Vesoul, France presents a moderately suitable location for year-round solar PV energy generation, though with significant seasonal variations that are typical for its Northern Temperate Zone position.

Seasonal Solar Performance

The location shows strong seasonal contrasts in solar energy production. Summer delivers the highest output at 5.71 kWh per day per kW of installed capacity, making it the prime season for solar generation. Spring follows as the second-best period with 4.83 kWh per day per kW, offering excellent conditions for solar energy production. Autumn sees a notable decline to 2.98 kWh per day per kW, while winter presents the most challenging conditions with only 1.42 kWh per day per kW. This winter figure represents less than 25% of summer production, highlighting the significant seasonal dependency of solar generation at this latitude.

Optimal Panel Configuration

For maximum year-round energy production at Vesoul, solar panels should be installed at a fixed tilt angle of 41 degrees facing south. This angle has been calculated to optimize total annual output by accounting for the sun's varying position throughout the year and weighting for daily solar potential.

Local Environmental Challenges

Several environmental and weather factors in the Vesoul region can impact solar energy production:

• Frequent cloud cover and overcast conditions, particularly during autumn and winter months
• Morning fog, which is common in the Franche-Comté region due to its continental climate
• Snow accumulation during winter months that can block panel surfaces
• Higher humidity levels that may contribute to atmospheric haze

Preventative Installation Measures

To maximize solar energy production despite these challenges, several installation strategies should be considered: The 41-degree tilt angle not only optimizes sun exposure but also helps snow slide off panels more easily during winter. Installing panels with adequate spacing between rows prevents shading and allows better air circulation for cooling. Regular maintenance schedules become particularly important, including cleaning panels to remove dust, pollen, and other debris that accumulate more readily in humid conditions. Anti-reflective coatings can help panels perform better during hazy or partially cloudy conditions. Proper drainage around panel installations prevents water pooling that could create localized humidity issues. Consider installing monitoring systems to quickly identify any panels underperforming due to environmental factors, allowing for prompt corrective action.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

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

Seasonal solar PV output for Latitude: 47.6263, Longitude: 6.138 (Vesoul, 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 41° South in Vesoul, France

To maximize your solar PV system's energy output in Vesoul, France (Lat/Long 47.6263, 6.138) 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 Vesoul, 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 Vesoul, France. 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
31° 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 Vesoul, 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 Vesoul, France.

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 Vesoul, France

Topographical Features Around Vesoul

Vesoul sits in the Haute-Saône department of eastern France, positioned within a gently undulating landscape that forms part of the broader Franche-Comté region. The city itself occupies a strategic position at approximately 220 meters above sea level, nestled in a valley formed by the Durgeon River, a tributary of the Saône. This river valley creates a natural corridor through the surrounding terrain, with the urban area spreading across relatively flat alluvial plains.

The topography immediately surrounding Vesoul is characterized by low hills and gentle slopes that rarely exceed 400 meters in elevation. To the west and northwest, the landscape gradually rises toward the Plateau de Langres, while eastward the terrain begins its slow ascent toward the Vosges Mountains, though these more dramatic peaks remain distant from the immediate Vesoul area. The local relief consists primarily of rounded hills covered with mixed agricultural land and scattered woodlands, creating a patchwork landscape typical of this transitional zone between the Paris Basin and the Alpine regions.

The geological foundation beneath Vesoul consists mainly of sedimentary rocks, including limestone and sandstone formations that have been shaped by centuries of erosion. This has resulted in a relatively stable terrain with good drainage characteristics. Small valleys and gentle ridges create a rolling countryside, with most slopes remaining moderate enough to support both agriculture and potential infrastructure development.

Solar PV Suitability in the Regional Landscape

The most promising areas for large-scale solar photovoltaic installations around Vesoul would be the gently sloping hillsides that face south and southwest, particularly those rising from the Durgeon valley toward the surrounding plateaus. These elevated positions offer several advantages, including reduced risk of fog accumulation that can affect lower-lying areas, while their moderate gradients make them accessible for construction and maintenance activities.

The agricultural plains extending northwest and southwest of the city present excellent opportunities for ground-mounted solar farms. These areas feature relatively flat terrain with minimal shading from topographical features, and much of this land consists of large, consolidated field systems that could accommodate substantial installations. The gentle undulations in these plains actually provide slight advantages, as south-facing slopes can optimize panel orientation naturally.

Areas to the east of Vesoul, where the landscape begins rising toward the more distant Vosges foothills, offer mixed potential depending on specific site characteristics. South-facing slopes in this direction could be highly suitable, while north-facing aspects and heavily forested areas would be less appropriate. The key consideration in these slightly more elevated areas is ensuring that installations are positioned to avoid shadowing from adjacent ridgelines or extensive tree cover.

The immediate river valley where Vesoul sits would be less ideal for large-scale solar development due to the combination of existing urban development, potential flooding concerns, and the tendency for morning fog to linger in low-lying areas along watercourses. However, the broader valley system does contain some elevated terraces that could support smaller installations while avoiding the most flood-prone zones near the river itself.
