Solar PV Analysis of Solna, Sweden
Situated in the Northern Temperate Zone, Solna, Stockholm County, Sweden (with coordinates 59.3591 latitude and 17.9948 longitude) presents a viable location for solar power generation, albeit with seasonal fluctuations inherent to its climatic conditions.
During the summer season, the average energy yield is approximately 5.84 kWh per day for each kW of installed solar capacity. This high output can be attributed to extended daylight hours and elevated temperatures that are conducive to optimal photovoltaic (PV) performance.
As autumn arrives, there is a noticeable decline in solar productivity due to shorter days and cooler weather conditions; an average of 1.58 kWh/day per kW of installed solar can be expected during this period.
The winter season presents further challenges with an even more significant drop in output down to an average of 0.57 kWh/day per kW of installed solar capacity due largely to cold temperatures and potential snowfall which can obstruct panels thereby reducing their efficiency.
With the advent of spring, however, there's a resurgence in energy production as longer daylight hours return along with milder weather; during this season one could anticipate generating around 4.11 kWh/day per kW from an installed PV system.
The ideal angle for fixed panel installation at this location is tilted towards South at a degree of approximately 49 degrees; this orientation maximizes exposure to sunlight throughout the year ensuring optimal energy generation from your PV system.
Despite these seasonal variations it’s worth noting that Solna's overall climate still allows for substantial annual power generation via solar PV systems when appropriately managed.
While no specific local environmental or topographical factors have been identified as significantly impeding on Solar production at this site, it’s important when installing panels here - or indeed anywhere - that consideration be given towards regular maintenance such as clearing snow or debris off panels during winter months which could otherwise restrict their 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 Solna
Seasonal solar PV output for Latitude: 59.3591, Longitude: 17.9948 (Solna, 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 Solna, Sweden
To maximize your solar PV system's energy output in Solna, Sweden (Lat/Long 59.3591, 17.9948) 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 Solna, 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 Solna, 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 Solna, 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 Solna, 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 Solna, Sweden
The topography around Solna, Sweden is mostly flat with some rolling hills and forested areas. The area is generally well-suited for large-scale solar PV installations due to its high levels of sunshine. Areas that are most suited for solar PV include flat rooftops, open fields, or cleared land near the city center. Additionally, there are several abandoned industrial sites in the area that could be repurposed for solar energy production.
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.
