Madagascar Embraces Solar as Key Energy Source
Country or Region Overview
Country or Region: Republic of Madagascar
Capital: Antananarivo
Total Population: Approximately 30 million (as of 2025)
Geographical Location: Madagascar is an island nation located in the Indian Ocean, off the southeast coast of Africa. It is the fourth-largest island in the world and lies east of Mozambique, across the Mozambique Channel. The country features varied topography, from humid rainforests in the east to dry plains and high plateaus in the central and western regions. With a largely rural population and limited electricity access, Madagascar offers strong potential for decentralized solar energy systems.

Solar Irradiation Data in Republic of Madagascar
Madagascar receives excellent solar irradiation, particularly in the central highlands, western dry regions, and southern zones. Even the eastern rainforest belt receives useful levels of solar energy.
Key Solar Irradiation Data:
-
Annual Solar Irradiation: Ranges from 4.5 to 6.0 kWh/m²/day
-
Sunshine Hours: Approximately 2,600 to 3,000 hours/year
-
Best Locations: Tuléar (Toliara), Morondava, Fianarantsoa, Ambositra, and central plateau areas
These conditions are ideal for off-grid systems, community mini-grids, residential rooftops, and agriculture-based solar solutions.

Temperature Factors in Republic of Madagascar
Madagascar has tropical to subtropical climate zones, depending on the region and elevation.
-
Coastal and lowland regions: Warm and humid, average temperatures between 24°C and 34°C
-
Highlands (Antananarivo, Fianarantsoa): Cooler, especially at night, with temperatures around 15°C to 28°C
Solar panels perform reliably year-round. For optimal performance:
-
Use ventilated, elevated racking systems
-
Ensure inverters and batteries are housed properly to handle both heat and occasional cold
-
Select high-efficiency modules suited for tropical environments
Energy Demand and Grid Situation in Republic of Madagascar
Electricity access in Madagascar is among the lowest in the world—with national access under 30%, and rural access below 10%. The grid, operated by JIRAMA, covers limited urban areas and is often unreliable due to aging infrastructure and fuel shortages.
Solar power offers the most feasible solution for electrifying remote communities, powering essential services, and improving energy reliability across the island.
Preferred System Type in Republic of Madagascar
Due to the country’s low electrification rate and rugged terrain, the following solar systems are well-suited to Madagascar:
-
Off-Grid Systems: Essential for rural households, schools, clinics, and agriculture
-
Mini-Grids: Effective for village-scale electrification where clustered demand exists
-
Hybrid Systems: Useful for NGO facilities, hotels, government services, and telecom towers
-
Grid-Tied Systems: Feasible in urban centers such as Antananarivo, Toamasina, and Mahajanga
Battery integration is essential in most regions due to limited or absent grid services.
Dust and Sand Factor in Republic of Madagascar
Dust is a moderate concern, particularly in the western dry zones, savanna areas, and during the dry season (May to October).
Maintenance tips:
-
Clean panels every 2–4 weeks in dusty regions
-
Use tilted installations for better rain-assisted cleaning
-
Consider dust-resistant modules or self-cleaning coatings for large systems
Eastern and central zones are less dusty due to higher humidity and rainfall.
Humidity and Rainfall (Humidity Factor) in Republic of Madagascar
Madagascar’s climate ranges from very humid in the east to semi-arid in the south and west.
-
Rainy season: Typically November to April, with heavy rains in the east and cyclone risk
-
Humidity: Up to 90% in eastern coastal zones
Protective measures include:
-
Use of IP66-rated inverters and enclosures
-
Installation of moisture-resistant cabling and sealed connectors
-
Elevated equipment bases to avoid flooding during heavy rain
Designing for tropical moisture is crucial, especially near the coast or in rainforest zones.
Ocean (Salt Corrosion Factor) in Republic of Madagascar
Salt corrosion is a significant concern in coastal areas, especially in Toamasina, Tuléar, Mahajanga, and Fort-Dauphin.
To mitigate corrosion:
-
Use marine-grade aluminum racking
-
Install stainless steel bolts and fasteners
-
Apply anti-corrosion coatings on metal and electrical enclosures
-
Plan regular maintenance in salty and humid areas
Inland highland regions are unaffected by salt exposure.
Government Policies and Solar Incentives in Republic of Madagascar
Madagascar is actively developing its renewable energy sector, with a focus on solar mini-grids and off-grid solutions to meet rural electrification targets.
Key initiatives include:
-
New Energy Policy (NEP) supporting renewable energy investment
-
Projects funded by World Bank, AfDB, UNDP, and USAID for rural mini-grids
-
National target to achieve 70% electricity access by 2030
-
Tax and duty exemptions on solar equipment under registered development programs
-
Government support for independent power producers (IPP) and public-private partnerships
The policy environment is improving, though more support for private investors is needed.
ROI on Solar Systems in Republic of Madagascar
With low access to electricity, expensive and unreliable fuel-based generation, and excellent solar resources, Madagascar offers a strong ROI for solar installations.
-
ROI Period:
-
Small off-grid systems: 2–4 years
-
Mini-grids and commercial hybrid systems: 4–6 years
-
-
Post-ROI Benefits: Long-term savings, reduced generator use, community development
-
Funding Access: Available through grants, donor funding, and impact investors
Solar is a cost-effective, life-changing investment for communities and institutions alike.
