Create a REopt ground-mounted photovoltaic system from its footprint geometry (horizontal Rhino surfaces).

### Inputs

* **geo \[Required]**

A horizontal Rhino surface (or closed polyline) representing a footprint to be converted into a ground-mounted photovoltaic system.

* **name**

Text to set the name for the PV system, which will also be incorporated into unique PV system identifier. If the name is not provided, a random one will be assigned.

* **bldg**

An optional Dragonfly Building with which the photovoltaic system is associated. If None, the PV system will be assumed to be a community PV field that isn't associated with a particular building meter.

### Outputs

* **ground\_pv**

A Dragonfly ground-mounted PV system object that can be exported to a GeoJSON in order to account for ground-mounted photovoltaics in a REopt simulation.
