Assuming that the Solr node you stop does not contain all of the replicas for any shard, there should really be no effect. I do strongly recommend that you stop the node gracefully if possible unless what you really want to test is when a node goes away mysteriously...
What’ll happen is that all of the replica on the downed node will be marked as “down”. When the node comes back, the replicas on it will re-sync with the current leader and start handling queries and updates again. There should be no loss of data or data inconsistencies.
