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. There's usually a 
boundary fence around the whole site. There are usually 'blocks' formed 
from numerous rows of panels. There can be multiple blocks, often one 
per field.

Does a solar farm require a power=plant around the perimeter boundary? 
(no fill or border render, but the name is displayed in the 'standard' 

Does power=plant require a landuse=industrial tag (which does fill render)

Where should the power=generator tag be placed? On the individual blocks 
or on the perimeter boundary?
or, as in this detailed example, on individual panel rows? 

Similarly where should 'plant:output:electricity' go?
(There's another example, which I'm unable to locate at present, which 
had the power output on each row).

State side example:
Note they're tagged as buildings, & include the address!

Some UK examples have collected 'blocks' into a relation.
If there's a boundary around them all I feel this that is unnecessary as 
OSM is geospatially aware. Similar to the schools project, any object 
within the amenity=school boundary is assumed to be part of the school.
