Solar PV Analysis of Talence, France
The location at Talence, France is fairly good for generating energy through solar panels all year round. However, the efficiency and productivity of these panels will vary significantly with each season.
In simple terms, a solar panel's job is to convert sunlight into electricity. The more sunlight it gets, the more electricity it can generate. So in summer when days are long and sunny, you can expect your solar panels to produce about 6.22 kilowatt-hours (kWh) of electricity per day for every kilowatt (kW) of solar power installed. That's quite productive!
As we move into autumn though, days get shorter and there's less sunlight available so your daily output drops down to about 3.27 kWh/day per kW installed.
Winter sees the least amount of daylight hours and often has cloudier weather which further reduces the amount of sunlight hitting your panels; hence you'll see an even lower production rate - around 1.80 kWh/day per kW installed.
Spring picks up again with longer days and generally clearer skies resulting in an output around 5.41 kWh/day per kW installed.
To maximize year-round production from your solar panels at this location, they should be tilted at a specific angle -39 degrees facing south- towards the sun as much as possible throughout the day.
As far as environmental or weather factors that could impede solar production at this location goes; cloudy or rainy weather would obviously reduce output because they block direct sunlight from reaching your panels but these are not major concerns if you're looking at annual averages since Talence doesn't have extreme weather conditions that could severely impact performance like heavy snowfall or regular sandstorms might do in other locations.
However local factors such as shading from trees or buildings could also affect how much sun reaches your panel so it’s important to consider where on your property would be best suited for installation – ideally somewhere open without obstructions blocking out light for a significant part of the day.
To ensure better energy production, regular cleaning and maintenance of your panels can also help. Dirt or debris on the panel surface can block sunlight and reduce efficiency so keeping them clean can improve output.
Overall, Talence is a decent location for solar power generation with its highest productivity in summer followed by spring, autumn and lastly winter.
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 Talence
Seasonal solar PV output for Latitude: 44.8027, Longitude: -0.5922 (Talence, 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 39° South in Talence, France
To maximize your solar PV system's energy output in Talence, France (Lat/Long 44.8027, -0.5922) throughout the year, you should tilt your panels at an angle of 39° 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 Talence, 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 Talence, France. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 39° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 29° South in Summer | 49° South in Autumn | 60° South in Winter | 37° 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 Talence, 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 Talence, 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 Talence, France
Talence is located in the Nouvelle-Aquitaine region of southwestern France. The topography around Talence is relatively flat, with a gentle gradient towards the Garonne River to the north. The area is largely urbanized as it's part of Bordeaux metropolitan area, with a mix of residential and commercial buildings.
Given its urban setting, rooftop solar installations would be most suitable in Talence itself. Such installations could be placed on both residential and commercial buildings.
However, for larger scale ground-mounted solar PV systems, more open and less developed areas would be required. To the south and east of Talence are several rural areas which may have potential for such developments. These include vineyards and agricultural lands that receive plenty of sunlight throughout the year.
It should be noted that any large-scale solar project would require careful planning to minimize impact on local ecosystems or farmland productivity. Moreover, feasibility studies including sun path analysis (solar irradiation levels), grid connectivity possibilities and environmental impact assessment should also be performed before deciding on a specific location for large-scale solar PV installation.
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.
