Solar PV Analysis of Melun, France
Melun, France, situated at coordinates 48.5478, 2.6568, presents a varied landscape for solar energy generation throughout the year. This location in the Northern Temperate Zone experiences significant seasonal fluctuations in solar output, which impacts the efficiency of photovoltaic (PV) systems.
Seasonal Solar Performance
Solar energy production in Melun reaches its peak during the summer months, with an impressive daily output of 5.56 kWh per kW of installed capacity. Spring follows closely behind, generating 4.97 kWh/day. However, autumn sees a considerable drop to 2.89 kWh/day, while winter experiences the lowest production at just 1.34 kWh/day.
These figures highlight that the most ideal times for solar energy generation in Melun are from late spring through early autumn. During these periods, longer daylight hours and higher sun angles contribute to increased solar panel efficiency.
Optimizing Solar Panel Installation
To maximize year-round solar energy production in Melun, fixed solar panels should be installed at a tilt angle of 42 degrees facing south. This optimal angle takes into account the location's latitude and seasonal sun paths, ensuring the best possible exposure throughout the year.
Environmental and Weather Considerations
While Melun's climate is generally favorable for solar energy production, there are some factors that could potentially impact efficiency:
- Cloud cover: Melun experiences frequent cloud cover, especially during autumn and winter, which can reduce solar output.
- Precipitation: The area receives regular rainfall, which may temporarily decrease panel efficiency.
To mitigate these challenges, consider implementing the following measures:
- Use high-efficiency solar panels designed to perform well in diffuse light conditions.
- Install a robust cleaning system or schedule regular maintenance to remove dirt and debris that may accumulate on panels.
- Consider adding a solar tracking system to maximize energy capture during periods of clear sky.
By addressing these factors and optimizing panel placement, Melun can still harness significant solar energy potential, particularly during the more productive months of the year.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Melun
Seasonal solar PV output for Latitude: 48.5478, Longitude: 2.6568 (Melun, 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 Melun, France
To maximize your solar PV system's energy output in Melun, France (Lat/Long 48.5478, 2.6568) 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 Melun, 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 Melun, 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 Melun, 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 Melun, 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 Melun, France
The area around Melun, France, is characterized by a gently rolling landscape typical of the Île-de-France region. Situated in the Seine-et-Marne department, Melun is located on the banks of the Seine River, which meanders through the area, creating a picturesque valley. The terrain is predominantly low-lying, with subtle hills and plateaus interspersed throughout the countryside.
The topography of the region is largely shaped by the Seine River and its tributaries. The river valley is relatively wide and flat, flanked by gradual slopes rising to higher ground on either side. These elevated areas are generally not very steep or mountainous but rather consist of modest hills and plateaus that offer pleasant views of the surrounding landscape.
To the north and east of Melun, you'll find the expansive Brie plateau, a vast agricultural area known for its fertile soils. This plateau is characterized by open fields, scattered woodlands, and gentle undulations in the terrain. To the south and west, the landscape becomes slightly more varied, with a mix of forests, farmland, and small valleys created by tributary streams of the Seine.
Regarding areas nearby that would be most suited to large-scale solar PV (photovoltaic) installations, several factors should be considered:
The Brie plateau to the north and east of Melun offers promising potential for solar farms. Its relatively flat terrain and open agricultural lands provide ample space and good sun exposure. Many of these areas are already used for farming, which could potentially be combined with solar installations in an agrivoltaic approach.
Some of the gently sloping hillsides facing south or southeast could also be suitable locations for solar panels, as they would receive optimal sunlight throughout the day. However, care should be taken to avoid areas of significant natural or cultural importance.
It's worth noting that while the region around Melun has potential for solar energy development, any large-scale projects would need to be carefully planned to balance energy production with preservation of the area's agricultural heritage and natural beauty. Environmental impact assessments and community consultations would be crucial steps in identifying the most appropriate sites for solar PV installations in this region.
