Les Paris, France, located at 45.6375, 5.7326 in the Northern Temperate Zone, offers a moderately favorable location for solar PV energy generation, though with significant seasonal variations.

Seasonal Solar Production

Solar energy production at Les Paris follows a predictable seasonal pattern. Summer months yield the highest energy output at 6.20kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season with 5.31kWh/day, while autumn drops to 3.11kWh/day. Winter shows the lowest production at just 1.62kWh/day per kW installed.

This pattern creates more than a 3.8-fold difference between the best and worst seasons, which is typical for locations in the mid-latitudes of the Northern Hemisphere. The substantial drop in winter production means that supplementary power sources would be necessary for year-round energy independence.

Optimal Panel Installation

For fixed solar panel installations in Les Paris, the ideal tilt angle to maximize year-round energy production is 39 degrees facing South. This angle has been calculated to optimize annual solar harvest by accounting for the sun's changing position throughout the year and weighting the calculation toward periods of higher potential solar irradiance.

Environmental and Weather Considerations

Several factors could potentially impact solar production at this location:

• Snow accumulation during winter months can significantly reduce output by covering panels, requiring either manual clearing or steep installation angles to promote natural snow shedding
• Morning fog, common in this region of France, may delay full production until later in the day, particularly during autumn and winter
• Dust and pollen accumulation, especially in spring and summer, can gradually reduce panel efficiency if not regularly cleaned
• Potential shading from surrounding Alpine foothills or vegetation should be carefully assessed before installation

To mitigate these challenges, installation should include regular maintenance schedules for cleaning, snow-shedding panel mounts where appropriate, and careful site selection to minimize shading issues. Microinverters or power optimizers can also help minimize production losses when partial shading is unavoidable.

Overall, Les Paris represents a moderate location for solar energy production, with excellent potential during spring and summer months but requiring supplementary energy sources during the lower-production winter period.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Ideally tilt fixed solar panels 39° South in Les Paris, France

To maximize your solar PV system's energy output in Les Paris, France (Lat/Long 45.6375, 5.7326) 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 Les Paris, 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 Les Paris, 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	59° 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.

Calculate solar panel row spacing in Les Paris, 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 Les Paris, 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 Les Paris, France

The topography around Les Paris, France, located at coordinates 45.6375° N, 5.7326° E, is characterized by diverse terrain features typical of the eastern French pre-Alpine region. This area sits within the Savoie department, nestled between the western edge of the Alps and the Rhône Valley.

Regional Terrain

Les Paris is situated in a transitional landscape where the flat plains of the Rhône Valley begin to give way to the foothills of the Alps. The immediate vicinity features gently rolling hills interspersed with small plateaus and valleys. Elevation in this area typically ranges from approximately 250 to 500 meters above sea level, creating a moderately varied topography. To the east, the terrain becomes progressively more mountainous as it approaches the Massif des Bauges and the Chaîne de l'Épine, where elevations increase significantly. These mountain ranges form natural barriers and create distinctive microclimates throughout the region. To the west, the landscape gradually flattens toward the Rhône River valley, offering more expansive, open areas.

Local Features

The immediate area around Les Paris includes several small valleys formed by local waterways that eventually feed into the larger river systems of the region. These valleys often have south-facing slopes that receive substantial solar exposure throughout the day. The terrain is frequently punctuated by small woodlands and agricultural fields, creating a mosaic pattern across the landscape. The soil composition varies from areas of limestone to more fertile alluvial deposits in the valley floors. This geological diversity has influenced both the natural vegetation and human land use patterns throughout the region's history.

Suitable Areas for Solar PV Development

For large-scale solar photovoltaic installations, several nearby areas present favorable conditions: The gently sloping south-facing hillsides to the northwest of Les Paris offer excellent potential for solar energy capture. These areas benefit from minimal shadowing effects and optimal orientation toward the sun's path. The moderate incline of these slopes also provides natural drainage while maintaining good solar exposure throughout the year. The plateau regions to the southwest, extending toward the Rhône Valley, present another promising option for solar development. These relatively flat expanses provide ample space for large installations while still maintaining good solar exposure. The reduced elevation of these areas also typically means less cloud cover compared to the higher mountain regions to the east. Former agricultural lands that are less productive or have been set aside could be repurposed for solar installations. Several such areas exist within a 10-kilometer radius of Les Paris, particularly in the more level terrain to the west and southwest. Areas to avoid would include the steeper eastern slopes that face the Alps, as these receive more variable sunlight due to shadowing from the mountains and experience more frequent cloud formation. Similarly, the narrow valley bottoms, while flat, often experience morning fog and shadowing from surrounding hills, making them less ideal for solar energy production. The most promising solar development zones would be those that combine favorable topography with proximity to existing electrical infrastructure and access roads, minimizing the need for extensive new construction while maximizing energy production potential.
