Photovoltaic diesel hybrid solution for village power supply

Even today, many villages in Africa, Asia and Central and South America are not connected to the national grid. A village power supply can offer these people access to electricity.

Off-grid systems can provide the answer – that is, photovoltaic systems which are only partially connected, or completely unconnected, to the national grid. Particularly in very sunny parts of the world.they are ideally suited to electricity generation, Application areas range from small standalone systems, to the construction of an entire village power supply system.

In a photovoltaic diesel hybrid system, a diesel generator acts as an additional power source to back up the photovoltaic system. The diesel generator is regulated by a controller and only runs when more power is required, than the photovoltaic system can generate. This comprehensive system, therefore, offers a secure and affordable solution for long-term energy supply to both small and large off-grid communities.

Reference project: PV diesel hybrid solution for a hospital in Afghanistan

In cooperation with G.E. Consultancy and the local installer from Zularistan Ltd., BayWa r.e. supported the construction of a photovoltaic system on behalf of the Aga Khan Foundation Pakistan. The photovoltaic diesel hybrid system was specially developed to supply power to the first hospital in Bamyan Province. The aim was to reduce the consumption of diesel and make the hospital more independent in terms of its energy supply.

Thanks to the optimised design of the photovoltaic system with an installed capacity of 400 kWp and a powerful 1728 kWh battery storage system, the hospital is able to draw most of its electricity from solar energy. The diesel generator only starts up at night, once the capacity of the batteries is exhausted, and it continues providing power until the following morning.

As one of the largest system suppliers of its kind, BayWa r.e. was not only commissioned to supply the individual components. Together with local partner Zularistan Ltd., we were also responsible for the installation, commissioning and technical support on site.
