Clichy, France presents a moderately suitable location for solar PV energy generation, though it faces typical challenges associated with Northern European climates. Located at coordinates 48.9012, 2.3072 in the Northern Temperate Zone, this area experiences significant seasonal variation in solar energy production.

Seasonal Energy Production Patterns

The solar energy output at Clichy varies dramatically throughout the year. Summer provides the highest production at 5.52 kWh per day per kW of installed capacity, making it the optimal season for solar generation. Spring follows as the second-best period with 4.91 kWh per day per kW, offering nearly comparable performance to summer months. Autumn sees a notable decline to 2.81 kWh per day per kW, while winter presents the most challenging conditions with only 1.30 kWh per day per kW. This represents a more than four-fold difference between peak summer and winter production, highlighting the location's seasonal dependency.

Optimal Panel Configuration

For maximum year-round energy production at Clichy, solar panels should be installed at a fixed tilt angle of 42 degrees facing south. This angle has been calculated to optimize total annual output by accounting for the sun's varying position throughout the year and weighting for solar irradiance potential.

Environmental and Weather Challenges

Several local factors can significantly impact solar production efficiency at this Northern French location:

• Frequent cloud cover and overcast conditions, particularly during autumn and winter months
• High humidity levels that can reduce solar irradiance
• Regular precipitation that may leave water spots and debris on panel surfaces
• Urban air pollution from the greater Paris metropolitan area
• Potential for snow accumulation during winter months

Preventative Measures for Enhanced Production

To maximize solar energy generation despite these challenges, several installation strategies should be considered:

• Install panels with anti-reflective coatings and self-cleaning surfaces to minimize the impact of dust and pollution
• Ensure adequate spacing between panel rows to prevent shading and allow for proper cleaning access
• Use micro-inverters or power optimizers to minimize the impact of partial shading from clouds or debris
• Design mounting systems with sufficient tilt to promote natural water runoff and snow shedding
• Implement regular maintenance schedules, particularly before and after winter months
• Consider tracking systems if space and budget allow, as they can significantly improve performance during lower-light conditions

While Clichy's location presents moderate solar potential compared to more southern European locations, proper system design and maintenance can help ensure reasonable energy production throughout most of the year, with peak performance expected from late spring through early autumn.

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

Seasonal solar PV output for Latitude: 48.9012, Longitude: 2.3072 (Clichy, 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 Clichy, France

To maximize your solar PV system's energy output in Clichy, France (Lat/Long 48.9012, 2.3072) 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 Clichy, 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 Clichy, 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 Clichy, 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 Clichy, 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 Clichy, France

Topographical Features Around Clichy

Clichy sits in the heart of the Île-de-France region, positioned on relatively flat terrain within the Seine River valley. The area forms part of the broader Paris Basin, characterized by gentle rolling plains with minimal elevation changes. The Seine River flows approximately two kilometers south of Clichy, creating a shallow valley that has shaped the local landscape over millennia. The immediate surroundings consist of urbanized flatlands with elevations ranging between 30 and 50 meters above sea level. Small undulations in the terrain create subtle variations, but these changes are hardly noticeable to the casual observer. The landscape slopes very gently toward the Seine, with drainage patterns following this natural gradient. To the north and west of Clichy, the terrain gradually rises toward the low hills that characterize the outer suburbs of Paris. These areas feature slightly more pronounced topographical variation, though still remaining within the category of gentle rolling countryside. The highest points in the region reach approximately 100 to 130 meters above sea level, creating modest ridgelines that run roughly east-west.

Geological Foundation and Land Use

The underlying geology consists primarily of sedimentary rocks from the Tertiary period, including limestone, sandstone, and clay deposits. This geological foundation has created relatively stable ground conditions throughout the region. The soil composition varies between clay-rich areas near the river and sandier soils on slightly elevated ground. Agricultural land historically dominated the region before urban development transformed much of the landscape. Remnants of this agricultural heritage can still be found in the outer suburbs, where open fields and farming operations continue on flatter ground. These areas represent some of the most suitable terrain for large-scale development projects.

Optimal Areas for Large-Scale Solar Development

The most promising locations for extensive solar photovoltaic installations lie in the agricultural zones northwest and northeast of Clichy. These areas combine several advantageous characteristics: relatively flat terrain that minimizes grading requirements, lower population density that reduces land acquisition complexity, and existing agricultural use that presents fewer obstacles to rezoning. The plateau areas extending toward Argenteuil and Sannois offer particularly suitable conditions. The gentle slopes in these locations provide natural drainage while maintaining the flat orientation essential for optimal panel positioning. The terrain requires minimal preparation work, making construction more economical and environmentally sustainable. Southeast toward Créteil and beyond, additional suitable areas exist on the flat plains that extend toward the Marne River valley. These locations benefit from the same geological stability and gentle topography that characterizes the broader region. The agricultural nature of much of this land makes it potentially available for solar development while maintaining compatibility with certain farming practices. Areas closer to the Seine River, while topographically suitable, present challenges related to flood risk management and existing infrastructure density. The river valley floor offers excellent flat terrain, but regulatory considerations and existing development patterns make these locations less practical for large-scale installations. The rolling hills to the north, while offering some elevation advantages, present increased complexity for installation and maintenance. The steeper slopes in these areas require more sophisticated mounting systems and can create shading issues between panel rows, reducing overall efficiency and increasing development costs.
