Solar PV Analysis of Lieusaint, France
The location at Lieusaint, France is moderately suitable for generating energy via solar photovoltaic (PV) systems throughout the year. The amount of electricity produced by each kilowatt of installed solar varies with the season.
In summer, each kilowatt of installed solar will produce around 5.56 kWh per day, making this the best time of year for solar energy production at this location. Spring is also quite productive with around 4.97 kWh per day generated per kW installed.
However, in autumn and winter, the output drops significantly to 2.89 kWh/day and 1.34 kWh/day respectively due to shorter daylight hours and less intense sunlight during these seasons.
To maximize yearly energy production from a fixed panel installation here, it's ideal to tilt panels at an angle of 42 degrees facing southward towards the sun's path across the sky.
When considering local factors that could affect solar production in Lieusaint, one must consider weather patterns such as cloud cover or fog which can limit sunlight exposure on PV panels; however data on specific weather conditions would be needed to determine their impact on PV performance there.
Topographical features like buildings or trees can also obstruct sunlight if they're located between your PV system and the sun; therefore choosing a site that provides unobstructed access to direct sunlight throughout most of day would be ideal when installing your system.
Lastly, environmental factors like dust or bird droppings can accumulate on panel surfaces and reduce their efficiency over time; hence regular cleaning maintenance should be scheduled for optimum performance year-round.
Overall while not entirely ideal due to lower output in autumn/winter months; with correct installation angle & regular maintenance Lieusaint could still provide satisfactory levels of solar energy generation 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 Lieusaint
Seasonal solar PV output for Latitude: 48.6399, Longitude: 2.5542 (Lieusaint, 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 Lieusaint, France
To maximize your solar PV system's energy output in Lieusaint, France (Lat/Long 48.6399, 2.5542) 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 Lieusaint, 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 Lieusaint, 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 Lieusaint, 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 Lieusaint, 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 Lieusaint, France
Lieusaint is located in the Île-de-France region of north-central France. The topography of this area is characterized by gentle rolling hills and flat plains. It's part of the Paris Basin, which is a geological region known for its sedimentary rocks and relatively flat terrain.
The area around Lieusaint is primarily urbanized with residential areas, commercial zones, and some agricultural land. However, there are also open fields and undeveloped land that could potentially be suitable for large-scale solar PV installations.
Given the relatively flat topography, several areas could be suited for large-scale solar PV installations:
1) Open Fields: There are various open fields around Lieusaint that could be used for solar farms. These areas usually have good sun exposure and minimal shading from trees or buildings.
2) Commercial/Industrial Roofs: Large commercial or industrial buildings often have expansive roof surfaces that can host a significant number of solar panels.
3) Brownfield Sites: These are previously developed sites that are not currently in use. If there are any such sites in or near Lieusaint, they might be suitable locations to install a large number of solar panels without disturbing natural habitats or prime agricultural land.
4) Agricultural Land: Solar panels can also be installed on less fertile agricultural lands without significantly impacting their use for farming activities - this concept is known as agrivoltaics or dual-use farming.
However, any decision on specific locations would need to consider factors like local planning regulations, grid connection points, potential environmental impacts and local community views among others.
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.
