A library used to simulate photovoltaic energy production using PVGIS
Project description
pvmodule
This library is a work in progress where the main objective is to create an easy to use and complete library to simulate photovoltaic energy production throughout multiple scenarios.
Defining the location
>>> from pvmodule.location import Location
>>> from pvmodule.pvgis import PVGIS
>>> Location = Location()
>>> location = Location.set_location('Lisbon')
>>> print(location.name)
Lisboa, Portugal
>>> print(location.timezone)
Europe/Lisbon
>>> print(location.latitude)
38.7077507
>>> print(location.longitude)
-9.1365919
>>> print(location.elevation)
10.93380069732666
Retrieving Hourly data from PVGIS
>>> from pvmodule.location import Location
>>> from pvmodule.pvgis import PVGIS
>>> Location = Location()
>>> location = Location.set_location('Oeiras')
>>> PVGIS = PVGIS()
>>> input, output, meta = PVGIS.retrieve_hourly(
latitude=location.latitude,
longitude=location.longitude
)
>>> print(output)
