Solar Irradiation Data in Curaçao

Curaçao benefits from high solar irradiation levels, making it an ideal location for solar energy projects.

Key Solar Irradiation Data:

Annual Solar Irradiation: Typically ranges from 5.5 to 6.0 kWh/m²/day
High Irradiation Regions: Most areas of the island, with southern and western parts receiving the highest levels of solar exposure
Peak Irradiation: Reaching 6.0–6.5 kWh/m²/day during the dry season (December to April)

Curaçao’s steady sunshine provides an excellent foundation for solar installations across both residential and commercial sectors.

Temperature Factors in Curaçao

Average Annual Temperature: Typically ranges from 24°C to 30°C (75°F to 86°F) year-round
Impact on Solar Panels: While high temperatures can lead to slightly reduced panel efficiency, Cuba’s consistent sunlight and cooling trade winds help mitigate performance losses

Recommendation: Use high-efficiency monocrystalline solar panels, optimized for tropical conditions and designed to handle the warm temperatures with better heat management.

Energy Demand and Grid Situation in Curaçao

National Energy Demand: Cuba’s energy demand is primarily driven by residential cooling, tourism, and agriculture
Electricity Supply: Historically, the country has relied on fossil fuels and hydropower for electricity generation, but solar energy is becoming a growing focus as part of the Cuban Government’s renewable energy plan
Electricity Costs: Cuba’s electricity costs are relatively low, but the government has begun promoting solar to reduce reliance on fossil fuels and improve energy security
Grid Infrastructure: The grid infrastructure is reliable in urban areas like Havana, but rural regions still face challenges with reliable electricity access, which makes solar systems a viable solution for improving resilience

Preferred System Type in Curaçao

Grid-Connected Systems: Ideal for urban areas and businesses like hotels, government offices, and commercial establishments
Off-Grid Systems: Suited for rural communities, eco-tourism sites, and agricultural operations where electricity access is limited
Hybrid Systems: Combining solar PV, battery storage, and backup generators is ideal for critical infrastructure, especially for use during periods of grid instability

Dust and Sand Factor in Curaçao

Dust Impact: Low to moderate dust levels due to frequent rainfall and oceanic proximity

Recommendation: Routine panel cleaning every few months should be sufficient, with increased cleaning after dry spells or tropical storms that can bring dust from nearby regions

Humidity and Rainfall (Humidity Factor) in Curaçao

Humidity Levels: High, particularly in the wet season (May to October), with humidity levels between 75% and 85%
Rainfall: The wet season brings heavy rainfall, especially along the coastal regions, though droughts can also occur
Impact on Solar Panels: The humidity and frequent rains can cause corrosion over time if systems are not adequately sealed

Recommendation: Use corrosion-resistant materials, weather-sealed connections, and IP-rated enclosures to ensure long-term durability.

Ocean (Salt Corrosion Factor) in Curaçao

Saltwater Corrosion: Being a coastal island, Cuba is exposed to salt-laden air, especially in coastal and beach areas

Recommendation: Use marine-grade materials for frames and stainless steel fasteners to combat the risk of corrosion due to salt exposure

Government Policies and Solar Incentives in Curaçao

Cuba has begun a push toward increasing renewable energy sources:

Renewable Energy Plan: The Cuban government has set a target to produce 24% of its energy from renewable sources by 2030, with solar energy playing a central role in this transition
Net Metering and Support: Incentives for small-scale solar systems and net metering programs are being implemented to encourage residential and commercial solar adoption
International Partnerships: Cuba has engaged in collaborations with international organizations like UNDP and the World Bank to promote renewable energy, including solar, and improve energy access for rural and off-grid communities

ROI on Solar Systems in Curaçao

ROI Period: Solar systems in Cuba typically achieve ROI within 5 to 7 years, driven by the country’s solar irradiance, incentive programs, and the financial savings from reducing reliance on fossil fuels
Long-Term Savings: Users can expect to save 50–75% on electricity bills, especially when adopting solar systems with battery storage for resilience during power interruptions

Conclusion on Solar Power in Curaçao

Cuba’s combination of strong solar irradiation, government-backed renewable energy policies, and growing energy needs make solar power a perfect solution for the island nation. As the country seeks to reduce its dependence on imported fuels and improve energy security, solar energy offers a pathway to sustainable growth.
