Timestamps
Overview¶
-
Supported by Pandas
- Arbitrary time series supported by Pandas' DatetimeIndex
- Relevant input parameters :
start_time,end_time,periodsandfrequency.
Seealso
Learn more about frequency strings at Offset aliases.
-
- Support for valid time zone identifiers from the IANA Time Zone Database
-
Defaults
Attention!
-
If not given, default time is
00:00:00. No solar irradiance at this time ! -
UTCis the default timezone in which internal calculations are performed anyway. -
Frequency of timestamps is unrelated to the
groupbyoption !

Working examples
Example
- Examples that should just work
PVGIS relies on the excellent timestamping engine of Pandas.
We can use all of the flexibility to build almost any kind of series of timestamps!
Optional parameters¶
The basic entrypoint for timestamp/s is the positional argument timestamps.
Notwithstanding,
a series of optional input parameters offer the flexibility to generate custom
series of timestamps. These are :
--start-time: a starting timestamp--end-time: an ending timestamp--periods: the number of timestamps within a time range starting with thestart_timeand ending with theend_timetimestamp.--frequency: Pandas frequency. Check here the documentation.
Frequency
When data are used their frequency is being guessed and respected by the CLI.
Examples¶
Local time and zone¶
Interested for the photovoltaic power output at your current local time and zone ? Just ommit the timestamp altogether !

Using the system's current time and zone!
The above example expectedly picked up the time and zone of the virtual computer on which this very page has been build after some change commited in the source code tree!
Missing positional parameters?
Remember, a specific user-defined timestamp, or list of timestamps separated by comma for the matter, would fail due to absence of all required positional arguments, i.e. :
Usage: pvgis power broadband [OPTIONS] {longitude} {latitude} {elevation}
[surface_orientation] [surface_tilt] [timestamps]
Try 'pvgis power broadband --help' for help.
