Solar PV Analysis of Versailles, France
Versailles, France, located at 48.8027° N, 2.1373° E, presents a mixed picture for solar energy generation throughout the year. Situated in the Northern Temperate Zone, this historic city experiences significant seasonal variations in solar output.
Seasonal Solar Performance
Summer stands out as the most productive season for solar energy in Versailles, 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 ideal conditions for maximizing solar energy production.
However, the picture changes dramatically during the colder months. Autumn sees a substantial drop in output to 2.89 kWh/day, while winter performance plummets to a mere 1.34 kWh/day. This stark contrast highlights the challenges of relying solely on solar power in Versailles year-round.
Optimizing Installation
To maximize year-round solar energy production in Versailles, fixed solar panels should be installed at a tilt angle of 42 degrees facing south. This optimal angle helps capture the most sunlight throughout the year, balancing the high summer sun with the lower winter sun angle.
Environmental Considerations
While Versailles doesn't face extreme environmental challenges for solar production, there are some factors to consider:
- Cloud cover: The region experiences frequent overcast days, particularly in winter, which can reduce solar output.
- Rain and humidity: Versailles has a relatively high annual rainfall, which can affect panel efficiency.
To mitigate these issues, consider using high-efficiency panels designed to perform well in low-light conditions. Regular cleaning and maintenance of panels can also help offset the impact of rain and humidity. Additionally, implementing a hybrid system that combines solar with other renewable energy sources could provide more consistent year-round power generation.
In conclusion, while Versailles offers excellent solar potential during spring and summer, the significant drop in autumn and winter output means that solar PV alone may not be sufficient for year-round energy needs. However, with proper installation and supplementary energy sources, solar can still play a valuable role in the city's energy mix.
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 Versailles
Seasonal solar PV output for Latitude: 48.8027, Longitude: 2.1373 (Versailles, 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 Versailles, France
To maximize your solar PV system's energy output in Versailles, France (Lat/Long 48.8027, 2.1373) 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 Versailles, 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 Versailles, 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 Versailles, 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 Versailles, 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 Versailles, France
The topography around Versailles, France is characterized by gently rolling hills and plateaus, typical of the Île-de-France region. The area is part of the Paris Basin, a large sedimentary basin that forms a relatively flat landscape with subtle variations in elevation. Versailles itself sits on a slight plateau, with an average elevation of about 130 meters (427 feet) above sea level.
To the west and southwest of Versailles, the terrain becomes slightly more undulating as it transitions into the forested areas of the Rambouillet Forest. This area features small valleys and hills, with elevations ranging from 100 to 180 meters (328 to 591 feet). To the east, the land gradually slopes down towards Paris and the Seine River valley.
The immediate surroundings of Versailles include a mix of urban areas, parks, and agricultural land. The famous Gardens of Versailles, with their meticulously designed landscape, occupy a significant area to the west of the palace.
Areas Suitable for Large-Scale Solar PV
When considering locations for large-scale solar photovoltaic (PV) installations near Versailles, several factors need to be taken into account, including available land, sun exposure, and proximity to existing infrastructure. Based on these considerations, the following areas might be most suitable:
1. Agricultural lands to the southwest of Versailles: The relatively flat agricultural areas between Versailles and Rambouillet could potentially accommodate large-scale solar installations. These areas benefit from good sun exposure and are away from densely populated urban centers.
2. Former industrial sites or brownfields: Any abandoned industrial areas or brownfields in the region could be repurposed for solar energy production. These sites often have the advantage of existing infrastructure connections.
3. Areas along major transportation corridors: Land adjacent to highways or railway lines, which is often less suitable for other uses, could be considered for solar PV installations. The A12 and N12 highways running southwest from Versailles might offer such opportunities.
4. Plateau areas to the south: The slightly elevated plateau areas to the south of Versailles, towards the communes of Toussus-le-Noble and Châteaufort, could provide good locations for solar farms due to their relatively flat terrain and open landscapes.
It's important to note that any large-scale solar PV project in this area would need to carefully consider environmental impacts, agricultural land preservation, and the region's rich cultural heritage. The proximity to Versailles Palace and its gardens, a UNESCO World Heritage site, would likely impose additional constraints on the siting of such installations.
