Technical PV potential

The present files are used to compute the technical PV potential, combining the outputs of all previous processing steps. The processing is performed in the python script *compute_PV_output.pv*. As the final processing steps are only multiplications, it can be run on a single processing node in a short amount of time using xarray (10-15 minutes for 9.7M roofs).

The tilted radiation (considering shading and the sky view factor) is computed at the same time as the PV potential, and saved as a seperate variable in the netCDF output file. The script implements the following equations:

E_{PV} = G_t(t) * A_{PV} * eta_{PV}(t) * PF(t)

As a large number of input files are required, the file paths are modified directly in the script to avoid confusion.

Output file

PV potential is computed for each hour and each DF_UID, together with an annual potential for each roof. The specification is provided in "data/README.md" (PV potential)

Input file specifications

The following input files are required. For the specifications, refer to "data/README.md"

• TILTED_IRRAD_FP: Tilted radiation
• AVAIL_AREA_FP: Estimated available area (columns "DF_UID", "tilted_area" and "available_area")
• ROOFS_FP: Rooftop characteristics (columns "DF_UID", "NEIGUNG", "panel_tilt")
• EFFICIENCY_FP: Panel performance per roof
