Golbey, Grand Est, France is a location with varying solar energy potential throughout the year. Situated in the Northern Temperate Zone, this site experiences significant seasonal fluctuations in solar electricity production that are worth considering for anyone planning a solar PV installation.

Seasonal Solar Production

The solar energy generation at this location shows a clear pattern across the seasons. Summer is the most productive period, yielding an average of 5.47 kWh per day for each kilowatt of installed solar capacity. Spring follows as the second most productive season with 4.66 kWh/day per kW installed. Autumn sees a significant drop to 2.75 kWh/day, while winter production falls to just 1.27 kWh/day per kW installed.

This seasonal variation means that a solar installation in Golbey will produce more than four times as much electricity in summer compared to winter. The gradual increase from winter to spring and summer, followed by a decline into autumn, creates a bell-curve pattern of annual production.

Optimal Panel Installation

For fixed solar panel installations in Golbey, Grand Est, the ideal tilt angle to maximize year-round electricity production is 41 degrees facing South. This angle has been calculated to optimize the capture of available sunlight throughout the year, accounting for the Earth's elliptical orbit and the site's specific latitude.

Environmental and Weather Considerations

Several local factors could potentially impact solar production at this location:

• Snow accumulation during winter months can temporarily reduce production if panels become covered, though the steep 41-degree tilt helps with natural snow shedding
• Typical cloud cover in the northeastern French climate, particularly during autumn and winter
• Potential morning fog in the Moselle valley region that could delay full production on some days
• Occasional hail storms that could pose a physical risk to panels

To mitigate these challenges, installation best practices include using durable, hail-resistant panels, implementing automated or easy manual snow-clearing methods, and ensuring panels are elevated enough to maximize exposure during low-angle winter sunlight. Regular cleaning maintenance, particularly after autumn leaf fall, will help maintain optimal performance.

Overall, while Golbey isn't among Europe's most ideal solar locations, a properly designed system with the correct tilt angle can still provide significant energy production, particularly from March through September when more than 75% of the annual production can be expected.

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 Golbey

Seasonal solar PV output for Latitude: 48.1987, Longitude: 6.445 (Golbey, 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 Golbey, France

To maximize your solar PV system's energy output in Golbey, France (Lat/Long 48.1987, 6.445) 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 Golbey, 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 Golbey, 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
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 Golbey, 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 Golbey, 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 Golbey, France

The topography around Golbey, France presents a varied landscape situated in the northeastern part of the country within the Vosges department. Golbey lies in a transitional zone between the Moselle River valley and the foothills of the Vosges Mountains. The terrain in this region is characterized by gentle rolling hills interspersed with flat plains, particularly along the Moselle River which flows nearby. The elevation in Golbey itself is approximately 340 meters above sea level, with surrounding areas ranging from about 330 meters in the valley to over 400 meters in the nearby hills. To the east of Golbey, the landscape gradually rises toward the Vosges Mountains, with increasingly steep slopes and higher elevations. These mountains, though not immediately adjacent to Golbey, influence the regional topography with their foothills creating a more undulating terrain in that direction. To the west, the land tends to be flatter as it follows the Moselle River valley.

Suitable Areas for Solar PV Development

For large-scale solar photovoltaic installations near Golbey, several areas present favorable conditions based on topographical considerations. The gently sloping south-facing hillsides to the north and northwest of Golbey offer particularly promising locations. These areas benefit from optimal sun exposure throughout the day while avoiding the steeper terrain of the Vosges foothills to the east. The relatively flat agricultural plains that extend southwest of Golbey along the Moselle valley also present suitable conditions for large-scale solar development. These areas combine favorable topography with good accessibility via the existing road network, which is an important logistical consideration for construction and maintenance of large solar installations. Areas to avoid would include the steeper eastern slopes that rise toward the Vosges Mountains, as these present construction challenges and potentially less optimal sun angles. Similarly, the immediate river valley floors may be subject to morning fog or mist patterns that could reduce solar efficiency, as well as potential flooding concerns. The plateaus located approximately 5-7 kilometers west of Golbey offer another promising option, as they combine relatively flat terrain at higher elevations with minimal shadowing from surrounding features. These higher plateaus also tend to experience less fog than the river valleys, providing more consistent solar exposure. When considering large-scale solar development in this region, it's worth noting that the moderate topographical relief generally means that extensive earthworks can be minimized in many locations, which represents a significant advantage from both environmental and economic perspectives.
