Well, the Wiki article that you cite answers your question for you:

"RTGs are usually the most desirable power source for unmanned or unmaintained situations needing a few hundred watts or less of power for durations too long for fuel cells, batteries and generators to provide economically, and in places where solar cells are not viable."

The space station needs more than a few hundred watts and solar cells are definitely viable. And there is no radioactive fuel to deal with.
