Describe the bug
The papers and podcast episode below suggest that average land use per MW should be more like 5 - 10 acres/MW, where as detailed PV suggests 3 acres/MW, and PVWatts suggests 9.4

To Reproduce
Steps to reproduce the behavior:
- Open default cases as described above
- Change DC system size to 1 MW
- See error
Expected behavior
Land use calculations should lead to results consistent with the above resources, and be consistent between models
Total Module Area
Consider using same convention for PVWatts and Detailed PV: PVWatts "Estimated total module area" and Detailed PV "Total module area" shown on System Design page should be total of all module areas rather than total module area projected onto ground, i.e., not be affected by GCR. GCR should only affect land area in acres/ha on PV Land Area form.
-
Verify that this approach is consistent with all uses of GCR: Self shading, backtracking, and land area for both Detailed PV and PVWatts models.
-
Note module area on Detailed PV Module and Shading and Layout page: Total module area on system design page should be area of single module times total number of modules.
