We have developed the SUNCheck app for RWE in addition to the solar calculator. This means that sellers and craftsmen can quickly calculate the specific yield as well as determine roof pitch and orientation in the customer discussion.

In an extended version, the app can also calculate the actual savings potential and the internal consumption rate. The app is available for iOS and Android and can be flexibly adapted to your corporate design.


The user is guided comfortably through the APP by means of simple inputs and can thus get a good impression of the possible yields of a future PV system – even without any prior technical knowledge. The resulting interest benefits the provider of the APP directly as lead.
