A surge in off-grid solar adoption is occurring across Malawi, but access to the technology remains unevenly distributed, with wealthier households disproportionately benefiting from the gains, according to new research. While solar uptake has increased significantly, the capacity of systems purchased by most families is limited, providing only enough power for basic needs like phone charging and lighting.
Malawi, a landlocked nation in southeastern Africa, faces significant challenges in providing electricity to its population. In 2023, only 16% of Malawians had access to electricity, a figure that drops to 6% in rural areas. The country’s grid relies heavily on hydropower, but outdated infrastructure struggles to meet demand.
Researchers from the University of Michigan, in partnership with the Malawian social enterprise Vitalite, surveyed 1,279 rural households in the Lilongwe District to assess the impact of solar technologies. The study focused on solar home systems – packaged kits including panels, batteries, and lights – and standalone solar panels. Their findings, published this year, reveal a rapid expansion in solar ownership, but also highlight disparities in access and capacity.
By 2023, 34% of households surveyed owned at least one solar product, a 4.5% increase from the previous year. However, adoption was strongly correlated with wealth. While solar is spreading quickly, the study found that most purchases are for lower-capacity devices. The median device capacity among those surveyed was just six watts, sufficient only for charging mobile phones and powering small lights.
Households with smaller capacity solar devices experienced modest improvements in quality of life, including reduced travel time to charging stations and increased hours of lighting. Many families reported using solar-powered lights for security purposes. However, more substantial benefits were realized by the minority of households that could afford larger, higher-capacity systems. These systems enabled some residents to power small businesses, such as barber shops and food stores, and extend lighting hours for commercial activities.
The research also revealed a link between solar adoption and financial inclusion. Solar-owning households were more likely to leverage mobile money services, facilitated by the ability to reliably charge their phones at home. These households were nearly twice as likely to participate in informal savings groups, leveraging mobile money for easier pooling and saving of funds.
The findings suggest that simply promoting solar technology is insufficient to achieve widespread, transformative energy access. Policymakers and donors should prioritize supporting access to higher-capacity solar systems, promoting modular expansion options, and improving financing mechanisms. Subsidies for low-income households and continued development of pay-as-you-proceed models are crucial for expanding adoption and ensuring sustained use of solar technologies.
Recent reports indicate that China is playing an increasingly significant role in providing off-grid solar solutions in sub-Saharan Africa, including Malawi. These systems are helping to address energy poverty in areas where grid extension is impractical or too costly. Simultaneously, funding cuts from the United States to HIV programs in Malawi and South Africa are raising concerns about the broader impact on development initiatives in the region.
