Levallois-Perret, France, situated in the Northern Temperate Zone, presents a mixed picture for solar PV energy generation. The location's potential for solar power production varies significantly throughout the year, with notable seasonal fluctuations.
Seasonal Solar Output
Summer stands out as the most productive season, with an impressive daily output of 5.51kWh per kW of installed solar capacity. Spring follows closely behind, generating 4.91kWh/day. However, the colder months see a substantial drop in production. Autumn yields 2.82kWh/day, while winter experiences a significant dip to just 1.29kWh/day.
These figures indicate that Levallois-Perret's solar potential is heavily skewed towards the warmer months. The long summer days and higher sun angles contribute to peak production from late spring through early autumn. This period is ideal for maximizing solar energy generation and could potentially offset higher electricity demands for cooling during heatwaves.
Optimal Panel Installation
To maximize year-round solar production, fixed 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 paths.
Environmental and Weather Factors
While Levallois-Perret's climate is generally favorable for solar production, there are some factors that could impact efficiency:
- Cloud cover: The region experiences frequent cloudy days, especially in winter, which can reduce solar output.
- Urban pollution: Being close to Paris, air pollution might slightly decrease panel efficiency.
To mitigate these issues, regular panel cleaning is recommended to remove any accumulated dirt or pollutants. Additionally, using high-efficiency panels and micro-inverters can help maximize production even during periods of lower sunlight.
In conclusion, while Levallois-Perret isn't ideal for year-round solar production due to significant seasonal variations, it still offers considerable potential, especially during the warmer months. With proper installation and maintenance, solar PV can be a valuable contributor to the area's energy mix.
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 Levallois-Perret
Seasonal solar PV output for Latitude: 48.8948, Longitude: 2.2874 (Levallois-Perret, 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 Levallois-Perret, France
To maximize your solar PV system's energy output in Levallois-Perret, France (Lat/Long 48.8948, 2.2874) 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 Levallois-Perret, 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 Levallois-Perret, 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 Levallois-Perret, 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 Levallois-Perret, 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 Levallois-Perret, France
Levallois-Perret, located in the northwestern suburbs of Paris, France, sits on relatively flat terrain along the right bank of the River Seine. The area surrounding this commune is characterized by a dense urban landscape typical of the Paris metropolitan region. The topography is predominantly level, with only slight variations in elevation across the area. The Seine River forms a natural boundary to the southwest of Levallois-Perret, while the rest of the surrounding area is a continuous urban expanse. The terrain is mostly artificial, shaped by centuries of human habitation and development. Buildings, roads, and other urban infrastructure dominate the landscape, leaving little room for natural topographic features.
Potential for Large-Scale Solar PV
Given the dense urban nature of Levallois-Perret and its surrounding areas, finding suitable locations for large-scale solar PV installations within the immediate vicinity would be challenging. The limited open space and the prevalence of buildings and infrastructure make it difficult to accommodate expansive solar farms. However, there are potential alternatives that could be explored in the broader region: Rooftop installations on large commercial or industrial buildings in the outskirts of Paris could provide significant surface area for solar panels. While not traditional large-scale ground-mounted installations, these rooftop systems could collectively generate substantial amounts of solar energy. Former industrial sites or brownfields in the greater Paris region, if available, could be repurposed for solar energy production. These areas would need to be carefully assessed for environmental concerns and remediation requirements. Agricultural areas further from the city center, particularly to the north and east of Paris, might offer more suitable locations for large-scale solar PV installations. However, this would require balancing energy production needs with preserving valuable agricultural land. It's important to note that any large-scale solar PV project in this region would need to carefully consider local regulations, land use policies, and the impact on the urban and suburban landscape. Given the constraints of the densely populated area around Levallois-Perret, a distributed approach to solar energy production, utilizing multiple smaller installations across various suitable locations, might be more feasible than a single large-scale project.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. This means that 2.80% of France's total energy as a country comes from solar PV (that's 30th in the world). Each year France is generating 218 Watts from solar PV per capita (France ranks 23rd in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in France?
