Nanterre, France is a decent location for generating solar energy throughout the year, although it's not perfect. The amount of electricity that can be produced from solar panels installed here varies with each season.
In summer, you can expect an average of 5.56 kilowatt-hours (kWh) per day for every kilowatt (kW) of installed solar power. This makes it the best time to generate solar energy at this location because sunlight hours are longer and more intense during these months.
Spring also provides good conditions with about 4.97 kWh/day per kW of installed capacity due to increasing daylight hours and sun intensity as we move away from winter.
On the other hand, autumn and winter produce less electricity - around 2.89 kWh/day in autumn and as low as 1.34 kWh/day in winter per kW of installed capacity due to shorter days and lower sun intensity.
For fixed panel installations at this location, tilting panels at an angle of 42 degrees towards the south would maximize their exposure to sunlight throughout the year thereby increasing total annual production from your solar system.
However, there may be some local factors that could affect how much energy your panels produce such as weather patterns or environmental conditions unique to Nanterre or its surrounding areas. For instance:
- Cloudy weather: Overcast skies reduce sunlight reaching your panels hence reducing their output.
- Dust or pollution: These could accumulate on your panels blocking sunlight thus lowering efficiency.
- Shading: Nearby buildings or trees might cast shadows over your panels especially if they're not properly oriented or positioned causing reduced output.
To mitigate against these challenges:
- Regular cleaning will help keep dust off your panel surfaces.
- If shading is a problem, consider using advanced technology like microinverters which allow individual panels in a string to perform independently thus minimizing impact on overall system performance when one panel is shaded.
Remember though that while these factors might affect your system's performance, they don't necessarily make solar energy production impossible. With proper planning and maintenance, you can still generate a significant amount of electricity from your solar installation in Nanterre.
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 Nanterre
Seasonal solar PV output for Latitude: 48.8909, Longitude: 2.2093 (Nanterre, 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 Nanterre, France
To maximize your solar PV system's energy output in Nanterre, France (Lat/Long 48.8909, 2.2093) 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 Nanterre, 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 Nanterre, 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 Nanterre, 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 Nanterre, 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 Nanterre, France
Nanterre, France is located in the Île-de-France region, which is characterized by flat plains and very gentle rolling hills. The city itself is quite urbanized with a mix of residential, commercial and industrial areas.
For large-scale solar photovoltaic (PV) installations, open and flat areas are typically most suitable as they allow for easier installation and maintenance, as well as more efficient operation of the panels. However, considering Nanterre's dense urban development, rooftops of large buildings such as warehouses or factories could be potential sites for solar PV systems. This type of installation can take advantage of existing structures while reducing land use conflicts that might arise from ground-mounted systems.
Around Nanterre there are some larger open spaces including agricultural lands towards the west near Plaisir and Thiverval-Grignon which may be suited to largescale solar PV if zoning regulations permit it. Additionally areas around Orly Airport to the south-east have significant rooftop space on airport buildings that could potentially be used.
It should also be noted that in addition to topography other factors like local climate (amount of sunny days), grid connectivity and local regulations need to be taken into account when choosing locations for large scale solar PV projects.
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.
