Solar Irradiation Data in Anguilla

Anguilla benefits from excellent solar irradiation levels year-round, making it an ideal location for solar energy systems.

Key Solar Irradiation Data:

Annual Solar Irradiation: Ranges from 5.5 to 6.5 kWh/m²/day
Consistent Year-Round Sun: Sunlight levels are high and steady throughout the year, with minimal seasonal variation
High Potential: One of the strongest solar profiles among island nations in the Caribbean

This makes Anguilla highly suitable for residential and commercial solar PV systems, including off-grid and hybrid setups.

Temperature Factors in Anguilla

Average Annual Temperature: Ranges from 26°C to 30°C (79°F to 86°F)
Impact on Solar Panels: While solar panel efficiency can drop slightly in high heat, Anguilla’s strong sunlight more than compensates for this

Recommendation: Use panels designed for tropical climates, with excellent thermal management and ventilation, and position them to maximize exposure while minimizing overheating.

Energy Demand and Grid Situation in Anguilla

National Energy Demand: The island has a relatively small but growing energy demand, mainly for residential cooling, hospitality, and public infrastructure
Grid Infrastructure: Electricity is supplied by the Anguilla Electricity Company (ANGLEC), with diesel generators as the main source
Rising Costs: The cost of electricity is among the highest in the Caribbean, increasing interest in solar as a cost-saving alternative

Preferred System Type in Anguilla

Grid-Tied Systems with Battery Backup: Ideal for homes and businesses, allowing users to reduce reliance on diesel-generated electricity and ensure power during outages
Off-Grid Systems: Suited for remote villas, beachfront properties, and areas where extending the grid is costly
Hybrid Systems: Excellent for hotels, restaurants, and public facilities, combining solar, batteries, and backup generators for resilient energy supply

Dust and Sand Factor in Anguilla

Dust Impact: Generally low, though occasional Saharan dust events can slightly reduce solar performance
Recommendation: Schedule routine cleaning every few months, especially during dust seasons, to maintain efficiency

Humidity and Rainfall (Humidity Factor) in Anguilla

Humidity Levels: High, averaging 75–85%
Rainfall: Moderate to heavy during the hurricane season (June to November)
Impact on Panels: High humidity can affect connectors, frames, and mounts if not properly protected

Recommendation: Use marine-grade components, anti-corrosion coatings, and IP-rated waterproof enclosures

Ocean (Salt Corrosion Factor) in Anguilla

Salt Exposure: Very high, as the island is completely surrounded by ocean
Corrosion Risk: Salt-laden air accelerates corrosion of metal parts and wiring

Recommendation: Install systems using stainless steel or anodized aluminum frames, UV-stable and salt-resistant wiring, and sealed junction boxes designed for coastal use

Government Policies and Solar Incentives in Anguilla

Government Strategy: Anguilla has stated its commitment to renewable energy, with targets to reduce fossil fuel dependency
Regulatory Framework: Still under development, but pilot projects and microgrid support are emerging
Support from International Agencies: Projects supported by organizations such as CARICOM and the Caribbean Development Bank (CDB)

While direct incentives are limited, the economic incentive from high energy prices makes solar financially attractive even without subsidies.

ROI on Solar Systems in Anguilla

ROI Period: Typically between 4 to 6 years, thanks to high irradiation and expensive diesel-based electricity
Long-Term Savings: Homeowners and businesses can cut electricity costs by 60–80% with solar installations, depending on the system size and storage capacity

Conclusion on Solar Power in Anguilla

In sun-drenched Anguilla, the transition to solar power is not just smart—it’s essential. With some of the Caribbean’s highest solar irradiation levels and some of the highest energy costs, switching to solar offers clear economic and environmental advantages. Though humidity and salt air present engineering challenges, modern solar technologies have proven to be reliable and long-lasting under these conditions.
