Solar Panels with No One to Fix Them

UNHCR and partners have deployed solar mini-grids and solar-hybrid systems across refugee settlements in Rwanda, Kenya, Uganda, and Bangladesh to replace diesel generators. These systems work well initially but degrade predictably: battery banks fail after 2–3 years, inverters overheat in tropical conditions, panels accumulate dust and damage, and connection points corrode. The fundamental mismatch is that humanitarian procurement processes are designed for one-time asset purchases, not ongoing service contracts with maintenance, spare parts, and eventual component replacement. Energy systems deployed for what was expected to be a short emergency response end up operating for 10–20+ years as displacement becomes protracted, far exceeding their maintenance-free lifespan.

UNHCR's solarization of boreholes has reached 50% of operations, and solar-hybrid mini-grids power health centers, schools, and water pumping across dozens of settlements. When these systems fail, the settlements revert to diesel or go without power entirely — disrupting clean water supply, vaccine cold chains, and night-time safety lighting. The investment in solar infrastructure is wasted, and replacement diesel costs exceed what ongoing maintenance would have required. An estimated 30–40% of deployed humanitarian renewable energy systems are operating below rated capacity due to deferred maintenance.

Training refugees as technicians (Renewvia Energy model in Kenya) helps but doesn't solve the spare parts supply chain problem — components must be imported with procurement timelines of 6–12 months, meaning systems sit broken. Pay-as-you-go solar home systems (Enter Energy model) shift maintenance to private operators but only serve individual households, not institutional loads. IRENA-UNHCR pilots in Rwanda demonstrated solar-diesel hybrid viability but relied on implementing-partner maintenance that ended when the project grant expired. The core problem is a structural mismatch between humanitarian funding cycles (1–3 year project grants) and energy infrastructure maintenance cycles (continuous, 20+ year lifespan).

A shift from asset procurement to energy-as-a-service contracts where private operators own and maintain systems with guaranteed uptime SLAs. This requires: multi-year contracting authority that humanitarian funding cycles typically don't allow; standardized equipment specifications across camps enabling regional spare parts inventories; remote monitoring systems that predict component failure before catastrophic breakdown; and business models that generate revenue from refugee and host community energy sales to fund ongoing maintenance. The technical components exist — the gap is in business model design for the humanitarian context.

A team could design a remote monitoring and predictive maintenance system for off-grid solar mini-grids using IoT sensors and cloud analytics, optimized for low-bandwidth connectivity. Alternatively, a team could model the economics of energy-as-a-service vs. asset procurement for a specific refugee settlement, using publicly available UNHCR data on energy consumption and system specifications. Electrical engineering, business/economics, and international development skills would be most relevant.
