Solar PV Analysis of Root, Switzerland
Root, Lucerne, Switzerland, situated at 47.1176° N latitude and 8.3876° E longitude, presents a mixed scenario for solar PV energy generation throughout the year. This location in the Northern Temperate Zone experiences significant seasonal variations in solar energy production.
Seasonal Solar Performance
Summer stands out as the most productive season, with an impressive daily output of 5.71 kWh per kW of installed solar capacity. Spring follows closely, generating 4.85 kWh/day. However, autumn sees a considerable drop to 2.99 kWh/day, while winter performance plummets to a mere 1.52 kWh/day.
These figures highlight the stark contrast between the warmer and colder months, with summer producing nearly four times the energy of winter. This disparity underscores the challenges of relying solely on solar power in Root throughout the year.
Optimal Panel Positioning
To maximize year-round solar energy production in Root, Lucerne, fixed solar panels should be tilted at a 40-degree angle facing south. This orientation helps capture the most sunlight across all seasons, balancing the low winter sun with the high summer sun.
Environmental and Weather Factors
Several factors can impact solar production in Root:
- Snow accumulation in winter can significantly reduce panel efficiency
- Fog and cloud cover, common in the region, may decrease solar irradiance
To mitigate these issues, consider installing panels at a steeper angle to promote snow sliding off. Additionally, using high-efficiency panels and incorporating a robust cleaning routine can help maintain optimal performance despite challenging weather conditions.
Conclusion
While Root's location is not ideal for year-round solar energy production, it still offers substantial potential, especially during spring and summer. By implementing appropriate panel positioning and maintenance strategies, residents can effectively harness solar power to supplement their energy needs, particularly during the more productive months of the year.
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 Root
Seasonal solar PV output for Latitude: 47.1176, Longitude: 8.3876 (Root, Switzerland), 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 40° South in Root, Switzerland
To maximize your solar PV system's energy output in Root, Switzerland (Lat/Long 47.1176, 8.3876) 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 Root, 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 Root, 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 | 50° South in Autumn | 61° 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 Root, 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 Root, 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 Root, Switzerland
The area around Root, Switzerland is characterized by diverse and picturesque topography typical of the Swiss Pre-Alps region. Located in the canton of Lucerne, Root sits in a valley surrounded by rolling hills and low mountains. The landscape is a mix of gentle slopes, small plateaus, and steeper inclines as you move away from the town center.
To the north and east of Root, the terrain gradually rises towards the Rooterberg, a modest hill that offers panoramic views of the surrounding countryside. The southern and western sides of the town are bordered by the Reuss River valley, which provides a relatively flat expanse along its banks. As you move further from the river, the land begins to undulate more noticeably, with a series of hills and small valleys creating a patchwork of fields, forests, and scattered settlements.
In terms of large-scale solar PV installations, the most suitable areas nearby would likely be found on the gentler slopes and plateaus to the north and east of Root. These areas offer several advantages for solar energy production:
- They have a southerly aspect, which is ideal for maximizing sun exposure throughout the day.
- The moderate inclines can help with natural cooling of solar panels, improving their efficiency.
- These locations are generally less forested than the steeper mountainsides, reducing the need for extensive land clearing.
- The elevated positions may experience less fog and cloud cover compared to the valley floor, potentially increasing the amount of sunlight received.
However, it's important to note that large-scale solar installations would need to be carefully planned and implemented to minimize their impact on the local environment and scenery. Switzerland has strict regulations regarding land use and environmental protection, so any proposed solar projects would need to undergo thorough assessment and approval processes.
The flatter areas along the Reuss River valley might also be considered for solar PV, but these locations may be more valuable for agriculture or face a higher risk of flooding. Additionally, they may experience more frequent fog or mist due to their proximity to the river, which could reduce solar efficiency.
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. This means that 4.70% of Switzerland's total energy as a country comes from solar PV (that's 16th in the world). Each year Switzerland is generating 399 Watts from solar PV per capita (Switzerland ranks 6th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Switzerland?
