4. Source Code Availability (GPL/EPL)

Some components may be licensed under copyleft licenses such as GPLv2 (MariaDB) and EPL-2.0 (OpenEMS Edge). If you distribute these components (including as container images) you may be required to preserve license notices and, depending on the license and your modifications, provide access to corresponding source code.

4.1 MariaDB (GPL v2)

MariaDB Server is licensed under GNU GPL v2.0. If MariaDB is distributed as part of Solar Cube (e.g., preinstalled container), Solar Cube will provide or make available the corresponding source code as required by GPLv2.

4.2 OpenEMS Edge (EPL-2.0)

Solar Cube uses and distributes OpenEMS Edge only, which is licensed under Eclipse Public License 2.0 (EPL-2.0). EPL-2.0 typically requires preserving license/copyright notices and, if you distribute a modified version of EPL-licensed files/modules, making the source of those modifications available under EPL terms.

Solar Cube will provide the source code for any modifications to OpenEMS Edge (if such modifications are distributed) as required by EPL-2.0.
