Energy storage technology firm REDT (Renewable Energy Dynamics Technology Ltd.) has installed a 5kW vanadium redox flow battery system with 12 hours (60kWh) storage capacity at the University of Evora, Portugal.
The project is part of the European Commission’s Seventh Framework Project (FP7), which aims to develop improved methodology, management, efficiency and cost reduction for renewable energy generated from solar PV installations.
The system has been installed in a building on the Valverde campus to supply stored solar energy to maximise the efficiency of a 6.6kW PV array on the roof.
Time shifting will be utilised with voltage and frequency control to maximise energy savings. The system can deliver 2kW load for up to three days during periods of low solar output.
