Photovoltaics can power every home

This is

With SOLMATE, everyone will be able to produce their own electricity. Just set it up on the balcony, plug it into a power socket and provide your own renewable electricity for your household. SolMate is the first solar storage for the power socket.

SOLMATE – Bring sun into your home!


Your Solar Storage System without any installation, just plug it into the power socket!

Solar Energy System SolMate from EET for the power socket.
Solar Energy System - SolMate for the powre socket, made to use it on your balcony.

Solar Energy from your Balcony

The solar panels are attached to the balcony railing like a privacy screen, connected to the storage by cable and plugged into a standard wall socket. This self-generated electricity is fed back directly into this socket and is available in the entire apartment – without any construction site in your home, without any fitter or tons of paperwork.

PV Storage SolMate - with flexible solar panels for your balcony


for every home

With SolMate, tenants and owners of apartments are now also able to produce and use their own renewable electricity.

self consumption

Due to the smart solar storage, low feed-in tariffs are a
thing of the past.

The unused, green electricity is saved for when you need it!

solar storage for the power socket. Feeds electricity through the socket into your home net. Also able to use it off grid.

Save costs
and your environment

SolMate produces up to 25 % of the electricity needs of your household and thus saves about 6700 kg CO2.

Your electricity holds up to 80% less pollutants than conventional electricity!

backup system

Even in case of power failure, your SolMate still delivers solar power and supplies the most important devices in your household.

If you produce your own electricity, you are never sitting in the dark!


SolMate solar storage system - measurement to detect if and how much electricity is needed in your home

What makes SOLMATE

The products’ technological innovation lies within the measurement technology, known as NetDetection. During their time at Graz University of Technology, the EET founding team developed the technology and registered it at the European Patent Office. NetDetection allows your SolMate® to detect if and how much electricity is needed in your home – it does so through the socket it is connected to – without additional hardware in the meter box and without an electrician.
SolMate® knows if you need electricity and when it should feed it into the home grid. If no electricity is consumed, SolMate® stores your green electricity in the compact energy-storage unit for later.
The problem of low feed-in tariffs and complicated paperwork are things of the past.
With SolMate® you benefit from100% of the electricity you generate.

My SolMate

Of course you always want to know what your SolMate is doing at any given point, how much sun it is getting and how much power it provides. That is why we have developed a mobile app for smartphones and tablets. The “My SolMate” app is provided free of charge.
