LASTING IMPACT SUSTAINABLE OFF-GRID SOLAR DELIVERY MODELS TO POWER HEALTH AND EDUCATION

The report analyzes the sustainability of off-grid solar PV systems in public health and education facilities across Sub-Saharan Africa and South Asia. Using a framework based on three pillars—organizational, technical, and economic sustainability—and four project lifecycle phases, it examines seven retrospective case studies and several emerging and hypothetical models. Key findings highlight that many systems fail within 3–5 years due to a lack of long-term operation and maintenance (O&M) planning, insufficient funding for component replacement (especially batteries), and a tendency to devolve responsibility to under-resourced local actors. The report argues that sustainability requires aligning public and private incentives, securing lifetime funding upfront, and utilizing centralized O&M management or performance-based private contracts to avoid the 'responsibility vacuum' that often occurs after initial project funding ends.

• Many off-grid solar PV systems in public facilities fail prematurely, often becoming inoperative after 3–5 years if proper maintenance and repair services are not provided.
• Organizational sustainability is often undermined when project 'Champions' transfer O&M responsibilities to local actors who lack the necessary human, technical, or financial resources to maintain the systems.
• Technical sustainability is frequently compromised by inaccurate energy audits that fail to account for behavioral changes and unanticipated load growth once reliable electricity becomes available.
• The use of antiquated battery technologies is a primary driver of system failure; the report notes a lack of large-scale deployment of more durable lithium-ion solutions despite falling costs.
• Economic sustainability is rarely achieved through local revenue-generating activities, as income from surplus energy is typically insufficient to cover full O&M costs and battery replacements.
• Effective sustainability requires O&M planning and funding to cover the full 10- to 15-year technical lifespan of the assets, rather than the shorter 3- to 5-year window of typical development project funding.
• Centralized O&M management by well-resourced organizations can be more effective than decentralized models, as demonstrated by the CREDA case in India where all 984 systems remained operational.
• Emerging models like KOSAP in Kenya and ROGEP in West Africa attempt to improve sustainability by using performance-based O&M contracts with private service providers and guarantees (such as from MIGA) to secure payments.
