Loye-sur-Arnon, France, situated at latitude 46.6564 and longitude 2.3842 in the Northern Temperate Zone, presents a mixed picture for solar PV energy generation throughout the year. The location experiences significant seasonal variations in solar output, which impacts its overall suitability for year-round solar energy production.
Seasonal Solar Performance
Summer stands out as the most productive season, with an impressive 5.82 kWh per day output for each kW of installed solar capacity. Spring follows closely behind, generating 5.09 kWh per day. These seasons offer ideal conditions for solar energy production, with longer daylight hours and typically clearer skies.
Autumn sees a noticeable decrease in solar output, dropping to 3.10 kWh per day. This reduction is likely due to shorter days and increased cloud cover. Winter presents the greatest challenge, with production plummeting to just 1.52 kWh per day. The combination of short days, low sun angle, and potentially overcast skies contributes to this significant drop in energy generation.
Optimizing Solar Panel Installation
To maximize year-round solar energy production in Loye-sur-Arnon, fixed solar panels should be tilted at a 40-degree angle facing south. This optimal angle has been calculated to capture the most sunlight throughout the year, considering the location's latitude and seasonal sun positions.
Environmental and Weather Factors
While Loye-sur-Arnon doesn't face extreme environmental challenges, there are some factors that could impact solar production:
- Winter snowfall: Snow accumulation on panels can temporarily reduce output. Installing panels at the optimal angle helps with snow shedding, and occasional manual clearing may be necessary.
- Autumn leaf fall: Nearby deciduous trees could drop leaves onto panels, requiring periodic cleaning to maintain efficiency.
To mitigate these issues, regular maintenance checks should be scheduled, particularly before and during winter. Additionally, strategic placement of panels away from overhanging trees can minimize leaf-related obstructions.
In conclusion, while Loye-sur-Arnon experiences excellent solar potential during spring and summer, the significant drop in autumn and winter production means that supplementary energy sources or energy storage solutions should be considered for year-round reliability. Despite these challenges, with proper installation and maintenance, solar PV can still be a valuable component of the local energy mix.

Solar output per kW of installed solar PV by season in Loye-sur-Arnon
Seasonal solar PV output for Latitude: 46.6564, Longitude: 2.3842 (Loye-sur-Arnon, 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 40° South in Loye-sur-Arnon, France
To maximize your solar PV system's energy output in Loye-sur-Arnon, France (Lat/Long 46.6564, 2.3842) throughout the year, you should tilt your panels at an angle of 40° 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 Loye-sur-Arnon, 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 Loye-sur-Arnon, France. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 40° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 30° South in Summer | 50° South in Autumn | 60° South in Winter | 39° 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 Loye-sur-Arnon, 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 Loye-sur-Arnon, 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 Loye-sur-Arnon, France
The area surrounding Loye-sur-Arnon, France, is characterized by a gently rolling landscape typical of the central French countryside. This region, located in the department of Cher, features a mix of agricultural fields, small woodlands, and scattered rural settlements. The terrain is predominantly composed of low hills and shallow valleys, with elevations generally ranging from 200 to 300 meters above sea level. The Arnon River, after which the commune is partially named, flows through the area, carving a modest valley in the landscape. This waterway and its tributaries have shaped the local topography over time, creating subtle undulations in the terrain. The land is primarily used for farming, with a patchwork of crop fields and pastures dominating the visual landscape.
Potential for Solar PV Installation
When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The gently sloping terrain in the vicinity of Loye-sur-Arnon offers some advantages for solar energy development. South-facing slopes, in particular, would be ideal candidates for solar farms as they receive more direct sunlight throughout the day. Agricultural lands that are less productive or fallow fields could potentially be repurposed for solar energy production. These areas often have the advantage of being relatively flat, which simplifies the installation process and reduces construction costs. Additionally, they typically have fewer obstacles that could cast shadows on solar panels, such as large trees or buildings. It's important to note that any large-scale solar PV project would need to balance energy production goals with environmental and agricultural considerations. Areas of ecological importance, such as wetlands near the Arnon River or dense forested regions, would likely be unsuitable for solar development. Similarly, highly productive agricultural land might be preserved for food production rather than converted to energy generation. The most promising locations for solar PV installations would likely be found on the outskirts of existing settlements, where they can be connected to the electrical grid more easily. South-facing hillsides or plateaus that are not currently used for intensive agriculture could offer an excellent compromise between optimal sun exposure and minimal disruption to local ecosystems and farming practices.France solar PV Stats as a country
