Loos-en-Gohelle, France shows moderate potential for year-round solar energy generation, though with significant seasonal variations typical of its Northern Temperate Zone location.
Seasonal Solar Performance
The solar output data reveals a clear seasonal pattern at this location. Summer provides the strongest performance at 5.34 kWh per day per kW of installed capacity, making it the prime season for solar generation. Spring follows closely behind with 4.90 kWh per day, offering nearly comparable output levels. Autumn sees a notable decline to 2.49 kWh per day, while winter presents the most challenging period with just 1.14 kWh per day. This represents more than a four-fold difference between peak summer and minimum winter production. The ideal times for solar generation at Loos-en-Gohelle are clearly the warmer months from late spring through summer, with May through August likely providing the most consistent and highest energy yields.Optimal Panel Configuration
For fixed panel installations at this location, the ideal tilt angle is 43 degrees facing south to maximize total year-round production. This angle has been calculated by analyzing daily solar elevation angles throughout the year and weighting them according to solar irradiance potential.Local Factors Affecting Solar Production
Several environmental and weather factors in the Loos-en-Gohelle region can significantly impact solar energy production:- Maritime climate influence: The location's proximity to the North Sea brings frequent cloud cover and overcast conditions, particularly during autumn and winter months
- High humidity and fog: Morning fog and persistent moisture can reduce panel efficiency and create shading effects
- Industrial heritage: The area's mining history may contribute to atmospheric particulates that can accumulate on panels
- Prevailing winds: While beneficial for cooling panels, strong winds can carry dust and debris
Preventative Measures for Optimal Performance
Several installation strategies can help maximize energy production despite these challenges:- Regular cleaning schedules: Implement monthly panel cleaning to remove dust, pollen, and industrial residue
- Anti-reflective coatings: Use specialized panel coatings that perform better in low-light and diffused sunlight conditions
- Proper ventilation spacing: Ensure adequate airflow around panels to prevent moisture buildup and improve cooling
- Micro-inverter systems: Install micro-inverters to minimize the impact of partial shading from fog or debris on individual panels
- Monitoring systems: Deploy real-time monitoring to quickly identify and address performance issues
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 Loos-en-Gohelle
Seasonal solar PV output for Latitude: 50.4557, Longitude: 2.7868 (Loos-en-Gohelle, 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 43° South in Loos-en-Gohelle, France
To maximize your solar PV system's energy output in Loos-en-Gohelle, France (Lat/Long 50.4557, 2.7868) throughout the year, you should tilt your panels at an angle of 43° 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 Loos-en-Gohelle, 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 Loos-en-Gohelle, France. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 43° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 34° South in Summer | 53° South in Autumn | 63° South in Winter | 42° 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 Loos-en-Gohelle, 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 Loos-en-Gohelle, France.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Loos-en-Gohelle, France
Topographical Features of Loos-en-Gohelle
The landscape around Loos-en-Gohelle presents a fascinating blend of natural terrain and industrial heritage. This commune in the Pas-de-Calais department sits within the broader Nord-Pas-de-Calais region, characterized by gently rolling plains typical of northern France. The area forms part of the European Plain, where elevations remain relatively modest, creating an undulating countryside that rises and falls in gentle waves across the horizon. The most striking topographical features in this region are the artificial hills known as "terrils" - massive slag heaps created from coal mining operations that dominated the area for over a century. These conical mounds of mining waste now tower above the surrounding landscape, with some reaching heights of over 180 meters above sea level. The twin terrils of Loos-en-Gohelle have become iconic landmarks, visible from considerable distances across the relatively flat surrounding terrain.Natural Terrain and Drainage
The underlying geology consists primarily of sedimentary rocks, with chalk formations common throughout the region. The natural topography slopes gently from southeast to northwest, following the broader drainage patterns that eventually lead toward the English Channel. Small valleys carved by streams and seasonal watercourses create subtle variations in the landscape, though these depressions are generally shallow and do not dramatically alter the overall character of the terrain. Agricultural fields dominate much of the surrounding countryside, with the relatively flat to gently sloping land having been cultivated for centuries. These open spaces are punctuated by small woodlands, hedgerows, and scattered rural settlements. The soil composition varies across the area, with some regions featuring clay-rich earth while others contain more sandy or chalky substrates.Urban Development and Infrastructure
The settlement pattern reflects the region's industrial heritage, with former mining communities creating a network of towns and villages connected by roads and former railway lines. Urban development tends to be concentrated in valley bottoms and on gentler slopes, leaving steeper terrain and the artificial hills largely undeveloped. Transportation infrastructure includes major roads that follow the natural contours of the land, generally running along valley floors or across the broader plateaus. The legacy railway network, much of which was originally built to serve the mining industry, created linear corridors through the landscape that remain important features today.Optimal Areas for Large-Scale Solar Development
The most suitable locations for extensive solar photovoltaic installations would be the broad, gently sloping plateaus that extend across the agricultural areas surrounding Loos-en-Gohelle. These elevated plains offer several advantages, including minimal shading from topographical features and excellent accessibility for construction and maintenance activities. Former industrial sites present particularly attractive opportunities for solar development. Many of these areas have existing electrical infrastructure connections and are already cleared of vegetation, reducing development costs and environmental impacts. The flatter portions of reclaimed mining land could accommodate large arrays without requiring significant site preparation. The southern-facing slopes of the artificial terrils themselves could potentially support solar installations, though the steepness of these slopes would require careful engineering consideration. The surrounding agricultural plateaus, particularly those with gentle southern exposures, represent the most practical locations for utility-scale solar farms. Areas to avoid would include the steeper slopes of natural valleys, locations prone to seasonal flooding near watercourses, and regions where existing woodland or important agricultural land might be impacted. The relatively open nature of much of the surrounding countryside means that large solar installations could be developed with minimal topographical constraints in many locations.France solar PV Stats as a country
France ranks 11th in the world for cumulative solar PV capacity, with 14,718 total MW's of solar PV installed. This means that 2.80% of France's total energy as a country comes from solar PV (that's 30th in the world). Each year France is generating 218 Watts from solar PV per capita (France ranks 23rd in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in France?
Yes, there are several incentives for businesses wanting to install solar energy in France. The French government offers a range of financial incentives and tax credits to encourage businesses to invest in renewable energy sources such as solar power.
