Dynamic fields might be an answer. If you had a field called "product_*" and these were populated with the corresponding values during indexing then faceting on these fields will give you the desired behavior.
The only catch here is that the product names have to be known upfront. A wildcard support for field names in facet.fl is still to come in Solr.
