Meyrin, Geneva, Switzerland, situated at 46.2356°N, 6.0747°E, presents a mixed landscape for solar PV energy generation throughout the year. This location in the Northern Temperate Zone experiences significant seasonal variations in solar output, which directly impacts the efficiency of photovoltaic systems.
Seasonal Solar Performance
The solar energy potential in Meyrin fluctuates considerably across the seasons. Summer stands out as the most productive period, with an impressive daily output of 6.00 kWh per kW of installed solar capacity. Spring follows as the second most favorable season, generating 4.89 kWh/day. Autumn sees a notable decrease to 3.09 kWh/day, while winter experiences the lowest output at just 1.58 kWh/day.
These figures highlight that the most ideal times for solar energy generation in Meyrin are during the summer months and late spring. During these periods, longer daylight hours and higher sun angles contribute to increased solar panel efficiency.
Optimizing Panel Installation
To maximize year-round solar production in Meyrin, Geneva, fixed solar panels should be installed at a tilt angle of 40 degrees facing south. This optimal angle has been calculated to balance the varying sun positions throughout the year, ensuring the best possible energy capture across all seasons.
Environmental and Weather Considerations
While Meyrin's location is generally favorable for solar energy, there are some environmental factors to consider. The region experiences a moderate amount of cloudy days, particularly in winter, which can reduce solar output. Additionally, snowfall during winter months may temporarily cover panels, impeding energy production.
To mitigate these issues, several preventative measures can be implemented: 1. Use self-cleaning panels or regular maintenance to remove snow buildup. 2. Install panels at a steeper angle to encourage snow sliding off. 3. Employ high-efficiency panels that perform better in low-light conditions. 4. Consider a ground-mounted system for easier access and maintenance.
By addressing these factors, solar installations in Meyrin can be optimized to harness the maximum available solar energy throughout the year, despite the seasonal variations and occasional weather-related challenges.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 245 locations across Switzerland. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Ideally tilt fixed solar panels 40° South in Meyrin, Switzerland
To maximize your solar PV system's energy output in Meyrin, Switzerland (Lat/Long 46.2356, 6.0747) throughout the year, you should tilt your panels at an angle of 40° 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 Meyrin, Switzerland
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 Meyrin, Switzerland. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 40° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 30° South in Summer | 49° South in Autumn | 60° South in Winter | 39° 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 Meyrin, Switzerland
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 Meyrin, Switzerland.
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 Meyrin, Switzerland
Meyrin, Switzerland, situated near the French border, is characterized by a diverse topography that reflects its location at the junction of several distinct landscapes. The area around Meyrin is primarily composed of gently rolling hills and plateaus, with elevations ranging from approximately 400 to 500 meters above sea level. To the east of Meyrin, the land gradually slopes down towards the Geneva basin and Lake Geneva. This area is relatively flat, with some minor undulations, and is largely urbanized as it approaches the city of Geneva. The western side of Meyrin features more pronounced hills that rise towards the Jura Mountains, creating a more varied terrain with some steeper slopes and small valleys. The northern part of Meyrin's surroundings is marked by a mix of agricultural fields and scattered woodlands, with the landscape becoming more rural as it extends away from the urban center. To the south, the terrain is generally flatter, transitioning into the Geneva airport area and its associated infrastructure.
Potential for Large-Scale Solar PV
When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The ideal locations would combine favorable topography, adequate sunlight exposure, and minimal conflict with existing land uses or protected areas. The relatively flat areas to the east and south of Meyrin present promising opportunities for solar PV development. These regions offer large, open spaces with minimal shading from natural features, which is crucial for maximizing solar energy capture. The gently sloping terrain in these areas could also provide a slight advantage in terms of panel orientation towards the sun. Agricultural lands to the north of Meyrin might also be considered for solar PV installations, particularly if implemented through agrivoltaic systems that allow for dual land use. However, this would require careful planning to balance energy production with agricultural needs. The hilly areas to the west, while potentially offering good sun exposure on south-facing slopes, may present challenges in terms of accessibility and construction. These areas might be better suited for smaller, distributed solar installations rather than large-scale projects. It's important to note that any large-scale solar PV development in the region would need to carefully consider local regulations, environmental impact, and the proximity to existing power infrastructure. The area's proximity to Geneva Airport would also necessitate evaluations to ensure that solar installations do not interfere with aviation activities.Switzerland solar PV Stats as a country
Switzerland ranks 25th in the world for cumulative solar PV capacity, with 3,449 total MW's of solar PV installed.
