The Role of Solar Energy in Turks and Caicos Islands’ Climate Action Plan
Country or Region Overview
Country or Region: Turks and Caicos Islands
Capital: Cockburn Town (on Grand Turk Island)
Total Population: Approximately 45,000 (as of 2025)
Geographical Location: The Turks and Caicos Islands are located in the southeastern Bahamas chain, in the northern Caribbean, east of Cuba and north of the Dominican Republic and Haiti. As a British Overseas Territory, the country is made up of 40 low-lying coral islands, with only 8 inhabited. It is known for its luxury resorts, clear blue waters, and a sun-rich tropical climate—favorable for solar power systems.

Solar Irradiation Data in Turks and Caicos Islands
The islands receive very high solar irradiation, with relatively little seasonal variation due to their position close to the Tropic of Cancer. This consistent sunlight allows for highly efficient solar energy production year-round.
Key Solar Irradiation Data:
-
Annual Solar Irradiation: Between 5.5 and 6.2 kWh/m²/day
-
Sunshine Hours: Over 3,000 hours per year
-
Best Months: January through May, though solar production is stable year-round
These solar conditions provide a strong base for both residential and commercial solar installations, especially where grid electricity is expensive or limited.

Temperature Factors in Turks and Caicos Islands
Turks and Caicos experiences average annual temperatures ranging from 26°C to 33°C. The climate is hot and sunny, particularly during the dry season, which runs from November to May.
While high ambient temperatures can slightly reduce solar panel efficiency, this is mitigated through proper ventilation, spacing, and the use of high-efficiency panels designed for hot climates.
Energy Demand and Grid Situation in Turks and Caicos Islands
Electricity in the Turks and Caicos Islands is provided primarily by FortisTCI, a private utility company operating across the major islands. Power generation is still largely based on diesel fuel, making electricity expensive and carbon-intensive.
Electricity demand is driven by the tourism industry, luxury housing, and commercial sectors, especially on Providenciales and Grand Turk. Grid access is reliable in developed areas but limited on smaller or outer islands, where off-grid solar systems are essential.
Preferred System Type in Turks and Caicos Islands
Due to high utility prices and strong sun exposure, solar systems are increasingly seen as both a cost-saving and sustainable energy solution.
-
Grid-Connected Systems: Suitable for urban homes, resorts, and businesses
-
Hybrid Systems: Recommended for critical infrastructure, villas, and hotels that require power during outages
-
Off-Grid Systems: Ideal for remote homes, smaller cays, and undeveloped areas with no utility connection
Battery integration is becoming more common as a solution for nighttime use and energy reliability.
Dust and Sand Factor in Turks and Caicos Islands
Dust levels in the Turks and Caicos Islands are generally low, due to frequent ocean breezes and a relatively clean environment. However, during the dry season, some airborne dust and debris may settle on panels, especially in construction zones.
A simple cleaning routine every 1–2 months is typically enough to maintain strong energy yields.
Humidity and Rainfall (Humidity Factor) in Turks and Caicos Islands
Humidity is moderate to high, typically ranging from 70% to 85%, with a rainy season that lasts from May to October. Rainfall is sporadic but can be intense during tropical weather systems.
To ensure durability, all systems should use:
-
Weather-sealed (IP65+) enclosures
-
Moisture-resistant wiring and connectors
-
Corrosion-resistant racking and hardware
Proper mounting and drainage are essential to reduce risk from pooling or prolonged damp conditions.
Ocean (Salt Corrosion Factor) in Turks and Caicos Islands
With most of the country’s buildings located close to the ocean, salt-laden air presents a significant corrosion risk to solar systems. This is especially critical in coastal zones and elevated rooftops exposed to sea spray.
Solar equipment in Turks and Caicos should include:
-
Marine-grade aluminum or anodized steel mounting structures
-
Stainless steel bolts and fasteners
-
Anti-corrosion coated junction boxes and enclosures
Routine inspection and basic cleaning help prolong system life in these high-salt environments.
Government Policies and Solar Incentives in Turks and Caicos Islands
The government of the Turks and Caicos Islands has signaled a commitment to increasing renewable energy adoption, although the regulatory framework is still evolving.
Key highlights include:
-
Net billing options through FortisTCI’s CORE program, allowing customers to offset usage
-
No import duties on renewable energy components under specific conditions
-
Government collaboration with international partners on sustainability and energy resilience programs
-
Ongoing feasibility studies for utility-scale solar and microgrid integration
Incentives may not yet be comprehensive, but there is growing public and private interest in renewable energy solutions.
ROI on Solar Systems in Turks and Caicos Islands
With electricity prices ranging from USD 0.34 to 0.44 per kWh, solar systems in the Turks and Caicos Islands offer very favorable ROI.
-
ROI Period: Typically 4 to 6 years, depending on system size and usage
-
Post-ROI Benefits: Long-term electricity savings, protection from price hikes, and improved energy reliability
-
Value to Property: Solar increases property marketability and supports sustainable tourism branding
Systems with storage become even more attractive for high-end properties and resorts seeking energy independence.
