolator...
