Solar PV Analysis of Reykjanesbaer, Iceland
The location at Reykjanesbaer, Southern Peninsula, Iceland, is not ideal for year-round energy production through solar panels. This is because the amount of sunlight that this area receives varies greatly throughout the year. In summer, each kilowatt of installed solar can generate 4.37 kilowatt-hours per day, while in spring it can generate 3.67 kilowatt-hours per day. However, in autumn and winter, this drops to 1.05 and 0.31 kilowatt-hours per day respectively.
The best times to generate solar energy at this location are during the spring and summer seasons when there's more sunlight available due to longer daylight hours.
For a fixed panel installation at this location, tilting the panels at an angle of 53 degrees towards south would maximize their exposure to sunlight throughout the year and therefore increase their overall energy production.
There could be local factors that might affect solar production in Reykjanesbaer. For instance, Iceland’s weather is known for being unpredictable with frequent changes between sunny and cloudy conditions which could reduce the effectiveness of solar panels.
Moreover, its geographical location means it experiences long periods of darkness during winter months which would severely limit any potential for generating electricity from solar power during these times.
To mitigate these issues as much as possible when installing a photovoltaic system here:
1) Use high-quality PV modules that perform well even under less than ideal light conditions.
2) Implement tracking systems if feasible; these follow the sun’s path across sky maximizing exposure.
3) Regular maintenance should be performed on your PV system to ensure maximum efficiency.
4) Consider integrating your system with other renewable sources or storage solutions like batteries so you can store excess power produced during sunny periods for use when sun isn't shining or during winter months
Remember though: despite preventative measures taken against environmental factors affecting efficiency - given its geographical position - Reykjanesbaer may never provide optimal conditions for solar power generation year-round.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 19 locations across Iceland. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Reykjanesbaer
Seasonal solar PV output for Latitude: 63.9769, Longitude: -22.527 (Reykjanesbaer, Iceland), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
Ideally tilt fixed solar panels 53° South in Reykjanesbaer, Iceland
To maximize your solar PV system's energy output in Reykjanesbaer, Iceland (Lat/Long 63.9769, -22.527) throughout the year, you should tilt your panels at an angle of 53° South for fixed panel installations.
As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.
Seasonally adjusted solar panel tilt angles for Reykjanesbaer, Iceland
If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Reykjanesbaer, Iceland. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 53° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 47° South in Summer | 65° South in Autumn | 75° South in Winter | 54° South in Spring |
Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.
This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.
Calculate solar panel row spacing in Reykjanesbaer, Iceland
We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Reykjanesbaer, Iceland.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - Minimum Spacing:
We add the shadow length to the horizontal space occupied by tilted panels.
This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.
Topography for solar PV around Reykjanesbaer, Iceland
Reykjanesbaer, Iceland is located on the Reykjanes Peninsula. The topography of this area is characterized by a rugged landscape with volcanic and geothermal activity. The region features lava fields, hot springs, and geysers. It's also home to the Blue Lagoon, a popular geothermal spa.
Despite its northern location, Iceland does receive sunlight year-round - although the amount varies significantly between seasons due to its high latitude. During summer months (June-August), daylight can last up to 24 hours while in winter (December-February), daylight can be as short as 4-5 hours.
The areas most suited for large-scale solar PV installations would need to have relatively flat terrain for easy installation and maintenance of solar panels. However, given the volcanic nature of Reykjanesbaer's terrain which consists mostly of lava fields and mountains, finding such sites might be challenging.
Moreover, one must consider that despite having long daylight hours in summer months, Iceland’s weather is often cloudy which could limit solar radiation exposure necessary for efficient operation of solar panels.
Instead of focusing on solar energy alone given these challenges posed by topography and weather conditions; it may be more beneficial for this particular region to consider harnessing its abundant geothermal energy resources or wind energy potential.
