Definitely not "solarpunk" in the strictest sense but Star Trek - The Next Generation does depict many ideals of solarpunk. Sometimes directly, but often indirectly too (like scenes at Starfleet Academy).

One of the reasons I really enjoy Star Trek TNG is that it has that optimistic of the future vs many of the other Sci-Fi shows that often focus on a more dystopian universe (even if they're not strictly "cyberpunk").

There haven't really been many other shows I can think of that have the same tone as TNG. Definitely The Orville; but that's to be expected as it's pretty much a love letter to Star Trek.
