Solar PV Analysis of Goussainville, France
The location in Goussainville, France, is moderately suitable for solar PV energy generation, with significant seasonal variations. Here's a breakdown in simple terms:
1. Summer (June to August): Excellent solar production, with 5.41 kWh per day for each kilowatt of installed solar panels.
2. Spring (March to May): Very good production, close to summer levels, with 5.00 kWh per day.
3. Autumn (September to November): Moderate production, about half of summer levels, with 2.77 kWh per day.
4. Winter (December to February): Poor production, less than a quarter of summer levels, with only 1.26 kWh per day.
The best times for solar energy production at this location are from March to August, covering spring and summer. During these months, the days are longer, and the sun is higher in the sky, resulting in more direct sunlight hitting the panels.
For fixed panel installations, the ideal angle to tilt the panels for maximum year-round production is 42 degrees facing south. This angle helps optimize energy capture throughout the year, considering the changing position of the sun across seasons.
Regarding environmental or weather factors that could impede solar production:
1. Cloud cover: The region experiences significant cloud cover, especially in autumn and winter, which can reduce solar energy production.
2. Rain and humidity: The area has a temperate climate with regular rainfall, which can affect panel efficiency and require more frequent cleaning.
3. Snow: Although not extremely common, occasional snowfall in winter can temporarily cover panels, reducing output.
To address these factors and ensure greater energy production, consider the following preventative measures:
1. Use high-efficiency panels that perform better in low-light conditions.
2. Install a robust mounting system that can withstand strong winds and support occasional snow loads.
3. Implement an automated cleaning system or schedule regular manual cleaning to remove dirt, dust, and potential snow buildup.
4. Consider adding a solar tracking system to maximize energy capture, especially during the productive months.
5. Use micro-inverters or power optimizers to minimize the impact of partial shading on overall system performance.
By implementing these measures, you can help optimize solar energy production at this location despite the seasonal variations and weather-related challenges.
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 Goussainville
Seasonal solar PV output for Latitude: 49.0125, Longitude: 2.4631 (Goussainville, 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 Goussainville, France
To maximize your solar PV system's energy output in Goussainville, France (Lat/Long 49.0125, 2.4631) 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 Goussainville, 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 Goussainville, 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 |
|---|---|---|---|
| 33° 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 Goussainville, 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 Goussainville, 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 Goussainville, France
Goussainville is a commune located in the Val-d'Oise department in the Île-de-France region, north of Paris. To describe the topography and assess areas suitable for large-scale solar PV, I'll provide an overview of the landscape and then discuss potential locations:
Topography:
1. Generally flat terrain: The area around Goussainville is predominantly flat or gently rolling, typical of the Paris Basin region.
2. Low elevation: The elevation is relatively low, ranging from about 50 to 100 meters above sea level.
3. Agricultural land: Much of the surrounding area consists of agricultural fields and open spaces.
4. Urban areas: Goussainville itself and nearby towns introduce some built-up areas into the landscape.
5. River valleys: The Oise River flows to the east of Goussainville, creating some subtle variations in the terrain.
Areas potentially suited for large-scale solar PV:
1. Agricultural lands: The extensive agricultural areas surrounding Goussainville could be suitable for solar farms, especially if they are less productive farmlands.
2. Former industrial sites or brownfields: Any abandoned industrial areas or remediated brownfields in the region could be repurposed for solar installations.
3. Airport vicinity: The nearby Paris-Charles de Gaulle Airport has large open spaces that might be suitable for solar panels, though air traffic considerations would need to be taken into account.
4. Open fields between towns: The spaces between urban areas in the region could potentially accommodate solar installations.
5. Gentle south-facing slopes: Any areas with slight south-facing inclines would be particularly advantageous for maximizing solar exposure.
Factors to consider:
1. Land availability and current use
2. Proximity to electrical infrastructure
3. Local zoning and regulations
4. Environmental impact and biodiversity considerations
5. Visual impact on the landscape
6. Compatibility with nearby airport operations
It's important to note that while the topography is generally favorable for solar PV installations, the Île-de-France region is densely populated and land use is often competitive. Any large-scale solar project would require careful planning, environmental assessments, and coordination with local authorities and communities.
Additionally, the region's climate, with its moderate sunlight levels compared to southern France, means that solar installations may not be as efficient as in sunnier parts of the country. However, advances in solar technology continue to make projects viable even in areas with less optimal solar resources.
