Solar PV Analysis of Klaukkala, Finland
Klaukkala, Uusimaa, Finland, situated in the Northern Temperate Zone, presents a challenging environment for year-round solar energy generation. The location's high latitude significantly impacts the effectiveness of solar photovoltaic (PV) systems throughout the year.
Seasonal Solar Energy Production
Solar energy production in Klaukkala varies dramatically across seasons. Summer offers the most favorable conditions, with an average daily output of 5.72 kWh per kW of installed solar capacity. Spring follows as the second-best season, producing 3.96 kWh/day. However, autumn and winter see a sharp decline in energy generation, with outputs of 1.40 kWh/day and a mere 0.50 kWh/day, respectively.
Optimal Times for Solar Generation
The ideal period for solar energy production in Klaukkala spans from late spring through early autumn. During these months, longer daylight hours and higher sun angles contribute to increased energy output. However, the effectiveness of solar PV systems diminishes significantly during the winter months due to shorter days and the sun's lower position in the sky.
Panel Installation Considerations
To maximize year-round solar energy production in Klaukkala, Uusimaa, fixed solar panels should be installed at a tilt angle of 50 degrees facing south. This angle is calculated to optimize energy capture throughout the year, considering the location's latitude and seasonal sun positions.
Environmental and Weather Factors
Several factors can impede solar production in Klaukkala:
- Snow accumulation during winter months can significantly reduce panel efficiency.
- Extended periods of overcast skies, common in autumn and winter, limit solar radiation reaching the panels.
To mitigate these issues, consider installing panels at a steeper angle to promote snow sliding off. Additionally, using high-efficiency panels and ensuring regular maintenance, including snow removal, can help maximize energy production even in challenging conditions.
Conclusion
While Klaukkala's location presents challenges for year-round solar energy production, proper system design and maintenance can still yield significant benefits, particularly during the summer months. The stark seasonal variations underscore the importance of complementary energy sources or storage solutions to ensure consistent power supply throughout the year.

Solar output per kW of installed solar PV by season in Klaukkala
Seasonal solar PV output for Latitude: 60.3942, Longitude: 24.7568 (Klaukkala, Finland), 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 Klaukkala, Finland
To maximize your solar PV system's energy output in Klaukkala, Finland (Lat/Long 60.3942, 24.7568) 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 Klaukkala, Finland
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 Klaukkala, Finland. 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 | 62° 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 Klaukkala, Finland
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 Klaukkala, Finland.
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 Klaukkala, Finland
Klaukkala, located in southern Finland, is situated in a region characterized by gently rolling terrain typical of the Finnish lowlands. The landscape around Klaukkala is a mix of forested areas, agricultural fields, and scattered settlements. The topography is generally mild, with subtle variations in elevation creating a softly undulating surface.
The area surrounding Klaukkala features low hills and shallow valleys, formed by ancient glacial activity. These gentle slopes are interspersed with flat areas, particularly near water bodies such as small lakes and streams. The highest points in the vicinity are typically only a few dozen meters above the surrounding terrain, creating a relatively uniform landscape.
Regarding large-scale solar PV installations, the most suitable areas near Klaukkala would be open, flat spaces with minimal shading from trees or buildings. Agricultural fields that are no longer in active use could be prime candidates for solar farms. South-facing slopes, even if gentle, would be particularly advantageous as they receive more direct sunlight throughout the day.
However, it's important to note that Finland's high latitude presents challenges for solar energy production. The region experiences long, dark winters with very little sunlight, which significantly reduces the efficiency of solar panels during these months. Conversely, the long summer days provide extended periods of sunlight, partially compensating for the winter deficit.
Ideal locations for large-scale solar PV near Klaukkala would be areas that combine the following characteristics:
- Large, open spaces with minimal tree cover
- Gently sloping or flat terrain, preferably with a southern aspect
- Proximity to existing electrical infrastructure for easy grid connection
- Areas not prone to flooding or excessive snow accumulation
- Locations that don't conflict with valuable agricultural land or protected natural habitats
While the mild topography around Klaukkala generally favors solar installations, careful site selection and environmental impact assessments would be crucial to ensure the most effective and sustainable use of the land for large-scale solar PV projects.
