Solar PV Analysis of Neuilly-sur-Seine, France
Neuilly-sur-Seine, France, situated in the Northern Temperate Zone, presents a mixed landscape for solar energy generation throughout the year. This location experiences significant seasonal variations in solar output, which directly impacts the efficiency of photovoltaic (PV) systems.
Seasonal Solar Performance
Summer stands out as the most productive season, with an impressive daily output of 5.56 kWh per kW of installed solar capacity. Spring follows closely behind, generating 4.97 kWh/day. However, the performance drops considerably during autumn, with 2.89 kWh/day, and reaches its lowest point in winter, producing only 1.34 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 variation is primarily due to the changing day length and sun angle throughout the year at this latitude.
Optimal Panel Positioning
To maximize year-round energy production, fixed solar panels in Neuilly-sur-Seine should be tilted at a 42-degree angle facing south. This optimal angle has been calculated to balance the seasonal variations and capture the most sunlight possible throughout the year.
Environmental and Weather Considerations
While Neuilly-sur-Seine doesn't face extreme weather conditions, there are factors that could impact solar production:
- Cloud cover: The region experiences frequent overcast days, especially in autumn and winter, which can significantly reduce solar output.
- Urban pollution: Being close to Paris, air pollution can sometimes create a haze that slightly diminishes solar efficiency.
To mitigate these factors, consider using high-efficiency panels that perform well in low-light conditions. Regular cleaning of the panels can also help maintain optimal performance by removing any accumulated dust or pollutants.
Conclusion
While Neuilly-sur-Seine may not be ideal for year-round solar energy production due to its significant seasonal variations, it still offers good potential, especially from spring through autumn. With proper panel positioning and maintenance, a solar PV system can provide substantial energy contributions, particularly during the longer, sunnier days of the year.
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 Neuilly-sur-Seine
Seasonal solar PV output for Latitude: 48.8871, Longitude: 2.2745 (Neuilly-sur-Seine, 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 Neuilly-sur-Seine, France
To maximize your solar PV system's energy output in Neuilly-sur-Seine, France (Lat/Long 48.8871, 2.2745) 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 Neuilly-sur-Seine, 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 Neuilly-sur-Seine, 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 | 52° 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 Neuilly-sur-Seine, 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 Neuilly-sur-Seine, 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 Neuilly-sur-Seine, France
Neuilly-sur-Seine is a suburb located just west of Paris, France. The topography of this area is generally flat to gently rolling, characteristic of the Paris Basin region. The town itself sits on the right bank of the River Seine, which forms its southern border. The elevation in Neuilly-sur-Seine is relatively low, typically ranging from about 30 to 40 meters (98 to 131 feet) above sea level.
The surrounding landscape is predominantly urban, with densely built areas extending in all directions. To the east lies Paris proper, while to the west, the terrain gradually rises towards the forested hills of Saint-Germain-en-Laye. North of Neuilly-sur-Seine, the land remains mostly flat as it stretches towards the suburban areas of Levallois-Perret and Clichy.
When considering areas nearby that might be suitable for large-scale solar PV (photovoltaic) installations, it's important to note that the immediate vicinity of Neuilly-sur-Seine is not ideal due to its urban density and lack of open spaces. However, moving further out from the city center, there are some potential locations that could be more appropriate:
The plains to the north and northwest of Paris, particularly in the Val-d'Oise department, offer more open terrain that could potentially accommodate solar farms. These areas have less urban development and more agricultural land that might be repurposed for renewable energy projects.
Another possibility lies to the southeast of Paris in the Seine-et-Marne department. This region has more expansive rural areas with flat or gently sloping terrain that could be suitable for large-scale solar installations.
It's worth noting that while these areas may have more favorable topography for solar PV, any large-scale installation would need to carefully consider factors such as local zoning laws, environmental impact, and grid connection capabilities. Additionally, France's commitment to preserving agricultural land may limit the availability of suitable sites for solar farms in the broader Île-de-France region.
France solar PV Stats as a country
France ranks 11th in the world for cumulative solar PV capacity, with 14,718 total MW's of solar PV installed. 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.
