sólarorka

Sólarorka is the Icelandic term for solar energy, referring to energy obtained from sunlight used to generate electricity or heat. The word combines sól (sun) and orka (energy or power).

Technologies used to capture sólarorka include photovoltaic (PV) systems that convert sunlight directly into electricity and solar thermal collectors that heat water or air for residential, commercial, or industrial use. Concentrating solar power (CSP) is uncommon in Iceland due to climate, land use, and scale considerations; hybrid systems and battery storage can improve reliability and seasonal performance.

In Iceland, electricity generation is dominated by hydro and geothermal sources, with sólarorka contributing a smaller share. Solar projects are typically small-scale, such as rooftop PV installations or solar water-heating systems. Output is highly seasonal, peaking during the extended daylight of summer and diminishing in winter, which influences deployment, economics, and the need for storage or backup.

Advantages of sólarorka include low operating costs, zero local emissions during use, and potential reductions in heating fuel needs, particularly in off-grid or new buildings. Challenges involve the variable and seasonally biased solar resource, the costs of equipment and installation, the need for storage or complementary energy sources, and regulatory or permitting requirements in some areas.

As part of Iceland’s broader renewable-energy strategy, sólarorka is viewed as a supplementary option to the country’s dominant hydro and geothermal resources, with potential for growth in rooftop installations, solar water heating, and decentralized energy solutions.
