Eningen unter Achalm, 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 affects its overall suitability for year-round solar PV production.
Seasonal Solar Performance
The location's solar performance varies dramatically across seasons. Summer stands out as the most productive period, with an impressive 5.55 kWh per day for each kilowatt of installed solar capacity. Spring follows with a respectable 4.50 kWh/day. However, autumn sees a significant drop to 2.75 kWh/day, while winter performance plummets to a mere 1.31 kWh/day.
These figures indicate that Eningen unter Achalm is most suitable for solar energy generation during the warmer months, particularly from late spring through early autumn. The extended daylight hours and typically clearer skies during this period contribute to the higher energy output.
Optimizing Solar Panel Installation
To maximize year-round solar production at this location, fixed solar panels should be tilted at an angle of 41 degrees facing south. This optimal angle takes into account the site's latitude and the sun's position throughout the year, helping to capture the most sunlight possible across all seasons.
Environmental and Weather Considerations
While Eningen unter Achalm doesn't face extreme environmental challenges, there are some factors that could impact solar production:
- Winter conditions: The significantly reduced output in winter is likely due to shorter days, lower sun angle, and increased cloud cover. Snow accumulation on panels could further reduce efficiency.
- Fog and overcast days: The region may experience foggy or overcast conditions, particularly in autumn and winter, which can diminish solar output.
To mitigate these issues, consider installing panels with anti-soiling coatings to reduce snow adherence and improve self-cleaning. Additionally, using micro-inverters or power optimizers can help maintain efficiency during partial shading conditions.
In conclusion, while Eningen unter Achalm is not ideal for year-round solar production due to its significant seasonal variations, it still offers good potential during warmer months. Proper installation techniques and equipment selection can help maximize energy generation despite the challenges posed by the local climate.

Solar output per kW of installed solar PV by season in Eningen Unter Achalm
Seasonal solar PV output for Latitude: 48.4858, Longitude: 9.2695 (Eningen Unter Achalm, 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 41° South in Eningen Unter Achalm, Germany
To maximize your solar PV system's energy output in Eningen Unter Achalm, Germany (Lat/Long 48.4858, 9.2695) 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 Eningen Unter Achalm, 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 Eningen Unter Achalm, Germany. 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 |
|---|---|---|---|
| 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 Eningen Unter Achalm, 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 Eningen Unter Achalm, Germany
Eningen unter Achalm is a town nestled in the picturesque landscape of Baden-Württemberg, Germany. The topography surrounding this area is characterized by a diverse mix of rolling hills, steep slopes, and flat valleys. The town itself sits at the foot of the Achalm, a prominent hill that rises to about 706 meters above sea level, dominating the local skyline. To the north and east of Eningen, the terrain gradually rises towards the Swabian Alb, a limestone mountain range that stretches across southern Germany. This area features a series of plateaus and escarpments, creating a rugged and varied landscape. The slopes of the Alb are often covered in dense forests, interspersed with open meadows and rocky outcrops. To the south and west, the land opens up into the broader Neckar Valley. This area is generally flatter, with gently undulating hills and wide, open spaces. The Neckar River, a major tributary of the Rhine, flows through this valley, shaping the surrounding terrain over millennia.
Potential for Large-Scale Solar PV
When considering areas nearby that would be most suited to large-scale solar PV installations, the flatter regions to the south and west of Eningen unter Achalm present the most promising opportunities. These areas in the Neckar Valley offer several advantages for solar energy production: Firstly, the relatively flat terrain makes construction and maintenance of large solar arrays more straightforward and cost-effective. There's less need for extensive earthworks or specialized mounting systems that might be required on steeper slopes. Secondly, these open areas are likely to receive more consistent sunlight throughout the day, with fewer obstructions from hills or forests that could cast shadows and reduce energy production. The wide, unobstructed spaces allow for optimal positioning of solar panels to capture maximum sunlight. Additionally, the proximity to the Neckar River might provide easier access to the electrical grid and transportation infrastructure, which are crucial for the development and operation of large-scale solar facilities. However, it's important to note that any large-scale solar project would need to balance energy production goals with environmental and agricultural considerations. The fertile lands of the Neckar Valley are also valuable for agriculture, so careful planning would be necessary to ensure that solar developments do not excessively impact food production or local ecosystems. While the hilly areas to the north and east may be less suitable for expansive solar farms, they could still accommodate smaller-scale installations or be utilized for other forms of renewable energy, such as wind power, contributing to a diverse and resilient energy landscape in the region.Germany solar PV Stats as a country
