Granting consent is voluntary. Without this consent, the contact mediation function with installers is not available;
however, you can still use the platform for PV calculations.

You may withdraw your consent at any time with effect for the future. Withdrawal does not affect the lawfulness of processing carried out prior to the withdrawal.
To withdraw, contact: info@pv-energie-planer.de or use the corresponding function in your user account.
5.5 Installers' Own Responsibility
After data has been shared, the respective installer becomes the independent data controller for the processing of your data.
PV-Energie-Planer has no influence on any further processing by the installer. We recommend informing yourself about their data protection practices.
5.6 Consent Text
