Humanitarian projects

Since 2011 we are developing new solar systems together with aid organizations (e.g. Doctors Without Borders) to accommodate the special requirements in conflict areas. For these cooperations, SUNNYBAG was awarded with the AidEX Award in Brussels. You can find all information in our Humanitarian Aid Catalog (PDF; 3 MB)
