Solar PV Analysis of Ockelbo, Sweden
Ockelbo, Gävleborg County, Sweden, situated in the Northern Temperate Zone, presents a challenging location for year-round solar energy generation via photovoltaic (PV) systems. The seasonal variations in solar output at this location are significant, with substantial differences between summer and winter production.
Seasonal Solar Performance
Summer stands out as the most productive season for solar energy in Ockelbo, Gävleborg County, with an average daily output of 5.58 kWh per kW of installed solar capacity. Spring follows as the second-best season, yielding 3.96 kWh/day. However, autumn sees a sharp decline in production to 1.47 kWh/day, while winter experiences a dramatic drop to a mere 0.52 kWh/day per kW installed.
These figures indicate that solar energy generation in Ockelbo is highly seasonal, with the majority of production occurring during the longer, sunnier days of late spring and summer. The period from May to August is likely to be the most ideal for solar energy generation at this location.
Optimizing Solar Panel Installation
To maximize year-round solar energy production in Ockelbo, Gävleborg County, fixed solar panels should be installed at a tilt angle of 51 degrees facing south. This optimal angle helps to capture the most sunlight throughout the year, considering the location's latitude and seasonal sun paths.
Environmental and Weather Factors
Several factors can impede solar production in Ockelbo:
- Snow accumulation: Winter snowfall can cover panels, reducing efficiency. Regular snow removal or the installation of steep-angled panels can mitigate this issue.
- Limited daylight hours: During winter, Ockelbo experiences very short days, significantly reducing solar potential. While unavoidable, this emphasizes the importance of maximizing production during other seasons.
- Cloud cover: The region can experience extended periods of overcast weather, particularly in autumn and winter. Using high-efficiency panels and microinverters can help optimize performance in low-light conditions.
To enhance solar energy production in Ockelbo, Gävleborg County, consider implementing a dual-axis tracking system to follow the sun's path, although this comes with higher costs and maintenance requirements. Additionally, regular panel cleaning and the use of anti-reflective coatings can help maintain optimal performance throughout the year.
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 Ockelbo
Seasonal solar PV output for Latitude: 60.8887, Longitude: 16.7244 (Ockelbo, 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 51° South in Ockelbo, Sweden
To maximize your solar PV system's energy output in Ockelbo, Sweden (Lat/Long 60.8887, 16.7244) throughout the year, you should tilt your panels at an angle of 51° 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 Ockelbo, 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 Ockelbo, Sweden. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 51° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 44° South in Summer | 62° South in Autumn | 73° South in Winter | 53° 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 Ockelbo, 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 Ockelbo, 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 Ockelbo, Sweden
The area around Ockelbo, Sweden, is characterized by a diverse and picturesque landscape typical of central Sweden. Ockelbo is situated in the province of Gästrikland, which is known for its mixture of forests, lakes, and gently rolling terrain.
The topography of the region surrounding Ockelbo consists primarily of low-lying forested areas interspersed with numerous small lakes and streams. The terrain is generally flat to gently undulating, with occasional small hills and ridges. This landscape was largely shaped by glacial activity during the last ice age, resulting in a mix of glacial deposits, exposed bedrock, and water bodies.
To the north and west of Ockelbo, the land gradually rises towards the Scandinavian Mountains, though these higher elevations are still quite distant from the town itself. To the east and south, the terrain becomes slightly flatter as it approaches the coast of the Gulf of Bothnia, though this coastline is still some distance away from Ockelbo.
When considering areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, there are a few factors to consider. Ideally, solar farms require relatively flat, open areas with good exposure to sunlight throughout the day. Given the topography around Ockelbo, the most suitable locations would likely be:
- Cleared agricultural land to the south and southeast of Ockelbo, where the terrain is flatter and there are fewer obstructions from forests.
- Open areas on gentle south-facing slopes, which can be found scattered throughout the region, as these would receive more direct sunlight throughout the day.
- Former industrial or brownfield sites near the town, if any exist, as these often provide large, flat areas suitable for solar installations.
However, it's important to note that Sweden's high latitude means that solar energy potential is generally lower than in more southern countries. The long summer days can be advantageous, but the short winter days and frequent cloud cover pose challenges for solar energy production. Any large-scale solar PV project in this area would need to carefully consider these factors, as well as local environmental regulations and land-use policies.
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.
