Solar PV Analysis of Aarhus, Denmark
Aarhus, Denmark (latitude: 56.162939, longitude: 10.203921) is a suitable location for generating solar power throughout the year, with varying levels of energy production across different seasons. In this region, the average daily energy output per kW of installed solar capacity is as follows: 5.77 kWh in Summer, 1.79 kWh in Autumn, 0.75 kWh in Winter, and 4.39 kWh in Spring.
The higher energy generation during the summer months can be attributed to Aarhus's position within the Northern Temperate Zone, which experiences longer daylight hours and increased temperatures during this time of year. These factors contribute to greater solar power generation potential compared to other seasons.
However, it is important to consider that weather conditions such as heavy rain or snowfall may impact solar power generation at this location due to reduced sunlight exposure and lower temperatures associated with these conditions. To mitigate these effects and ensure optimal energy production from solar installations in Aarhus, it is recommended that panels are installed at an angle of 47 degrees facing south.
This fixed panel installation will help maximize sunlight exposure throughout the year while minimizing potential losses caused by environmental factors like rain or snow accumulation on the panels' surface. Additionally, regular maintenance checks should be conducted to clear any debris or obstructions that could hinder sunlight absorption and overall system efficiency.
In conclusion, Aarhus offers a viable environment for generating solar power year-round despite seasonal fluctuations in energy production levels and occasional weather-related challenges. By implementing appropriate installation techniques and maintaining proper upkeep of solar systems at this location, it is possible to harness clean renewable energy effectively for both residential and commercial purposes.
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 130 locations across Denmark. 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 Aarhus
Seasonal solar PV output for Latitude: 56.162939, Longitude: 10.203921 (Aarhus, Denmark), 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 47° South in Aarhus, Denmark
To maximize your solar PV system's energy output in Aarhus, Denmark (Lat/Long 56.162939, 10.203921) throughout the year, you should tilt your panels at an angle of 47° 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 Aarhus, Denmark
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 Aarhus, Denmark. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 47° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 40° South in Summer | 58° South in Autumn | 69° South in Winter | 48° 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 Aarhus, Denmark
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 Aarhus, Denmark.
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 Aarhus, Denmark
The topography around Aarhus, Denmark is relatively flat with some gentle hills. Areas that would be most suited to large-scale solar PV installations are those that have open spaces with good access to sunlight and minimal shading from trees or other obstructions. Some potential sites include farmland and open fields in the surrounding area, as well as rooftops on buildings in the city centre.
Denmark solar PV Stats as a country
Denmark ranks 37th in the world for cumulative solar PV capacity, with 1,540 total MW's of solar PV installed. This means that 4.10% of Denmark's total energy as a country comes from solar PV (that's 19th in the world). Each year Denmark is generating 264 Watts from solar PV per capita (Denmark ranks 18th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Denmark?
Yes, there are several incentives for businesses wanting to install solar energy in Denmark. The Danish government offers a range of financial support and tax breaks for businesses that invest in renewable energy sources such as solar power. This includes grants, loans, and tax deductions. Additionally, the Danish Energy Agency provides subsidies for businesses that install solar panels on their premises. Finally, some local authorities offer additional incentives such as reduced electricity bills or free installation of solar panels.
