Solar Energy Potential in Greve, Zealand, Denmark

Greve, Zealand, Denmark, situated at latitude 55.5804 and longitude 12.3, presents a mixed picture for solar energy generation throughout the year. Located in the Northern Temperate Zone, this area experiences significant seasonal variations in sunlight, which directly impacts solar PV performance.

Summer stands out as the most productive season, with an impressive daily output of 5.78 kWh per kW of installed solar capacity. Spring follows as the second-best season, generating 4.54 kWh per day. These months offer ideal conditions for solar energy production, with longer daylight hours and generally clearer skies.

However, the picture changes dramatically during the colder months. Autumn sees a significant drop in production to 1.90 kWh per day, while winter plummets to a mere 0.83 kWh daily output. This stark contrast highlights the challenges of relying solely on solar energy in this region year-round.

Optimizing Solar Panel Installation

To maximize year-round solar energy production in Greve, Zealand, it's crucial to install panels at the optimal angle. For fixed panel installations, the ideal tilt is 46 degrees facing south. This angle is calculated to capture the most sunlight throughout the year, considering the location's latitude and the Earth's elliptical orbit.

Environmental and Weather Factors

Several factors can impede solar production in Greve:

1. Cloud cover: Denmark's climate is characterized by frequent cloud cover, especially during autumn and winter, which significantly reduces solar irradiance.
2. Short winter days: The high latitude results in very short days during winter, severely limiting solar energy production.
3. Snow and ice: Winter precipitation can cover panels, reducing their efficiency.

To mitigate these challenges, consider the following preventative measures:

• Install panels at the optimal 46-degree angle to maximize exposure and encourage snow to slide off.
• Use high-efficiency panels designed for low-light conditions.
• Implement a regular cleaning schedule, especially during winter, to remove snow and debris.
• Consider a dual-axis tracking system to follow the sun's path, potentially increasing energy yield by up to 30%.

While Greve's location presents challenges for year-round solar energy production, proper installation techniques and maintenance can help maximize output during the more favorable months and mitigate losses during the less ideal periods.

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

Seasonal solar PV output for Latitude: 55.5804, Longitude: 12.3 (Greve, 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 46° South in Greve, Denmark

To maximize your solar PV system's energy output in Greve, Denmark (Lat/Long 55.5804, 12.3) throughout the year, you should tilt your panels at an angle of 46° 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 Greve, 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 Greve, Denmark. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 46° 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	57° South in Autumn	68° South in Winter	47° 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 Greve, 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 Greve, 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 Greve, Denmark

The area surrounding Greve, Denmark, located at approximately 55.5804°N latitude and 12.3°E longitude, is characterized by a relatively flat and low-lying topography typical of the eastern Danish landscape. This region, situated on the eastern coast of Zealand, the largest island in Denmark, features gently rolling plains with minimal elevation changes. The terrain around Greve is predominantly composed of fertile agricultural land, interspersed with small patches of forest and scattered settlements. The coastline to the east is marked by shallow waters and sandy beaches, while inland, the landscape transitions into a mix of cultivated fields, meadows, and occasional small hills.

Topographical Features

The most notable topographical features in the vicinity of Greve include the Køge Bay to the east, which forms part of the Baltic Sea. The coastline is relatively straight, with some minor indentations and small peninsulas. Inland, the landscape is crisscrossed by small streams and drainage channels, which are essential for managing water in this low-lying area. To the west and northwest of Greve, the terrain gradually rises, forming part of the modest hill country of central Zealand. However, even these elevations are modest by global standards, rarely exceeding 50 meters above sea level.

Suitability for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The relatively flat terrain around Greve offers advantages for solar farm development, as it minimizes the need for extensive land preparation and reduces shading issues between solar panels. The agricultural areas to the west and southwest of Greve present the most promising locations for large-scale solar PV projects. These open, unobstructed fields receive ample sunlight throughout the day and have fewer competing land uses compared to more densely populated areas closer to the coast. However, it's important to note that while the topography is favorable, the high latitude of Denmark means that solar irradiance is lower compared to more southerly regions. This factor, combined with the often cloudy Danish weather, may impact the overall efficiency of solar installations in the area. Developers would need to carefully balance the need for large, open spaces with the preservation of valuable agricultural land. Areas with poorer soil quality or those less suited for farming might be prioritized for solar development to minimize the impact on food production. In conclusion, while the topography around Greve is generally conducive to solar PV installations, careful site selection and environmental impact assessments would be necessary to identify the most suitable locations for large-scale projects in this predominantly agricultural and coastal region.
