Freiberg am Neckar, located in Baden-Württemberg, Germany, presents a mixed picture for solar energy generation. This Northern Temperate Zone location experiences significant seasonal variations in solar output, which impacts the overall efficiency of photovoltaic (PV) systems throughout the year.
Seasonal Solar Performance
Summer stands out as the most productive season, with an impressive 5.55 kWh per day for each kilowatt of installed solar capacity. Spring follows closely, generating 4.50 kWh/day. However, the output drops considerably during autumn (2.75 kWh/day) and reaches its lowest point in winter (1.31 kWh/day).
These figures highlight the stark contrast between the warm and cold months, with summer producing more than four times the energy of winter. This variation is typical for locations in the Northern Temperate Zone, where daylight hours and sun intensity fluctuate significantly across seasons.
Optimal Panel Positioning
To maximize year-round energy production, fixed solar panels in Freiberg am Neckar should be tilted at a 42-degree angle facing south. This optimal angle helps balance the seasonal variations, capturing more sunlight during the less productive winter months while still performing efficiently in summer.
Best Times for Solar Generation
The most ideal period for solar energy production in this location is from late spring through early autumn. During these months, longer days and higher sun angles contribute to increased solar output. July and August are typically the peak months for solar generation.
Environmental Considerations
While Freiberg am Neckar doesn't face extreme environmental challenges for solar production, there are some factors to consider:
- Cloud cover: The region experiences frequent cloudy days, especially in winter, which can reduce solar efficiency.
- Snow: Winter snowfall can temporarily cover panels, reducing output.
To mitigate these issues, consider installing panels at a steeper angle to encourage snow slide-off and using high-efficiency panels that perform better in low-light conditions. Regular maintenance, including snow removal and panel cleaning, can help maintain optimal performance throughout the year.
In conclusion, while Freiberg am Neckar isn't ideal for year-round solar production due to significant seasonal variations, it still offers good potential, especially during the warmer months. With proper panel positioning and maintenance, a solar PV system can provide substantial energy contributions to local power needs.

Solar output per kW of installed solar PV by season in Freiberg Am Neckar
Seasonal solar PV output for Latitude: 48.9339, Longitude: 9.197 (Freiberg Am Neckar, Germany), 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 42° South in Freiberg Am Neckar, Germany
To maximize your solar PV system's energy output in Freiberg Am Neckar, Germany (Lat/Long 48.9339, 9.197) throughout the year, you should tilt your panels at an angle of 42° 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 Freiberg Am Neckar, Germany
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 Freiberg Am Neckar, Germany. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 42° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 32° South in Summer | 51° South in Autumn | 62° South in Winter | 41° 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 Freiberg Am Neckar, Germany.
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 Freiberg Am Neckar, Germany
The area surrounding Freiberg am Neckar, Germany, is characterized by a diverse and picturesque landscape. Situated in the southwestern part of the country, this region features a mix of gently rolling hills, fertile valleys, and forested areas. The town itself is nestled along the banks of the Neckar River, which has carved its way through the landscape over millennia, creating a scenic river valley. To the west and northwest of Freiberg am Neckar, the terrain gradually rises into the foothills of the Black Forest, a mountainous region known for its dense woodlands and steep slopes. These areas are generally less suitable for large-scale solar installations due to their uneven terrain and forest cover. To the east and southeast, the land opens up into more expansive, flatter areas that are part of the broader Neckar valley. These regions are primarily used for agriculture, with fields and meadows stretching across the landscape. The relatively level terrain in this direction offers more potential for solar PV development.
Potential Areas for Large-Scale Solar PV
When considering locations for large-scale solar PV installations near Freiberg am Neckar, the most suitable areas would likely be found in the flatter, more open spaces to the east and southeast of the town. These areas offer several advantages for solar energy development: Firstly, the relatively level terrain in these directions would simplify the construction and maintenance of solar arrays. Flat or gently sloping land is ideal for maximizing sun exposure and minimizing installation costs. Secondly, these areas are predominantly agricultural, which means there are large, unobstructed spaces that could potentially be repurposed or shared with solar installations. Many farmers are increasingly open to the idea of solar farms as an additional source of income. Thirdly, the open nature of the landscape in these directions means there are fewer natural obstacles like forests or steep hills that could cast shadows or impede solar panel efficiency. However, it's important to note that any large-scale solar development would need to balance energy production goals with preserving the region's agricultural heritage and natural beauty. Careful planning and community engagement would be crucial to ensure that solar projects are implemented in a way that respects local land use priorities and environmental considerations.Germany solar PV Stats as a country
