Djursholm, Stockholm County, Sweden, located at latitude 59.4022 and longitude 18.0619, presents a challenging environment for year-round solar energy generation. This location in the Northern Temperate Zone experiences significant seasonal variations in solar output, which greatly impacts the effectiveness of solar PV systems.

Seasonal Solar Performance

The solar energy production in Djursholm varies dramatically across seasons. Summer months offer the most promising conditions, with an average daily output of 6.10 kWh per kW of installed solar capacity. Spring follows as the second-best season, generating 4.18 kWh/day. However, autumn and winter present significant challenges, with outputs dropping to 1.48 kWh/day and a mere 0.48 kWh/day, respectively.

Optimal Times for Solar Generation

The ideal period for solar energy production in Djursholm is from late spring through early autumn. During these months, longer daylight hours and higher sun angles contribute to increased solar panel efficiency. However, the effectiveness of solar PV systems is severely limited during the winter months due to shorter days and lower sun angles.

Panel Installation Considerations

To maximize year-round solar production at this location, fixed solar panels should be installed at a tilt angle of 49 degrees facing south. This angle is calculated to optimize the annual solar energy capture, taking into account the Earth's elliptical orbit and the specific latitude of Djursholm.

Environmental and Weather Factors

Several factors can impede solar production in Djursholm:

1. Long, dark winters: The high latitude results in extremely short days during winter, significantly reducing solar output.
2. Snow accumulation: Winter snowfall can cover panels, reducing efficiency.
3. Cloud cover: The region experiences frequent overcast conditions, particularly in autumn and winter.

Preventative Measures

To mitigate these challenges, consider the following measures when installing solar PV systems in Djursholm:

• Use high-efficiency panels designed for low-light conditions
• Install snow guards or heating elements to prevent snow accumulation
• Implement a robust cleaning and maintenance schedule
• Consider supplementary energy sources for winter months

While Djursholm's location presents significant challenges for year-round solar energy production, careful planning and appropriate technology can still make solar PV systems a viable part of the local energy mix, particularly during the more favorable months of the year.

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

Seasonal solar PV output for Latitude: 59.4022, Longitude: 18.0619 (Djursholm, Sweden), 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 49° South in Djursholm, Sweden

To maximize your solar PV system's energy output in Djursholm, Sweden (Lat/Long 59.4022, 18.0619) throughout the year, you should tilt your panels at an angle of 49° 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 Djursholm, Sweden

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 Djursholm, Sweden. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 49° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
42° South in Summer	61° South in Autumn	71° South in Winter	51° 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 Djursholm, Sweden

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 Djursholm, Sweden.

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 Djursholm, Sweden

The area surrounding Djursholm, Sweden, is characterized by a diverse and picturesque landscape typical of the Stockholm archipelago region. Located on a peninsula jutting into the Baltic Sea, Djursholm's topography is a mix of gently rolling hills, forested areas, and coastal lowlands. To the west and north of Djursholm, the terrain gradually rises, forming low hills and ridges. These areas are predominantly covered with mixed coniferous and deciduous forests, interspersed with clearings and small meadows. The highest points in this region reach elevations of around 30-40 meters above sea level, providing scenic views of the surrounding landscape and nearby water bodies. Towards the east and south, the land slopes gently towards the coastline, where it meets the waters of Stora Värtan, an inlet of the Baltic Sea. This coastal area features a combination of rocky outcrops, small beaches, and sheltered coves. The shoreline is irregular, with numerous small bays and inlets creating a complex and visually appealing coastal topography.

Potential for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors need to be taken into account. The ideal location would have ample open space, minimal shading, and good sun exposure throughout the year. Given the topography and land use patterns around Djursholm, the most suitable areas for large-scale solar PV would likely be found to the north and northwest of the town, where there are more extensive open areas and agricultural lands. These regions tend to have fewer trees and buildings that could cast shadows on solar panels, and the gently sloping terrain could provide optimal angles for solar exposure. However, it's important to note that the Stockholm region, including Djursholm, experiences relatively low levels of solar radiation compared to more southern latitudes. This factor, combined with the limited availability of large, undeveloped areas in this densely populated region, may present challenges for implementing truly large-scale solar PV projects. Smaller, distributed solar installations on rooftops and in smaller open spaces might be more feasible and common in this area.

Sweden solar PV Stats as a country

Sweden ranks 36th in the world for cumulative solar PV capacity, with 1,577 total MW's of solar PV installed. This means that 0.70% of Sweden's total energy as a country comes from solar PV (that's 39th in the world). Each year Sweden is generating 152 Watts from solar PV per capita (Sweden ranks 34th in the world for solar PV Watts generated per capita). [source]

Are there incentives for businesses to install solar in Sweden?

Yes, there are several incentives for businesses wanting to install solar energy in Sweden. The Swedish Energy Agency offers a number of grants and subsidies for businesses that want to invest in renewable energy sources such as solar power.
