Aigues-Mortes, Occitanie, France offers reasonably good conditions for solar energy generation, though with significant seasonal variation typical of its Mediterranean climate in the Northern Temperate Zone. The location shows strong summer performance with excellent spring output, but faces challenges during the darker winter months.

Seasonal Solar Performance

The solar energy output at Aigues-Mortes varies dramatically throughout the year. Summer delivers the peak performance at 7.55kWh per day per kW of installed capacity, making it an excellent time for solar generation. Spring also performs well with 5.94kWh daily output, providing strong energy production during the shoulder season. Autumn sees a notable decline to 3.54kWh per day, while winter presents the most challenging period with just 2.05kWh daily output per kW installed. This winter figure represents less than one-third of summer production, highlighting the seasonal dependency of solar generation at this latitude.

Optimal Installation Configuration

For maximum year-round energy production at Aigues-Mortes, Occitanie, solar panels should be installed at a fixed tilt angle of 37 degrees facing south. This angle has been calculated to optimize total annual output by accounting for the sun's changing position throughout the year and weighting the angles based on actual solar irradiance data.

Local Environmental Factors

Several environmental factors at Aigues-Mortes could impact solar panel performance and require consideration during installation:

• Salt air exposure: The coastal Mediterranean location means panels face constant exposure to salt-laden air, which can cause corrosion and reduce efficiency over time
• Mistral winds: This region experiences strong, dry winds that can carry dust and debris, potentially covering panels and reducing output
• Mediterranean dust: Seasonal dust from North Africa can settle on panels, creating a film that blocks sunlight
• High summer temperatures: Intense summer heat can actually reduce panel efficiency despite the high solar irradiance

Preventative Measures

To maximize solar energy production despite these challenges, several installation strategies should be implemented:

• Corrosion-resistant materials: Use marine-grade aluminum frames and stainless steel mounting hardware to withstand salt air exposure
• Enhanced cleaning systems: Install automatic cleaning systems or plan for frequent manual cleaning to remove salt, dust, and debris
• Robust mounting: Design mounting systems to withstand strong Mistral winds with proper structural reinforcement
• Ventilation spacing: Allow adequate air circulation behind panels to prevent overheating during intense summer periods
• Protective coatings: Consider anti-soiling coatings on panel surfaces to reduce dust and salt accumulation

Overall, Aigues-Mortes represents a moderately favorable location for solar PV installation, with excellent summer and good spring production offsetting the lower winter output. Proper installation techniques addressing local environmental factors can help ensure optimal long-term performance.

Solar output per kW of installed solar PV by season in Aigues-Mortes

Seasonal solar PV output for Latitude: 43.5671, Longitude: 4.1874 (Aigues-Mortes, 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 37° South in Aigues-Mortes, France

To maximize your solar PV system's energy output in Aigues-Mortes, France (Lat/Long 43.5671, 4.1874) throughout the year, you should tilt your panels at an angle of 37° 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 Aigues-Mortes, 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 Aigues-Mortes, France. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 37° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
27° South in Summer	48° South in Autumn	58° South in Winter	36° 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 Aigues-Mortes, 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 Aigues-Mortes, France.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Aigues-Mortes, France

Topography and Landscape

Aigues-Mortes sits in the heart of the Camargue region in southern France, positioned within a remarkably flat and expansive landscape that stretches toward the Mediterranean Sea. This medieval fortified town is surrounded by vast salt marshes, lagoons, and wetlands that characterize the Rhône River delta. The terrain is exceptionally low-lying, with much of the surrounding area at or near sea level, creating an almost pancake-flat topography that extends for kilometers in every direction. The landscape immediately around Aigues-Mortes consists primarily of salt pans, shallow lagoons, and marshy areas that have been shaped by centuries of salt production and natural sedimentation from the Rhône. These wetlands are interspersed with slightly elevated areas of sandy soil and sparse vegetation typical of Mediterranean coastal plains. The absence of hills, mountains, or significant elevation changes creates unobstructed views across the countryside, with the horizon often appearing as a distant line where land meets sky.

Optimal Areas for Large-Scale Solar Development

The flat topography surrounding Aigues-Mortes presents excellent opportunities for large-scale solar photovoltaic installations, though careful site selection is essential due to the sensitive wetland environment. The most suitable areas would be the slightly elevated sandy plains and former agricultural lands that lie to the north and northwest of the town, where the ground is more stable and less prone to seasonal flooding. These elevated areas, though still relatively flat, offer better drainage and soil stability compared to the active salt marshes and lagoons. The consistent flatness eliminates concerns about shading from topographical features and allows for optimal panel orientation and spacing. The open landscape also provides excellent access for construction and maintenance vehicles, which is crucial for large-scale solar projects. Areas that should be avoided include the active salt pans, protected wetlands, and zones designated as important bird habitats within the Camargue Natural Regional Park. The seasonal lagoons and marshes, while flat, present challenges due to their ecological sensitivity and potential water table fluctuations. Instead, the best locations would be on the periphery of the wetland areas, where the land transitions to more stable, well-drained terrain while still maintaining the advantageous flat topography that makes this region so suitable for solar energy generation.
