Sucy-en-Brie, France, located in the Northern Temperate Zone, presents a mixed picture for year-round solar energy generation via photovoltaic (PV) panels. This location experiences significant seasonal variations in solar energy production, which is typical for its latitude.

Seasonal Solar Performance

Summer stands out as the most productive season, with an impressive 5.56 kWh per day for each kilowatt of installed solar capacity. Spring follows closely, generating 4.97 kWh/day. These seasons offer excellent conditions for solar energy production, with longer days and higher sun angles.

Autumn sees a noticeable decrease in output, dropping to 2.89 kWh/day. The most challenging season is winter, with production falling to just 1.34 kWh/day per kW installed. This significant drop is due to shorter days, lower sun angles, and typically cloudier weather.

Optimizing Solar Installation

To maximize year-round solar energy production in Sucy-en-Brie, fixed solar panels should be installed at a tilt angle of 42 degrees facing south. This angle is calculated to capture the most sunlight throughout the year, considering the location's latitude and seasonal sun positions.

Environmental and Weather Considerations

While Sucy-en-Brie doesn't face extreme environmental challenges for solar production, there are some factors to consider:

• Cloud cover: The region experiences frequent cloudy days, especially in winter, which can reduce solar output.
• Snow: Occasional winter snowfall can temporarily cover panels, though this is typically not a major issue.

To mitigate these factors, consider installing panels with anti-soiling coatings to reduce snow accumulation and ensure easy cleaning. Additionally, using microinverters or power optimizers can help maintain efficiency during partial shading conditions.

In conclusion, while Sucy-en-Brie isn't an ideal location for year-round solar production due to significant seasonal variations, it still offers good potential, especially from spring through autumn. With proper installation and maintenance, solar PV can be a viable renewable energy option in this area.

Solar output per kW of installed solar PV by season in Sucy-en-Brie

Seasonal solar PV output for Latitude: 48.7619, Longitude: 2.5408 (Sucy-en-Brie, 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 Sucy-en-Brie, France

To maximize your solar PV system's energy output in Sucy-en-Brie, France (Lat/Long 48.7619, 2.5408) 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 Sucy-en-Brie, 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 Sucy-en-Brie, 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 Sucy-en-Brie, 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 Sucy-en-Brie, 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 Sucy-en-Brie, France

The topography around Sucy-en-Brie, France, is characterized by gently rolling hills and shallow valleys typical of the Île-de-France region. Located in the southeastern suburbs of Paris, this area is part of the Paris Basin, a large sedimentary basin that has been shaped over millions of years. The landscape is predominantly low-lying, with subtle elevation changes that create a mix of flat areas and gentle slopes. Sucy-en-Brie itself sits on a slight elevation, with the land gradually sloping down towards the Marne River to the north. The surrounding area features a patchwork of urban developments, parks, and small pockets of woodland. To the south and east, the terrain becomes slightly more varied, with some more pronounced hills and valleys as you move towards the Brie plateau.

Potential for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The relatively flat terrain in many parts of the region surrounding Sucy-en-Brie could be advantageous for solar farms, as it would require minimal land preparation. Areas to the south and east of Sucy-en-Brie, where there is more open land and fewer urban developments, might be particularly suitable. These areas often have agricultural fields or fallow land that could potentially be repurposed for solar energy production. The gentle south-facing slopes found in some parts of this region could be ideal for maximizing solar exposure throughout the day. However, it's important to note that the Île-de-France region is densely populated, and land use is often tightly regulated. Any large-scale solar PV project would need to carefully consider environmental impact, local zoning laws, and potential conflicts with agricultural or residential land use. Additionally, the proximity to Paris might mean that some areas are protected for their cultural or historical significance, which could limit the available locations for solar farms. In conclusion, while the topography around Sucy-en-Brie is generally favorable for solar PV installations, the practical implementation of large-scale projects would require careful planning and consideration of various local factors beyond just the physical landscape.
