That's awesome you're using residential solar power. Have you experimented with community-scale CDR, like generating bio-char?
I have made small quantities of biochar experimentally, and I am considering making a 55-gallon drum sized burner (TLUD-style). I bought this place in 2021 and I have been using every scrap of biomass for composting so far - the soil here was very poor. Of course the biochar would help the soil too, but it won't support earthworms - I needed to kick start the soil organisms first. But all my neighbors mow every week and generate lots of grass clippings and little else. It will be hard to make that into biochar I think - green and dense - but I will eventually try. For now I have at least convinced several to quit bagging the cut grass and putting it in trash pickup.
