Solar potential in Reykjavik
Reykjavik receives 2.26 kWh/m² per day on a horizontal surface, averaged over 30 years. Tilting panels to 36° raises annual output by 11%.
A typical home system is 5–10 kW. Roughly 15 panels for 6 kW.

Reykjavik sun and solar questions
- How much does daylight change through the year in Reykjavik?
- Reykjavik sits at 64.1° north. Its longest day runs 21h 09m and its shortest 4h 07m — a swing of 17h 02m.
- What angle should solar panels be in Reykjavik?
- 36° from horizontal, facing south, maximises annual production. That is about 11% more than laying panels flat. If you want to favour winter output, 75° is better; for summer, 19°.
- How much power would solar panels produce in Reykjavik?
- About 716 kWh per year for every kW installed, at the optimal angle. A typical 6 kW home system would produce roughly 4,298 kWh a year. Jun is the strongest month and Dec the weakest.
- How high does the sun get in Reykjavik?
- At the summer solstice the sun reaches 49.3° above the horizon at solar noon. At the winter solstice it only reaches 2.4°. That difference is what drives both the seasons and the ideal panel angle.
Sun times assume a flat horizon at sea level. Solar figures are long-term climate averages and do not account for shading, roof pitch or local regulations. See the methodology.
