## Photovoltaic(PV) Systems JSON-LD Description

This json-ld template is used to store metadata information commonly used to describe photovoltaic (PV) systems. There is information included on the location, modules, time series measurements, electrical properties, and weather conditions.

Note that a lot of the material included in this json pulls from the OrangeButton Taxonomy.

## Creating JSON-LD for PV Systems in R

    library(FAIRmaterials)

    # An example data frame for PV Systems
    system_example <- data.frame('Latitude' = c(30.1702, 28.32048),
                                 'ProdMfr' = c('CSI', 'FirstSolar'),
                                 'SystemID' = c('s1435', 's1284'))

    # This will generate JSON-LD file for the example data
    output <- fairify_data(system_example, domain = 'PVSystem', saveLocal = TRUE)

## Creating JSON-LD for PV Systems in Python

    from fairmaterials.fairify_data import *
    import pandas as pd

    # An example data frame for PV Systems
    system_example = {'Latitude' : [30.1702, 28.32048],
                      'ProdMfr' : ['CSI', 'FirstSolar'],
                      'SystemID' : ['s1435', 's1284']}

    module_example = pd.DataFrame(system_example)

    # This will generate JSON-LD file for the example data
    output <- fairify_data(system_example, domain = 'PVSystem')
