Iceland Could Benefit from Solar PV for Land Use and Cost Optimization

When you picture Iceland’s energy landscape, you likely think of the powerful forces of geothermal vents and glacial rivers. The nation is a world leader in renewable energy, powered almost entirely by hydro and geothermal sources. But what about the sun? It might seem counterintuitive for a country known for its long, dark winters, but a growing body of evidence suggests that solar photovoltaic (PV) technology holds significant, untapped potential for the Land of Fire and Ice.

Solar PV could play a key role in helping Iceland optimize its land use and further reduce energy costs, even in such an unexpected location. Let’s explore how.

Discovering the Surprising Efficiency of Solar and Iceland solar PV benefits

A common misconception is that solar panels thrive on heat. In reality, excessive heat can reduce their efficiency. Cold, sunny conditions, however, are ideal for PV technology. The cooler temperatures in northern latitudes like Iceland’s actually boost the efficiency of solar modules and slow their natural degradation over time.

According to a report from the IEA Photovoltaic Power Systems Programme (IEA PVPS), the Greater Arctic region (defined as areas above 60°N latitude) has vast untapped potential for solar energy. As of 2023, the installed capacity in this region was estimated at around 1,400 MWp. The report highlights that even with lower solar irradiation, the cold climate creates a favorable environment for effective energy production. This makes the case for solar in Iceland much stronger than one might initially assume.

Optimizing Land Use with Iceland solar PV benefits

Iceland’s stunning and often rugged terrain demands careful consideration for any new development. One of the most compelling arguments for solar PV is its efficiency in terms of land use. Compared to other low-carbon options like bioenergy, solar power can generate significant energy from a relatively small footprint.

This advantage allows for strategic deployment in areas that are already developed, such as on rooftops of industrial and residential buildings, or on land that is otherwise unsuitable for agriculture. By minimizing the demand for new land, solar PV can be integrated into the landscape without disrupting Iceland’s pristine natural environment. This strategic approach to land use is crucial for sustainable development.

A Cost-Effective Complement Exploring Iceland solar PV benefits

While Iceland already boasts a robust renewable energy grid, solar power offers a valuable opportunity for cost optimization and diversification. The global cost of solar PV technology has plummeted in recent years, making it an increasingly affordable option.

Solar power’s generation profile is also a perfect complement to Iceland’s existing energy sources. Solar panels produce the most electricity during the long daylight hours of summer, which coincides with the peak tourist season and its associated energy demands. By adding solar to the mix, Iceland can reduce the strain on its hydro and geothermal resources during these peak periods.

Furthermore, integrating solar with wind power and battery storage systems can create resilient microgrids. These systems can enhance energy security and provide a stable power supply for remote communities, reducing their reliance on a centralized grid and improving overall grid stability.

Adapting Solar Technology for the Arctic Environment and Iceland solar PV benefits

Of course, deploying solar technology in a sub-arctic climate comes with unique challenges, from heavy snowfall to frost. However, modern solar technology has evolved to meet these demands. Key adaptations for a market like Iceland include:

• Bifacial Modules: These panels can capture sunlight on both sides, taking advantage of light reflected off snow-covered ground to significantly boost energy production.
• Vertical or Steep-Tilt Arrays: Mounting panels at a steep angle or even vertically helps them shed snow easily, minimizing downtime during winter months.
• Durable Infrastructure: Specially designed layouts and frost-proof foundations are essential to ensure the long-term durability and performance of solar installations in harsh conditions.

By leveraging these technological advancements, Iceland can effectively overcome the environmental hurdles and harness its solar potential. The path forward involves supportive policies, incentives for rooftop installations, and a clear vision for integrating solar power as a third pillar in the nation’s celebrated renewable energy strategy.
