Solar Energy Lights Up Congo the Democratic
Country or Region Overview
Country or Region: Democratic Republic of the Congo (DRC)
Capital: Kinshasa
Total Population: Approximately 105 million (as of 2025)
Geographical Location: The Democratic Republic of the Congo is located in Central Sub-Saharan Africa, bordered by nine countries: the Republic of the Congo, Central African Republic, South Sudan, Uganda, Rwanda, Burundi, Tanzania (across Lake Tanganyika), Zambia, and Angola. It is the second-largest country in Africa by area and is rich in natural resources, but energy access remains a major challenge, especially in rural areas. The DRC lies along the equator and features dense rainforest, savannah, mountain regions, and river basins—making solar energy one of the few viable solutions for decentralized electrification.

Solar Irradiation Data in Democratic Republic of the Congo (DRC)
Despite its equatorial rainforests, the DRC receives strong solar irradiation, particularly in the southern, eastern, and northern regions where skies are clearer and cloud cover is lower.
Key Solar Irradiation Data:
-
Annual Solar Irradiation: Varies between 4.5 and 5.8 kWh/m²/day
-
Sunshine Hours: Between 2,500 to 3,000 hours per year, depending on region
-
Best Regions: Katanga, Kasaï, North Kivu, Haut-Lomami, and parts of Tshopo
With its vast land area and energy-deficient regions, solar offers a transformative solution for lighting, healthcare, education, and agriculture across the DRC.

Temperature Factors in Democratic Republic of the Congo (DRC)
The DRC experiences tropical climate patterns, with average temperatures ranging from 23°C to 34°C. The climate is:
-
Hot and humid in the north and central rainforest belt
-
Warm and dry in southern provinces such as Haut-Katanga and Lualaba
-
Mild and temperate in elevated eastern regions like Goma and Bukavu
Proper solar system performance can be maintained through:
-
Low-temperature coefficient PV modules
-
Elevated and ventilated mounting designs
-
Components rated for high-heat, high-humidity environments
Energy Demand and Grid Situation in Democratic Republic of the Congo (DRC)
The DRC has one of the lowest electricity access rates globally, with only about 19% of the population connected to the national grid. In rural areas, this drops below 5%. Even in urban centers, the grid is unstable, with frequent blackouts and voltage fluctuations.
Electricity generation is dominated by hydropower, but poor transmission infrastructure and conflict have left most of the population relying on kerosene, charcoal, or diesel generators. Solar is widely regarded as the most scalable and practical solution for electrification across the country’s vast and underserved territories.
Preferred System Type in Democratic Republic of the Congo (DRC)
Due to diverse terrain, infrastructure challenges, and vast off-grid populations, the following system types are ideal for DRC:
-
Off-Grid Systems: For rural homes, clinics, schools, and farms
-
Mini-Grids: Suited for village clusters, markets, and health districts
-
Hybrid Systems: Useful for mission hospitals, NGOs, and commercial operations needing grid or generator backup
-
Solar Home Systems (SHS): Scalable and affordable for individual households across remote provinces
Battery storage is crucial in all cases to ensure night-time use and continuity during cloudy days or grid failure.
Dust and Sand Factor in Democratic Republic of the Congo (DRC)
Dust conditions vary by region:
-
Southern provinces (Katanga, Kasai): Moderate to high dust, especially during the dry season
-
Rainforest belt (Équateur, Tshuapa, Mai-Ndombe): Low dust, thanks to frequent rainfall and vegetation
Systems in dusty areas should be cleaned every 2–4 weeks, while rainforest regions may need only monthly maintenance. Tilted mounts help reduce accumulation.
Humidity and Rainfall (Humidity Factor) in Democratic Republic of the Congo (DRC)
The DRC experiences high humidity and substantial rainfall, particularly in the central and western zones. Rainfall can exceed 1,500 to 2,000 mm/year in areas like Equateur and Ituri, with relative humidity often above 85%.
To ensure system longevity:
-
Use IP66-rated enclosures
-
Opt for sealed connectors and insulated cabling
-
Install components in well-ventilated, protected areas
-
Raise batteries and control units above ground level
Solar installations must be carefully waterproofed to prevent corrosion and electrical hazards.
Ocean (Salt Corrosion Factor) in Democratic Republic of the Congo (DRC)
Although the DRC has a narrow Atlantic Ocean coastline at Banana Port, most of the country is inland, and salt corrosion is not a major factor for the vast majority of solar systems.
Only systems installed near the coastal zones of Kongo Central province may require corrosion-resistant components, such as:
-
Marine-grade aluminum racking
-
Stainless steel bolts and brackets
-
Salt-proof coatings on external electronics
Government Policies and Solar Incentives in Democratic Republic of the Congo (DRC)
The DRC’s government is increasingly promoting renewable energy as part of its electrification strategy, with solar playing a key role in rural access:
-
National Electrification Strategy (2022) promotes off-grid and mini-grid solar expansion
-
Import tax exemptions for solar components under certain public-private partnerships
-
Support from World Bank, EU, and AfDB for rural energy access programs
-
Donor-led projects implementing solar schools, solar health posts, and off-grid village electrification
Although there is no feed-in tariff yet, the government is working to improve the legal and investment climate for independent power producers (IPPs).
ROI on Solar Systems in Democratic Republic of the Congo (DRC)
With limited access to grid electricity and widespread use of costly fuels, solar provides strong ROI and life-enhancing impact, especially in humanitarian and rural settings.
-
ROI Period:
-
Small systems: 1–3 years (due to high kerosene and generator replacement savings)
-
Commercial/hybrid systems: 3–5 years, depending on scale and usage
-
-
Post-ROI Benefits: Long-term operational savings, business productivity, and reduced emissions
-
Funding Access: Grants, microfinance, and development funds support affordability for low-income users
Solar can bring immediate improvements to health, education, and livelihoods in areas where no alternatives exist.
Conclusion on Solar Power in Democratic Republic of the Congo (DRC)
The Democratic Republic of the Congo offers enormous potential for solar energy, both in terms of scale and social impact. With abundant sunshine, low electrification, and strong donor support, solar is essential to closing the energy access gap and supporting sustainable development.
