Solar PV Analysis of Eskilstuna, Sweden
Eskilstuna, Södermanland County, Sweden, which is located in the Northern Temperate Zone, has varying potential for solar energy production throughout the year. The amount of energy that can be generated from a kilowatt (kW) of installed solar power varies by season.
During the summer months, you can expect to generate approximately 5.84 kilowatt-hours (kWh) per day for each kW of installed solar power. This means that summer is an excellent time for generating solar energy in Eskilstuna because there's plenty of sunlight.
In autumn and spring, the expected daily output drops to 1.58 kWh and 4.11 kWh per day respectively for each kW of installed solar power. So while these seasons are not as productive as summer, they still offer decent opportunities for harnessing solar energy.
Winter sees a significant drop in potential output to just 0.57 kWh per day per kW due to shorter daylight hours and lower sun angles.
To get the most out of your solar panels year-round at this location, it's recommended that they be tilted at an angle of 49 degrees facing southward.
As with any location, there may be local factors that could affect how much sunlight your panels receive and thus their efficiency in generating electricity.
For instance:
- Weather: In Eskilstuna like many parts of Sweden it can snow heavily during winter months which could cover up your panels reducing their efficiency.
- Topography: If there are tall trees or buildings around that cast shadows on your panels during certain times of the day or year this will also reduce their efficiency.
To mitigate these issues:
- Regularly clear off any snow from your panels during winter.
- Ensure your installation site is clear from shadow-casting obstructions where possible when installing them.
By taking these measures into account when installing your system you'll help ensure greater overall energy production from it over time regardless of seasonal changes or local environmental factors.
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 Eskilstuna
Seasonal solar PV output for Latitude: 59.369, Longitude: 16.5053 (Eskilstuna, 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 Eskilstuna, Sweden
To maximize your solar PV system's energy output in Eskilstuna, Sweden (Lat/Long 59.369, 16.5053) 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 Eskilstuna, 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 Eskilstuna, 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 Eskilstuna, 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 Eskilstuna, 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 Eskilstuna, Sweden
Eskilstuna, Sweden is located in the Södermanland County and is characterized by a mixed topography of flat plains and rolling hills. The landscape around Eskilstuna includes forests, agricultural fields, rivers and some small lakes.
For large-scale solar PV installations, flat or gently sloping areas are typically preferred as they require less site preparation and can accommodate more panels per unit area. Therefore, the agricultural fields around Eskilstuna could be suitable for such installations.
However, it's important to note that Sweden has relatively low solar insolation compared to sunnier countries closer to the equator. This means that while it's technically possible to generate solar power in this region, the efficiency (and therefore economic viability) of such a project might be lower than in other regions.
It would also be crucial to consider local regulations and zoning laws when planning for large-scale solar projects. Some areas may have restrictions on land use which could limit where a solar farm can be built.
Lastly, proximity to existing power grids should also be considered for ease of connecting the generated electricity into the grid. Areas closer to Eskilstuna city or other populated areas with established infrastructure might therefore be more suited for large-scale PV projects from this perspective.
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.
