I can also recommend Strong Democracy: Participatory Politics for a New Age by Benjamin R. Barber But start with the preface and the go directly to Chapter 7. The rest is nerd shit for political theory. It can be nice to know but will get quite boring pretty fast. But Chapter 7 will have you jump of your chair and start rebuilding your local community.

social ecology is very popular amongst solar punk fans and vice versa yes

I would say so, yes. If solarpunk is the aesthetic vision of the future we hope for, social ecology provides a political critique and path towards achieving that vision.

Homie, social ecology is about as solarpunk as you can get.

Also: please keep the solarpunk policing to a minimum.
