Tungelsta, Stockholm County, Sweden, situated at 59.0995°N latitude and 18.0266°E longitude, presents a challenging environment for year-round solar PV energy generation. Located in the Northern Temperate Zone, this area experiences significant seasonal variations in daylight hours and solar intensity, which greatly impact solar energy production throughout the year.
Seasonal Solar Performance
Solar energy generation in Tungelsta varies dramatically across the seasons. Summer proves to be the most productive period, with an average daily output of 6.18 kWh per kW of installed solar capacity. Spring follows as the second-most productive season, yielding 4.26 kWh/day. However, autumn and winter see a sharp decline in solar energy production, with outputs of 1.54 kWh/day and a mere 0.51 kWh/day, respectively.
Optimal Times for Solar Generation
The ideal period for solar energy production in Tungelsta spans from late spring through early autumn. During these months, longer daylight hours and higher sun angles contribute to increased solar panel efficiency. The summer solstice, occurring around June 21st, marks the peak of solar potential in this region.
Panel Installation Considerations
For fixed panel installations in Tungelsta, Stockholm County, the optimal tilt angle to maximize year-round solar production is 48 degrees facing south. This angle helps to capture the most sunlight throughout the year, considering the location's latitude and seasonal sun path variations.
Environmental and Weather Factors
Several factors can impede solar production in Tungelsta:
- Long, dark winters: The region experiences very short days during winter, severely limiting solar energy generation.
- Snow accumulation: Winter snowfall can cover panels, reducing their efficiency.
- Cloud cover: Frequent overcast conditions, especially in autumn and winter, can significantly decrease solar output.
Preventative Measures
To mitigate these challenges and enhance solar energy production, consider the following measures:
- Install panels at the optimal 48-degree tilt to maximize exposure and encourage snow sliding off.
- Use high-efficiency panels designed for low-light conditions to improve performance during cloudy periods.
- Implement a regular cleaning and maintenance schedule, especially for snow removal in winter.
- Consider a dual-axis tracking system to follow the sun's path, potentially increasing energy yield, particularly during the longer summer days.
While Tungelsta's location presents challenges for year-round solar energy production, careful planning and appropriate technology can still make solar PV a viable renewable energy option, especially when combined with other energy sources to ensure consistent power supply throughout the year.

Ideally tilt fixed solar panels 48° South in Tungelsta, Sweden
To maximize your solar PV system's energy output in Tungelsta, Sweden (Lat/Long 59.0995, 18.0266) 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 Tungelsta, 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 Tungelsta, Sweden. 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 |
|---|---|---|---|
| 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 Tungelsta, Sweden

Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Tungelsta, Sweden
The area surrounding Tungelsta, Sweden, is characterized by a diverse and picturesque landscape typical of the Stockholm archipelago region. Located approximately 30 kilometers south of Stockholm, Tungelsta sits in a transitional zone between coastal lowlands and inland forested areas. The topography of the region is generally low-lying, with gentle undulations and occasional rocky outcrops. The terrain is a result of glacial activity during the last ice age, which sculpted the landscape and left behind numerous small lakes, ponds, and wetlands. These water features are interspersed throughout the area, creating a mosaic of land and water. Forests dominate much of the landscape around Tungelsta, consisting primarily of coniferous trees such as pine and spruce, with some deciduous species mixed in. These wooded areas are punctuated by clearings and open spaces, some of which are used for agriculture or pasture.
Potential for Solar PV Development
When considering areas nearby that might be suitable for large-scale solar PV installations, several factors come into play. The ideal locations would be relatively flat, open areas with good exposure to sunlight and minimal shading from trees or other obstacles. Some of the most promising areas for solar PV development near Tungelsta would likely be found in the agricultural lands to the south and southeast of the town. These areas tend to have larger open spaces with fewer trees, providing better solar access. Additionally, some of the cleared areas within the forested regions could potentially be utilized, though careful consideration would need to be given to the environmental impact of such developments. It's important to note that while Sweden's high latitude means it receives less solar radiation than more southerly countries, advances in solar technology have made PV installations increasingly viable in northern regions. The long summer days in Sweden can partially compensate for the shorter winter days, making solar energy a potentially valuable contributor to the local energy mix. Any large-scale solar PV project in the area would need to carefully balance energy production goals with environmental conservation and land use considerations. The unique ecosystem of the Stockholm archipelago region, with its mix of forests, wetlands, and agricultural areas, would require thoughtful planning to ensure sustainable development.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.
