Solar PV Analysis of Poisy, France
The location at Poisy, France, can be considered as a fair place for generating solar energy throughout the year. Solar power output varies greatly with the seasons. During summer and spring, when days are longer and sunnier, you could expect to get more electricity from your solar panels - around 6.36 kilowatt-hours (kWh) per day in Summer and 5.03 kWh/day in Spring for each kilowatt of installed solar panel capacity.
However, during autumn and winter when days are shorter and less sunny, the expected electricity generation drops significantly to about 3.24 kWh/day in Autumn and even lower to 1.93 kWh/day in Winter per kilowatt of installed solar.
In terms of ideal times to generate solar energy at this location based on these figures, it would be during the longer daylight hours of spring and especially summer.
To maximize total year-round production from your installed solar panels here at Poisy, they should ideally be tilted towards south at an angle of about 40 degrees.
As far as environmental or weather factors that might impede solar production at this location go; there could potentially be issues with cloud cover or fog given its proximity to mountainous regions which could block sunlight particularly during winter months thereby reducing efficiency of your panels.
As preventative measures against these potential issues; one option may include installing tracking systems on your panels that allow them move so they always face directly towards the sun regardless where it is in sky thus maximizing their exposure to sunlight through out day despite any weather conditions present.
Furthermore using anti-reflective coating on panel surface can help increase amount light absorbed by them hence boosting their productivity even under cloudy conditions.
Lastly regular cleaning maintenance will ensure no dust or debris build-up occurs which could otherwise hinder sunlight penetration onto panel surfaces thereby reducing their effectiveness over time.
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 Poisy
Seasonal solar PV output for Latitude: 45.9253, Longitude: 6.0658 (Poisy, 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 Poisy, France
To maximize your solar PV system's energy output in Poisy, France (Lat/Long 45.9253, 6.0658) 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 Poisy, 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 Poisy, 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 | 60° South in Winter | 38° 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 Poisy, 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 Poisy, 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 Poisy, France
Poisy, France is located in the Auvergne-Rhône-Alpes region of eastern France. The topography of this area is characterized by a mix of flat plains and rolling hills, with the dramatic peaks of the Alps visible to the east. The landscape around Poisy itself is primarily agricultural, with fields and farmland dominating.
Solar PV systems are most effective when they can receive maximum sunlight exposure throughout the day. This means that flat or gently sloping areas facing south would be ideal for large-scale solar PV installations.
Around Poisy, there are several potential areas suited for large-scale solar PV:
1) Agricultural lands: With appropriate agreements from landowners, these open spaces could accommodate ground-mounted solar panels without obstructing farming activities.
2) Industrial zones: There are some industrial zones around Poisy which have large rooftops suitable for installing solar panels without taking up additional land space.
3) Unused lands: Any undeveloped or unused parcels of land could also be considered for solar panel installation.
However, any plans to install a large-scale solar PV system would require careful assessment including environmental impact studies, grid connectivity possibilities and local regulations regarding renewable energy projects.
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.
