Biganos, France offers reasonably good conditions for year-round solar energy generation, though with significant seasonal variation typical of its Northern Temperate Zone location at latitude 44.6389, longitude -0.9776.

Seasonal Solar Performance

The location shows strong seasonal contrasts in solar energy production. Summer delivers the highest output at 6.18 kWh per day per kW of installed solar capacity, making it the peak season for energy generation. Spring follows as the second-best performing season with 5.36 kWh per day per kW, offering excellent production levels that nearly match summer performance. Autumn sees a notable decline to 3.21 kWh per day per kW, while winter represents the most challenging period with only 1.76 kWh per day per kW of production. This winter figure is quite low and typical of northern European locations during the darker months. For optimal year-round energy capture, solar panels should be installed at a fixed tilt angle of 38 degrees facing south. This angle maximizes total annual production by accounting for the sun's varying position throughout the year and weighting for the solar irradiance potential at different times.

Local Environmental Challenges

Several environmental factors in the Biganos area could potentially impact solar energy production:

• Atlantic coastal humidity and salt air exposure, which can cause corrosion and reduce panel efficiency over time
• Frequent cloud cover and overcast conditions typical of the southwestern French climate
• Pine pollen from the surrounding Landes forest, which can accumulate on panels and block sunlight
• Occasional severe Atlantic storms that may damage installations

Preventative Installation Measures

To maximize energy production despite these challenges, several installation strategies should be considered. Using marine-grade mounting hardware and corrosion-resistant materials helps combat the effects of salt air exposure. Regular cleaning schedules become particularly important during spring pollen season and after storms to maintain optimal light transmission. Installing panels with adequate spacing allows for better air circulation, reducing moisture buildup and improving cooling efficiency. Storm-resistant mounting systems designed for high wind loads provide essential protection during severe weather events. Additionally, anti-reflective coatings and hydrophobic treatments on panel surfaces can help shed water and reduce soiling accumulation. Despite the seasonal variation and environmental challenges, Biganos remains a viable location for solar energy generation, particularly during the highly productive spring and summer months when output is substantial.

Solar output per kW of installed solar PV by season in Biganos

Seasonal solar PV output for Latitude: 44.6389, Longitude: -0.9776 (Biganos, 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 38° South in Biganos, France

To maximize your solar PV system's energy output in Biganos, France (Lat/Long 44.6389, -0.9776) throughout the year, you should tilt your panels at an angle of 38° 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 Biganos, 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 Biganos, France. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 38° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
28° South in Summer	48° South in Autumn	59° South in Winter	37° 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 Biganos, 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 Biganos, 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 Biganos, France

Topography Around Biganos

Biganos sits in the heart of the Gironde department in southwestern France, positioned within the distinctive landscape of the Landes de Gascogne region. The terrain around this commune is characteristically flat to gently undulating, with elevations rarely exceeding 50 meters above sea level. This low-lying topography forms part of the vast coastal plain that extends along France's Atlantic seaboard. The area is dominated by the extensive Landes forest, one of Europe's largest artificial forests, which was planted in the 19th century to stabilize the sandy soils and drain the previously marshy terrain. The landscape consists primarily of maritime pine plantations interspersed with heathland, creating a relatively uniform canopy across much of the region. Small clearings and agricultural parcels break up the forested expanse, particularly closer to settlements. Water features play a significant role in shaping the local topography. The Leyre River meanders through the area, creating subtle valleys and wetland zones. Several smaller streams and drainage channels crisscross the landscape, evidence of ongoing efforts to manage water levels in this naturally low-lying region. These waterways have carved gentle depressions in the sandy substrate, creating the most pronounced topographical variation in an otherwise remarkably flat terrain.

Optimal Areas for Large-Scale Solar Development

The relatively flat topography around Biganos presents excellent opportunities for large-scale solar photovoltaic installations. The most suitable locations would be the cleared agricultural areas and open heathland spaces, particularly those positioned on the gentle slopes that provide natural drainage while maintaining good southern exposure. Former agricultural lands that have been taken out of production represent prime candidates for solar development. These areas typically feature minimal elevation changes, established access routes, and cleared vegetation, significantly reducing site preparation costs. The sandy soils common throughout the region provide stable foundations for solar mounting systems while allowing for efficient drainage. Open heathland areas, particularly those on slightly elevated ground, offer another excellent option for solar installations. These locations benefit from reduced shading concerns and often feature natural clearings large enough to accommodate substantial solar arrays. The elevated positions, while modest in height, provide better air circulation around solar panels and reduce the risk of flooding during wet periods. Areas near existing infrastructure corridors, such as those adjacent to major roads or power transmission lines, present additional advantages for solar development. The flat terrain makes construction access straightforward, while proximity to electrical infrastructure can reduce connection costs and complexity. The extensive forested areas, while abundant, would require significant clearing and may face environmental restrictions due to their ecological importance and role in regional land management. However, forest clearings created for other purposes or areas affected by natural disturbances could potentially be repurposed for solar installations, provided they receive adequate sunlight exposure throughout the day.
