Solar Energy Potential in Venesmes, France

Venesmes, France, located at coordinates 46.8426, 2.3142 in the Northern Temperate Zone, offers varying potential for solar PV energy generation throughout the year. This location experiences distinct seasonal patterns in solar electricity production that are worth considering for anyone planning a solar installation in this area. The seasonal electricity output per kilowatt of installed solar capacity shows significant variation. Summer is the most productive season, generating 5.78 kWh per day. Spring follows closely with 5.04 kWh daily production. Autumn sees a moderate decrease to 3.03 kWh per day. Winter presents the greatest challenge with only 1.47 kWh daily generation, less than one-third of the summer output.

Optimal Installation Parameters

For fixed solar panel installations in Venesmes, the ideal tilt angle to maximize year-round energy production is 40 degrees facing South. This specific angle optimizes the capture of solar energy across all seasons, balancing the higher summer sun with the lower winter sun position.

Seasonal Considerations

The substantial difference between summer and winter production indicates that Venesmes experiences the typical seasonal solar patterns of mid-latitude locations in the Northern Hemisphere. The near four-fold difference between summer and winter daily output suggests that supplementary energy sources might be necessary during the winter months if consistent energy supply is required. Spring and summer (March through August) represent the prime solar generation period in Venesmes, accounting for a significantly larger portion of the annual solar energy production. System sizing should take into account this seasonal variability to ensure adequate year-round performance.

Environmental and Weather Factors

The central French location of Venesmes may experience several environmental factors that could impact solar production. Winter months likely bring increased cloud cover, contributing to the lower winter production figures. Occasional snowfall could temporarily reduce output, though this can be mitigated by installing panels at the recommended 40-degree tilt, which helps snow slide off more easily. Dust and pollen accumulation may be relevant factors in this rural area, particularly during spring and summer. Regular cleaning maintenance should be scheduled to prevent gradual efficiency losses. Additionally, the region may experience morning fog in valley areas during autumn and winter months, which could delay peak production until later in the day during these seasons. To maximize production despite these factors, consider installing panels with anti-soiling coatings, implementing automated cleaning systems for larger installations, and ensuring panels are positioned to avoid any potential shading from nearby trees or structures, particularly during lower-sun winter 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 Venesmes

Seasonal solar PV output for Latitude: 46.8426, Longitude: 2.3142 (Venesmes, 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 Venesmes, France

To maximize your solar PV system's energy output in Venesmes, France (Lat/Long 46.8426, 2.3142) 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 Venesmes, 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 Venesmes, 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
31° South in Summer	50° South in Autumn	60° 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 Venesmes, 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 Venesmes, France.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Venesmes, France

The topography surrounding Venesmes, France, situated at 46.8426° N, 2.3142° E, is characterized by gently rolling countryside typical of the Berry region in central France. This area lies within the southern portion of the Paris Basin, featuring modest elevation changes and a predominantly rural landscape. The terrain around Venesmes consists of undulating plains with occasional small hills and shallow valleys, with elevations generally ranging between 150 and 250 meters above sea level. The nearby Cher River valley creates a notable topographical feature, with the river flowing roughly northwest through the region. This waterway has shaped the surrounding landscape over millennia, creating fertile alluvial plains along its course. The valley sides rise gradually from the river, forming gentle slopes rather than steep escarpments.

Local Terrain Features

The immediate vicinity of Venesmes displays a mosaic of agricultural fields, scattered woodlands, and small settlements. The land use is predominantly agricultural, with a mix of crop cultivation and livestock grazing. Small patches of forest dot the landscape, particularly on areas less suitable for farming. The topographical variations, while modest, create a diverse visual landscape with subtle changes in elevation throughout the region. Drainage patterns follow the natural contours of the land, with small streams and tributaries eventually feeding into the Cher River system. These waterways have carved shallow depressions in the landscape, contributing to the gently undulating character of the terrain.

Optimal Areas for Solar PV Development

For large-scale solar photovoltaic installations, several areas near Venesmes present favorable topographical conditions. The most suitable locations would be the gently sloping, south-facing hillsides found throughout the region. These areas offer optimal orientation for solar energy capture while minimizing the engineering challenges associated with very flat or extremely uneven terrain. The agricultural plains to the south and southeast of Venesmes are particularly promising for solar development. These areas combine favorable topography with good solar exposure and typically feature larger parcels of land that could accommodate commercial-scale installations. The slight inclination in these areas also provides natural drainage, reducing potential issues with water accumulation around solar infrastructure. Areas to avoid would include the immediate flood plains of the Cher River and its tributaries, as well as the more densely forested sections where clearing would be environmentally disruptive. Similarly, the steeper hillsides, though limited in this region, would present increased installation costs and potential erosion concerns. The relatively open landscape around Venesmes, with limited natural obstacles like mountains or deep valleys, means that shading issues from topographical features are minimal throughout much of the region. This characteristic is highly favorable for solar energy development, as it allows for efficient panel placement with consistent exposure throughout the day.
