Hi all That's great news. By the way, I have some regions to propose, if anyone would like to be steered:
With my solar PV colleagues, we've discussed targeting a couple of specific regions. We're looking at the Midlands (because so much good mapping has happened there already) - but also the area around Exeter, because there's quite a lot of "reverse flow" (i.e. solar generation) in that region, and it's a useful case-study area for people working with the National Grid ESO. Exeter itself has been mapped to a good extent (30%), but it and its surrounding areas could take more: Teignbridge (1%), Mid Devon (22%), East Devon (4%). If anyone fancies looking over those regions, it could be v beneficial. Really great seeing all this mapping. I'm hoping to be able to publish some academic analysis of it all, soonish. - I'll certainly let you know when I've done so!
