Schmitten, Fribourg, Switzerland, located at 46.8591° N, 7.2537° E, presents a mixed picture for solar PV 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 solar installations.

Seasonal Solar Performance

Summer stands out as the most productive season, with an impressive 6.00 kWh per day output for each kW of installed solar capacity. Spring follows as the second-best season, generating 4.89 kWh per day. Autumn sees a noticeable drop to 3.09 kWh per day, while winter performance plummets to a mere 1.58 kWh per day.

These figures highlight the stark contrast between summer and winter solar production in Schmitten. The long, sunny days of summer provide ideal conditions for solar energy generation, while the short, often overcast days of winter significantly hamper output.

Optimal Panel Positioning

To maximize year-round solar production at this location, fixed solar panels should be tilted at a 40-degree angle facing south. This orientation helps capture the most sunlight throughout the year, balancing the varying sun angles across seasons.

Environmental and Weather Factors

Several factors can impede solar production in Schmitten:

1. Snow accumulation in winter can cover panels, reducing efficiency
2. Frequent cloud cover, especially in autumn and winter, limits solar exposure

To mitigate these issues, consider installing panels at a steeper angle to encourage snow sliding off. Additionally, use high-quality, anti-reflective coatings on panels to maximize light absorption even during overcast conditions. Regular maintenance, including snow removal, is crucial for ensuring optimal performance year-round.

In conclusion, while Schmitten's location is not ideal for consistent year-round solar production, it still offers significant potential, especially during spring and summer months. With proper installation techniques and maintenance, solar PV can be a viable renewable energy source for this Swiss community.

Solar output per kW of installed solar PV by season in Schmitten

Seasonal solar PV output for Latitude: 46.8591, Longitude: 7.2537 (Schmitten, 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 Schmitten, Switzerland

To maximize your solar PV system's energy output in Schmitten, Switzerland (Lat/Long 46.8591, 7.2537) 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 Schmitten, 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 Schmitten, 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	60° South in Winter	39° 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 Schmitten, 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 Schmitten, Switzerland.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Schmitten, Switzerland

The topography around Schmitten, Switzerland is characterized by rolling hills and gentle slopes typical of the Swiss Plateau region. Situated in the canton of Fribourg, Schmitten is nestled within a landscape of lush green fields, scattered forests, and small streams. The terrain gradually rises towards the east, where the foothills of the Alps begin to emerge. The area surrounding Schmitten features a mix of agricultural land and small settlements. The countryside is dotted with farms and pastures, interspersed with patches of woodland. The landscape is generally open, with few steep inclines or dramatic changes in elevation. This gentle topography is part of the broader Swiss Plateau, which stretches between the Jura Mountains to the northwest and the Alps to the southeast.

Potential for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The gently sloping terrain around Schmitten offers some promising locations for solar farms. South-facing slopes, in particular, would be ideal as they receive more direct sunlight throughout the day. The agricultural areas to the south and southwest of Schmitten present opportunities for solar development. These open fields, if not crucial for food production, could potentially accommodate large arrays of solar panels. The relatively flat terrain in these areas would simplify installation and reduce costs associated with land preparation. However, it's important to note that Switzerland places a high value on its agricultural land and natural landscapes. Any large-scale solar projects would need to carefully balance energy production goals with environmental and agricultural considerations. Areas that are already developed or have less agricultural value might be prioritized for solar installations. The region between Schmitten and the nearby town of Düdingen could also offer suitable locations for solar farms. This area features a mix of open spaces and gentle slopes that could be conducive to solar panel placement. Additionally, its proximity to existing infrastructure might facilitate grid connection and maintenance. While the immediate vicinity of Schmitten provides some potential for solar PV development, larger and more optimal areas might be found further afield in the broader Swiss Plateau region. These could include former industrial sites, areas adjacent to highways, or other locations where large-scale solar installations would have minimal impact on valuable agricultural land or natural habitats.
