It depends on where you live. I had solar heat as a kid, and I lived in far north America (St Paul area, Minnesota). Solar heat was on 2 hours a day and had to be shoveled off continuously, including roof panels. I would rate it a 1/10 for convenience and due to the short days, 1/10 for heat. Probably cost my parents 5000x what it benefited them and that was because 2 kids constantly shoveled off the panels on the roof, then dived into a snow pile from clearing the driveway (ok, that was fun). So yeah, I'm saying despite improvements, it still has serious problems in some areas. The other major issue is China requires manufacturing in China if you use their rare earth elements. When I worked on wind turbines, 90% of manufacturing was done and required to be done in China. The US still has the largest REE mine in the world, subsidized by the US military.
