Solar Energy Potential in Hirtshals, North Denmark, Denmark

Hirtshals, North Denmark, located in northern Denmark at coordinates 57.5912, 9.9496, presents a challenging environment for year-round solar energy generation. The town's position in the Northern Temperate Zone significantly impacts its solar potential, with stark seasonal variations in energy output. During summer, solar panels in Hirtshals can produce a respectable 5.86 kWh per day for each kilowatt of installed capacity. This output drops dramatically in autumn to 1.65 kWh/day and plummets to a mere 0.60 kWh/day in winter. Spring sees a recovery, with production rising to 4.46 kWh/day. These figures highlight that solar energy generation in Hirtshals is most effective from late spring through early autumn. The long summer days in this northern latitude contribute to the higher output during this period. However, the short, dark winter days severely limit solar production, making it an unreliable energy source during colder months.

Optimal Panel Installation

To maximize year-round solar energy production in Hirtshals, North Denmark, fixed solar panels should be installed at a tilt angle of 48 degrees facing south. This angle is calculated to capture the most sunlight throughout the year, considering the town's latitude and the Earth's elliptical orbit.

Environmental and Weather Factors

Several environmental and weather factors can impede solar production in Hirtshals: 1. Frequent cloud cover: The coastal location experiences significant cloud cover throughout the year, reducing solar irradiance. 2. High humidity: Proximity to the sea results in high humidity, which can decrease panel efficiency. 3. Salt spray: Being close to the ocean exposes panels to salt spray, potentially causing corrosion and reducing efficiency over time. To mitigate these factors, several preventative measures can be taken:

• Use high-quality, corrosion-resistant solar panels designed for coastal environments.
• Install a robust cleaning system to regularly remove salt deposits and other debris.
• Implement a slightly steeper tilt angle to promote natural cleaning by rainwater.
• Consider using bifacial solar panels to capture reflected light on cloudy days.

While these measures can help improve solar energy production in Hirtshals, North Denmark, it's important to note that the location's seasonal variations and weather patterns make it challenging for consistent year-round solar energy generation. Complementary renewable energy sources or energy storage solutions should be considered to ensure a stable energy supply throughout the year.

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 Hirtshals

Seasonal solar PV output for Latitude: 57.5912, Longitude: 9.9496 (Hirtshals, 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 48° South in Hirtshals, Denmark

To maximize your solar PV system's energy output in Hirtshals, Denmark (Lat/Long 57.5912, 9.9496) throughout the year, you should tilt your panels at an angle of 48° 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 Hirtshals, 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 Hirtshals, Denmark. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 48° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
41° South in Summer	59° South in Autumn	70° South in Winter	50° 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 Hirtshals, 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 Hirtshals, 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 Hirtshals, Denmark

The topography around Hirtshals, Denmark, is characterized by a mix of coastal and inland features. Located on the northern tip of the Jutland peninsula, Hirtshals is situated where the Skagerrak meets the North Sea. The immediate coastal area is dominated by sandy beaches and low-lying dunes, which gradually give way to gently rolling hills as one moves inland. The terrain surrounding Hirtshals is relatively flat, with only slight variations in elevation. This area is part of the larger North Jutlandic Island region, which is known for its expansive plains and open landscapes. The coastline near Hirtshals features dramatic cliffs in some areas, particularly to the east, while the western coast is more gradual and sandy. Inland from Hirtshals, the landscape transitions into agricultural fields and scattered woodlands. Small streams and wetlands dot the countryside, creating a diverse ecosystem. The soil in this region is generally sandy and less fertile compared to other parts of Denmark, which has influenced land use patterns over time.

Suitability for Large-Scale Solar PV

When considering areas near Hirtshals for large-scale solar photovoltaic (PV) installations, several factors come into play. The most suitable locations would be inland, away from the immediate coastal area, where there is less environmental sensitivity and more available land. The gently rolling hills and open fields to the south and southeast of Hirtshals present promising opportunities for solar PV development. These areas benefit from relatively flat terrain, which simplifies installation and reduces shading issues. The agricultural nature of much of this land also means there are large, uninterrupted spaces that could potentially be repurposed or dual-used for solar energy production. However, it's important to note that Denmark's high latitude means that solar irradiance is lower compared to more southern regions. This factor, combined with the country's frequently overcast weather, may impact the overall efficiency of solar PV systems. Despite these challenges, advancements in solar technology have made it increasingly viable even in northern climates. Any large-scale solar PV project would need to carefully consider local zoning regulations, environmental impact assessments, and the integration with existing power infrastructure. The areas to the south of Hirtshals, where the landscape opens up into wider plains, might offer the best balance of available land, minimal topographical obstacles, and proximity to existing electrical grid connections.
