The Role of Solar Power in Dominica’s Sustainable Development Goals

Country or Region Overview

Country or Region: Dominica

Capital: Roseau

Total Population: Approximately 72,000 (as of 2025)

Geographical Location: Dominica is an island nation in the Caribbean Sea, located between Guadeloupe to the north and Martinique to the south. Known as the "Nature Isle" for its lush rainforests, volcanic landscapes, and numerous waterfalls, Dominica also enjoys a tropical climate that is ideal for solar energy adoption.

Solar Irradiation Data in Dominica

Dominica benefits from high solar irradiation levels year-round, particularly in the drier months. Its tropical location offers great potential for both residential and commercial solar projects.

Key Solar Irradiation Data:

Annual Solar Irradiation: Typically ranges from 5.0 to 5.5 kWh/m²/day
High Irradiation Regions: The western and southern regions, particularly areas like Roseau, Portsmouth, and Morne Diablotin, which experience consistent sunlight
Peak Irradiation: Reaching 5.5–6.0 kWh/m²/day during the dry season (December to April)

The island’s consistent sunlight makes it ideal for solar energy production throughout the year.

Temperature Factors in Dominica

Average Annual Temperature: Ranges from 23°C to 29°C (73°F to 84°F)
Impact on Solar Panels: While warm temperatures can cause a minor reduction in efficiency, the steady sunlight hours ensure that solar panels in Dominica still operate efficiently

Recommendation: Use high-efficiency, temperature-resistant solar panels, and ensure ventilation around the panels to maximize performance in warm conditions.

Energy Demand and Grid Situation in Dominica

National Energy Demand: Dominica’s energy demand is driven by residential consumption, tourism, and agriculture
Electricity Source: Historically, the country has relied on diesel generators for power generation, but the government is pushing for renewable energy adoption to reduce reliance on imported fossil fuels
Electricity Costs: High electricity prices are encouraging both households and businesses to explore solar energy solutions
Grid Infrastructure: The grid in Roseau and other urban areas is reliable, but rural areas could benefit from more decentralized energy solutions like solar microgrids and battery storage

Preferred System Type in Dominica

Grid-Connected Systems: Best suited for urban homes, commercial properties, and tourism infrastructure in Roseau and Portsmouth
Off-Grid Systems: Ideal for remote communities, eco-lodges, and rural agricultural farms where grid access is limited
Hybrid Systems: Combining solar PV, battery storage, and backup generators is perfect for resorts, hospitals, and critical infrastructure that require uninterrupted power

Dust and Sand Factor in Dominica

Dust Impact: Minimal dust accumulation due to the island’s frequent rainfall and coastal air

Recommendation: Occasional cleaning during dry spells may be necessary, but overall, dust does not significantly affect system performance

Humidity and Rainfall (Humidity Factor) in Dominica

Humidity Levels: High, with average humidity between 70% and 85% year-round, particularly in the rainforests
Rainfall: Dominica experiences a wet season from June to November, with heavy rainfall during the hurricane season
Impact on Solar Panels: Moisture-related corrosion can be an issue if not properly addressed, and heavy rain can reduce panel efficiency during peak storm months

Recommendation: Use weather-sealed components and corrosion-resistant materials to prevent damage from high humidity and moisture

Ocean (Salt Corrosion Factor) in Dominica

Saltwater Corrosion: Being a coastal island, Dominica is exposed to salt-laden air that can corrode unprotected metal parts

Recommendation: Install marine-grade materials such as stainless steel fasteners, anodized aluminum frames, and corrosion-resistant wiring to ensure longevity in coastal environments

Government Policies and Solar Incentives in Dominica

Dominica is making strides toward a more sustainable energy future:

Renewable Energy Plan: The government has set a goal to produce 100% of its electricity from renewable sources by 2030, with solar energy playing a significant role in this transformation
Solar Incentives: Dominica offers tax incentives, import duty exemptions, and subsidies for solar energy projects to encourage adoption
International Partnerships: Dominica works with organizations like the Caribbean Development Bank (CDB) and the Green Climate Fund to promote renewable energy investments and improve energy access in rural areas

ROI on Solar Systems in Dominica

ROI Period: Solar systems in Dominica typically achieve ROI within 5 to 7 years, depending on system size, location, and available incentives
Savings Potential: Solar adopters can expect 50–70% savings on electricity bills, especially in commercial and tourism sectors that have higher energy demands

Conclusion on Solar Power in Dominica

Dominica’s combination of high solar irradiation, favorable government policies, and a growing need for sustainable energy makes solar power a perfect fit for the island.
