Solar PV Analysis of Arbon, Switzerland
Solar Energy Potential in Arbon, Thurgau, Switzerland
Arbon, Thurgau, Switzerland, situated at 47.5331°N, 9.4531°E in the Northern Temperate Zone, presents a mixed picture for solar energy generation. The location experiences significant seasonal variations in solar output, which affects its overall suitability for year-round solar power production.
During summer, Arbon enjoys its peak solar potential, with an impressive daily output of 5.71 kWh per kW of installed solar capacity. This makes it an excellent time for solar energy generation. Spring follows closely behind, with a respectable 4.85 kWh/day, offering good solar production opportunities.
However, the picture changes dramatically during the colder months. Autumn sees a considerable drop to 2.99 kWh/day, while winter plummets to a mere 1.52 kWh/day. This stark contrast highlights the challenges of maintaining consistent solar energy production throughout the year in Arbon.
Optimizing Solar Panel Installation
To maximize year-round solar energy production in Arbon, Thurgau, fixed solar panels should be installed at a tilt angle of 41 degrees facing south. This optimal angle takes into account the location's latitude and seasonal variations in sun position, ensuring the best possible energy capture across all seasons.
Environmental and Weather Considerations
Arbon's location presents some challenges for solar energy production. The region experiences frequent cloudy and overcast conditions, particularly during winter months. This can significantly reduce solar panel efficiency and overall energy output.
Additionally, Arbon's proximity to Lake Constance may lead to increased humidity and potential fog, further impacting solar radiation reaching the panels. Snowfall during winter months can also temporarily cover panels, reducing their effectiveness.
Mitigating Factors and Preventative Measures
To address these challenges, several preventative measures can be implemented:
- Install high-efficiency solar panels designed to perform well in low-light conditions
- Implement a robust cleaning and maintenance schedule to remove snow and debris
- Consider using solar trackers to maximize energy capture, especially during low-light periods
- Integrate energy storage solutions to balance out seasonal variations in production
While Arbon may not be ideal for year-round solar energy production, proper planning and implementation of these measures can significantly improve the viability and efficiency of solar PV systems in this location.
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 Arbon
Seasonal solar PV output for Latitude: 47.5331, Longitude: 9.4531 (Arbon, Switzerland), 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 41° South in Arbon, Switzerland
To maximize your solar PV system's energy output in Arbon, Switzerland (Lat/Long 47.5331, 9.4531) throughout the year, you should tilt your panels at an angle of 41° 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 Arbon, Switzerland
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 Arbon, Switzerland. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 41° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 31° South in Summer | 50° South in Autumn | 61° South in Winter | 40° 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 Arbon, Switzerland
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 Arbon, Switzerland.
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 Arbon, Switzerland
The area around Arbon, Switzerland, is characterized by a diverse and picturesque topography. Situated on the southern shore of Lake Constance (also known as Bodensee), Arbon enjoys a beautiful lakeside setting with gentle slopes rising from the water's edge. The immediate surroundings of the town are relatively flat, with a gradual incline as you move away from the lake.
As you travel south and southeast from Arbon, the landscape becomes more varied. Rolling hills and small valleys begin to appear, creating a patchwork of agricultural fields, orchards, and forested areas. These hills are part of the larger Swiss Plateau region, which stretches between the Alps and the Jura Mountains. The terrain in this area is generally mild, with elevations ranging from about 400 to 700 meters above sea level.
To the west and southwest of Arbon, the land remains relatively flat, with occasional gentle undulations. This area is part of the Thurgau canton, known for its fruit orchards and agricultural lands. The eastern side of Arbon transitions into the canton of St. Gallen, where the landscape gradually becomes more hilly as it approaches the Appenzell region.
Regarding areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, several factors need to be considered. The ideal locations would be:
- South-facing slopes: The gently rising terrain south of Arbon could offer good opportunities for solar farms, as these areas would receive more direct sunlight throughout the day.
- Open agricultural lands: The flat or mildly undulating farmlands in the Thurgau region to the west and southwest of Arbon could be suitable for ground-mounted solar arrays, provided they don't interfere with valuable agricultural production.
- Industrial areas: Existing industrial zones on the outskirts of Arbon and neighboring towns might be appropriate for rooftop solar installations or solar carports.
- Reclaimed land: Any unused or reclaimed land parcels that are not ecologically sensitive could be considered for solar development.
It's important to note that while the topography around Arbon is generally favorable for solar PV, other factors such as local regulations, grid connectivity, and environmental considerations would also play crucial roles in determining the most suitable locations for large-scale solar projects. Additionally, the region's climate, with its potential for fog and cloud cover from Lake Constance, would need to be carefully evaluated to ensure optimal solar energy production.
