You are indeed right. Tagging for ground-based solar farms is varied. I am currently collecting them at https://wiki.openstreetmap.org/wiki/Renewable_energy_in_the_United_Kingdom#List_of_under_construction_and_operational_UK_Ground_Mounted_Solar_Farms without reforming the tagging and building up a tagging scheme in the process.
Use of a relation echoes that of a wind farm, which is a special case object made up of individual nodes (turbines), ways (substation), and lines (access tracks). The gaps in-between turbines are not physically part of the wind farm. A solar farm relation could be replaced with a boundary fence if one exists, with the blocks of panels as generators and the overall relation/boundary as power:plant. or you could be as detailed as our German colleagues..... https://www.openstreetmap.org/?mlat=51.5746&mlon=13.7358#map=15/51.5678/13.7384 On Thu, Apr 4, 2019 at 2:11 PM Dave F via Talk-GB <talk-gb@openstreetmap.org> wrote: > On 03/04/2019 17:23, Dan S wrote: > > * The tagging is already pretty well-defined. > > > This would be a great project, however I think there's some confusion in > the tagging which requires agreeing/clarifying. > > Most solar rural solar farms are on arable land.
