Kweli Energy: 36 kWp Off-Grid Solar Power System Installed in Yei, South Sudan
Kweli Energy has completed the design, supply, installation and commissioning of a 36 kWp off-grid solar power system at Harvesters Reaching the Nations in Jansuk, Yei, Central Equatoria State, South Sudan.
The system provides stable, self-sustaining power for a large campus operating without reliable grid electricity.
The Challenge: Diesel Dependence and Unstable Supply
The campus includes a hospital, school, church, orphanage and staff residences. Power supply relied heavily on a diesel generator and an outdated solar setup that could not meet demand.
Interruptions affected hospital services, classroom activities and daily campus operations. Fuel costs were high, and generator use was constant.
The site required a reliable off-grid power solution capable of supporting essential services around the clock.
The Kweli Solution: 36 kWp Off-Grid Solar System with Lithium Battery Storage
Kweli Energy designed and delivered a 36 kWp off-grid solar power system integrated with 105 kWh of lithium-ion battery storage and a 20 kVA smart inverter.
The system generates and stores its own energy, supplying the campus independently of the grid. A standby generator is integrated for backup during extended low-generation periods.
System configuration:
- 36 kWp solar PV array
- 105 kWh lithium battery storage
- 20 kVA LV smart inverter system
- Integrated standby generator backup
- Wi-Fi remote monitoring
The system was sized to prioritise stable power for critical loads, particularly hospital operations.
What the System Powers
The off-grid system supports:
- Hospital operations and essential medical equipment
- School classrooms and offices
- Church and community facilities
- Orphanage and staff residences
- Water pumping and heating
- Kitchen and lighting loads
Measured Results
Since commissioning, the system delivers:
- Approximately 52 MWh of solar energy annually
- Around 99.9% reduction in power interruption impact
- Major reduction in generator running hours
- Approximately 40 tonnes of CO₂ reduction per year
The campus now operates primarily on solar energy, with significantly reduced diesel dependence.
Off-Grid Solar Power Systems in South Sudan
Kweli Energy designs and installs off-grid and hybrid solar systems for hospitals, schools, campuses and commercial facilities across South Sudan and East Africa.
Our systems are engineered for weak-grid and no-grid environments, where stability is critical and diesel costs are high.
If your institution requires a large-scale off-grid solar power system in Yei or elsewhere in South Sudan, our team can assess your energy needs and design a system suited to your operating conditions.
