Dongola Integrated Off-Grid Solar & Pumping System

Dongola, the capital of Sudan's Northern State, sits on the banks of the Nile and serves as a critical administrative and healthcare hub for the surrounding region. Like much of Sudan, Dongola faces acute challenges in both waste management and water access at its healthcare facilities. Medical waste incineration and clean water supply are non-negotiable requirements for any functioning hospital, yet both depend on consistent power — something the local grid cannot reliably provide.

The UNDP and the Global Fund identified an urgent need to equip a healthcare facility in Dongola with an integrated system that could power both a medical waste incinerator and a clean water pumping system — entirely off-grid. The challenge was designing a solar installation compact enough for the facility's footprint yet powerful enough to drive both energy-intensive operations simultaneously.

The system needed to operate autonomously, with battery storage sufficient to bridge overnight and overcast periods, in a region where ambient temperatures routinely exceed 45°C and where dust and sand ingress present constant challenges to solar equipment longevity.

MIMAH was contracted to supply, deliver, and install a fully integrated off-grid solar power and solar pumping system. We deployed a hybrid solar array comprising 620W and 710W TW Solar panels, paired with Dyness lithium battery storage and Solis inverters — a combination specifically selected for its thermal resilience and extended charge cycle longevity in extreme desert conditions.

The 25kW system was designed to serve dual loads: a medical waste incinerator and a solar-powered water pump. Our engineering team conducted a detailed load analysis to ensure the system could handle peak demand from both subsystems simultaneously, with sufficient reserve capacity to prevent brownouts during concurrent operation. Installation was completed in coordination with local UNDP and Global Fund representatives, with full commissioning, testing, and handover documentation provided.

The facility now operates a fully autonomous 25kW off-grid power system that reliably drives both its medical waste incinerator and water pumping infrastructure. The installation has eliminated the facility's dependence on diesel generators and unreliable grid connections, reducing both operational costs and carbon emissions.

Medical waste is processed safely and consistently, meeting international public health standards, while clean water supply has been secured for patients, staff, and the surrounding community. The project stands as a proven model for integrated off-grid solutions in healthcare settings across arid and conflict-affected regions.
