Solar PV Analysis of Ettenheim, Germany
Ettenheim, located in Baden-Wurttemberg, Germany, presents a moderate opportunity for solar PV energy generation throughout the year. Situated in the Northern Temperate Zone, this location experiences significant seasonal variations in solar energy production.
Seasonal Solar Performance
Summer stands out as the most productive season, with an average daily output of 5.52 kWh per kW of installed solar capacity. Spring follows closely, yielding 4.72 kWh/day. Autumn sees a considerable drop to 2.81 kWh/day, while winter experiences the lowest production at 1.32 kWh/day.
The substantial difference between summer and winter production highlights the impact of seasonal changes on solar energy generation in Ettenheim. The longer days and higher sun angle during summer months contribute to peak performance, making it an ideal time for solar energy harvesting.
Optimal Panel Placement
To maximize year-round solar production in Ettenheim, fixed solar panels should be tilted at a 41-degree angle facing south. This optimal angle takes into account the location's latitude and the sun's position throughout the year, ensuring the best possible energy capture across all seasons.
Environmental Considerations
While Ettenheim's location is generally favorable for solar energy production, there are some environmental factors to consider:
- Cloud cover: The region can experience cloudy days, particularly in autumn and winter, which may reduce solar efficiency.
- Snow accumulation: Winter snowfall could temporarily cover panels, hindering energy production.
To mitigate these issues, consider installing panels at a steeper angle to promote snow sliding off and using high-efficiency panels that perform well in low-light conditions. Regular maintenance, including snow removal and panel cleaning, can help maintain optimal performance throughout the year.
In conclusion, while Ettenheim's solar potential varies significantly across seasons, proper panel placement and maintenance can ensure a reliable source of renewable energy, with summer and spring offering the most productive periods for solar PV generation.

Solar output per kW of installed solar PV by season in Ettenheim
Seasonal solar PV output for Latitude: 48.2547, Longitude: 7.817 (Ettenheim, 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 Ettenheim, Germany
To maximize your solar PV system's energy output in Ettenheim, Germany (Lat/Long 48.2547, 7.817) 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 Ettenheim, 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 Ettenheim, 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 | 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 Ettenheim, Germany
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 Ettenheim, 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 Ettenheim, Germany
The area around Ettenheim, Germany, is characterized by a diverse and picturesque landscape. Ettenheim itself is situated in the Upper Rhine Plain, a relatively flat region that extends along the Rhine River. To the east of the town, the terrain begins to rise as it transitions into the foothills of the Black Forest, a mountainous region known for its dense forests and scenic beauty.
The immediate vicinity of Ettenheim features gently rolling hills and agricultural land. Vineyards and orchards are common sights in this area, taking advantage of the fertile soil and favorable climate. Small streams and creeks crisscross the landscape, eventually making their way to the Rhine River to the west.
As you move further east from Ettenheim, the elevation gradually increases, and the terrain becomes more rugged and forested. This transition marks the beginning of the Black Forest, with its characteristic mix of coniferous and deciduous trees covering the hillsides and valleys.
When considering areas nearby that would be most suited to large-scale solar PV (photovoltaic) installations, the flat or gently sloping agricultural lands to the west and southwest of Ettenheim present the best opportunities. These areas offer several advantages for solar energy production:
- They receive ample sunlight due to their open, unobstructed nature.
- The relatively flat terrain makes construction and maintenance easier.
- There are fewer conflicts with forested areas or protected natural habitats.
- The proximity to existing infrastructure and power grids facilitates energy distribution.
However, it's important to note that the use of agricultural land for solar installations can be controversial, as it may compete with food production. Any large-scale solar project would need to carefully balance energy needs with agricultural preservation and local community interests.
The more hilly and forested areas to the east, while picturesque, are generally less suitable for large-scale solar installations due to shading from trees, increased construction challenges on sloped terrain, and potential environmental concerns related to forest preservation.
