Pedroni panel cointegration test

Hello!!
I am doing a panel cointegration analysis and implement pedroni's panel cointegration tests.
I have a question regarding my results. Only the panel v-statistic rejects the null hypothesis of no cointegration.
Pedroni(2004) says:
"if the panel is fairly large so that size distortion is less
of an issue, then the panel-v statistic tends to have the best power relative to
the other statistics and can be most useful"

My question is,since I have 41 T and 64 N, do I have a large sample size?

Thanks

PS. The results are provided below.
