Solar Energy Potential in Horsens, Central Jutland, Denmark

Horsens, Central Jutland, Denmark, located at 55.8572°N, 9.8606°E, presents a mixed picture for solar energy generation. Situated in the Northern Temperate Zone, this location experiences significant seasonal variations in solar output, which impacts the overall efficiency of photovoltaic (PV) systems throughout the year.

The summer months offer the most promising conditions for solar energy production, with an average daily output of 5.37 kWh per kW of installed solar capacity. This peak performance gradually declines as the year progresses, with autumn seeing a substantial drop to 1.79 kWh/day. Winter, as expected, presents the most challenging period, with production falling to a mere 0.80 kWh/day. However, spring brings a welcome resurgence, with output climbing back up to 4.11 kWh/day.

For those considering fixed panel installations in Horsens, Central Jutland, the optimal tilt angle for maximizing year-round solar production is 47 degrees facing south. This angle has been calculated to balance the varying solar elevation angles throughout the year, accounting for the Earth's elliptical orbit and local latitude.

Challenges and Considerations

While Horsens can certainly benefit from solar PV systems, there are several factors that may impede optimal energy production:

• Long, dark winters with limited daylight hours
• Frequent cloud cover and precipitation

To mitigate these challenges, several preventative measures can be taken during solar installation:

1. Use high-efficiency solar panels designed for low-light conditions to maximize output during overcast days and winter months.

2. Implement a robust cleaning and maintenance schedule to prevent snow accumulation and remove debris that may reduce panel efficiency.

3. Consider incorporating solar tracking systems to optimize panel orientation throughout the day and seasons, potentially increasing overall energy yield.

4. Explore the use of bifacial solar panels, which can capture reflected light from the ground, potentially boosting energy production, especially during snowy periods.

By addressing these factors and implementing appropriate solutions, solar energy systems in Horsens can still provide a valuable contribution to the local energy mix, particularly during the more productive spring and summer months.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Horsens

Seasonal solar PV output for Latitude: 55.8572, Longitude: 9.8606 (Horsens, 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 Horsens, Denmark

To maximize your solar PV system's energy output in Horsens, Denmark (Lat/Long 55.8572, 9.8606) 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 Horsens, 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 Horsens, 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 Horsens, 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 Horsens, Denmark.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Horsens, Denmark

The area surrounding Horsens, Denmark, located at approximately 55.8572°N latitude and 9.8606°E longitude, is characterized by a diverse and gently undulating landscape. This region, situated in eastern Jutland, features a mix of rolling hills, shallow valleys, and coastal plains that gradually slope towards the Horsens Fjord to the east. The topography of Horsens and its vicinity is largely shaped by glacial activity from the last ice age. As a result, the terrain is composed of low-lying areas interspersed with modest elevations, creating a patchwork of agricultural fields, forests, and scattered settlements. The highest points in the region typically reach no more than 100 meters above sea level, with many areas lying much closer to sea level, especially near the coast. To the west and northwest of Horsens, the landscape becomes slightly more elevated and hilly, with some areas featuring small forests and woodlands. These higher grounds gradually give way to the central Jutland ridge, which runs north-south through the peninsula. To the east and southeast, the terrain becomes flatter as it approaches the coastline and the Horsens Fjord, where low-lying meadows and wetlands are more common.

Suitable Areas for Large-scale Solar PV

When considering areas near Horsens that would be most suited for large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would combine favorable topography, minimal shading, and appropriate land use considerations. The gently sloping agricultural lands to the south and southwest of Horsens present promising opportunities for solar PV development. These areas often feature expansive, open fields with good sun exposure throughout the day. The slight inclination of the land in these regions can be advantageous for solar panel placement, potentially increasing their efficiency. Another suitable area for large-scale solar PV installations could be found in the more level terrain to the east of Horsens, approaching the coast. While care must be taken to avoid wetlands and environmentally sensitive areas near the fjord, the flat expanses in this region offer ample space and unobstructed sunlight for solar arrays. It's important to note that while the hilly areas to the west and northwest may seem appealing due to their elevation, they often feature more fragmented landscapes and forested patches, which could complicate large-scale solar development. However, some of the cleared hilltops in these areas might be suitable for smaller solar installations. When planning any large-scale solar PV project near Horsens, it would be crucial to consider local zoning regulations, environmental impact assessments, and the preservation of prime agricultural land. The relatively low-lying nature of the region also means that flood risk should be evaluated, particularly for areas closer to the coast or in valley bottoms.
