Legal basis for the processing is the necessity to perform pre-contractual measures according to Art. 6 para. 1 b) GDPR.

Our newsletter regularly informs you about us and the latest news in the area of PV storage systems.

If you subscribe to our newsletter, we need a valid e-mail address. After entering your e-mail address and confirming the consent wording, you will receive an automated e-mail in which you once again confirm your consent by clicking a link (double opt-in). As proof of your consent, we store your e-mail address, the consent wording, the confirmation e-mail as well as the respective IP addresses, time and date of the registration and confirmation.

Legal basis for the processing is your consent according to Art. 6 para. 1 a) GDPR.

Our newsletters are sent through the newsletter service provider "CleverReach" - by CleverReach® GmbH & Co. KG, Mühlenstraße 43, 26180 Rastede, Germany. CleverReach stores the e-mail addresses of our newsletter subscribers as well as other data described in the following, if any, on servers. The data is used by CleverReach for sending out the newsletter as well as for statistical analysis on our behalf as well as for optimisation of their own services.
Furthermore, we concluded a so-called Data Processing Agreement with CleverReach according to which CleverReach commits itself to protect the data of our newsletter subscribers, process it according to its data protection regulations on our behalf and to not pass it on to third parties. You can view the data protection regulations of CleverReach here.

Our newsletters contain a so-called “web beacon”. This is a small file which is retrieved from the CleverReach servers when our newsletter is opened. On this occasion both technical information (e.g. about your browser and the time of your retrieval) as well as your IP address are collected and stored. This data is used by CleverReach for the statistical analysis as well as the improvement of its own services. Additionally, CleverReach can analyse the reading habits of the newsletter subscribers, in particular if and when our newsletters are being read and which links are being clicked. This analysis also serves the purpose of tailoring the newsletter offer as exactly as possible to the interests of the subscribers. Legal basis for the processing is Art. 6 para. 1 f) GDPR.

Your consent to the storage of such data as well as the use of your e-mail address for sending the newsletter can be revoked at any time. The revocation can be made via a link in the newsletters or via notification to us by e-mail. At the same time, this cancels your consent to receiving the newsletter through CleverReach and the statistical analysis of the data by CleverReach. A separate revocation of the consent to receiving the newsletter and the statistical analysis is not possible.

Web Analysis with Google (Universal) Analytics

Our website uses Google (Universal) Analytics, a web analysis service of Google Inc. ( Google (Universal) Analytics uses methods which enable an analysis of how you use the website, such as so-called “cookies”, text files that are stored on your computer. The information generated about your use of this website will as a rule be transferred to a server of Google in the USA and stored there.

Google Tag Manager

This website uses Google Tag Manager. Google Tag Manager is a solution operated by Google LLC. 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA (“Google”) that allows marketed website tags to be managed using an interface. The Tag Manager tool itself (which implements the tags) is a cookie-less domain and does not register personal data. The tool causes other tags to be activated which may, for their part, register data under certain circumstances. Google Tag Manager does not access this information. If recording has been deactivated on domain or cookie level, this setting will remain in place for all tracking tags implemented with Google Tag Manager.

Facebook Pixel

Our website measures conversions using visitor action pixels from Facebook, Facebook Inc., 1601 S. California Ave, Palo Alto, CA 94304, USA ("Facebook"). These allow the behavior of site visitors to be tracked after they click on a Facebook ad to reach the provider's website. This allows an analysis of the effectiveness of Facebook advertisements for statistical and market research purposes and their future optimization. The data collected is anonymous to us as operators of this website and we cannot use it to draw any conclusions about our users' identities. However, the data are stored and processed by Facebook, which may make a connection to your Facebook profile and which may use the data for its own advertising purposes, as stipulated in the Facebook privacy policy. This will allow Facebook to display ads both on Facebook and on third-party sites. We have no control over how this data is used. Check out Facebook's privacy policy to learn more about protecting your privacy: You can also deactivate the custom audiences remarketing feature in the Ads Settings section at You will first need to log into Facebook. If you do not have a Facebook account, you can opt out of usage-based advertising from Facebook on the website of the European Interactive Digital Advertising Alliance:


Google Ads (formerly Google Adwords)

We use the services of Google Ads to draw attention to our attractive offers with the help of advertising materials (so-called Google Ads) on external websites. We can determine in relation to the data of the advertising campaigns how successful the individual advertising measures are. We are interested in showing you advertisements that are of interest to you, to make our website more interesting for you and to achieve a fair calculation of advertising costs.

The advertising materials are delivered by Google via so-called “Ad Servers”. For this purpose, we use ad server cookies, through which certain parameters for measuring success, such as the insertion of ads or clicks by users, can be measured. If you access our website via a Google ad, Google Ads stores a cookie on your device. These cookies usually expire after 30 days and are not intended to identify you personally. For this cookie, the unique cookie ID, number of ad impressions per placement (frequency), last impression (relevant for post-view conversions) and opt-out information (mark that the user no longer wishes to be addressed) are usually stored as analysis values.

These cookies enable Google to recognize your Internet browser. If a user visits certain pages of an Ads customer's website and the cookie stored on their device has not expired, Google and the customer can recognize that the user has clicked on the ad and has been redirected to this page. Each Ads customer is assigned a different cookie. Cookies cannot therefore be traced via the websites of Ads customers. We do not collect and process any personal data in the aforementioned advertising measures. We only receive statistical evaluations from Google. On the basis of these evaluations we can recognize which of the used advertising measures are particularly effective. We do not receive any further data from the use of advertising material; in particular, we cannot identify users on the basis of this information.

Due to the marketing tools used, your browser automatically starts a direct connection to the Google server. We have no influence on the extent and the further use of the data which are raised by the use of this tool by Google and inform you therefore according to our knowledge: By the integration of Ads conversion Google receives the information that you called the appropriate part of our Internet appearance or clicked an announcement of us. If you are registered with a Google service, Google may associate your visit with your account. Even if you are not registered with Google or have not logged in, it is possible that the providers may obtain and store your IP address.
