Juvisy-sur-Orge, France, located in the Northern Temperate Zone, presents a mixed picture for solar PV energy generation throughout the year. This location experiences significant seasonal variations in solar energy production, which is typical for its latitude.

Seasonal Solar Performance

Summer stands out as the most productive season, with an impressive 5.56 kWh per day for each kW of installed solar capacity. Spring follows closely behind, generating 4.97 kWh/day. These seasons offer ideal conditions for solar energy production, with longer days and higher sun angles.

Autumn sees a noticeable decrease in output, producing 2.89 kWh/day. Winter, as expected, is the least productive season, with only 1.34 kWh/day. This significant drop is due to shorter days, lower sun angles, and typically more overcast conditions.

Optimal Panel Installation

To maximize year-round solar energy production at this location, fixed solar panels should be tilted at a 42-degree angle facing south. This angle is calculated to capture the most sunlight across all seasons, balancing the high summer sun with the lower winter sun position.

Environmental and Weather Considerations

While Juvisy-sur-Orge doesn't face extreme environmental challenges for solar production, there are some factors to consider:

• Cloud cover: The region can experience overcast conditions, particularly in autumn and winter, which may reduce solar output.
• Snow: Although not frequent, occasional winter snowfall could temporarily reduce panel efficiency if not promptly removed.

To mitigate these factors, consider installing panels with anti-soiling coatings to reduce snow adherence and ensure easy cleaning. Additionally, a slightly steeper tilt angle than the optimal 42 degrees might be considered to promote self-cleaning and snow shedding, although this would slightly reduce overall annual production.

In conclusion, while Juvisy-sur-Orge isn't ideal for year-round solar production due to its significant seasonal variations, it still offers good potential, especially from spring through autumn. With proper installation and maintenance, solar PV can be a viable renewable energy option for this location.

Solar output per kW of installed solar PV by season in Juvisy-sur-Orge

Seasonal solar PV output for Latitude: 48.6831, Longitude: 2.3859 (Juvisy-sur-Orge, 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 42° South in Juvisy-sur-Orge, France

To maximize your solar PV system's energy output in Juvisy-sur-Orge, France (Lat/Long 48.6831, 2.3859) throughout the year, you should tilt your panels at an angle of 42° 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 Juvisy-sur-Orge, 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 Juvisy-sur-Orge, France. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 42° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
32° South in Summer	52° South in Autumn	62° South in Winter	41° 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 Juvisy-sur-Orge, 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 Juvisy-sur-Orge, 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 Juvisy-sur-Orge, France

The topography around Juvisy-sur-Orge, France, is characterized by a gently rolling landscape typical of the Île-de-France region. Located in the southern suburbs of Paris, this area sits within the Seine valley, with the river Seine flowing nearby to the north. The terrain is generally low-lying, with subtle variations in elevation throughout the surrounding area. To the west and southwest of Juvisy-sur-Orge, the land gradually rises towards the Hurepoix plateau, a slightly elevated region that forms part of the Paris Basin. This area features a mix of small hills and shallow valleys, creating a mildly undulating landscape. The eastern side of Juvisy-sur-Orge is relatively flat, as it extends towards the Orge River valley. The immediate vicinity of Juvisy-sur-Orge is largely urbanized, with a mix of residential areas, commercial zones, and transportation infrastructure. However, as you move further from the town center, especially to the south and southeast, the landscape becomes more rural, with open fields and scattered woodlands.

Potential Areas for Large-scale Solar PV

When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The ideal locations would be relatively flat, open areas with good sun exposure and minimal shading from trees or buildings. Based on these criteria, the following areas near Juvisy-sur-Orge show potential: The agricultural lands to the south and southeast of Juvisy-sur-Orge offer promising locations for solar PV development. These areas are generally flatter and more open, with fewer obstructions to sunlight. The fields between Juvisy-sur-Orge and neighboring towns like Savigny-sur-Orge or Viry-Châtillon could be suitable candidates. Some of the less densely populated areas on the outskirts of nearby towns might also be considered. These could include unused or underutilized industrial zones or brownfield sites that offer large, open spaces without conflicting with residential or prime agricultural land use. It's important to note that while these areas may be topographically suitable, any large-scale solar PV project would need to consider additional factors such as local zoning regulations, environmental impact assessments, and grid connection possibilities. The proximity to Paris and the densely populated nature of the region may present challenges in finding extensive areas for solar farms, so smaller-scale or distributed solar projects might be more feasible in this particular location.
