Oltingue, Grand Est, France, situated at latitude 47.4928 and longitude 7.3891, presents a varied landscape for solar energy production throughout the year. This location in the Northern Temperate Zone experiences significant seasonal fluctuations in solar potential, which directly impacts the efficiency of photovoltaic (PV) systems.

Seasonal Solar Performance

The solar energy output at Oltingue varies dramatically across the seasons. Summer stands out as the most productive period, with an impressive 5.69 kWh per day for each kilowatt of installed solar capacity. Spring follows closely, generating 4.83 kWh/day. Autumn sees a notable decrease to 2.95 kWh/day, while winter experiences the lowest output at just 1.39 kWh/day.

These figures highlight the stark contrast between the warm and cold seasons, with summer producing more than four times the energy of winter. This pattern suggests that solar energy systems in Oltingue will be most effective from late spring through early autumn, with peak performance in the summer months.

Optimal Panel Installation

To maximize year-round solar energy production in Oltingue, Grand Est, fixed solar panels should be installed at a tilt angle of 40 degrees facing south. This angle has been calculated to optimize the panels' exposure to sunlight throughout the year, taking into account the location's latitude and the Earth's orbit.

Environmental Considerations

While Oltingue's location is generally favorable for solar energy production, there are some environmental factors to consider. The region experiences a continental climate with cold winters, which can lead to snow accumulation on solar panels. This can temporarily reduce energy output during winter months.

To mitigate this issue, installers should consider using panels with a steeper tilt angle or implementing automated cleaning systems. Additionally, ensuring panels are easily accessible for manual snow removal can help maintain efficiency during snowy periods.

Another factor to consider is the potential for cloudy days, particularly in autumn and winter. While this is a common challenge in many European locations, it underscores the importance of using high-efficiency panels and potentially incorporating energy storage solutions to balance out the seasonal variations in solar output.

In conclusion, while Oltingue's solar potential varies significantly throughout the year, proper installation techniques and consideration of local environmental factors can help maximize the effectiveness of solar PV systems in this location.

Solar output per kW of installed solar PV by season in Oltingue

Seasonal solar PV output for Latitude: 47.4928, Longitude: 7.3891 (Oltingue, 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 Oltingue, France

To maximize your solar PV system's energy output in Oltingue, France (Lat/Long 47.4928, 7.3891) 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 Oltingue, 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 Oltingue, 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	61° South in Winter	40° 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 Oltingue, 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 Oltingue, 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 Oltingue, France

The topography around Oltingue, France, located at coordinates 47.4928 latitude and 7.3891 longitude, is characterized by a diverse landscape typical of the Alsace region. This area is situated in the foothills of the Jura Mountains, presenting a mix of gently rolling hills, small valleys, and expansive plateaus. The terrain gradually rises from the Rhine Valley in the east towards the more elevated regions in the west. Oltingue itself is nestled in a small valley, surrounded by low-lying hills covered with a patchwork of forests, agricultural fields, and meadows. The elevation in this area ranges from approximately 350 to 500 meters above sea level, creating a picturesque rural setting. Small streams and tributaries of the Rhine River meander through the landscape, contributing to the region's fertility and natural beauty.

Potential Areas for Large-Scale Solar PV

When considering locations for large-scale solar photovoltaic (PV) installations near Oltingue, several factors come into play. The most suitable areas would be those with ample sunlight exposure, relatively flat terrain, and minimal environmental impact. The open agricultural lands to the east and southeast of Oltingue present promising opportunities for solar PV development. These areas benefit from gentler slopes and fewer obstructions, allowing for optimal solar panel placement. The expansive fields in this direction provide sufficient space for large-scale installations without significant topographical challenges. Another potential location lies to the north of Oltingue, where the landscape opens up into wider plateaus. These elevated areas receive good sun exposure throughout the day and offer larger continuous spaces for solar farm development. The slightly higher altitude of these plateaus may also contribute to clearer skies and potentially increased solar radiation. It's important to note that while these areas show promise for solar PV installations, any large-scale development would require careful environmental assessment and consideration of local land use regulations. The region's agricultural heritage and natural beauty are significant factors that would need to be balanced with renewable energy goals. In conclusion, the varied topography around Oltingue provides both challenges and opportunities for solar PV development. The most suitable areas are likely to be found in the flatter, open spaces to the east, southeast, and north of the town, where the landscape offers a combination of favorable terrain and good solar exposure.
