I am not an expert in panpsychism, but for what I know:
1) the idea that everything has a degree of consciousness proportional to its complexity, introduces the problem of compound consciousness. How do they compose, how is each consciousness contributing to the overall, upper-level one? how is experience explained at the different complexity levels?
2) it is impossible to test whether something is conscious or not
3) the theory is more a philosophical framework for dealing with the mind/body problem, but it actually moves the problem forward on the assumption that 'because it is something physical, it has consciousness. Then complex things have complex consciousness'
