Local-first generation wants big interconnection transmission grids (for moving excess peak generation to off-peak timezones), and the federal government is way better capitalized to support these kinds of projects. State or even sub-State policy is way better suited to manage the highly heterogeneous landscape of generating power at individual homes, both because the problem is smaller $ but also just has a lot of little regional wrinkles (what power mix is best for the location, what does existing land-use look like, etc). All IMO of course, also the Federal gov't has done a lot to support basic research for solar on a very general level, I think it's just a difference of what scope best suits which governing body.
