Solar Irradiation Data in Uruguay

Uruguay has good solar energy potential, with a stable and predictable solar resource across much of the country, especially in the north and interior regions.

Key Solar Irradiation Data:

Annual Solar Irradiation: Ranges from 4.0 to 5.0 kWh/m²/day
High Irradiation Regions: Northern departments like Tacuarembó, Rivera, and Artigas, and interior plains
Peak Irradiation: Up to 5.0–5.2 kWh/m²/day during the sunny months (October to March)

The combination of steady sunlight and strong government support makes Uruguay an excellent candidate for expanded solar deployment.

Temperature Factors in Uruguay

Average Annual Temperature: Mild subtropical climate, with temperatures ranging from 15°C to 22°C across the country
Impact on Solar Panels: Mild temperatures are highly favorable for solar panel efficiency, with minimal heat-related losses

Recommendation: Standard high-efficiency monocrystalline panels perform well, and tilted mounts help manage seasonal sun angles and rainfall runoff.

Energy Demand and Grid Situation in Uruguay

National Energy Demand: Uruguay has a small but growing energy demand, especially in the residential, industrial, and agricultural sectors
Grid Infrastructure: Uruguay boasts one of the most reliable and modern grids in South America, with nearly 100% electrification nationwide
Opportunities from Global Events: As a leader in renewables, Uruguay is focusing now on decarbonizing transportation and industries, creating new opportunities for distributed solar systems

Preferred System Type in Uruguay

Grid-Connected Systems: Ideal for urban and suburban areas, supporting residential, commercial, and industrial self-consumption
Off-Grid Systems: Useful for isolated farms, rural schools, or coastal facilities far from transmission lines
Hybrid Systems: Employed in agriculture, tourism, and industrial operations to provide backup during grid outages or to achieve energy independence

Dust and Sand Factor in Uruguay

Dust and Sandstorms: Minimal dust impact across most of Uruguay, as it is a green and agricultural country with frequent rains
Recommendation: Basic routine cleaning every few months is sufficient for optimal solar performance

Humidity and Rainfall (Humidity Factor) in Uruguay

Humidity Levels: Moderate to high, with annual humidity levels averaging 70–85%, especially near the coast
Impact on Solar Panels: High humidity can cause slow corrosion over time if systems are not properly protected
Recommendation: Use sealed modules, corrosion-resistant racking, and weatherproof cabling to ensure durability

Ocean (Salt Corrosion Factor) in Uruguay

Saltwater Corrosion: Coastal areas like Montevideo, Punta del Este, and Rocha face salt spray exposure
Recommendation: Install marine-grade mounting structures and anti-corrosion coatings for coastal solar projects

Government Policies and Solar Incentives in Uruguay

Uruguay is internationally recognized for its leadership in renewable energy:

National Energy Policy 2005–2030: Established long-term commitments to promote renewables, including solar
Net Metering: Available for residential and small commercial solar systems, allowing excess energy export to the grid
Investment Incentives: Solar equipment qualifies for import tax exemptions and accelerated depreciation benefits
Public Tenders: The government has auctioned utility-scale solar projects to diversify beyond hydro and wind

ROI on Solar Systems in Uruguay

ROI Period: Solar installations in Uruguay typically pay back within 6 to 8 years, with faster returns for larger commercial systems
Long-Term Savings: Solar adopters can save 50–75% on electricity costs across the system’s lifetime, depending on consumption patterns and incentives

Conclusion on Solar Power in Uruguay

Uruguay’s energy success story is well-known — a small country that turned ambitious policy into real renewable achievements. Now, as the focus shifts toward a more diversified and distributed energy future, solar power is poised to play an even bigger role. Beyond simply keeping the lights on, solar can help Uruguay drive electric mobility, power smart farms, and strengthen community resilience.

The opportunity is clear: solar offers a way for homes, businesses, and farms across Uruguay to not only cut costs but to become active participants in the country’s energy leadership. Solarvance stands ready to support Uruguay’s next energy chapter with high-efficiency, durable solar solutions adapted for both its fertile inland regions and its coastal towns.
