Solar PV Analysis of Rickenbach Bei Wil, Switzerland
Rickenbach bei Wil, Switzerland, located in the Northern Temperate Zone, presents a mixed picture for solar energy generation through photovoltaic (PV) panels. This location experiences significant seasonal variations in solar energy production, which is typical for its latitude.
Seasonal Solar Performance
Summer stands out as the most productive season, with an impressive 5.71 kWh per day for each kilowatt of installed solar capacity. Spring follows closely, generating 4.85 kWh/day. However, autumn sees a considerable drop to 2.99 kWh/day, while winter performance plummets to a mere 1.52 kWh/day.
These figures highlight the stark contrast between the warm and cold months, with summer producing nearly four times the energy of winter. This variation is primarily due to the changing angle of the sun and the shorter daylight hours during winter.
Optimal Panel Positioning
To maximize year-round energy production, fixed solar panels should be tilted at a 41-degree angle facing south. This angle is calculated to capture the most sunlight throughout the year, considering the location's latitude and the sun's changing position across seasons.
Environmental Considerations
While Rickenbach bei Wil's location is generally favorable for solar energy, there are some environmental factors to consider:
- Snow accumulation in winter can significantly reduce panel efficiency
- Fog, common in the region, may decrease solar radiation reaching the panels
To mitigate these issues, installing panels at a steeper angle can help shed snow more easily. Additionally, regular cleaning and maintenance can prevent buildup of snow, dust, or debris that might impede energy production.
Conclusion
Despite the challenges posed by winter months and occasional adverse weather conditions, Rickenbach bei Wil remains a viable location for solar PV installations. The strong performance during spring and summer months can offset the reduced winter output, making it a worthwhile investment for those looking to harness renewable energy in this Swiss locale.

Solar output per kW of installed solar PV by season in Rickenbach Bei Wil
Seasonal solar PV output for Latitude: 47.4497, Longitude: 9.0535 (Rickenbach Bei Wil, 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 Rickenbach Bei Wil, Switzerland
To maximize your solar PV system's energy output in Rickenbach Bei Wil, Switzerland (Lat/Long 47.4497, 9.0535) 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 Rickenbach Bei Wil, 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 Rickenbach Bei Wil, 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.

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 Rickenbach Bei Wil, 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 Rickenbach Bei Wil, Switzerland
The area around Rickenbach bei Wil, Switzerland, is characterized by a varied and picturesque topography typical of the Swiss Plateau region. This part of Switzerland features gently rolling hills, interspersed with small valleys and streams. The landscape is a mix of agricultural fields, meadows, and patches of forest, creating a patchwork of green spaces.
The terrain gradually rises towards the south and east, where it transitions into the foothills of the Alps. To the north and west, the land is generally flatter, with occasional gentle slopes. The region is dotted with small towns and villages, connected by winding roads that follow the natural contours of the land.
Rickenbach bei Wil itself sits at an elevation of approximately 600 meters above sea level. The surrounding area has modest elevation changes, with hills rising to around 700-800 meters in height. This topography creates a pleasant, undulating landscape that is neither too flat nor excessively mountainous.
Regarding areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, there are a few considerations to keep in mind:
The most suitable locations for solar PV in this region would likely be on the south-facing slopes of the gentle hills. These areas receive more direct sunlight throughout the day, maximizing the potential for solar energy generation. Open fields or meadows on these slopes, particularly those that are not prime agricultural land, could be ideal candidates for solar farms.
Flatter areas to the north and west of Rickenbach bei Wil might also be suitable for solar installations, as they offer large, unobstructed spaces. However, care should be taken to avoid using high-quality farmland for this purpose, as agriculture is an important part of the local economy and landscape.
It's worth noting that while the topography in this area is generally favorable for solar PV, the climate of Switzerland, with its frequent cloudy days and potential for snow in winter, may pose some challenges for solar energy production. Therefore, any large-scale solar project would need to carefully consider these factors alongside the topographical advantages of the region.
