Global data and AI leader SAS helped Let There Be Light International better understand how solar electrification affects health care and daily life in rural Uganda. Through a Data for Good project, SAS employee volunteers analysed years of clinic and household data to measure what changes after the lights come on.

The analysis linked solar power at rural health clinics with longer service hours, more attended births and greater patient access. Electrified clinics reported an average of 11.5 additional operating hours per day, 107.3% increase in attended births and 48.9 more patients each week.

“Previously we had no reliable light and this affected our maternity service delivery at night,” said Sylvia, a midwife at a Safe Births + Healthy Homes clinic. “But with the solar lamp incentive, clinic births have more than doubled within a period of less than a year. We are happy to have a reliable light source to better handle deliveries at night and not spend money on buying disposable flash torches and kerosene. We have high hopes that many more mothers will be delivering at the health clinic instead of going to traditional birth attendants."

Let There Be Light International works to address energy poverty by bringing solar power to rural health facilities and homes. Its Safe Births + Healthy Homes programme supports maternal and infant health while helping families access safe lighting after mothers and newborns leave the clinic.

Two volunteer teams examined different parts of that work. One team analysed whether electrified clinics could remain open longer, support more births and serve more patients. A second team studied participant data from Safe Births + Healthy Homes programme data to better understand how solar lighting affected the health, safety and daily routines of mothers and their families.

For clinics, the findings show that the value of electricity extends beyond infrastructure. Additional operating capacity gives health workers more opportunities to provide care after sunset and respond to the needs of mothers, newborns and other patients.

“The real value of analytics was in connecting infrastructure to outcomes that matter to people,” said Naveen Sundaresan, SAS Technical Support Engineering Manager and project volunteer. “Electrification is not just about whether a clinic has power; it is about whether that power translates into longer operating hours, greater patient access, stronger maternal health capacity and more reliable care.”

"SAS analysed more than a decade of data, giving us a clearer picture of how solar power improves health and health care in off-grid communities and who benefits most,” said Hannah Schulman, Director of Programmes and Impact at Let There Be Light International. “Better understanding what really works to support mothers, clinic staff and whole communities helps us strengthen our programmes. It allows us to partner more effectively with local stakeholders and advocate for expanding solar safety net programming so that no one is left behind."

The household analysis included responses from 3,519 families. Of those surveyed, 88.1% reported improved health at home, while 56.9% reported reduced symptoms or illness. Families also described safer nighttime household chores and activities and greater confidence caring for children after dark.

The clinic and household findings give Let There Be Light International a clearer view of the outcomes associated with solar electrification. By combining clinic results, household experiences, illness patterns and geographic information, the organisation can better understand past impact and make more informed decisions about where future support could have the greatest value, how to replicate elsewhere and how to best support communities.
