Evaluating Solar Energy in Reykjavik, Iceland
Solar Overview
The photovoltaic potential in Reykjavik is based on 1,414 annual sun hours, concentrated in May. This northern location at 64.15° latitude results in highly variable solar production, with extended summer days balanced by dark winters. Solar installations in Reykjavik require thoughtful design and may benefit from energy storage to optimize the limited available solar resource.
Geographic Impact
Located at 64.1466° latitude and -21.9426° longitude, Reykjavik's geographical position significantly impacts its solar potential. The very high latitude results in extreme sun angle variation, with summer angles reaching moderate heights but winter angles barely above the horizon, requiring specialized mounting solutions.
Rating Methodology
Reykjavik receives a "Poor" rating for solar potential, derived from comprehensive analysis of 1,414 annual sun hours, 4.9°C average temperature, and geographic factors. Extreme cold benefits photovoltaic output, particularly when combined with reflective snow cover that increases total irradiation on panels. Reykjavik's conditions enable systems to generate 900-1,100 kWh per installed kW annually, supporting partial energy independence.
Understanding the Data
The visualization below presents the annual cycle of sun hours in Reykjavik. Summer months deliver 48% of the year's solar resource, dramatically exceeding winter's 12% contribution. This seasonal pattern is typical for locations at this latitude and influences the sizing and economics of solar installations.
⚠️ Important: Due to the high seasonal concentration of solar production, battery storage systems are particularly valuable in Reykjavik to balance energy availability throughout the year.
❄️ Advice: Consider bifacial panels to capture reflected light from snow cover, potentially boosting production by 10-20% in winter.
