Charting Guadeloupe’s Course to Solar Energy Leadership

Country or Region Overview

Country or Region: Guadeloupe

Capital: Basse-Terre

Total Population: Approximately 400,000 (as of 2025)

Geographical Location: Guadeloupe is an overseas region of France, located in the Caribbean Sea. The island consists of two main islands, Basse-Terre and Grande-Terre, along with several smaller islands. Guadeloupe enjoys a tropical climate, with consistent sunshine and distinct wet and dry seasons, making it an ideal location for solar energy development.

Solar Irradiation Data in Guadeloupe

Guadeloupe benefits from excellent solar irradiation year-round, with particularly strong solar potential during the dry season.

Key Solar Irradiation Data:

  • Annual Solar Irradiation: Typically ranges from 5.0 to 5.5 kWh/m²/day

  • High Irradiation Regions: Both Basse-Terre and Grande-Terre, with Grande-Terre receiving the most consistent sunlight

  • Peak Irradiation: Up to 5.5–6.0 kWh/m²/day during the dry season (December to April)

This provides an ideal environment for solar power generation, making solar energy a viable solution for residential, commercial, and industrial sectors.

Temperature Factors in Guadeloupe

  • Average Annual Temperature: Ranges from 24°C to 30°C (75°F to 86°F) year-round

  • Impact on Solar Panels: High temperatures are typical, but Guadeloupe’s consistent sunlight ensures that solar panels continue to perform efficiently throughout the year, especially with regular cooling from trade winds

Recommendation: Use high-efficiency monocrystalline panels that are optimized for tropical climates and designed to handle both high heat and consistent sunlight.

Energy Demand and Grid Situation in Guadeloupe

  • National Energy Demand: Guadeloupe’s energy demand is driven by residential cooling, tourism, and agriculture

  • Electricity Source: The island traditionally depends on fossil fuels and hydropower, but there is an increasing focus on solar energy to reduce reliance on imported fuels

  • Electricity Costs: Electricity rates are relatively high, which creates a strong economic incentive for solar energy adoption

  • Grid Infrastructure: The grid infrastructure in Basse-Terre and Grande-Terre is reliable, but the government is also encouraging solar microgrids and battery storage solutions for off-grid areas and emergency resilience

Preferred System Type in Guadeloupe

  • National Energy Demand: Guadeloupe’s energy demand is driven by residential cooling, tourism, and agriculture

  • Electricity Source: The island traditionally depends on fossil fuels and hydropower, but there is an increasing focus on solar energy to reduce reliance on imported fuels

  • Electricity Costs: Electricity rates are relatively high, which creates a strong economic incentive for solar energy adoption

  • Grid Infrastructure: The grid infrastructure in Basse-Terre and Grande-Terre is reliable, but the government is also encouraging solar microgrids and battery storage solutions for off-grid areas and emergency resilience

Dust and Sand Factor in Guadeloupe

  • Dust Impact: Minimal dust accumulation due to frequent rain and coastal location

Recommendation: Light cleaning after the dry season or heavy storms, but overall, dust is not a major issue for solar performance

Humidity and Rainfall (Humidity Factor) in Guadeloupe

  • Humidity Levels: High, with average humidity between 75% and 85%, particularly during the wet season (June to November)

  • Rainfall: Guadeloupe experiences a rainy season with heavy rainfall, especially in mountainous areas

  • Impact on Solar Panels: Humidity and rain can lead to moisture-related damage if not properly addressed, but overall, the systems perform well with proper protection

Recommendation: Use weatherproof and corrosion-resistant materials, and IP-rated enclosures to ensure longevity and performance despite the humidity.

Ocean (Salt Corrosion Factor) in Guadeloupe

  • Saltwater Corrosion: Guadeloupe is an island nation, and salt exposure is a concern, especially for installations close to the coast

Recommendation: Use marine-grade aluminum, stainless steel fasteners, and coated electronics to protect the system from saltwater corrosion in coastal areas

Government Policies and Solar Incentives in Guadeloupe

The government of Guadeloupe, as part of France’s renewable energy strategy, is promoting solar adoption:

  • Renewable Energy Policy: France, and by extension Guadeloupe, has set a target to achieve 40% renewable energy in its energy mix by 2030, with solar playing a significant role

  • Net Metering: Guadeloupe has a net metering program allowing residents and businesses with solar systems to export excess electricity to the grid, helping to offset costs

  • Tax Exemptions: Import duty exemptions and subsidies for solar systems make it easier to invest in solar energy

  • EU and French Government Support: Guadeloupe benefits from EU renewable energy incentives and French government programs aimed at increasing solar energy capacity in the region

ROI on Solar Systems in Guadeloupe

  • ROI Period: Solar systems in Guadeloupe typically achieve ROI within 5 to 7 years due to strong solar irradiance and available incentives

  • Savings Potential: Solar users can expect to save 50–70% on electricity bills, especially with the addition of battery storage to maximize self-consumption

Conclusion on Solar Power in Guadeloupe

Guadeloupe offers a tropical climate, abundant solar irradiation, and government support that makes it an excellent location for solar energy adoption. With the island’s strong push toward renewable energy, solar power presents a cost-effective, sustainable, and reliable solution for reducing electricity costs and enhancing energy independence.
