Solar PV Analysis of Serris, France
Serris, France, located at 48.8505°N, 2.7817°E, presents a mixed picture for solar energy generation throughout the year. This location in the Northern Temperate Zone experiences significant seasonal variations in solar output, which impacts the overall efficiency of photovoltaic (PV) systems.
Seasonal Solar Performance
The solar energy production in Serris follows a predictable pattern aligned with the changing seasons:
Summer stands out as the most productive period, with an average daily output of 5.56 kWh per kW of installed solar capacity. Spring follows closely behind, generating 4.97 kWh/day. These seasons offer the best conditions for solar energy harvesting, with longer days and higher sun angles.
Autumn sees a significant drop in production, averaging 2.89 kWh/day. Winter presents the greatest challenge, with output plummeting to just 1.34 kWh/day per kW installed. This stark contrast highlights the importance of considering seasonal variations when planning solar installations in Serris.
Optimal Panel Positioning
To maximize year-round solar energy production in Serris, fixed solar panels should be tilted at a 42-degree angle facing south. This orientation helps balance the seasonal variations, capturing more sunlight during the less productive winter months while still performing well in summer.
Environmental Considerations
While Serris doesn't face extreme environmental challenges, there are factors that could impact solar production:
- Cloud cover: The region experiences frequent overcast conditions, particularly in autumn and winter, which can reduce solar output.
- Snow: Occasional winter snowfall can temporarily cover panels, though this is generally not a major concern.
To mitigate these issues, consider installing panels with anti-soiling coatings to reduce snow adherence and improve performance in cloudy conditions. Additionally, implementing a regular cleaning schedule can help maintain optimal efficiency year-round.
In conclusion, while Serris isn't an ideal location for consistent year-round solar production, it still offers significant potential, especially during spring and summer. With proper panel positioning and maintenance, solar PV systems can provide a valuable contribution to the local energy mix, particularly as part of a diversified renewable energy strategy.

Solar output per kW of installed solar PV by season in Serris
Seasonal solar PV output for Latitude: 48.8505, Longitude: 2.7817 (Serris, 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 Serris, France
To maximize your solar PV system's energy output in Serris, France (Lat/Long 48.8505, 2.7817) 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 Serris, 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 Serris, 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 Serris, 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 Serris, 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 Serris, France
The area around Serris, France, is characterized by relatively flat terrain typical of the Île-de-France region. This part of France is known for its gently rolling plains and low-lying landscapes, with only subtle variations in elevation. The topography is largely shaped by the Seine and Marne river basins, which have created a predominantly level surface over thousands of years.
Serris itself is situated in the eastern suburbs of Paris, in an area known as Marne-la-Vallée. The land here is primarily composed of fertile agricultural plains interspersed with small forests and urban developments. The elevation in this region typically ranges from about 80 to 120 meters above sea level, with very gradual changes in altitude across the landscape.
As for areas nearby that would be most suited to large-scale solar PV (photovoltaic) installations, several factors need to be considered. The ideal locations would be open, relatively flat areas with minimal shading from trees or buildings, and good access to existing electrical infrastructure. Given these criteria, some of the agricultural lands surrounding Serris could potentially be suitable for solar farms.
Specifically, the open fields to the east and southeast of Serris, extending towards the communes of Bailly-Romainvilliers and Magny-le-Hongre, might offer promising sites for solar PV development. These areas benefit from the region's generally flat terrain and have fewer urban obstacles that could cast shadows on solar panels.
However, it's important to note that the Île-de-France region, including the area around Serris, is not known for having the highest levels of solar irradiance in France. The southern regions of the country typically receive more intense and consistent sunlight throughout the year. Additionally, the region's valuable agricultural land and proximity to urban areas might present challenges in terms of land use regulations and community acceptance for large-scale solar projects.
Any potential solar PV development in this area would need to carefully balance energy production goals with preservation of agricultural resources and consideration of local land use priorities. Environmental impact assessments and community consultations would be crucial steps in identifying the most appropriate locations for such projects.
