Agde, Occitanie, a town in southern France, presents a mixed picture for year-round solar energy generation. Located at 43.3155°N, 3.4704°E in the Northern Temperate Zone, this Mediterranean coastal town experiences significant seasonal variations in solar energy production.
Seasonal Solar Output
Solar panel performance in Agde fluctuates considerably throughout the year. Summer stands out as the most productive season, with an impressive daily output of 7.12 kWh per kW of installed solar capacity. Spring follows as the second-best season, generating 5.58 kWh/day. However, autumn and winter see a substantial drop in production, with 3.37 kWh/day and 1.91 kWh/day respectively.
Optimal Times for Solar Generation
The period from late spring through early autumn is ideal for solar energy production in Agde. During these months, longer days and higher sun angles contribute to increased solar panel efficiency. Conversely, the winter months, particularly December and January, are the least favorable due to shorter days and lower sun angles.
Panel Tilt Optimization
To maximize year-round solar energy production in Agde, Occitanie, fixed solar panels should be installed at a tilt angle of 37 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, balancing the varying sun angles across seasons.
Environmental and Weather Considerations
While Agde's climate is generally favorable for solar energy production, there are some factors that could potentially impact efficiency:
- Coastal humidity and salt spray: Being close to the Mediterranean, salt accumulation on panels could reduce efficiency over time.
- Occasional strong winds: The region experiences periodic strong winds, which could pose a risk to panel installations if not properly secured.
To mitigate these issues, regular cleaning of panels to remove salt deposits is recommended. Additionally, using corrosion-resistant materials and ensuring robust mounting systems can help protect against wind damage and extend the lifespan of the solar installation.
Overall, while Agde's location presents some challenges, particularly during the winter months, it remains a viable option for solar energy production with proper planning and maintenance.

Solar output per kW of installed solar PV by season in Agde
Seasonal solar PV output for Latitude: 43.3155, Longitude: 3.4704 (Agde, 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 Agde, France
To maximize your solar PV system's energy output in Agde, France (Lat/Long 43.3155, 3.4704) 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 Agde, 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 Agde, 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 | 47° 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 Agde, 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 Agde, 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 Agde, France
The area surrounding Agde, France, is characterized by a diverse and picturesque topography that reflects its coastal Mediterranean location. Situated at the confluence of the Hérault River and the Mediterranean Sea, Agde is nestled in a relatively flat coastal plain that gradually rises into gently rolling hills as one moves inland. To the east and northeast of Agde, the landscape is dominated by expansive wetlands and lagoons, most notably the Étang de Thau, a large saltwater lagoon separated from the Mediterranean by a narrow strip of land. This area is known for its rich biodiversity and is home to numerous bird species. Moving westward and slightly inland from Agde, the terrain becomes more varied. Low hills and plateaus begin to emerge, creating a patchwork of agricultural lands, vineyards, and scattered woodlands. These gentle elevations rarely exceed 100 meters above sea level but provide a pleasant contrast to the flatness of the immediate coastal area.
Potential for Large-Scale Solar PV
When considering areas near Agde that would be most suitable for large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would combine favorable topography with minimal environmental impact and proximity to existing infrastructure. The gently sloping hills to the north and northwest of Agde present promising opportunities for solar PV development. These areas receive ample sunlight due to their southern exposure and lack of significant shading from higher elevations. The moderate slopes can actually be advantageous for solar panel placement, allowing for optimal angling towards the sun and reducing the risk of panels shading each other. Another potential area for solar PV development lies in the agricultural lands to the west and southwest of Agde. While care must be taken to balance energy production with food security, certain less productive agricultural plots could be repurposed for solar farms. These areas are generally flat or have very gentle slopes, which simplifies installation and maintenance of solar panels. It's important to note that the immediate coastal areas and wetlands around Agde are less suitable for large-scale solar installations due to their ecological sensitivity and potential for flooding. Additionally, the region's strong commitment to wine production means that prime vineyard land would likely be off-limits for solar development. Any large-scale solar PV project in the region would need to carefully consider local zoning regulations, grid connection possibilities, and the preservation of the area's natural and cultural heritage. With thoughtful planning, however, the diverse topography around Agde offers several promising locations for sustainable energy production through solar power.France solar PV Stats as a country
France ranks 11th in the world for cumulative solar PV capacity, with 14,718 total MW's of solar PV installed.
