Hi Brian, I see where you're coming from. But I'd argue it's not that vital to push people forward on the larger solar farms. I'm confident they'll all get done, by the end of the year at least, since there's a finite set of them and they're highly visible. (We've gone from 138 to 538 solar farms tagged so far.) To my eyes, the quarterly project is already on track to be a big success - we started with 4k panels and now we have 69k.
But of course if people would like to map the outlines of the big farms then please do - indeed I've been doing some of that. I do actually have a CSV of the type you suggest, but it's a mess with personal notes. I can share it but not immediately (I was hoping to merge it back into the wiki list at [1]). In my experience, about 5% of the REPD entries, I don't see in any aerial imagery (so cannot map) and I don't know whether that means they're very recent or that they didn't get built. I've checked all the entries of 10 MW or more, so if others would like to help then a good starting point is items in the list [1] of less than 10 MW (e.g. between 5 and 10 MW - there are lots of those).
