Preconfiguration "Solar electricity production prediction"
The service (
https://doc.forecast.solar/api:estimate) allows you to predict PV electricity production based on the weather forecast for a given location (
GPS coordinates of the power plant) and the specified technical parameters of the solar power plant.
The service in free mode is limited:
- Number of 12 queries per hour.
- Predictions for this day and the next day only.
- Services requiring a paid ApiKey key are not available.
This preconfiguration can be activated when creating a new object (e.g. by
"New object ..." in the context menu of the object or by pressing the
Insert key after selecting the object).
This preconfiguration is included in the
"/ Technology / Photovoltaics" group.
This preconfiguration can be created in the
PmaFolder,
PmaRoot or
PmaPrototype object.
The preconfiguration creates an object of the
PmaFolder type with subobjects
PmaPanel named "
Graph",
PmaData and
PmaSequencer.
In the
PmaSequencer object at the beginning of the
GetSolarData method there are variables for setting the parameters of the solar power plant. The following script communicates with the service and stores the obtained data in a file and a
PmaData object. The communication repeats once per hour.
The panel contains four graphs that show the projected future electricity production from the data. The panel can be switched between light and dark backgrounds.
The preconfiguration is created including the panel (object of the
PmaPanel type) is functional also as
Web panel.
These configurators can be set before the preconfiguration is created:
| The name of created object | Name of the object created in the Pma object tree.
The maximum name length is 30 characters.
This is a system name, so it must contain only alphanumeric and must not contain any diacritics (i.e. national dependent characters), empty string, spaces and first character must not be a number.

| Enable as Web component | Specifies whether this object has to be registered as a Web server component
After the preconfiguration is created, the "PmaPanel > Web server > Enable as Web component" configurator will be set to this value. |
|---|
| PmaWeb object | Path in the Pma object tree to the object PmaWeb, PmaWebFolder or PmaWebLang where the registration is carried out.
Macro expression can be used for input (it is evaluated after the application is launched).
After the preconfiguration is created, the "PmaPanel > Web server > PmaWeb object" configurator will be set to this value. |
