Solar PV Analysis of Fislisbach, Switzerland
Fislisbach, Aargau, Switzerland, situated at 47.4399°N, 8.3026°E, presents a varied landscape for solar energy generation throughout the year. This location in the Northern Temperate Zone experiences significant seasonal fluctuations in solar output, which impacts the effectiveness of photovoltaic (PV) systems.
Seasonal Solar Performance
The solar energy potential in Fislisbach varies dramatically across seasons. Summer stands out as the most productive period, with an average daily output of 5.71 kWh per kW of installed solar capacity. Spring follows closely, yielding 4.85 kWh/day. Autumn sees a considerable drop to 2.99 kWh/day, while winter experiences the lowest output at just 1.52 kWh/day.
These figures highlight the substantial difference between peak and off-peak seasons, with summer producing nearly four times the energy of winter. This variation is primarily due to the changing sun angle and daylight hours throughout the year.
Optimal Panel Positioning
To maximize year-round solar energy production in Fislisbach, Aargau, fixed solar panels should be tilted at a 41-degree angle facing south. This optimal angle takes into account the location's latitude and the sun's position throughout the year, balancing energy capture across all seasons.
Environmental Considerations
While Fislisbach's location is generally favorable for solar energy, there are some environmental factors to consider:
- Snow accumulation in winter can temporarily reduce panel efficiency
- Fog, common in the Swiss Plateau region, may occasionally diminish solar radiation
To mitigate these issues, installing panels at the recommended 41-degree tilt helps shed snow more easily. Additionally, using high-quality, anti-reflective glass on panels can improve performance in foggy conditions.
Conclusion
Despite the seasonal variations, Fislisbach's location can be considered moderately favorable for solar PV installations. The substantial energy production during spring and summer months can offset the reduced output in autumn and winter. With proper panel positioning and preventative measures against environmental factors, solar energy remains a viable option for this Swiss location.

Ideally tilt fixed solar panels 41° South in Fislisbach, Switzerland
To maximize your solar PV system's energy output in Fislisbach, Switzerland (Lat/Long 47.4399, 8.3026) 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 Fislisbach, 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 Fislisbach, 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 Fislisbach, 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 Fislisbach, 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 Fislisbach, Switzerland
The area around Fislisbach, Switzerland, is characterized by a diverse and picturesque topography typical of the Swiss Plateau region. Fislisbach itself is situated in a gently rolling landscape, with small hills and shallow valleys creating a pleasant, undulating terrain.
To the north and east of Fislisbach, the land gradually slopes downward towards the Reuss River valley. This area is predominantly composed of open fields, meadows, and small patches of woodland. The terrain here is relatively flat, with occasional gentle rises and dips in the landscape.
To the south and west, the topography becomes more pronounced, with steeper hills and more pronounced valleys. This area marks the beginning of the transition towards the Jura Mountains, which lie further to the west. Here, you'll find a mix of forested hillsides and open agricultural land, creating a patchwork of different land uses.
Regarding areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, the relatively flat and open areas to the north and east of Fislisbach present the most promising opportunities. These locations offer several advantages for solar energy production:
- The flatter terrain makes construction and maintenance of solar arrays easier and more cost-effective.
- There are fewer natural obstacles like tall trees or steep hillsides that could cast shadows on the panels.
- The open fields provide ample space for large-scale installations without significant land-use conflicts.
However, it's important to note that any large-scale solar PV project would need to carefully consider local zoning regulations, environmental impact assessments, and the preservation of agricultural land, which is highly valued in Switzerland. Additionally, while the area around Fislisbach receives a moderate amount of sunlight, it may not be as ideal for solar energy production as some other regions with more consistent sunny weather.
In conclusion, while the varied topography around Fislisbach creates a beautiful landscape, the flatter areas to the north and east offer the most potential for large-scale solar PV development, should such projects be deemed appropriate for the region.
