Solar Energy Potential in Greenland
Country or Region Overview
Country or Region: Greenland (an autonomous territory of Denmark)
Capital: Nuuk
Total Population: Approximately 56,000 (as of 2025)
Geographical Location: Situated in the North Atlantic and Arctic Oceans, Greenland is the world’s largest island, located between North America and Europe. It lies northeast of Canada, with Iceland to its southeast, and is bordered by the Arctic Ocean to the north, the Greenland Sea to the east, and Baffin Bay and Davis Strait to the west. Its vast, icy interior is surrounded by rugged coastal fjords and mountains.

Solar Irradiation Data in Greenland (an autonomous territory of Denmark)
Greenland’s solar potential is limited by its high latitude and polar climate, with annual average solar irradiation ranging from 1.5 kWh/m²/day to 3.5 kWh/m²/day, heavily influenced by seasonal extremes. Summer months offer near-continuous daylight due to the midnight sun, particularly in southern regions like Qaqortoq and Nuuk, while winter brings prolonged darkness.
Key Solar Irradiation Data:
- Annual Solar Irradiation: 2.5 kWh/m²/day on average across populated coastal areas
- High Irradiation Regions: Southern coast (Nuuk, Qaqortoq), reaching 3.0 to 3.5 kWh/m²/day in summer
- Peak Irradiation: Up to 3.5 kWh/m²/day during June and July in the south
Though solar capacity remains small (under 1 MW by 2024), it is growing in coastal communities as a complement to diesel generators, driven by Denmark’s renewable energy goals and Greenland’s aim to reduce fossil fuel reliance in remote areas.

Temperature Factors in Greenland (an autonomous territory of Denmark)
- Average Annual Temperature: Greenland’s climate is predominantly Arctic, with average temperatures ranging from -10°C to 0°C (14°F to 32°F) along the coast and dropping to -30°C (-22°F) or lower inland. Summers in the south briefly reach 5°C to 15°C (41°F to 59°F), while winters plummet below -20°C (-4°F) across most regions.
- Impact on Solar Panels: Cold temperatures boost panel efficiency, but snow and ice accumulation can block sunlight, requiring careful design. Summer warmth has negligible impact due to low heat levels. Panels must endure extreme cold and wind.
- Recommendation: Solar systems should use cold-resistant, snow-shedding panels (e.g., monocrystalline with steep tilts) and robust inverters rated for subzero conditions. Anti-icing features and durable framing ensure performance in harsh Arctic weather.
Energy Demand and Grid Situation in Greenland (an autonomous territory of Denmark)
- National Energy Demand: Greenland’s energy needs are modest due to its small population, totaling around 50 GWh annually. Diesel generators dominate, supplying over 90% of electricity to scattered coastal settlements, supplemented by small hydropower in some areas. Solar is emerging as a viable alternative to reduce high fuel costs and emissions.
- Grid Infrastructure: Greenland lacks a centralized grid; each community operates independent microgrids, often diesel-powered. Solar integration is challenging due to isolation and seasonal sunlight variability, but pilot projects in Nuuk and Qaqortoq show promise, supported by battery storage. Denmark’s Arctic renewable strategy funds these efforts, targeting carbon neutrality by 2050.
- Opportunities from Global Events: Greenland’s role in international climate discussions (e.g., Arctic Council meetings) and potential tourism expos could highlight its renewable efforts, driving interest in solar-powered infrastructure for research stations and eco-tourism.
Preferred System Type in Greenland (an autonomous territory of Denmark)
- Grid-Connected Systems: Limited to larger towns like Nuuk and Sisimiut, where microgrids can incorporate solar with net metering potential. These systems reduce diesel use while maintaining reliability.
- Off-Grid Systems: Ideal for most of Greenland’s remote villages and research outposts, off-grid solar with battery storage provides sustainable power where diesel delivery is costly and logistically challenging.
- Hybrid Systems: For critical facilities like hospitals or larger settlements, hybrid systems combining solar with diesel or small wind turbines ensure 24/7 availability, especially during dark winter months.
Dust and Sand Factor in Greenland (an autonomous territory of Denmark)
- Dust and Sandstorms: Dust is not a significant concern in Greenland due to its icy, rocky terrain and minimal loose soil. Windblown snow or volcanic ash from Iceland (rare) poses a greater risk than dust.
- Recommendation: Basic maintenance to clear snow or debris suffices. Tilted panels help shed accumulation naturally, and dust-mitigation technologies are unnecessary given the climate.
Humidity and Rainfall (Humidity Factor) in Greenland (an autonomous territory of Denmark)
- Humidity Levels: Coastal Greenland has moderate humidity, averaging 60% to 80%, due to proximity to the ocean. Inland ice caps are drier, but sparsely populated. Precipitation (mostly snow) ranges from 300 to 800 mm/year, higher in the south.
- Impact on Solar Panels: Moderate humidity has little effect, though snow accumulation is the primary concern. Modern sealing prevents moisture issues, and rainfall is rare outside summer.
- Recommendation: Panels with robust encapsulation and snow-resistant designs suit coastal areas. Anti-reflective coatings enhance output during cloudy or snowy conditions.
Ocean (Salt Corrosion Factor) in Greenland (an autonomous territory of Denmark)
- Saltwater Corrosion: Greenland’s 44,000 km coastline exposes all populated areas to saltwater corrosion risks from sea spray and harsh winds. Inland ice is unaffected, but nearly all settlements are coastal.
- Recommendation: Solar systems must use marine-grade materials and anti-corrosion coatings. Regular cleaning removes salt deposits, ensuring durability in towns like Ilulissat or Tasiilaq.
Government Policies and Solar Incentives in Greenland (an autonomous territory of Denmark)
Greenland’s energy policies are influenced by Denmark’s renewable framework:
- Arctic Renewable Program: Denmark funds solar and hybrid projects to replace diesel in Greenland, targeting 70% renewable energy in public supply by 2030.
- Subsidies: Grants cover up to 50% of solar installation costs for communities, supported by the Greenlandic utility Nukissiorfiit.
- Carbon Reduction Goals: Aligns with Denmark’s net-zero by 2050 target, prioritizing solar in feasible regions.
These initiatives aim to lower energy costs (among the world’s highest) and reduce environmental impact in this fragile Arctic ecosystem.
ROI on Solar Systems in Greenland (an autonomous territory of Denmark)
- ROI Period: Solar ROI in Greenland ranges from 8 to 12 years, reflecting lower irradiation and high initial costs offset by diesel savings. Southern coastal areas achieve payback in 8 to 10 years, while northern regions take 10 to 12 years.
- Long-Term Savings: Over a 25-year lifespan, savings reach 40% to 60% compared to diesel, with greater returns in remote areas where fuel logistics are expensive.
Conclusion on Solar Power in Greenland (an autonomous territory of Denmark)
Greenland’s unique solar potential, though constrained by its Arctic climate, offers a sustainable complement to diesel in its coastal communities. With Denmark’s support and a focus on reducing carbon footprints, solar energy is a growing solution for this remote region.
