Solar PV Analysis of Vejle, Denmark
In Vejle, South Denmark, Denmark, which is situated in the Northern Temperate Zone, the ability to generate energy from solar panels varies throughout the year. The amount of electricity produced by each kilowatt of installed solar power changes with each season.
During summer, a lot of energy can be generated as each kilowatt can produce 5.44kWh per day. This decreases to 1.85kWh/day in autumn and further drops to just 0.84kWh/day in winter when sunlight is limited due to shorter days and lower sun position. However, it increases again in spring where you can expect about 4.18 kWh/day for every kilowatt installed.
To get the most out of your solar panels all year round at this location, they should be tilted at an angle of 47 degrees facing South which will help capture as much sunlight as possible over different seasons.
However, there are some factors that might affect how much energy you can generate from your solar panels in Vejle due to its local weather conditions and environment.
Denmark generally has a lot of cloudy days which could reduce the amount of direct sunlight reaching your panels hence affecting their efficiency and output level especially during winter months when daylight hours are fewer compared to other seasons.
Also during winter months snowfall could cover up your solar panels blocking them from receiving any light at all thus disrupting electricity production significantly during these times.
As preventive measures against such issues:
- You could consider installing devices that automatically clear snow off your panel surfaces or manually do so yourself regularly.
- Also using high-quality PV modules designed for low-light performance would help maximize productivity on cloudy days.
- Regular maintenance checks would also ensure optimal functioning and longevity of your system overall ensuring greater energy production throughout various seasonal changes experienced here annually.
So while Vejle might not have consistent ideal conditions for generating solar power all year round like places closer to the equator, with the right setup and measures in place it can still be a viable option for sustainable energy production.
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 Vejle
Seasonal solar PV output for Latitude: 55.7019, Longitude: 9.5093 (Vejle, 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 Vejle, Denmark
To maximize your solar PV system's energy output in Vejle, Denmark (Lat/Long 55.7019, 9.5093) 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 Vejle, 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 Vejle, 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 Vejle, 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 Vejle, 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 Vejle, Denmark
Vejle, Denmark is located in the Jutland Peninsula and features a mix of topographical elements. The city itself is situated in a valley, surrounded by hills and forested areas. The landscape around Vejle includes rolling hills, forests, lakes, rivers and coastline along the eastern edge.
The region is known for its hilly terrain with heights reaching up to 100 meters above sea level which could potentially limit large-scale solar installations. However, there are also flat agricultural lands that could be suitable for such projects.
In terms of solar PV potential, it would largely depend on specific site characteristics such as slope orientation (south-facing slopes would be more suitable), vegetation cover (which can shade panels), soil conditions (for ground-mounted systems) and proximity to electrical grid connections.
However, considering Denmark's relatively high latitude and cloudy weather conditions compared to sunnier regions closer to the equator like Spain or Italy; the overall efficiency of solar power generation might not be as high here. Despite these factors though Denmark has been investing heavily into renewable energy including solar power so it's definitely feasible.
Specifically around Vejle some potential locations for large scale Solar PV installations might include flat farmlands near coastal areas where cloud cover may be less prevalent or on south-facing hill slopes that are clear from heavy vegetation or shadowing structures/buildings. It's also worth considering rooftops within urban areas for smaller scale distributed generation.
Nevertheless any proposed sites should undergo detailed technical feasibility studies which take into account all relevant factors including local climatic conditions (solar irradiance levels), land availability/use restrictions among others before deciding on their suitability for large-scale solar PV development.
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.
