Solar energy bags

SunnyBAG bags and backpacks turn sunlight into electricity

About this project

SunnyBAG, located in the Austrian city Graz, is a producer of innovative shoulder bags and backpacks. They convert sunlight into electricity, allowing owners to charge mobile devices such as smartphones and tablets while they are out.

Bags with solar charging units getting an export hit

The EU’s COSME programme provides finance for SMEs – the backbone of Austria’s economy. One example is SunnyBAG, a start-up from the Austrian Styria region. Founded in 2010, it develops and sells shoulder bags and backpacks with integrated solar panels. This allows owners to charge mobile devices using solar energy while they are out. Support from COSME and Austria Wirtschaftsservice in 2013/14 led to continued success and global expansion.

“It can be difficult, for small companies in particular, to finance research. The financial support came just at the right time for us. It allowed us to make further product developments, plan a new system and open a branch in the USA. We needed support in order to keep on growing,” says founder Stefan Ponsold. As well as making practical products combining innovative technology with sophisticated design, SunnyBAG is aware of its social responsibility, working closely with Doctors Without Borders.
