Cats come up a lot.
The artist (the closest-to-main character) has two cats,

(have you read Tweep? http://www.tweep.com/ hits something of a similar tone, maybe - is a group of friends getting involved in each other's lives and doing small things like going to the park, making mixtapes, taking photos and developing film ... not especially solarpunk, but nice.)
Sunbeam City is a anticapitalist, antifascist solarpunk instance that is run collectively.
