Solar PV Analysis of Billund, Denmark
The location at Billund, South Denmark, Denmark has varying levels of effectiveness for generating energy via solar power throughout the year. In simpler terms, how much energy you can get from solar panels changes with the seasons.
During summer and spring, the amount of electricity that can be produced is quite high. Specifically, in summer you can expect around 5.44 kilowatt-hours (kWh) per day for each kilowatt (kW) of solar power installed. This decreases slightly in spring to about 4.18 kWh/day per kW installed.
However, during autumn and winter the production drops significantly due to shorter days and less sunlight. In autumn it goes down to about 1.85 kWh/day per kW installed and in winter it's even lower at just 0.84 kWh/day per kW installed.
For a fixed panel installation at this location, tilting your panels towards south at an angle of 47 degrees will give you maximum energy production all year round.
There are several local factors that could potentially affect solar production in Billund:
- Weather: Denmark tends to have a lot of cloud cover which could reduce the amount of sunlight hitting your panels.
- Seasonal changes: As mentioned earlier, there's a big difference between summer/spring and autumn/winter when it comes to potential energy generation.
- Environmental factors: Depending on where exactly your property is located there might be buildings or trees blocking some sunlight.
To ensure greater energy production despite these challenges:
- You might want to consider installing more advanced panels that work better under low light conditions.
- Regular maintenance like cleaning off snow or dirt from your panels would also help keep them working efficiently.
Overall while not ideal year-round due its geographical location and weather patterns; with proper planning and upkeep one can still make good use out of Solar PV systems in Billund, South Denmark, Denmark especially during Spring & Summer months when sunshine hours are higher compared to rest of the year.
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 Billund
Seasonal solar PV output for Latitude: 55.7298, Longitude: 9.1219 (Billund, 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 Billund, Denmark
To maximize your solar PV system's energy output in Billund, Denmark (Lat/Long 55.7298, 9.1219) 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 Billund, 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 Billund, 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 |
|---|---|---|---|
| 39° 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 Billund, 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 Billund, 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 Billund, Denmark
Billund, Denmark is located in the Jutland Peninsula and is characterized by a flat to gently rolling terrain. The region has an average elevation of around 50 meters above sea level. The landscape includes fields, forests, and small bodies of water.
For large-scale solar photovoltaic (PV) installations, flat or gently sloping areas are preferred as they require less work for installation and maintenance. Therefore, the vast open fields surrounding Billund could be suitable for such projects. However, it's important to remember that factors like sun exposure (solar irradiance), local weather patterns and land use restrictions also play significant roles in determining the suitability of a location for solar PV.
Denmark generally receives moderate amounts of sunlight throughout the year compared to more southern European countries due to its northern latitude position. However, with advancements in technology even regions with less optimal sunlight conditions can benefit from solar energy systems.
Areas towards south-facing slopes would potentially receive more sunlight than north-facing ones making them better suited for solar PV installations. Also places devoid of tall trees or buildings that could cast shadows on the panels would be ideal.
Before any large-scale project though, detailed site-specific assessments including environmental impact studies would need to be conducted.
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.
