Solar PV Analysis of Vitrolles, France
Vitrolles, France is in the Northern Temperate Zone and it's a decent place for solar power generation throughout the year. The amount of electricity you can get from each kilowatt of installed solar panels varies with the seasons: you'll get about 7.52 kilowatt-hours per day in summer, 5.93 kWh/day in spring, 3.60 kWh/day in autumn, and only 2.23 kWh/day during winter.
This means that summer and spring are the best times for generating solar energy at this location because longer daylight hours allow more sunlight to reach your panels. Winter will provide less power due to shorter days and lower sun position.
If you're installing fixed panel installations here, aim to tilt them at an angle of approximately 37 degrees facing southward; this helps maximize total annual production from your solar photovoltaic (PV) system.
As for local factors that could potentially impede solar production - Vitrolles does experience some weather variations like cloudy or rainy days which can reduce sunlight exposure on your panels but not significantly enough to negate its viability as a good location for PV systems installation.
To mitigate these effects when installing solar PV systems, consider integrating energy storage solutions like batteries into your setup so any excess power generated during sunny periods can be stored for use during less sunny or night-time periods. Regular cleaning and maintenance of your panels will also ensure they function optimally by removing dirt or debris which might block sunlight.
Additionally, while not strictly environmental factors but still relevant locally - potential shading issues such as nearby buildings or trees could affect panel efficiency so it’s important when planning installation to choose locations with clear sky visibility where possible.
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 Vitrolles
Seasonal solar PV output for Latitude: 43.4579, Longitude: 5.244 (Vitrolles, 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 37° South in Vitrolles, France
To maximize your solar PV system's energy output in Vitrolles, France (Lat/Long 43.4579, 5.244) throughout the year, you should tilt your panels at an angle of 37° 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 Vitrolles, 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 Vitrolles, France. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 37° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 27° South in Summer | 47° South in Autumn | 58° South in Winter | 36° 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 Vitrolles, 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 Vitrolles, 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 Vitrolles, France
Vitrolles, France is located in the Provence-Alpes-Côte d'Azur region of southeastern France. The topography of this area is characterized by a mix of flat plains, rolling hills, and rugged mountainous areas. There are also several bodies of water nearby including ponds and the Mediterranean Sea to the south.
The terrain around Vitrolles could potentially be suitable for large-scale solar PV installations in certain locations. The flat plains and rolling hills would likely be the most suitable due to their ease of access and installation compared to more rugged or steep terrains. However, it's important to consider that these areas may also be used for agriculture or residential purposes.
Areas near bodies of water might also be considered due to potential cooling benefits but would need careful assessment regarding environmental impact.
The region receives plenty of sunlight throughout the year which makes it a good candidate for solar power generation. Additionally, southern-facing slopes on hilly terrains could provide optimal sun exposure for solar panels.
However, any decision about where exactly to place large-scale solar PV installations should take into account not only topographical considerations but also factors like local regulations, proximity to power grids or infrastructure, land use restrictions as well as social acceptance among others.
It’s recommended that a detailed feasibility study considering all these aspects should be conducted before deciding on specific sites for large scale solar PV development in this area.
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.
