Thermal capacity to potentially reduce shift the actual time that the compressor runs the most; towards may day-time instead of night-time usage.
Total energy use-age may be actually more (as there IS significantly more thermal mass in the unit), however, if that use-age is shifted to the time when solar is available, then less battery capacity is actually needed.
It might also be neat to hack the refrigerator electronics and set a lower interior temperature during solar production, and elevate the temperature during periods without solar production.
