Solar PV Analysis of Bouxwiller, France
Bouxwiller, Grand Est, France, situated at 48.8233° N latitude and 7.4856° E longitude, presents a mixed picture for solar energy generation throughout the year. This location in the Northern Temperate Zone experiences significant seasonal variations in solar output, which affects the overall efficiency of photovoltaic (PV) systems.
Seasonal Solar Performance
The solar energy potential in Bouxwiller varies considerably across the four seasons. Summer stands out as the most productive period, with an average daily output of 5.52 kWh per kW of installed solar capacity. Spring follows closely, generating 4.72 kWh/day. However, autumn sees a substantial drop to 2.81 kWh/day, while winter performance plummets to a mere 1.32 kWh/day.
These figures highlight the stark contrast between the warm and cold seasons, with summer producing more than four times the energy of winter. This disparity underscores the importance of efficient energy storage solutions to balance supply throughout the year.
Optimal Panel Configuration
To maximize year-round solar energy production in Bouxwiller, Grand Est, fixed solar panels should be tilted at a 42-degree angle facing south. This optimal angle has been calculated considering the location's latitude, daily solar elevation angles, and weighted by NASA's solar irradiance data.
Environmental Considerations
While Bouxwiller doesn't face extreme environmental challenges, there are factors that could impact solar production:
- Cloud cover: The region experiences frequent cloudy days, especially in autumn and winter, which can reduce solar efficiency.
- Snow accumulation: Winter snowfall might temporarily cover panels, impeding 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 better in low-light conditions. Regular maintenance, including snow removal and panel cleaning, can also help maintain optimal performance.
Conclusion
While Bouxwiller's location is not ideal for year-round solar energy production due to significant seasonal variations, it still offers substantial potential, particularly from spring through autumn. With proper panel placement and maintenance, solar PV systems can provide a valuable contribution to the local energy mix, especially when combined with other renewable energy sources to compensate for winter's reduced output.

Solar output per kW of installed solar PV by season in Bouxwiller
Seasonal solar PV output for Latitude: 48.8233, Longitude: 7.4856 (Bouxwiller, France), 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 Bouxwiller, France
To maximize your solar PV system's energy output in Bouxwiller, France (Lat/Long 48.8233, 7.4856) 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 Bouxwiller, France
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 Bouxwiller, France. 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.
Calculate solar panel row spacing in Bouxwiller, France
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 Bouxwiller, France.
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 Bouxwiller, France
The area around Bouxwiller, France, is characterized by a diverse and picturesque landscape typical of the Alsace region. Situated in the foothills of the Vosges Mountains, Bouxwiller is surrounded by gently rolling hills and valleys. The terrain gradually rises as you move westward towards the Vosges, while to the east, it transitions into the flatter plains of the Rhine Valley.
The immediate vicinity of Bouxwiller features a mix of agricultural lands, forests, and small settlements. The hills in this area are generally modest in height, with elevations ranging from about 200 to 400 meters above sea level. These hills are often covered with a patchwork of fields, orchards, and woodlands, creating a varied and visually appealing landscape.
Regarding large-scale solar PV (photovoltaic) installations, the most suitable areas nearby would likely be found in the flatter regions to the east of Bouxwiller, as you approach the Rhine Valley. These areas offer several advantages for solar energy production:
- Flatter terrain: The more level ground makes it easier and less expensive to install large arrays of solar panels.
- Fewer obstructions: With fewer hills and forests, there's less shadowing and obstruction of sunlight.
- Agricultural land: Some of the agricultural areas might be suitable for dual-use solar installations, where farming can continue beneath elevated solar panels.
- Proximity to infrastructure: Being closer to the more densely populated Rhine Valley means easier access to electrical grids and transportation networks.
However, it's important to note that any large-scale solar project would need to balance energy production goals with preserving the region's natural beauty and agricultural heritage. Environmental impact assessments and local community consultations would be crucial steps in identifying the most appropriate locations for such developments.
