The study reported in this article aimed to deepen the understanding of the mechanisms driving the adoption and usage of solar photovoltaic (PV) systems in rural Malawian households, particularly among communities that have not received prior solar energy interventions. It used a qualitative approach to investigate the experiences of solar PV system adopters in Ntchisi, Malawi. The study included fourteen participants, and data were collected through observations and interviews, which were then analysed using thematic analysis procedures. The study’s findings indicate that many individuals in rural areas have installed solar PV systems that lack adequate training, resulting in potentially hazardous installations. The installation of solar PV systems in villages is motivated by several factors, including the lack of electricity, convenience, benefits, and personal interest in learning more about solar systems. The participants have highlighted numerous benefits of using solar energy, such as reduced costs, increased convenience, improved productivity, reliable energy access, and telecommunication services. However, solar PV systems are primarily limited to household lighting, phone charging, and powering televisions and radios; however, not for cooking purposes. The findings imply that governments in sub-Saharan Africa should provide training and guidance on the safe and effective use of solar PV systems, invest more in solar PV infrastructure to enable larger solar systems for cooking, refrigeration, and irrigation, and promote the use of solar energy through education and awareness campaigns to encourage greater adoption of solar energy.

Renewable energy mini-grids are considered a cost-effective way to provide electricity for a large proportion of the population in developing countries who do not have access to it. Compared with standalone home systems and national grid systems, mini-grids can potentially offer a better service. They can be deployed faster, making them essential for sustainable development, especially in rural and semi-urban areas of developing countries. However, mini-grids often face challenges regarding their resilience, and many fail to survive beyond their pilot phases. This paper aims to identify the factors contributing to the success of mini-grids and to identify common themes that can help existing and future mini-grid developments become more resilient and influence policy decision making. To achieve this goal, we developed a database of the status of mini-grids in Malawi, with the energy generation resource(s) of their installed capacity, enabling factors, and challenges. We undertook a more detailed investigation of two hydro mini-grid systems—Bondo and Chipopoma. We collected qualitative and quantitative data through literature reviews, site visits, interviews, and observations. The study identified 19 mini-grids with a combined installed capacity of 26 MW. Of these, seven had been abandoned, and one was under development. Several factors that affect successful mini-grid efficacy in Malawi were identified, including financial resourcefulness, technical resourcefulness, policies and regulations, community engagement and capacity building, cross-sector linkages, and institutional organisational frameworks. These factors need to be integrated into decision making by all stakeholders to ensure the enhancement of resilience and the sustainable development of mini-grids.

Purpose: This study aims to investigate the intricate relationships between a community energy system, water resources and biodiversity conservation, with a specific focus on augmenting community energy resilience in Bondo. The primary objective is to gain an in-depth understanding of how community members perceive and experience the challenges related to balancing the often-conflicting demands of energy, water and biodiversity conservation within this context. Design/methodology/approach: The research uses a qualitative approach to unravel the multifaceted dynamics of community energy systems, water resources and biodiversity conservation in Bondo. Data were collected through focus groups and direct observations, enabling a nuanced exploration of community perspectives and lived experiences. The subsequent analysis of this qualitative data follows established thematic analysis procedures. Findings: The study's findings shed light on the formidable barriers that impede rural communities in Malawi from accessing electricity effectively. Even in communities fortunate enough to have electricity connections, the lack of knowledge regarding productive electricity use results in community energy systems operating at significantly reduced load factors. Furthermore, the intricate challenge of managing a biodiversity hotspot persists, exacerbated by the densely populated peripheral communities' continued reliance on forest, land and water resources. These activities, in turn, contribute to ecosystem degradation. Originality/value: In a context where government-led management of forest reserves and game reserves has not yielded the expected results due to a multitude of factors, there arises a compelling need for innovative approaches. One such innovation involves fostering partnerships between the government and experienced trusts as lead organisations, providing a fresh perspective on addressing the complex interplay between community energy systems, water resources and biodiversity conservation. This novel approach opens doors to explore alternative pathways for achieving the delicate balance between human energy needs and the preservation of vital ecosystems.
