Solar Powering Primary Health Care by Tim Mulé - Infogram 


This report focuses on rural and tribal regions of India to evaluate the ways that solar photovoltaic technology

can supplement their lack of energy access, in an effort to improve the health care available to those communities.

The report examines three separate case studies that have been carried out in India: the implementation

of solar photovoltaic systems into primary health centers in rural parts of southern India to combat issues of

intermittent or non-existent grid connected electricity, the deployment and analysis of solar direct drive vaccine

refrigeration systems in these same areas to preserve the potency of vaccines and medicines needed by these

communities, as well as an examination of a proposal for a solar powered boat ambulance to assist in providing

primary health care, supplies, and transport to isolated tribal communities in eastern India.


The study on the primary health centers has shownthat the implementation of solar systems in these facilities

has lead to an average 31% savings in monthly electricity bills and equal reduction in demand from electricity

from the grid, while increasing their overall reliability of electricity access. The solar direct drive vaccine refrigeration

field study has revealed that these systems are capable of keeping their contents within the required

temperature limits in the field, and surveys have shown they have many preferably qualities when compared to

conventional units. Finally the study of the solar powered boat ambulance has revealed that the latest evaluated

design would be able to service a distance of 25 kilometers in the month of the worst solar irradiation. This

would adequately serve the tribal population in the region and would aid in combatting the poor conditions

and undesirable health practices currently being implemented there.


The analysis of these cases involves the use MATLAB and Simulink software to determine the capabilities of

the technologies used and the benefits from their implementation. The analyses reveal the potential to improve

patient outreach and overall health of the communities in these isolated region by filling the gaps in their current

energy demand with solar photovoltaics. It is the hope that these learnings can serve as a reference for future

projects in India and other developing nations around the world.
