Filipstad, Värmland County, Sweden presents some significant challenges for year-round solar energy generation, though it can be quite productive during certain seasons. This Northern Temperate Zone location experiences dramatic seasonal variations in solar output that make it less than ideal for consistent solar power production throughout the year.
Seasonal Solar Performance
The solar energy output at Filipstad varies dramatically across the seasons. Summer provides excellent solar generation at 5.58 kWh per day per installed kW, making it highly productive during these months. Spring offers reasonably good output at 3.97 kWh per day per kW, providing a solid shoulder season for energy production. However, the location faces significant challenges during the darker months. Autumn production drops substantially to just 1.45 kWh per day per kW, while winter output becomes extremely limited at only 0.53 kWh per day per kW. This winter figure represents less than one-tenth of the summer production capacity.Optimal Installation Configuration
For a fixed panel installation at Filipstad, Värmland County, the ideal angle to tilt solar panels is 50 degrees facing south to maximise total year-round production. This steeper angle helps capture the low winter sun more effectively while still performing well during the higher sun periods of summer.Environmental and Weather Challenges
Several significant local factors can impede solar production at this Swedish location:- Snow accumulation: Heavy winter snowfall can completely cover panels, blocking all solar production for extended periods
- Ice formation: Freezing conditions can create ice buildup on panel surfaces, reducing efficiency even when snow isn't present
- Limited winter daylight: The extreme northern latitude results in very short daylight hours during winter months
- Cloud cover: Frequent overcast conditions, particularly common in Nordic climates, can significantly reduce solar irradiance
Preventative Installation Measures
Several strategies can help maximise solar energy production despite these challenging conditions:- Steeper panel angles: Installing panels at angles steeper than the calculated 50-degree optimum can help snow slide off more easily
- Anti-icing systems: Installing heating elements or using special coatings can prevent ice buildup on panel surfaces
- Regular maintenance access: Designing installations with safe access for snow removal and cleaning during winter months
- Battery storage systems: Installing substantial battery capacity to store excess summer production for use during low-production winter periods
- Ground-mounted systems: These allow easier access for snow removal compared to roof-mounted installations
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Filipstad
Seasonal solar PV output for Latitude: 59.7109, Longitude: 14.1744 (Filipstad, 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 50° South in Filipstad, Sweden
To maximize your solar PV system's energy output in Filipstad, Sweden (Lat/Long 59.7109, 14.1744) throughout the year, you should tilt your panels at an angle of 50° 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 Filipstad, 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 Filipstad, Sweden. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 50° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 43° South in Summer | 61° South in Autumn | 72° South in Winter | 52° 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 Filipstad, 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 Filipstad, 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 Filipstad, Sweden
Topography Around Filipstad
Filipstad sits in the heart of Värmland County in central Sweden, positioned within a landscape that reflects the classic Scandinavian terrain of rolling hills, dense forests, and scattered lakes. The region forms part of the broader Swedish plateau, characterized by relatively gentle undulations rather than dramatic elevation changes. The town itself occupies a valley position, surrounded by forested hills that rise gradually from the settlement area.
The immediate vicinity features a mixed topography of low ridges and shallow valleys, with elevations typically ranging from around 100 to 300 meters above sea level. Dense coniferous forests dominate much of the landscape, primarily consisting of spruce and pine trees that are characteristic of the boreal forest zone. These woodland areas are interspersed with cleared agricultural land, small lakes, and wetland areas that add variety to the terrain.
The region's geology reflects its position on the Fennoscandian Shield, with underlying bedrock consisting mainly of ancient crystalline rocks including granite and gneiss. This solid geological foundation provides stable ground conditions, though the surface is often covered by glacial deposits left behind from the last ice age. These deposits create a gently rolling landscape with good drainage in many areas, though some locations retain seasonal moisture or support permanent wetlands.
Optimal Areas for Large-Scale Solar Development
The most suitable locations for large-scale solar photovoltaic installations around Filipstad would be the cleared agricultural areas and open fields that dot the landscape between the forested hills. These areas offer several advantages including existing cleared land that reduces development costs, relatively flat or gently sloping terrain that simplifies installation, and good accessibility via the region's network of rural roads.
South-facing slopes on the lower hills surrounding Filipstad present particularly attractive opportunities for solar development. These elevated positions benefit from reduced shading compared to valley locations, while the gentle gradients typical of the area make them suitable for large-scale installations without requiring extensive grading or terracing work.
Former industrial sites and brownfield locations near the town center could also prove valuable for solar development, as they often feature cleared land with existing infrastructure connections. The area's mining heritage has left several such sites that could be repurposed for renewable energy generation.
Areas to avoid would include the dense forest sections, which would require expensive clearing operations, and the numerous wetland areas scattered throughout the region. The low-lying areas near lakes and streams should also be avoided due to potential flooding risks and environmental sensitivities. The steeper slopes, while not extreme by mountain standards, would present installation challenges and potentially higher maintenance requirements for large-scale solar arrays.
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.
