How does Sunnyplans rank parcels for solar suitability?

Each parcel gets a SunnyScore from a model trained on the geographic features that distinguish built solar farms from unbuilt land — slope, irradiance, distance to grid infrastructure, and similar signals. Parcels are then filtered to those with at least 5 contiguous flat acres outside protected areas and wetlands, and ranked by SunnyScore.

What does "qualifying parcel" mean in Josephine County, Oregon?
