Solar PV Analysis of Asnieres-sur-Seine, France
In Asnieres-sur-Seine, France (latitude: 48.9119, longitude: 2.2875), the efficacy of solar photovoltaic (PV) power generation varies with each season due to changes in sunlight intensity and duration. On average, for every kilowatt of installed solar capacity, it can produce up to 5.56 kWh per day during the summer months when daylight hours are at their peak and sunlight is most intense.
As we transition into autumn, the average daily energy yield drops to approximately 2.89 kWh per kW due to shorter daylight hours and less intense sunlight as compared to summer months.
Winter sees a further decline in solar energy production with an average yield of approximately 1.34 kWh per day per kW installed due to even shorter daylight hours and lower sun angles which result in less direct sunlight reaching the panels.
However, as spring approaches, there is a significant increase in solar energy production with an approximate yield of about 4.97 kWh/day/kW owing to longer daylight hours and higher sun angles compared to winter months.
The ideal panel tilt angle for fixed installations at this location is about 42 degrees facing south which optimizes exposure towards incoming sunlight throughout the year while minimizing potential shading from surrounding structures or vegetation.
Solar PV power generation may be affected by local weather conditions such as cloud cover reducing direct sunlight reaching the panels or high winds potentially causing physical damage or misalignment of panels affecting overall system performance. To mitigate these factors during installation, it's recommended that systems are designed with durable materials able to withstand harsh weather conditions and incorporate measures such as windbreaks if necessary while ensuring regular maintenance checks for any potential issues that may reduce system performance over time.
Despite these challenges though Asnières-sur-Seine remains a highly suitable location for generating renewable energy through solar PV systems year-round given its geographical position which allows for considerable sun exposure across all seasons.
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 Asnieres-sur-Seine
Seasonal solar PV output for Latitude: 48.9119, Longitude: 2.2875 (Asnieres-sur-Seine, 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 Asnieres-sur-Seine, France
To maximize your solar PV system's energy output in Asnieres-sur-Seine, France (Lat/Long 48.9119, 2.2875) 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 Asnieres-sur-Seine, 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 Asnieres-sur-Seine, 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 Asnieres-sur-Seine, 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 Asnieres-sur-Seine, 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 Asnieres-sur-Seine, France
The topography around Asnieres-sur-Seine is fairly flat, with some low hills to the east and south. The area is mostly composed of grassy fields and open farmland, making it an ideal location for large-scale solar PV installations. The open space allows for plenty of sunlight exposure throughout the day, while the relatively flat terrain minimizes land preparation costs. Additionally, there are no major bodies of water nearby that could interfere with solar panel installation and operation. Areas near Asnieres-sur-Seine that would be most suited for large-scale solar PV include La Courneuve, Gennevilliers, Clichy Sous Bois, Stains, Drancy, Pantin and Le Blanc Mesnil.
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.
