The location at Maisons-Laffitte, France is decent for generating energy via solar panels throughout the year. The amount of electricity that can be produced varies by season. In summer, you can expect to generate about 5.56 kilowatt-hours (kWh) of electricity per day for each kilowatt (kW) of solar panels you have installed - this is the best time of year for solar production here. In autumn, that number drops to about 2.89 kWh/day per kW, and in winter it's even lower at around 1.34 kWh/day per kW which is not ideal but still functional if you have enough panels installed or additional power sources available during these times.
Spring sees a significant increase again with approximately 4.97 kWh/day per kW expected to be generated from your solar panel installation which makes it another good time of the year for producing solar energy.
For a fixed panel installation in this location, tilting your panels at an angle of 42 degrees facing south will help maximize their total energy production all year round.
As far as local factors go that could impact your ability to produce electricity from sunlight here:
1) Weather plays a big role - cloudy days mean less sunlight reaching your panels and thus less electricity being produced.
2) Physical obstructions such as tall trees or buildings casting shadows on your panels can also reduce their output significantly.
3) Dust and debris on the surface of your panels can obstruct sunlight too; regular cleaning helps ensure maximum efficiency.
To prevent some of these issues:
- Choose an installation site with minimal shading.
- Install more than just one row or column of panels so if one area gets shaded others are still exposed.
- Regularly clean off any dust or debris from the surface of your solar PV modules using soft brushes or specialized cleaning equipment designed specifically for use on photovoltaic systems.
Remember though: while taking these measures can help increase your solar energy production, the most significant factor is always going to be the amount of sunlight available in your particular location - and that's something you cannot change.
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 Maisons-Laffitte
Seasonal solar PV output for Latitude: 48.9504, Longitude: 2.1482 (Maisons-Laffitte, 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 Maisons-Laffitte, France
To maximize your solar PV system's energy output in Maisons-Laffitte, France (Lat/Long 48.9504, 2.1482) 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 Maisons-Laffitte, 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 Maisons-Laffitte, 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 |
|---|---|---|---|
| 33° 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 Maisons-Laffitte, 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 Maisons-Laffitte, 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 Maisons-Laffitte, France
Maisons-Laffitte is located in the Île-de-France region of north-central France. The area is generally flat with some small undulations, and it's characterized by urban development with residential areas, parkland, and some forested regions nearby.
The River Seine runs to the south of Maisons-Laffitte which could potentially pose a flooding risk for ground-based solar farms. However, the broad river valley could also provide a good location for floating solar PV installations if local regulations permit.
In terms of land-based installations, large-scale solar PV systems require significant open space that is free from shading. Therefore, less densely populated areas with few tall structures or trees would be best suited. In this case, agricultural lands or cleared areas within nearby forests might be suitable if they are not protected for environmental reasons.
However, given that this region is highly developed and densely populated (it's part of Paris metropolitan area), rooftop solar installations on commercial or industrial buildings may be more feasible than large-scale ground-mounted systems. This would also avoid potential land use conflicts and minimize environmental impact.
One should conduct a detailed site-specific assessment considering factors such as local climate (amount of sunlight), existing infrastructure (grid connectivity), land ownership and zoning laws before deciding on any potential sites for large scale solar PV installation.
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.
