Logu d'OpenStreetMap OpenStreetMap

I am gradually scanning imagery for the Albuquerque area to map photovoltaic solar panels–mostly rooftop, but I tag ground installations when I find them. At present the Mapbox Satellite imagery for the area bounded by I-40, I-25, the southern city limits, and San Mateo (and a line extending south to the city limits) has been scanned, and PVs within it have been tagged. I will update this as I systematically extend this area eastward and then begin areas north and west of the I-25/I-40 interchange.

Most PV installations in the area are on flat roofs, and can be detected only from aerial/satellite imagery. It is not uncommon for one rooftop to hold several sections of panels, separated by open roof areas. I am tagging each rooftop bearing PVs using a single point, even if the roof holds several areas of panels. There are also a few large installations holding large numbers of panels on the top surfaces of parking shelters. Where these are clearly part of one installation, as at the parking area for the Albuquerque Sunport, or at the VA hospital, I am again tagging each as a single point, with a note that it is a more extensive area. If guidance from the OSM community clarifies how to tag these, I will revisit these and remap them.

Hi Ed, I think the majority of people do tag them with lines or areas and not just a dot. Have a look at the wiki to find out more.

Hi Ed, if you would mind to draw the solar areas as areas it could simply be summed up to the total area of solar generators. Even with rather low accuracy and given the fact that you may only draw the orthogonal projection of elevated panels, perhaps ignoring their better sun/PV ratio, it can be a good guess of total installed PV area in a region. best regards!
