Grasse, France, situated at latitude 43.6698 and longitude 6.9202, presents a moderately favorable location for solar PV energy generation throughout the year. This picturesque town in the Northern Temperate Zone experiences significant seasonal variations in solar energy production.

Seasonal Solar Performance

Summer stands out as the peak season for solar energy generation in Grasse, with an impressive daily output of 7.31 kWh per kW of installed solar capacity. Spring follows as the second-most productive season, yielding 5.72 kWh per day. Autumn sees a considerable drop in production to 3.48 kWh daily, while winter experiences the lowest output at 2.19 kWh per day.

The substantial difference between summer and winter production highlights the importance of proper system sizing to ensure adequate energy supply during less productive months. However, the relatively high spring and summer outputs make Grasse an attractive location for solar PV installations overall.

Optimal Panel Positioning

For fixed panel installations in Grasse, the ideal tilt angle to maximize year-round solar production is 37 degrees facing south. This angle takes into account the town's latitude and seasonal sun positions, ensuring optimal exposure throughout the year.

Environmental Considerations

While Grasse benefits from its Mediterranean climate, there are a few environmental factors that could potentially impact solar production:

1. Occasional mistral winds, which can carry dust and debris
2. Infrequent hailstorms during transitional seasons

To mitigate these factors, it's advisable to install robust, high-quality solar panels with tempered glass to withstand potential hail damage. Regular cleaning and maintenance can help combat dust accumulation from mistral winds, ensuring consistent performance.

In conclusion, Grasse offers a promising location for solar PV installations, with particularly strong potential during spring and summer months. By addressing the few environmental challenges and optimizing panel positioning, solar energy can be effectively harnessed in this charming French town.

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

Seasonal solar PV output for Latitude: 43.6698, Longitude: 6.9202 (Grasse, 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 37° South in Grasse, France

To maximize your solar PV system's energy output in Grasse, France (Lat/Long 43.6698, 6.9202) throughout the year, you should tilt your panels at an angle of 37° 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 Grasse, 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 Grasse, France. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 37° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
27° South in Summer	48° South in Autumn	58° South in Winter	36° 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 Grasse, 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 Grasse, 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 Grasse, France

The topography around Grasse, France, is characterized by a diverse and picturesque landscape that combines rolling hills, steep slopes, and valleys. Located in the Alpes-Maritimes department of southeastern France, Grasse sits on the southern slopes of the French Prealps, offering stunning views of the surrounding countryside and the Mediterranean Sea to the south. The terrain in and around Grasse is generally hilly and rugged, with elevations ranging from about 300 to 1,000 meters above sea level. The city itself is perched on a hillside, with its historic center situated at an altitude of approximately 350 meters. As you move away from the city center, the landscape becomes increasingly varied, featuring a mix of gentle slopes and more dramatic inclines. To the north and northeast of Grasse, the terrain becomes more mountainous, with the foothills of the Alps rising steadily. This area is characterized by deeper valleys, steeper slopes, and denser forests. The Loup and Siagne rivers have carved scenic gorges through the limestone rock, creating impressive natural features in the region.

Potential Areas for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would have ample sunlight exposure, relatively flat or gently sloping terrain, and minimal environmental or cultural impact. The plains and plateaus to the west and southwest of Grasse offer promising potential for solar PV development. These areas, including parts of the Var department, feature more open landscapes with fewer steep inclines. The terrain here is generally flatter and receives abundant sunshine throughout the year, making it well-suited for solar energy production. Another area with potential for solar PV installations is the coastal region to the south of Grasse. While this area is more densely populated, there may be opportunities to utilize brownfield sites or integrate solar panels into existing infrastructure. The coastal plains near cities like Cannes and Antibes receive high levels of solar radiation and could accommodate large-scale projects if suitable land is available. It's important to note that any large-scale solar PV development in the region would need to carefully consider environmental impacts, local regulations, and the preservation of the area's natural beauty and cultural heritage. The rugged terrain and forested areas immediately surrounding Grasse may be less suitable for such projects due to their steeper slopes and potential ecological sensitivity.
