One example is the most classic solarpunk novel, the Dispossessed by Ursula Le Guin. It deals with the tension between a capitalist society (not really cyberpunk) and a anarcho socialist outer planet colony on the corresponding moon. It doesn't paint the alternative society as a perfect utopia. It has its strengths and weaknesses. And it deals a lot with the cultural chock of someone who travels between. It doesn't deal that much with environmental issues though. And I feel like Cory Doctorow's walkaway is a lot like this. I bought it but I haven't gotten into it. His writing style can sometimes throw me off a bit.
