The location of Gram, South Denmark, Denmark, situated at latitude 55.285 and longitude 9.0276, presents a mixed picture for solar PV energy generation throughout the year. Located in the Northern Temperate Zone, this area experiences significant seasonal variations in solar output.

Seasonal Solar Performance

Summer stands out as the most productive season, with an impressive daily output of 5.37 kWh per kW of installed solar capacity. Spring follows as the second-best season, generating 4.11 kWh per day. However, the performance drops considerably during autumn, with only 1.79 kWh per day, and reaches its lowest point in winter, producing a mere 0.80 kWh daily.

These figures highlight the stark contrast between the bright, long days of summer and the short, often overcast days of winter in this northern European location. The substantial difference in output between seasons suggests that solar energy generation in Gram is highly dependent on the time of year.

Optimal Panel Installation

To maximize year-round solar production at this location, fixed solar panels should be installed at a tilt angle of 46 degrees facing south. This angle is calculated to capture the most sunlight across all seasons, taking into account the Earth's elliptical orbit and the site's specific latitude.

Environmental and Weather Factors

Several factors could potentially impede solar production in Gram:

1. Cloud cover: Denmark's climate is characterized by frequent cloudy days, especially in autumn and winter, which can significantly reduce solar output.
2. Short winter days: The high latitude results in very short days during winter months, limiting the time available for solar energy generation.
3. Snow and frost: Winter conditions may lead to snow accumulation or frost on panels, further reducing efficiency.

Preventative Measures

To mitigate these challenges and ensure greater energy production, consider the following measures when installing solar PV systems in Gram:

• Use high-efficiency panels designed for low-light conditions to maximize output on cloudy days.
• Install panels at the optimal 46-degree angle to capture maximum sunlight year-round.
• Implement an automated cleaning system or regular maintenance schedule to remove snow and frost from panels during winter.
• Consider incorporating energy storage solutions to balance the seasonal variations in solar output.

While Gram's location presents challenges for year-round solar energy production, proper system design and maintenance can help maximize the potential of solar PV technology in this northern European setting.

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 Gram

Seasonal solar PV output for Latitude: 55.285, Longitude: 9.0276 (Gram, 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 Gram, Denmark

To maximize your solar PV system's energy output in Gram, Denmark (Lat/Long 55.285, 9.0276) 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 Gram, 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 Gram, 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 Gram, 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 Gram, 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 Gram, Denmark

The topography around Gram, Denmark, located at latitude 55.285 and longitude 9.0276, is characterized by a gently rolling landscape typical of southern Jutland. This area is part of the Danish glacial plains, shaped by the retreat of ice sheets during the last ice age. The terrain consists of low hills, shallow valleys, and scattered small forests interspersed with agricultural fields. The region surrounding Gram is relatively flat, with only minor variations in elevation. Most of the land lies between 20 to 50 meters above sea level, creating a subtle undulating effect across the countryside. Small streams and brooks meander through the area, contributing to the gentle contours of the land.

Suitability for Large-Scale Solar PV

When considering areas nearby that would be most suited for large-scale solar photovoltaic (PV) installations, several factors come into play. The relatively flat terrain in the vicinity of Gram offers advantages for solar energy development. Open agricultural fields, which are abundant in this region, provide ideal locations for solar farms due to their expansive, unobstructed spaces. Areas to the south and west of Gram would likely be the most suitable for large-scale solar PV projects. These directions generally receive more direct sunlight throughout the day, maximizing the potential energy generation. Additionally, the absence of significant geographical features that could cast shadows or obstruct sunlight makes these areas particularly attractive for solar installations. It's important to note that while the topography is favorable, other factors such as local zoning regulations, grid connectivity, and environmental considerations would also need to be taken into account when planning large-scale solar projects in this area. The proximity to existing infrastructure and power lines would play a crucial role in determining the most cost-effective locations for solar farms. Overall, the gentle, open landscape around Gram provides a good foundation for solar energy development, with ample opportunities for large-scale installations on the available agricultural lands, particularly those lying to the south and west of the town.
