Les Mureaux, 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 output, which directly impact the efficiency and effectiveness of solar installations.
Seasonal Solar Performance
Summer stands out as the peak season for solar energy production in Les Mureaux, with an impressive daily output of 5.57 kWh per kW of installed solar capacity. Spring follows closely behind, generating 5.09 kWh/day. These seasons offer ideal conditions for maximizing solar energy production, with longer daylight hours and generally clearer skies.
However, the picture changes dramatically during the colder months. Autumn sees a substantial drop in output to 2.92 kWh/day, while winter performance plummets to a mere 1.33 kWh/day. This stark contrast highlights the challenges of year-round solar energy reliance in this location.
Optimizing Solar Installation
To maximize year-round solar energy production in Les Mureaux, fixed solar panels should be tilted at an angle of 42 degrees facing South. This optimal angle helps capture the most sunlight throughout the year, balancing the varying sun positions across seasons.
Environmental and Weather Factors
Several factors can impede solar production in Les Mureaux:
- Cloud cover: The region experiences frequent cloudy days, especially in autumn and winter, which can significantly reduce solar output.
- Short winter days: The limited daylight hours during winter months contribute to the low solar production in this season.
To mitigate these challenges, consider implementing these preventative measures:
- Use high-efficiency solar panels that perform better in low-light conditions.
- Install a solar tracking system to maximize exposure to available sunlight.
- Regularly clean panels to prevent dust and debris accumulation, which can be more prevalent in cloudy, damp conditions.
While Les Mureaux offers excellent solar potential during spring and summer, the significant drop in autumn and winter output means that supplementary energy sources or robust energy storage solutions should be considered for year-round energy reliability.

Solar output per kW of installed solar PV by season in Les Mureaux
Seasonal solar PV output for Latitude: 48.9909, Longitude: 1.9049 (Les Mureaux, 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 Les Mureaux, France
To maximize your solar PV system's energy output in Les Mureaux, France (Lat/Long 48.9909, 1.9049) 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 Les Mureaux, 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 Les Mureaux, 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 |
|---|---|---|---|
| 33° South in Summer | 52° South in Autumn | 63° 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 Les Mureaux, 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 Les Mureaux, 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 Les Mureaux, France
Les Mureaux, located in north-central France, sits within a diverse topographical landscape characterized by gentle undulations and river valleys. The town itself is situated on the left bank of the Seine River, which meanders through the region, creating a picturesque setting. The immediate area around Les Mureaux features a mix of urban development and open spaces, with the terrain gradually rising as one moves away from the river. To the north and east of Les Mureaux, the land gently slopes upward, forming low hills and plateaus. These areas are predominantly rural, with a patchwork of agricultural fields and small woodlands. The elevation change is subtle, rarely exceeding 100 meters above the river level. This gradual incline continues for several kilometers before reaching the more pronounced hills of the Vexin français natural regional park. South of Les Mureaux, across the Seine, the landscape is similarly varied. The river's floodplain gives way to slightly higher ground, creating a series of terraces that have been largely developed for residential and industrial use. Further south, the terrain becomes more pronounced, with steeper hills and valleys characteristic of the Yvelines department.
Potential Areas for Large-Scale Solar PV
When considering areas suitable for large-scale solar photovoltaic (PV) installations near Les Mureaux, several factors come into play. Ideal locations would have relatively flat or gently sloping terrain, good sun exposure, and minimal environmental or cultural constraints. The agricultural areas to the north and northeast of Les Mureaux present promising opportunities for solar PV development. These open fields offer large, unobstructed spaces with favorable sun exposure. The gentle slopes in this direction could potentially enhance solar panel efficiency by allowing for optimal positioning towards the sun. Another area of interest lies to the southeast of Les Mureaux, where there are expanses of open land between smaller settlements. These areas, while more developed than those to the north, still offer potential sites for solar farms, particularly on less productive agricultural land or brownfield sites. It's important to note that any large-scale solar development would need to carefully consider local zoning regulations, environmental impacts, and the preservation of agricultural land. The proximity to the Seine River and its associated ecosystems would also require thorough environmental assessments before any project could proceed. In conclusion, while the topography around Les Mureaux is generally favorable for solar PV installations, the most suitable areas are likely to be found in the gently sloping agricultural lands to the north and northeast, as well as select locations to the southeast. These areas combine the necessary physical characteristics with the potential for minimal conflict with existing land uses and natural habitats.France solar PV Stats as a country
