Villars-les-Dombes, France, located at latitude 45.9977 and longitude 5.0237, offers a moderate potential for solar energy generation throughout the year. This location in the Northern Temperate Zone experiences significant seasonal variations in solar output, which impacts the overall efficiency of solar PV systems.

Seasonal Solar Performance

The solar energy production at this location varies considerably across the four seasons. Summer stands out as the most productive period, with an average daily output of 6.20 kWh per kW of installed solar capacity. Spring follows closely, generating 5.31 kWh/day. However, there's a sharp decline in output during autumn (3.11 kWh/day) and winter (1.62 kWh/day).

These figures indicate that solar energy generation is most effective from late spring through early autumn. During this period, longer days and higher sun angles contribute to increased solar panel efficiency. Conversely, the winter months present challenges due to shorter days and lower sun angles, resulting in significantly reduced energy production.

Optimal Panel Tilt

For fixed panel installations in Villars-les-Dombes, the ideal tilt angle to maximize year-round solar production is 39 degrees facing south. This angle is calculated to optimize the panels' exposure to sunlight throughout the year, taking into account the location's latitude and seasonal sun positions.

Environmental and Weather Considerations

While Villars-les-Dombes doesn't face extreme environmental challenges, there are some factors that could impact solar production:

• Cloud cover: The region can experience periods of overcast weather, particularly in autumn and winter, which may reduce solar output.
• Snow: Winter snowfall, though not typically heavy, could temporarily cover panels and decrease efficiency.

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 cleaning panels of snow or debris, can help maintain optimal performance.

In conclusion, while Villars-les-Dombes is not an ideal location for year-round solar energy production due to significant seasonal variations, it still offers good potential, especially during the summer months. Proper installation techniques and regular maintenance can help maximize energy output throughout the year.

Solar output per kW of installed solar PV by season in Villars-les-Dombes

Seasonal solar PV output for Latitude: 45.9977, Longitude: 5.0237 (Villars-les-Dombes, 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 39° South in Villars-les-Dombes, France

To maximize your solar PV system's energy output in Villars-les-Dombes, France (Lat/Long 45.9977, 5.0237) throughout the year, you should tilt your panels at an angle of 39° 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 Villars-les-Dombes, 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 Villars-les-Dombes, France. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 39° 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	49° South in Autumn	60° South in Winter	38° 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 Villars-les-Dombes, 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 Villars-les-Dombes, 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 Villars-les-Dombes, France

The topography around Villars-les-Dombes, France, is characterized by a gently rolling landscape typical of the Dombes region. This area is situated in the eastern part of France, in the Ain department, and is known for its numerous ponds and lakes. The terrain is predominantly flat to slightly undulating, with elevations ranging from approximately 270 to 300 meters above sea level. The surrounding countryside is a mosaic of agricultural fields, small woodlands, and the distinctive ponds that give the Dombes region its unique character. These ponds, created centuries ago for fish farming, contribute to the area's biodiversity and create a picturesque landscape. The soil in this region is generally clayey, which helps retain water and supports the pond ecosystem.

Potential for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The relatively flat terrain in much of the surrounding area provides favorable conditions for solar panel deployment, as it minimizes shading issues and simplifies installation processes. Agricultural lands that are less productive or fallow fields could be potential candidates for solar PV projects. These areas often have good sun exposure and are already connected to road networks, which can facilitate construction and maintenance. However, it's important to balance energy production with preserving valuable agricultural land. Some of the gently sloping hillsides in the region, particularly those facing south or southwest, could offer optimal positioning for solar panels. These locations would receive more direct sunlight throughout the day, potentially increasing energy yield. It's worth noting that while the numerous ponds in the area might seem like potential sites for floating solar installations, their ecological importance may preclude such use. Instead, focus should be on identifying suitable terrestrial sites that do not compromise the region's unique aquatic ecosystems. Any large-scale solar PV project in this area would need to carefully consider environmental impacts, local zoning regulations, and grid connection possibilities. The proximity to existing electrical infrastructure and the capacity of local power lines to handle additional energy input would also be crucial factors in determining the most suitable locations for solar farms in the vicinity of Villars-les-Dombes.

France solar PV Stats as a country

This means that 2.80% of France's total energy as a country comes from solar PV (that's 30th in the world). Each year France is generating 218 Watts from solar PV per capita (France ranks 23rd in the world for solar PV Watts generated per capita). [source]

Are there incentives for businesses to install solar in France?

Yes, there are several incentives for businesses wanting to install solar energy in France. The French government offers a range of financial incentives and tax credits to encourage businesses to invest in renewable energy sources such as solar power.
