Solar PV Analysis of Fontenay-sous-Bois, France
In Fontenay-sous-Bois, France (latitude: 48.855, longitude: 2.4836), solar power generation is a viable option due to its relatively favorable climate throughout the year. The average daily energy production per kW of installed solar capacity varies by season, with summer yielding 5.56 kWh per kW, autumn producing 2.89 kWh per kW, winter generating a lower output of 1.34 kWh per kW, and spring offering an impressive 4.97 kWh per kW.
Located in the Northern Temperate Zone, Fontenay-sous-Bois experiences moderate weather conditions that are generally conducive to solar power generation; extreme events such as snowstorms or hurricanes are rare occurrences in this region. However, cloud cover can impact the efficiency of solar panels during any season by limiting the amount of sunlight available for conversion into electricity through photovoltaic cells.
To optimize energy production at this location, it is recommended that fixed-panel installations be tilted at an angle of 42 degrees facing southward to maximize exposure to sunlight throughout the year. While there may be some local factors that could potentially impede solar production—such as shading from nearby buildings or trees—these obstacles can often be mitigated through careful site selection and strategic panel placement during installation.
Overall, Fontenay-sous-Bois presents a suitable environment for harnessing solar power on a year-round basis with proper planning and consideration given to seasonal variations in energy production and potential local impediments to sunlight access.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 627 locations across France. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Fontenay-sous-Bois
Seasonal solar PV output for Latitude: 48.855, Longitude: 2.4836 (Fontenay-sous-Bois, 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 Fontenay-sous-Bois, France
To maximize your solar PV system's energy output in Fontenay-sous-Bois, France (Lat/Long 48.855, 2.4836) 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 Fontenay-sous-Bois, 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 Fontenay-sous-Bois, 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 Fontenay-sous-Bois, 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 Fontenay-sous-Bois, 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 Fontenay-sous-Bois, France
The topography around Fontenay-sous-Bois is generally flat with some gentle rolling hills. The nearby areas that would be most suited to large scale solar PV are the flat plains and open fields, as these provide plenty of space for large arrays of photovoltaic panels. Additionally, any areas with high levels of insolation (sunlight) would also be ideal for maximizing energy production from the solar panels.
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?
Yes, there are several incentives for businesses wanting to install solar energy in France. The French government offers a range of financial incentives and tax credits to encourage businesses to invest in renewable energy sources such as solar power. These include the Feed-in Tariff (FiT), which pays businesses for the electricity they generate from their solar panels, and the Investment Tax Credit (ITC), which provides a 30% tax credit on investments made in renewable energy systems. Additionally, businesses may be eligible for grants or loans from local authorities or regional development agencies.
