Solar PV Analysis of Poitiers, France
Poitiers, France is a fairly good location for producing energy through solar photovoltaic (PV) panels all year round. The amount of electricity produced by each kilowatt of installed solar PV varies with the seasons. During summer and spring, the output is higher with 5.86 and 5.29 kilowatt-hours per day respectively. This means that these are the best times of year to generate solar power at this location.
However, during autumn and winter, the output drops to 3.11 and 1.54 kilowatt-hours per day respectively due to fewer hours of sunlight and lower sun angles resulting in less energy being produced.
For a fixed panel installation at this location, it's recommended that panels are tilted at an angle of 40 degrees towards the South for maximum overall yearly production from solar PV.
There could be several factors that might impede solar production in Poitiers including weather conditions like cloudy or rainy days which reduce sunlight exposure on panels; environmental factors like dust or bird droppings which can cover panels reducing their efficiency; topography such as mountains or tall buildings blocking sunlight; local laws restricting installation or use of solar panels etc.
Preventative measures include regular cleaning of panels to remove dust or other obstructions; installing tracking systems so that panels can follow sun's path across sky for maximum exposure; using microinverters which convert direct current (DC) produced by each individual panel into alternating current (AC), allowing them to work independently from each other so if one panel is shaded it doesn't affect others' performance etc.
In conclusion, while there may be some challenges associated with using solar PV in Poitiers due to its specific climate and environment, they can be managed effectively with proper planning and maintenance ensuring good level of energy production throughout most parts of year.
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 Poitiers
Seasonal solar PV output for Latitude: 46.5874, Longitude: 0.3332 (Poitiers, 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 40° South in Poitiers, France
To maximize your solar PV system's energy output in Poitiers, France (Lat/Long 46.5874, 0.3332) throughout the year, you should tilt your panels at an angle of 40° 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 Poitiers, 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 Poitiers, France. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 40° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 30° South in Summer | 50° South in Autumn | 61° South in Winter | 39° 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 Poitiers, 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 Poitiers, 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 Poitiers, France
Poitiers is located in the region of Nouvelle-Aquitaine in western France. The topography of the area is characterized by rolling hills and plains, with a few small rivers running through. The land around Poitiers is primarily used for agriculture, including vineyards and wheat fields.
The climate in Poitiers is temperate, with relatively mild winters and warm summers. It receives a moderate amount of sunlight annually, making it suitable for solar PV installations.
For large-scale solar PV installations, flat or gently sloping areas are generally preferred to maximize exposure to sunlight and minimize installation costs. Therefore, the plains surrounding Poitiers could be suitable for this purpose.
However, specific suitability would also depend on other factors such as local regulations on land use and environmental impact assessments. For instance, while agricultural lands might be physically suitable for installing solar panels due to their flatness and exposure to sun, they may not be legally or ethically appropriate if it means taking away productive farmland or disrupting local ecosystems.
In addition to physical topography and land use considerations, proximity to existing power infrastructure (for easy connection to the grid) would also be an important factor when considering locations for large-scale solar PV installations.
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.
