Uniquely good!

alitiq uses a hybrid approach to generate PV forecasts that combines state-of-the-art machine learning techniques with the best numerical weather forecasts from ECMWF, DWD and UWC.


To predict short-term weather changes, alitiq runs its own AI model that uses data available in real time, such as satellite images.


Taking into account the generated output, alitiq adjusts the forecasts to account for known issues such as shadowing, systematic deviations, degradation, snow and much more.

And how is that to work?

What our customers are saying

Any questions?

Yes, you can also receive customised forecasts. As our calculations are based exclusively on calculations from weather models available at any time, we are not dependent on current measurements on site.

We can improve our forecasts if you send us your current generation data.

The forecasts are updated every 15 minutes, taking into account the latest weather data and your generation data. You can call up the forecasts as often as you like. There are no call-up limits.

Yes, because we do not interfere with critical infrastructure, your data is secure at all times.

No! Data is exchanged via an external interface of your choice, e.g. via API or sftp. This interface is provided by alitiq. This ensures the security of your critical infrastructures at all times.

Your customised forecasts can be accessed via a web interface (API) or via an sftp server provided by alitiq. This only requires a few lines of code in your programmes or scripts. We will be happy to support you.

Do you have any further questions? Then write to us at or to one of the two contact persons listed above.
