Examples here use the estimate
mode, you can replace it with history
for historic data or with clearsky
for theoretic results for clear sky weather.
Get solar production estimate for specific location (defined by latitude and longitude) and a specific plane orientation (defined by declination and azimuth) for an installed module power.
historic
means here that the average of all years of the available weather data on that day is considered, the current weather is thus not included in the calculation.
If there were no clouds it would be a clear sky. clearsky
thus calculates the theoretically possible production.

You can poke around with the Swagger Editor to build proper request URLs.
There are also routes available to query only the watts, watt hours or watt hours per day.

The watt_hours
data will simulate a daily electricity meter and therefor resets to 0 at day change!
