Situated in Sweden, Sollentuna is a location that offers considerable potential for solar photovoltaic (PV) power generation. The city experiences significant seasonal variations in solar energy production due to changes in daylight hours and weather conditions throughout the year. During the summer months, the average energy yield per kilowatt of installed solar capacity is at its peak, reaching 5.84 kWh per day. This high output can be attributed to extended daylight hours and increased sunlight intensity.
In contrast, autumn sees a reduction in solar energy production with an average of 1.58 kWh per day per kW of installed solar capacity. The decrease results from shorter days and less intense sunlight as Sollentuna transitions into colder seasons.
Winter presents the most challenging period for solar power generation, with an average yield dropping to 0.57 kWh per day per kW of installed capacity due to significantly reduced daylight hours and frequent overcast conditions.
However, spring brings a resurgence in solar productivity with an increase to 4.11 kWh/day/kW as daylight hours extend once more and sunlight intensity improves.
The optimal tilt angle for fixed-panel installations at this latitude is approximately 49 degrees facing southward; this orientation maximizes exposure to incoming sunlight throughout the year.
One environmental factor that could potentially impede solar production at this location includes heavy cloud cover or snowfall during winter months which can limit sun exposure on panels significantly reducing their efficiency during these periods.
To maximize productivity despite these challenges it's recommended that panels are regularly cleared of snow during winter months ensuring they receive maximum possible sunlight exposure even on shorter days while also preventing any potential damage caused by excessive weight or freezing temperatures.
Moreover, Sollentuna's generally mild climate characterized by occasional rain showers doesn't pose significant threats toward efficient operation but regular maintenance should still be carried out ensuring panels are clean from dust or other debris which may accumulate over time affecting their overall performance.
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 174 locations across Sweden. 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 Sollentuna
Seasonal solar PV output for Latitude: 59.4284, Longitude: 17.9653 (Sollentuna, 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 Sollentuna, Sweden
To maximize your solar PV system's energy output in Sollentuna, Sweden (Lat/Long 59.4284, 17.9653) 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 Sollentuna, 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 Sollentuna, 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 | 72° 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 Sollentuna, 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 Sollentuna, 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 Sollentuna, Sweden
The topography around Sollentuna, Sweden is generally flat with some low hills and valleys. Areas to the east of the city, near the E18 motorway, are particularly well-suited for large scale solar PV due to their flatness and abundance of open space. The area immediately south of Sollentuna is also suitable as it has fewer obstructions and even more open space than the eastern side.
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. Additionally, the government has implemented a feed-in tariff system which guarantees a fixed price for electricity generated from renewable sources such as solar. This helps to make investing in solar more attractive and financially viable for businesses.
