Schaffhausen, Switzerland, situated at latitude 47.7191 and longitude 8.6246, presents a mixed picture for solar PV energy generation throughout the year. Located in the Northern Temperate Zone, this city experiences significant seasonal variations in solar energy production.
Seasonal Solar Performance
Summer stands out as the most productive season for solar energy in Schaffhausen, with an impressive average daily output of 5.71 kWh per kW of installed solar capacity. Spring follows closely behind, generating 4.85 kWh/day. These seasons offer the best conditions for solar energy production, with longer daylight hours and more direct sunlight.
Autumn sees a considerable drop in solar output, producing an average of 2.99 kWh/day. Winter presents the greatest challenge, with production plummeting to just 1.52 kWh/day. This stark contrast highlights the importance of efficient energy storage and alternative energy sources during the colder months.
Optimal Panel Installation
To maximize year-round solar energy production in Schaffhausen, fixed solar panels should be tilted at an angle of 41 degrees facing South. This optimal angle takes into account the city's latitude and the sun's position throughout the year, ensuring the best possible energy capture across all seasons.
Environmental and Weather Factors
Several factors can impact solar production in Schaffhausen:
- Snow accumulation in winter can significantly reduce panel efficiency
- Fog, common in the region, can decrease solar radiation reaching the panels
To mitigate these issues, consider installing panels at a steeper angle to encourage snow sliding off and using anti-reflective coatings to improve performance in low-light conditions. Regular cleaning and maintenance are also crucial to ensure optimal performance year-round.
While Schaffhausen's location presents challenges for consistent solar energy production throughout the year, proper installation techniques and consideration of local environmental factors can help maximize the potential of solar PV systems in this Swiss city.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Ideally tilt fixed solar panels 41° South in Schaffhausen, Switzerland
To maximize your solar PV system's energy output in Schaffhausen, Switzerland (Lat/Long 47.7191, 8.6246) 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 Schaffhausen, 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 Schaffhausen, 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 | 51° 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 Schaffhausen, 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 Schaffhausen, 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 Schaffhausen, Switzerland
The area around Schaffhausen, Switzerland, is characterized by a diverse and picturesque landscape. The city itself is nestled along the banks of the Rhine River, which forms a natural border between Switzerland and Germany. The topography in this region is a mix of rolling hills, river valleys, and some flatter areas.
To the north and east of Schaffhausen, the terrain is generally hilly, with elevations gradually increasing as you move away from the Rhine. These hills are part of the larger Randen mountain range, which extends into Germany. The landscape here is dotted with forests, meadows, and small agricultural plots.
South of Schaffhausen, the terrain becomes more varied. You'll find a combination of gentle slopes and broader valleys, interspersed with patches of woodland. This area is part of the Swiss Plateau, a relatively flat region that stretches across much of central Switzerland.
To the west, the landscape is dominated by the Rhine River and its valley. The river has carved a path through the surrounding hills, creating steep banks in some areas and wider floodplains in others. This region is known for its vineyards, which take advantage of the sunny, south-facing slopes.
Regarding large-scale solar PV installations, the most suitable areas near Schaffhausen would likely be found in the flatter regions to the south and southwest. These areas offer more expansive, open spaces that could accommodate large solar arrays without significant terrain modifications. The gently sloping fields in this direction receive good sun exposure and are less prone to shadowing from nearby hills.
Additionally, some of the south-facing slopes in the hilly areas north and east of Schaffhausen could potentially be used for solar installations, though these would likely be smaller in scale due to the more challenging terrain. However, it's important to note that any large-scale solar development would need to carefully consider environmental impacts, agricultural land use, and local regulations, as Switzerland places a high value on preserving its natural landscapes and agricultural heritage.
Switzerland solar PV Stats as a country
Switzerland ranks 25th in the world for cumulative solar PV capacity, with 3,449 total MW's of solar PV installed. This means that 4.70% of Switzerland's total energy as a country comes from solar PV (that's 16th in the world). Each year Switzerland is generating 399 Watts from solar PV per capita (Switzerland ranks 6th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Switzerland?
