Solar Energy Potential in Notre-Dame-de-Sanilhac, France
Notre-Dame-de-Sanilhac, a location in the Dordogne department of France, offers varying potential for solar PV energy generation throughout the year. This assessment examines how suitable this specific location is for solar power production based on seasonal electricity output data. The seasonal solar production at this location follows a predictable pattern typical of the Northern Temperate Zone. Summer delivers the highest energy output at 6.05kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season with 5.27kWh/day per kW. Autumn yields a moderate 3.14kWh/day, while winter production drops significantly to just 1.70kWh/day per kW of installed capacity.Optimal Installation Parameters
For fixed solar panel installations in Notre-Dame-de-Sanilhac, the ideal tilt angle is 39 degrees facing South. This specific angle has been calculated to maximize the total year-round energy production from the solar PV system, taking into account the location's latitude and seasonal solar patterns. The best times for solar generation at this location are clearly the summer months, followed by spring. Together, these two seasons account for approximately 70% of the annual production potential. This creates an opportunity to optimize energy usage patterns to align with these more productive periods.Potential Challenges and Mitigation Strategies
Several environmental factors could potentially impact solar production in Notre-Dame-de-Sanilhac. The region experiences rainfall throughout the year, which can temporarily reduce solar output. Installing panels with good drainage and self-cleaning properties can help mitigate this issue. Winter fog and morning mist, common in the Dordogne valley areas, may reduce production during early hours. Positioning panels to maximize exposure during mid-day and afternoon hours can help compensate for this limitation. Tree coverage and potential shading from surrounding buildings should be carefully assessed before installation. A thorough site survey is recommended to identify optimal positioning that avoids shadows during peak production hours. Snow is relatively rare but not unknown in this region. When it does occur, it could temporarily cover panels. Installing panels at the recommended 39-degree tilt helps snow slide off more easily than a flatter installation would allow. With proper installation planning that accounts for these factors, Notre-Dame-de-Sanilhac represents a moderately good location for solar PV energy generation, with particularly strong potential during the spring and summer months.Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Notre-Dame-de-Sanilhac
Seasonal solar PV output for Latitude: 45.115, Longitude: 0.7086 (Notre-Dame-de-Sanilhac, 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 Notre-Dame-de-Sanilhac, France
To maximize your solar PV system's energy output in Notre-Dame-de-Sanilhac, France (Lat/Long 45.115, 0.7086) 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 Notre-Dame-de-Sanilhac, 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 Notre-Dame-de-Sanilhac, 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 | 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.

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 Notre-Dame-de-Sanilhac, France
Topography of Notre-Dame-de-Sanilhac
Notre-Dame-de-Sanilhac is situated in the Dordogne department of southwestern France, characterized by a gently undulating landscape typical of the Périgord region. The topography around this commune features rolling hills, small valleys, and plateaus that create a varied terrain with elevations generally ranging between 150 and 230 meters above sea level. The area lies within the broader Aquitaine Basin, with limestone bedrock underlying much of the terrain. This geological foundation has contributed to the formation of the distinctive landscape, with some moderate slopes and plateaus interrupted by shallow valleys carved by small streams and tributaries of the Isle River, which flows several kilometers north of the commune. The terrain around Notre-Dame-de-Sanilhac presents a mosaic of agricultural fields, wooded areas, and scattered settlements. The landscape has been shaped by centuries of human activity, particularly farming, which has created open spaces on the gentler slopes and plateaus, while steeper areas often remain forested.Solar PV Potential in the Region
For large-scale solar photovoltaic installations, the most suitable areas near Notre-Dame-de-Sanilhac would be the elevated plateaus and south-facing gentle slopes. These locations offer several advantages for solar energy development: The higher plateaus to the south and southeast of Notre-Dame-de-Sanilhac provide relatively flat terrain that would minimize the need for extensive grading during solar farm construction. These areas typically experience less shadowing from surrounding landscape features, maximizing exposure to sunlight throughout the day. South-facing slopes in the region, particularly those with inclinations between 5-15 degrees, present natural advantages for solar panel placement. These moderate slopes receive more direct solar radiation than flat surfaces in this latitude, potentially increasing energy generation efficiency. Several areas of previously disturbed land, including former agricultural fields on the plateaus surrounding the commune, could be particularly suitable for solar development. These locations often have reduced ecological sensitivity compared to forested areas and may already have some access infrastructure in place. The relatively open landscape in portions of the commune, especially in the agricultural zones extending toward neighboring Marsaneix to the southwest and Coulounieix-Chamiers to the north, offers minimal obstruction from tall vegetation or geographical features that could cast shadows on solar arrays. Areas near existing electrical infrastructure, particularly along the routes connecting to the larger urban center of Périgueux (located about 8 kilometers north), might offer advantages for grid connection, potentially reducing the costs associated with transmitting the generated electricity to the distribution network. When considering potential solar development sites, it's important to note that some portions of the surrounding landscape may have environmental or cultural significance. The wooded valleys and certain historical areas would likely be less suitable for large-scale solar installations due to ecological considerations and heritage preservation priorities.France solar PV Stats as a country
