Solar production forecast and weather forecast data are provided for up to 7 days with a resolution of 1 hour down to 15 minutes.
If you then checked the documentation and you like it, register an account to more features.
As example you can take a look at my data logger which compares the actual production and the forecast data.
A good match of forecast and actual production can you find at the 2nd of November 2015.
You can easy build and test the required URLs with the Swagger-UI.

With the increasing share of photovoltaics in the electricity market, the importance of Solar energy forecasts. These are an important tool for the integration of Solar power into existing network structures.
The production of solar power is dependent on external influences on which man has no or only limited influence. For example, Season, time of day, weather (eg ambient temperature, clouds, air turbidity).
A solar day covers the global energy supply for eight years.
Predictions about the availability of solar-generated electricity in the future support private power management, but are of great importance, above all, for commercial solar power generators and network operators.
