La Celle-Saint-Cloud, France, situated in the Northern Temperate Zone, presents a mixed picture for solar PV energy generation throughout the year. This location experiences significant seasonal variations in solar energy production, which impact its overall suitability for solar power installations.
Seasonal Solar Energy Production
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. These seasons offer excellent conditions for solar energy harvesting, with longer daylight hours and generally clearer skies.
Autumn sees a considerable drop in production, yielding 2.89 kWh/day. The most challenging season is winter, with a significantly reduced output of just 1.34 kWh/day. This stark contrast highlights the impact of shorter days and less favorable weather conditions during the colder months.
Optimal Panel Positioning
To maximize year-round solar energy production in La Celle-Saint-Cloud, fixed solar panels should be tilted at a 42-degree angle facing south. This optimal angle ensures the best possible exposure to sunlight throughout the year, balancing the varying sun positions across seasons.
Environmental and Weather Considerations
While La Celle-Saint-Cloud's climate is generally favorable for solar energy production, there are some factors that could potentially impact efficiency:
- Cloud cover: The region experiences cloudy days, particularly in autumn and winter, which can reduce solar panel efficiency.
- Rain and snow: Precipitation, more common in colder months, can temporarily decrease energy production.
To mitigate these issues, consider implementing the following measures:
- Use high-efficiency panels designed to perform well in low-light conditions.
- Install a robust cleaning system or schedule regular maintenance to remove snow and debris.
- Implement micro-inverters or power optimizers to minimize the impact of partial shading on overall system performance.
In conclusion, while La Celle-Saint-Cloud experiences significant seasonal variations in solar energy production, it remains a viable location for solar PV installations. The substantial output during spring and summer months can help offset the reduced production in autumn and winter. With proper planning and the implementation of appropriate technologies, solar energy can be a valuable renewable resource in this French commune.

Solar output per kW of installed solar PV by season in La Celle-Saint-Cloud
Seasonal solar PV output for Latitude: 48.8527, Longitude: 2.1381 (La Celle-Saint-Cloud, 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 La Celle-Saint-Cloud, France
To maximize your solar PV system's energy output in La Celle-Saint-Cloud, France (Lat/Long 48.8527, 2.1381) 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 La Celle-Saint-Cloud, 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 La Celle-Saint-Cloud, 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 La Celle-Saint-Cloud, 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 La Celle-Saint-Cloud, 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 La Celle-Saint-Cloud, France
La Celle-Saint-Cloud is located in the western suburbs of Paris, France. The topography of this area is characterized by gently rolling hills and plateaus, typical of the Île-de-France region. The landscape is a mix of urban development and green spaces, with elevations ranging from about 100 to 180 meters above sea level.
The town itself is situated on a slight elevation, offering views of the surrounding area. To the west and southwest, the terrain gradually slopes down towards the Seine River valley. The famous Palace of Versailles is located a short distance to the south, in an area with similar topographical features.
To the east, the land becomes more urbanized as it approaches Paris, with a generally flatter profile. The northern parts of La Celle-Saint-Cloud and its surroundings include some wooded areas and parks, providing a green belt that separates it from neighboring communities.
Regarding large-scale solar PV installations, the immediate vicinity of La Celle-Saint-Cloud may not be ideal due to its suburban nature and the presence of protected green spaces. However, some nearby areas that could potentially be suitable for solar projects include:
- The agricultural plains to the west and southwest of La Celle-Saint-Cloud, extending towards the towns of Feucherolles and Saint-Nom-la-Bretèche. These areas offer relatively flat terrain and open spaces that could accommodate large solar arrays.
- The less densely populated regions to the northwest, in the direction of Chambourcy and Aigremont, where there are some open fields and gentle slopes that receive good sun exposure.
- Certain industrial or commercial zones on the outskirts of nearby towns, such as Le Pecq or Louveciennes, which might have large roof spaces or unused land parcels suitable for solar installations.
It's important to note that any large-scale solar PV project in this region would need to carefully consider local zoning laws, environmental regulations, and the preservation of the area's cultural and natural heritage. The proximity to Paris and Versailles means that development in this region is often strictly controlled to maintain its historical and aesthetic character.
