and, following the conclusion of an agreement with Fronius based on these SOLAR.WEB API Terms
of Use (the Fronius order forms refer to these SOLAR.WEB API Terms of Use) on the API, shall
receive access to data, which a Fronius product collects, in order to use these data or make them
available to its customer. If personal data of the Contract Partner’s customer are processed and the
Regulation (EU) 2016/679 on the protection of individuals with regard to the processing of personal
data (hereinafter GDPR) applies, Fronius shall act as a processor for the Contract Partner (as
defined by Art. 28 of the GDPR) and the Contract Partner assures Fronius that it is entitled to
process the data of the Contract Partner’s customer (in particular pursuant to Art. 5 et seq. of the
GDPR). See the additional data protection regulations in Point 7.
1.3. By ordering or using the Fronius SOLAR.WEB API, the Contract Partner recognizes (and
guarantees that the users are committed to complying with the SOLAR.WEB API Terms of Use) the
exclusive validity of these SOLAR.WEB API Terms of Use. The Contract Partner’s general terms
and conditions or similar, which differ from these Terms of Use, do not apply.
