Renewable energy affordable, easy and reliable – that is what we – the Austrian start-up EET – are realizing with our SolMate.

SolMate is the first photovoltaics and storage system, that can be installed by anyone by simply plugging it in. It consists of five lightweight, semi-flexible photovoltaic panels and a small storage device. The panels are put on a wall, balcony, fence, etc., connected to the storage device, which is simply plugged into a regular wall socket. SolMate is able to save up to 25 % of an average household’s energy cost and approx. 7 tons of CO2 over its lifetime. Our smart storage system is on-grid and off-grid capable, meaning it still provides solar energy, even if there is a blackout.

SolMate produces renewable electricity and provides it to the household when it is needed. The intelligent power injection is based on our patented measurement technology.
Our team has now over 15 permanent employees and continues to grow. With the support of the two Austrian strategic investors Klaus Fronius (Fronius) and Michael Koncar (VTU) our start-up got even more momentum.

Our team

EET – Efficient Energy Technology was founded on May 9th, 2017 by Florian Gebetsroither, Christoph Grimmer and Stephan Weinberger under the name E2T. The core technology has been developed at Graz University of Technology, hence EET is a University spin-off. After only a few months of development und publicity work, the young start-up caught interest of the first big companies as well as potential investors. In December 2017, the first round of funding was concluded with Mr. Klaus Fronius and Mr. Michael Koncar. With the assistance of those new partners, the dynamic within EET developed very well, resulting in a team expansion to 15 members.
