Solar PV Analysis of Meudon, France
Meudon, France, situated in the Northern Temperate Zone, presents a mixed picture for solar energy generation throughout the year. This location experiences significant seasonal variations in solar output, which impacts the overall efficiency of photovoltaic (PV) systems.
Seasonal Solar Performance
Summer stands out as the most productive season, with an impressive 5.56 kWh per day for each kilowatt of installed solar capacity. Spring follows closely behind, generating 4.97 kWh/day. However, the output drops considerably during autumn, yielding 2.89 kWh/day, and plummets to a mere 1.34 kWh/day in winter.
These figures highlight the substantial difference between the peak and trough of solar production in Meudon. The summer months offer ideal conditions for solar energy generation, with long days and typically clearer skies. Spring also provides favorable conditions, making it the second-best season for solar output.
Optimizing Panel Installation
To maximize year-round solar production in Meudon, fixed panels should be tilted at a 42-degree angle facing south. This optimal angle takes into account the location's latitude and the sun's position throughout the year, ensuring the best possible exposure to sunlight across all seasons.
Environmental and Weather Considerations
While Meudon's climate is generally conducive to solar energy production, there are some factors that could potentially impact efficiency:
- Cloud cover: Meudon experiences significant cloud cover, especially during autumn and winter, which can reduce solar output.
- Precipitation: Rainfall and occasional snow can temporarily decrease panel efficiency.
To mitigate these issues, consider installing high-efficiency panels that perform well in low-light conditions. Regular cleaning and maintenance of panels can also help offset the impact of precipitation and dust accumulation. Additionally, incorporating a battery storage system can help balance out the seasonal variations in energy production, ensuring a more consistent power supply throughout the year.
In conclusion, while Meudon's location presents challenges for year-round solar energy production, particularly in winter, the substantial output during spring and summer makes it a viable option for solar PV installation. With proper planning and optimization, solar energy can be a valuable component of the local energy mix.

Solar output per kW of installed solar PV by season in Meudon
Seasonal solar PV output for Latitude: 48.8088, Longitude: 2.2296 (Meudon, 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 Meudon, France
To maximize your solar PV system's energy output in Meudon, France (Lat/Long 48.8088, 2.2296) 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 Meudon, 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 Meudon, 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 Meudon, 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 Meudon, 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 Meudon, France
Meudon, France, is located in the southwestern suburbs of Paris, situated on a hill that overlooks the capital city. The topography of the area is characterized by gentle slopes and elevated terrain, with the highest point reaching about 179 meters (587 feet) above sea level. This hilly landscape is part of the larger Île-de-France region, which generally consists of rolling hills and plateaus interspersed with river valleys.
The area around Meudon features a mix of urban development and green spaces. To the east, the land slopes down towards the Seine River, while to the west, it gradually rises towards the Forêt de Meudon, a large wooded area. The town itself is built on varying elevations, with some neighborhoods situated on steeper inclines than others.
When considering areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, several factors come into play. Ideal locations would have relatively flat or gently sloping terrain, minimal shading from trees or buildings, and good exposure to sunlight throughout the day. Given these criteria, some potential areas for solar PV development might include:
1. The outskirts of the Forêt de Meudon: While the forest itself is protected, there may be cleared areas or fields on its periphery that could accommodate solar installations without significant environmental impact.
2. Former industrial sites or brownfields: These areas, if present in the region, often provide large, open spaces suitable for solar farms and have the added benefit of repurposing previously developed land.
3. Agricultural land to the southwest: The terrain becomes more open and less urbanized as you move away from Paris, potentially offering suitable sites for solar development, although this would need to be balanced with agricultural needs.
4. Rooftops of large commercial or industrial buildings: While not strictly "topography," the flat roofs of warehouses, shopping centers, or other large structures in the area could provide significant space for solar panel installation.
It's important to note that any large-scale solar PV project would require detailed site assessments, environmental impact studies, and compliance with local regulations. The proximity to Paris and the largely developed nature of the region may limit options for extensive ground-mounted solar farms, making rooftop and smaller-scale installations more practical in this area.
