sonnen Human Rights Line

Welcome!

Through this whistleblower system, you can report misconduct that leads to violations of human rights or environmental due diligence obligations. Thank you for your cooperation.

Procedural Rules

The sonnen Human Rights Line is open to all individuals for complaints related to violations of applicable laws, the sonnen Holding GmbH Policy Statement on its Human Rights Strategy, or other policies. Complaints can be submitted anonymously or with contact details. Upon receipt of a report in the whistleblower system, the submitting person will receive an email confirmation. The report will be processed by a responsible employee. The individuals entrusted with conducting the procedure are required to act impartially. They are independent, bound by confidentiality, and not subject to instructions. If circumstances require, other departments and individuals may also be involved in addressing the incident.

The complaint procedure has been designed to ensure the confidentiality of complainants' identities and to provide effective protection against disadvantage or punishment as a result of a complaint. sonnen places great importance on maintaining the confidentiality of those reporting and preventing any disadvantage or punishment due to a complaint.

Through the Shell Global Helpline, employees and stakeholders can raise concerns and report instances of potential violations of our values and principles.

To ensure we are aware of and respond to all suspected violations, the Shell Business Integrity department manages the Shell Helpline for sonnen and contracts NAVEX Global, an independent company that receives information and complaints about potential violations of laws, regulations, the Shell Code of Conduct, and the SGBP via internet and telephone lines.

Reports received via the Shell Helpline are forwarded to authorized individuals within the Shell Group who ensure they are handled professionally and confidentially. Reporters are asked to provide their identity so that their inquiry or concern can be addressed as effectively as possible, but anonymous reports will also be processed. The Helpline is available to Shell customers, suppliers, partners, consultants, and employees.

What is the Shell Global Helpline?

Through the Global Helpline, Shell employees and other individuals can confidentially raise concerns or dilemmas, or seek advice on matters related to compliance with laws, our Shell General Business Principles (SGBP), and the Code of Conduct, without fear of retaliation.

Who can use the Shell Global Helpline?

The Shell Global Helpline is for all Shell employees and contract staff, as well as third parties with whom Shell has a business relationship (e.g., customers, suppliers, representatives), if they observe misconduct by a Shell company or employee.

Accessibility Information

sonnen Holding GmbH is committed to making its digital offerings accessible to all. This applies in particular to the sonnen Group’s websites (www.sonnen.de, www.sonnen.com.au, www.sonnen.eg, www.sonnen.es, www.sonnen.it, www.sonnen.nl, www.sonnen.pl, www.sonnenusa.com, www.sonnen.se etc.), the associated online services, and the Group’s mobile applications (such as the sonnenApp, etc.).

Our efforts are guided by the provisions of the German Act on Strengthening Accessibility (BFSG), the associated statutory ordinance, the EN 301 549 standard, and the Web Content Accessibility Guidelines (WCAG) 2.1 at conformity levels A and AA.

Through our digital platforms, customers can access information about the sonnen Group’s products and services, submit inquiries, and enter into contracts online. This includes, among other things, using the website and the sonnenApp to access information on energy storage solutions, electricity rates, and services; using online services to manage customer accounts, change rates, and update contract details; and using mobile applications to control and monitor energy storage systems and participate in the sonnenCommunity. In addition, free materials such as product information, white papers, and brochures are available for download.

Our digital offerings are designed to be as accessible as possible. Navigation is clearly structured, forms are easy to understand, and operation via keyboard and screen reader is largely possible. We also ensure that contract documents, privacy notices, and terms and conditions are accessible. After completing orders or registrations, a confirmation email is provided in an accessible format.

The services offered by sonnen Holding GmbH largely meet the requirements of the BFSG, as well as the EN 301 549 standard and WCAG 2.1 at conformity levels A and AA. Currently, there are still areas that are not fully accessible. These are being adapted step by step. These include, among other things, alternative text for some images in order and service areas that is still missing, insufficient color contrast on individual pages, limitations in keyboard navigation and screen reader support in certain submenus and mobile applications, incomplete semantic markup in forms, illogical focus order in mobile views, and limited compatibility of certain dynamic content with screen readers.

The sonnen app contains detailed data charts designed to support the analysis of various energy flows within the ecosystem. Although significant efforts have been made to improve the accessibility of these components, the inherent complexity of the graphical data visualizations may result in certain accessibility limitations. A data export feature with numerical data is available. We continuously review and improve these features to better support users with diverse needs.

We are continuously working to address these issues and are committed to continually strengthening and further improving the accessibility of our digital offerings.

The BFSG does not apply to recorded audio and video content published before June 28, 2025; to documents such as PDF files or presentations posted online before that date; or to third-party content not created or funded by sonnen Holding GmbH. Archived content that is not updated after the effective date is also excluded.

This statement was created on August 27, 2025, and updated on July 3, 2026. The evaluation of our digital services was based on an internal review as well as supplementary external tests.
