The location in Virum, Capital Region, Denmark, situated at coordinates 55.7935, 12.4693, presents a mixed picture for solar PV energy generation throughout the year. This Northern Temperate Zone location experiences significant seasonal variations in solar energy production, which impacts the overall efficiency of solar installations.

Seasonal Solar Performance

Solar energy production in Virum peaks during the summer months, with an impressive output of 5.78 kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season, generating 4.54 kWh/day. However, autumn sees a substantial drop to 1.90 kWh/day, while winter performance plummets to a mere 0.83 kWh/day per kW installed.

These figures highlight the stark contrast between summer and winter production, with summer yielding nearly seven times more energy than winter. This disparity is primarily due to the significant variation in daylight hours and sun angle between seasons at this latitude.

Optimal Panel Placement

To maximize year-round solar energy production in Virum, Capital Region, fixed solar panels should be tilted at a 47-degree angle facing south. This optimal angle takes into account the location's latitude and the sun's path throughout the year, balancing energy capture across all seasons.

Environmental and Weather Considerations

Several factors can impact solar production in Virum:

• Cloud cover: Denmark's climate is characterized by frequent overcast conditions, which can significantly reduce solar energy generation.
• Snow and ice: Winter accumulation on panels can obstruct sunlight and decrease efficiency.

To mitigate these issues, consider installing panels with anti-reflective coatings to improve performance in low-light conditions. Additionally, implementing a panel cleaning and maintenance schedule, particularly during winter, can help maximize energy production.

In conclusion, while Virum's location is not ideal for year-round solar energy production due to its northern latitude and climate, proper panel placement and maintenance can still yield significant energy output, especially during the extended daylight hours of summer and spring.

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 Virum

Seasonal solar PV output for Latitude: 55.7935, Longitude: 12.4693 (Virum, 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 Virum, Denmark

To maximize your solar PV system's energy output in Virum, Denmark (Lat/Long 55.7935, 12.4693) 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 Virum, 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 Virum, 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	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 Virum, 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 Virum, 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 Virum, Denmark

Virum, a suburb located in the municipality of Lyngby-Taarbæk, Denmark, is situated in a region characterized by gentle, rolling terrain. The topography around Virum is predominantly flat to slightly undulating, with occasional small hills and shallow valleys. This landscape is typical of the eastern part of Zealand, where glacial activity during the last ice age shaped the terrain. The area surrounding Virum features a mix of urban development, parklands, and scattered woodlands. To the east of Virum lies the picturesque Furesø, one of Denmark's deepest lakes, which contributes to the local topography with its shoreline and associated wetlands. To the west, the land gradually rises towards the town of Holte, creating subtle elevation changes in the landscape.

Potential 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 in much of the region surrounding Virum offers potential for solar farms, as it allows for easier installation and maintenance of solar panels. However, the urban nature of the area and the presence of protected natural spaces may limit available land for such projects. Areas to the south and southwest of Virum, towards Glostrup and Albertslund, might offer more suitable locations for large-scale solar PV installations. These areas have more open, agricultural land that could potentially be repurposed for solar energy production. The gently sloping terrain in these regions would provide good exposure to sunlight throughout the day, maximizing energy generation potential. It's important to note that while the topography around Virum is generally favorable for solar PV, other factors such as local zoning regulations, environmental considerations, and grid connectivity would also play crucial roles in determining the feasibility and location of any large-scale solar projects in the region.

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.
