Frenkendorf, Switzerland, situated at 47.5083°N, 7.703°E, presents a mixed picture for solar energy generation throughout the year. This location in the Northern Temperate Zone experiences significant seasonal variations in solar output, which impacts the overall efficiency of photovoltaic (PV) systems.
Seasonal Solar Performance
The solar energy production in Frenkendorf follows a predictable pattern aligned with the changing seasons:
- Summer: 5.69 kWh/day per kW installed
- Spring: 4.83 kWh/day per kW installed
- Autumn: 2.95 kWh/day per kW installed
- Winter: 1.39 kWh/day per kW installed
Summer and spring clearly stand out as the most productive seasons for solar energy generation in Frenkendorf. During these months, longer daylight hours and higher sun angles contribute to increased solar panel efficiency. The peak performance in summer makes it an ideal time for maximizing solar energy production.
Winter Challenges
Winter presents the greatest challenge for solar energy production in Frenkendorf. The significant drop in output during this season is due to shorter days, lower sun angles, and potentially increased cloud cover. While solar panels still generate electricity in winter, the reduced output may necessitate supplementary energy sources or energy storage solutions to meet demand during this period.
Optimal Panel Tilt
For fixed solar panel installations in Frenkendorf, the ideal tilt angle to maximize year-round production is 40 degrees facing south. This angle is calculated to optimize the panels' exposure to sunlight throughout the year, balancing the varying sun angles across seasons.
Environmental Considerations
While Frenkendorf's location is generally suitable for solar energy production, there are some environmental factors to consider. The region can experience foggy conditions, particularly in autumn and winter, which may temporarily reduce solar panel efficiency. Additionally, snowfall in winter can cover panels, impeding energy production.
To mitigate these issues, installers can implement preventative measures such as using self-cleaning panels, installing panels at steeper angles to encourage snow sliding off, and incorporating snow sensors and heating elements for automatic snow removal. Regular maintenance and cleaning schedules can also help ensure optimal performance year-round.
In conclusion, while Frenkendorf's location presents some challenges for year-round solar energy production, particularly in winter, it remains a viable option for renewable energy generation. With proper planning, optimal panel positioning, and preventative measures, solar PV systems can effectively contribute to the area's energy needs, especially during the more productive spring and summer months.

Solar output per kW of installed solar PV by season in Frenkendorf
Seasonal solar PV output for Latitude: 47.5083, Longitude: 7.703 (Frenkendorf, 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 40° South in Frenkendorf, Switzerland
To maximize your solar PV system's energy output in Frenkendorf, Switzerland (Lat/Long 47.5083, 7.703) throughout the year, you should tilt your panels at an angle of 40° 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 Frenkendorf, 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 Frenkendorf, Switzerland. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 40° 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.

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 Frenkendorf, Switzerland
Frenkendorf, Switzerland, is nestled in a picturesque region characterized by diverse topography. The area surrounding this small town features a mix of gently rolling hills, shallow valleys, and some steeper slopes as one moves towards the nearby Jura Mountains. The landscape is dotted with lush forests, open meadows, and agricultural fields, creating a patchwork of green hues across the terrain. To the north and east of Frenkendorf, the land gradually descends towards the Rhine River valley, offering relatively flat expanses interspersed with minor undulations. This area is predominantly used for agriculture and urban development. To the south and west, the terrain becomes more pronounced, with hills rising steadily towards the foothills of the Jura Mountains.
Potential for Large-Scale Solar PV
When considering areas suitable for large-scale solar photovoltaic (PV) installations near Frenkendorf, several factors come into play. The most promising locations would be those that offer a combination of favorable topography, minimal shading, and proximity to existing infrastructure. The gently sloping areas to the north and east of Frenkendorf present the best opportunities for solar PV development. These regions benefit from relatively flat terrain, which simplifies installation and reduces construction costs. Additionally, the open nature of the landscape in this direction minimizes potential shading issues from natural features or buildings. Agricultural lands in the vicinity, particularly those with south-facing slopes, could also be suitable for solar PV installations. These areas often provide large, unobstructed spaces ideal for solar arrays. However, careful consideration would need to be given to balancing energy production with agricultural needs. It's worth noting that while the hilly regions to the south and west may receive good solar exposure, the more challenging terrain could increase installation complexity and costs. Nevertheless, some of the south-facing slopes in these areas could still be viable options for smaller-scale solar projects. Any large-scale solar PV development would need to take into account local regulations, environmental considerations, and grid connection possibilities. The proximity to urban areas like Basel could be advantageous for energy distribution, but it may also limit available space for extensive solar farms.Switzerland solar PV Stats as a country
