Solar PV Analysis of Landivisiau, France
Based on the given information, Landivisiau, Brittany, France can be considered a decent location for generating solar energy year-round, though not necessarily ideal. The amount of electricity produced by solar panels depends on the amount of sunlight they receive. In Landivisiau, Brittany, this varies significantly with the seasons.
In Summer and Spring, you could expect quite good output from your solar panels. With 5.96kWh/day in Summer and 5.21kWh/day in Spring per kW of installed solar panels, these are the best times to generate solar power at this location.
On the other hand, Autumn and Winter see a considerable drop in production due to shorter daylight hours and less intense sun rays - producing only 2.86kWh/day in Autumn and a mere 1.33kWh/day in Winter per kW installed.
To maximize total year-round production from your solar PV system at this location, it's recommended that you tilt your fixed panel installation towards an angle of 41 degrees South - this will ensure that it captures as much sunlight as possible throughout different times of the day and different seasons.
As for local factors that could impede solar production at this location: Since Landivisiau is located in Northern France where cloud cover can be frequent especially during autumn/winter months which may reduce sunlight exposure; also potential shading from nearby buildings or trees should be considered when choosing where to install your panels.
To mitigate these issues:
1) Selecting a site with minimal obstructions (e.g., tall buildings or trees) would help maximize sun exposure.
2) Regular maintenance – including cleaning off any dust or debris on your panels – can help ensure they're working efficiently.
3) You might consider installing more advanced systems with tracking capabilities so they can follow the sun's path across the sky for maximum energy generation.
4) Using high-efficiency modules would also help to capture more light even in low-light conditions.
In conclusion, while Landivisiau is not the most ideal location for solar energy production due to seasonal variations and potential environmental challenges, it's still a viable option with proper installation and maintenance.
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 Landivisiau
Seasonal solar PV output for Latitude: 48.5135, Longitude: -4.07 (Landivisiau, 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 41° South in Landivisiau, France
To maximize your solar PV system's energy output in Landivisiau, France (Lat/Long 48.5135, -4.07) throughout the year, you should tilt your panels at an angle of 41° 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 Landivisiau, 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 Landivisiau, France. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 41° 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 | 40° 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 Landivisiau, 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 Landivisiau, 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 Landivisiau, France
Landivisiau is located in the Brittany region of northwestern France. The topography of this area is characterized by a relatively flat landscape with gentle rolling hills and farmland. It's close to the coast, with a maritime climate that includes moderate temperatures and regular rainfall throughout the year.
When considering large-scale solar photovoltaic (PV) installations, factors such as sunlight exposure, land availability and suitability, proximity to transmission lines, local regulations and environmental considerations must be taken into account.
Given its relatively flat landscape and agricultural nature, there could be potential for ground-mounted solar PV systems in Landivisiau or nearby areas with similar characteristics. However, it should be noted that Brittany does not receive as much sunlight as southern regions of France like Provence-Alpes-Côte d'Azur or Languedoc-Roussillon. Therefore, while it's feasible to install solar PV systems here, their efficiency might not be as high compared to those located in sunnier parts of the country.
Additionally, any proposed system would have to comply with local planning regulations which may limit where installations can occur. For example, they may need to avoid areas of natural beauty or sites of historical significance.
Lastly but importantly too are environmental considerations - ensuring minimal impact on wildlife habitats and maintaining biodiversity should also factor into decisions about where large-scale solar PV installations could be placed.
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.
