SOLAR PV SYSTEM KLEINES HEIM WITH BATTERY BACKUP
Project lead: Project implementation:
Technology partner: In cooperation with: Host institution:
ABOUT THE PROJECT
This project is part of the worldwide dena Renewable Energy Solutions Programme coordinated by Deutsche Energie-Agentur (dena) - the German Energy Agency - and co-financed by the German Federal Ministry for Economic Affairs and Energy (BMWi) within the German Energy Solutions Initiative.
Project Host: Namibia University of Science and Technology (NUST)
The project is located at Kleines Heim Guesthouse of the Namibia University of Science and Technology (NUST) in the Namibian capital Windhoek.
Grid Connected Solar PV System with Battery Backup
The Grid Connected Solar PV System with Battery Backup combines the best of a grid-connected and an off-grid system. Most part of the electricity generated by solar power will be used by Kleines Heim.
Any excess power generated over and above the needs is stored and can be used in the evening or in the event of grid blackouts
When the grid fails, the hybrid system will be able to disconnect from the network and switch to "off-grid mode" drawing power stored in the battery bank to power Kleines Heim guesthouse and using the solar system to recharge the battery bank.
