Overview of the Sustainable Off-Grid Solutions for Pharmacies and Hospitals in Africa (SophiA) Project
Despite ongoing urbanization across Africa, the majority of the population still resides in rural and remote areas, where infrastructure development remains limited. These regions face significant challenges such as lack of access to healthcare, education, clean water, and reliable electricity, contributing to higher rates of illness and poverty compared to urban centres. According to reports, Sub-Saharan Africa has approximately 120,000 public health facilities (22,000 hospitals and 98,000 health posts), of which around 26% lack any electricity access, and only 28% have reliable power supply.
Access to good healthcare is critical for sustainable development. However, many rural medical centres operate under harsh conditions – using polluted water, lacking cooling for medicines, and facing poor sanitation – largely due to unreliable electricity and water supply. Although half of the population in Sub-Saharan Africa lacks electricity, the region has abundant renewable energy potential that can be effectively harnessed through off-grid solar photovoltaic (PV) systems.

To address the above-mentioned challenges facing the African Continent, Makerere University in partnership with 13 organizations across Europe and Africa developed a project titled, “Sustainable Off-grid solutions for Pharmacies and Hospitals in Africa (SophiA)”. The five-year project that began on 1st October 2021 is funded by the European Union (Project: 101036836 – SophiA – H2020-LC-GD-2-3-2020). At Makerere University, the project is coordinated by Dr. Nicholas Kiggundu, Associate Professor in the Department of Agricultural and Biosystems Engineering, College of Agricultural and Environmental Sciences (CAES).
Piloted in Burkina Faso, Cameroon, Malawi, and Uganda, SophiA aims to provide sustainable off-grid energy solutions to rural and remote health facilities, fostering economic growth and ensuring equitable access to energy and healthcare. Using various technologies, such as photovoltaics, solar thermal, electrical and thermal storage, water treatment and natural refrigerants with low global warming potential, SophiA has developed and manufactured locally innovative, modular, affordable and efficient solar powered systems for providing:
- Safe and clean drinking water, free of bacteria and viruses, and deionised water for medical purposes;
- Hot water and steam production for thermal requirements of the hospitals;
- Cooling of medicines and food at +5°C;
- Low temperature storage of blood plasma and vaccines at -30°C;
- Ultra-low temperature storage of sensitive medication (e.g. some Covid-19 or Ebola vaccines) at -70°C.

In addition, PV MedPort, a simple and 100% solar-powered solution has been developed and tested as a mobile health care station in small remote areas in 4 different geographical conditions in Africa. The SophiA system has been manufactured in Africa and will provide, for the first-time, innovative solutions based on climate-friendly natural refrigerants to cover cooling demand for three different temperature ranges (-70°C, -30°C and +5°C). The system has been tested and demonstrated at four rural hospitals in remote regions throughout the African continent covering the major geographical regions and different climatic conditions in Burkina Faso, Cameroon, Malawi and Uganda.
SophiA Project initiatives in Uganda
In Uganda, all Health Centre IV hospitals with surgical theatres have been connected to the national grid except Buvuma Health Centre IV, which serves over 120,000 people scattered across 52 islands. Recognizing this gap, the Ministry of Health selected Buvuma Health Centre IV for the SophiA project to demonstrate sustainable off-grid solutions.

The SophiA System at Buvuma Health Centre IV provides the following services:
- Off-grid electricity supply
- Safe, clean drinking water for patients, staff, and the community
- Hot water and steam systems crucial for maternal care
- Solar-powered cooking and meal preparation
