Hi all, Thanks for the comments on solar panel mapping. (Plenty of mapping happening already: thousands of UK solar panels added to the database in the past month.) A few small responses:
SOLAR FARMS: I'll defer to Russ's tagging advice about solar farms: power=plant polygon (or sometimes multipolygon) as the outline of a solar farm, with power=generator areas contained within it for the blocks of panels. Previously, I was mapping solar farms as relations, but I'm easily persuaded! I don't have any advice about landuse/landcover other than that it's a fairly separate issue, since those tags are not essential to the solar power mapping. I've been adding some solar farms that are listed in the REPD list on the wiki. For those ones I've used a tag "repd:id=*" which I hope makes it easy to identify them using the ID number in that database. Some solar farms have more than one entry in the REPD (they submit a new application form when they have an expansion). ROOFTOP SOLAR: For various reasons, if we can get solar installations mapped as areas not just nodes, that'll be helpful. Areas will be more useful than module-counting. However, I've noted that the imagery doesn't always make this easy for rooftop solar: clarity is variable per region. Is there any good way to tag the vertical tilt of a panel? I know in many cases we won't be able to measure it well, but I thought I'd ask. For example, there's roof:angle=* for the slope of a roof, which is a mildly related concept.
