Comoros Goes with More Solar Solutions with Its Potential
Country or Region Overview
Country or Region: Comoros (Union of the Comoros)
Capital: Moroni
Total Population: Approximately 850,000 (as of 2025)
Geographical Location: Comoros is a small island nation located in the Indian Ocean, situated between Madagascar and the east coast of Mozambique. It consists of three main volcanic islands—Grande Comore (Ngazidja), Anjouan (Nzwani), and Mohéli (Mwali)—along with several smaller islets. Its tropical marine climate, high solar availability, and remote, dispersed geography make it an ideal candidate for solar energy expansion to improve national electrification and reduce fossil fuel reliance.

Solar Irradiation Data in Comoros (Union of the Comoros)
Comoros benefits from strong and stable solar radiation throughout the year, due to its proximity to the equator and minimal seasonal fluctuation.
Key Solar Irradiation Data:
-
Annual Solar Irradiation: Approximately 5.5 to 6.1 kWh/m²/day
-
Sunshine Hours: Around 3,000 hours per year
-
Peak Production Season: May to October (dry season)
These solar levels provide a solid foundation for decentralized energy systems, such as solar home systems, off-grid mini-grids, and solar water pumping solutions across all inhabited islands.

Temperature Factors in Comoros (Union of the Comoros)
Comoros experiences warm, tropical temperatures ranging from 24°C to 32°C throughout the year. The heat is moderated by ocean breezes, particularly along the coasts and in higher elevation areas.
To ensure long-term performance, solar systems should use high-temperature-tolerant panels with elevated and ventilated racking systems to reduce thermal losses and improve overall efficiency.
Energy Demand and Grid Situation in Comoros (Union of the Comoros)
Electricity access in Comoros is limited and unreliable. Only about 60–70% of the population has access to electricity, and most of it is concentrated in urban centers on Grande Comore. Power is primarily generated by diesel generators, which are costly and vulnerable to fuel price fluctuations and logistics.
Many rural areas and outer villages experience frequent blackouts or no grid access at all. As a result, solar power is widely recognized as a key solution to enhance energy security, especially for homes, health clinics, schools, and local businesses.
Preferred System Type in Comoros (Union of the Comoros)
Given Comoros’ island layout, fragmented grid coverage, and energy reliability issues, several system types are most effective:
-
Off-Grid Systems: Widely used for rural homes, clinics, and island communities without grid access
-
Mini-Grids: Ideal for clustered villages and community centers on Anjouan and Mohéli
-
Hybrid Systems: Increasingly used for hotels, urban businesses, and government buildings requiring backup during outages
-
Solar Water Pumps: Useful for agricultural projects and drinking water supply in remote areas
Battery storage is critical in most cases due to limited or unstable grid access.
Dust and Sand Factor in Comoros (Union of the Comoros)
Dust levels in Comoros are low to moderate, thanks to frequent rain and lush vegetation. However, areas near unpaved roads, dry inland zones, or during occasional dry spells can see some dust accumulation.
A cleaning interval of every 1 to 2 months is typically sufficient, and using a tilted panel installation helps natural rainfall assist in keeping panels clean.
Humidity and Rainfall (Humidity Factor) in Comoros (Union of the Comoros)
Comoros has a humid tropical climate, with relative humidity ranging from 70% to 90%, especially during the rainy season (November to April). Sudden tropical downpours and high humidity can affect unprotected equipment.
To ensure system durability, installers should use:
-
IP65+ rated inverters and charge controllers
-
UV- and moisture-resistant cables and connectors
-
Elevated enclosures for batteries and sensitive electronics
In flood-prone or coastal zones, waterproofing and drainage planning are essential.
Ocean (Salt Corrosion Factor) in Comoros (Union of the Comoros)
Given its island geography, most of Comoros’ solar systems are installed within a few kilometers of the coastline, making salt corrosion a high-risk factor.
To mitigate this:
-
Use marine-grade aluminum racking
-
Install stainless steel hardware
-
Apply anti-corrosion coatings on electrical boxes and connectors
-
Conduct biannual inspections for signs of salt buildup
Salt-resistant materials and designs are essential for all solar systems deployed across Comoros.
Government Policies and Solar Incentives in Comoros (Union of the Comoros)
The Comorian government has made clean energy expansion a national priority, supported by several international partners and donors. Key developments include:
-
Renewable Energy Policy (2015–2030) aiming for 100% renewable electricity coverage in rural areas
-
Ongoing projects supported by the World Bank, UNDP, and the African Development Bank
-
Plans to increase solar’s share in national electricity generation, with multiple donor-financed mini-grids under construction
-
Exemption from import duties for renewable energy systems (under approved projects)
While formal feed-in tariffs and net metering are not yet in place, community-scale pilot programs are showing early success.
ROI on Solar Systems in Comoros (Union of the Comoros)
With electricity tariffs ranging from USD 0.25 to 0.35/kWh, and frequent reliance on costly diesel generators, solar systems in Comoros offer a strong financial return—especially in remote and commercial applications.
-
ROI Period:
-
Off-grid residential systems: 2–4 years
-
Commercial or hybrid systems: 4–6 years
-
-
Savings: Significant reduction in generator fuel and maintenance costs
-
Non-Financial Benefits: Improved energy reliability, resilience during blackouts, and environmental sustainability
Solar’s role in powering education, healthcare, and community development adds long-term social and economic value.
Conclusion on Solar Power in Comoros (Union of the Comoros)
Comoros represents a high-potential solar market due to its strong sunlight, island-based energy needs, and growing demand for reliable power. With government backing, donor support, and public interest, solar is poised to become a pillar of Comoros’ energy future.
