Solar PV Analysis of Lucerne, Switzerland
The location in Lucerne, Switzerland is moderately ideal for generating energy via solar photovoltaic (PV) panels. The amount of electricity that can be produced varies throughout the year, with the summer and spring seasons being the most productive. Specifically, during summer you can expect to generate around 5.71 kilowatt-hours (kWh) per day for each kilowatt (kW) of installed solar power. In spring, this figure is slightly less at approximately 4.85 kWh/day per kW.
However, output decreases significantly in autumn and winter, producing only around 2.99 kWh/day per kW and 1.52 kWh/day per kW respectively due to shorter daylight hours and lower sun angles.
For optimal performance year-round at this location, it's recommended that fixed solar panels are tilted towards the south at an angle of about 40 degrees. This would help maximize exposure to sunlight throughout all four seasons.
As for environmental or weather factors that could affect solar production in Lucerne; cloud cover can reduce the amount of sunlight reaching your panels thus decreasing their efficiency - especially during autumn and winter when skies tend to be more overcast compared with other seasons.
Snowfall could also impede solar production as it may cover your panels reducing their exposure to sunlight - a common issue during wintertime in Switzerland which receives significant snowfall annually.
To counter these potential issues, regular maintenance including cleaning off any accumulated dust or debris from your panels should be performed regularly - more so after snowfalls or storms which might leave residue on your panel surfaces obstructing them from receiving direct sunlight efficiently.
Consideration could also be given towards installing adjustable mounting systems allowing you to manually change your panel angles depending on seasonality ensuring maximum sun exposure regardless of time of year but this would come with additional costs compared against fixed tilt installations which are typically cheaper overall due its simpler design structure.
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.

Solar output per kW of installed solar PV by season in Lucerne
Seasonal solar PV output for Latitude: 47.0511, Longitude: 8.3056 (Lucerne, 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 Lucerne, Switzerland
To maximize your solar PV system's energy output in Lucerne, Switzerland (Lat/Long 47.0511, 8.3056) 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 Lucerne, 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 Lucerne, 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 Lucerne, 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 Lucerne, 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 Lucerne, Switzerland
Lucerne is located in central Switzerland and is surrounded by mountains. The city itself is situated on the shores of Lake Lucerne and the Reuss River, with a mixture of flat and hilly terrain.
The topography around Lucerne includes valleys, plateaus, hills, and high mountain ranges such as Pilatus and Rigi. These mountains have altitudes reaching over 2,000 meters above sea level. This kind of terrain can be challenging for large-scale solar PV installations due to shadowing effects from the mountains and difficulty in installation on steep slopes.
However, there are still opportunities for solar energy production in this region:
1) Rooftop Solar Installations: Given the urban nature of Lucerne city itself, rooftop solar installations could be an ideal solution. Buildings offer flat surfaces that can be used to install photovoltaic panels without any major geographical constraints.
2) Floating Solar Farms: Given its location near Lake Lucerne (Vierwaldstättersee), floating solar farms could also be considered. They have been successfully implemented in other locations across the world where land availability is a concern.
3) Mountain Solar Farms: Although installing solar panels on mountain sides can be challenging due to slope angles and potential shading issues, it's not impossible if properly designed taking into account optimal orientation towards sun path.
4) Farmland or Open Fields: Areas outside the city that are relatively flat like farmlands or open fields would also provide suitable locations for large scale ground-mounted PV systems.
In terms of sunlight availability which influences productivity of a PV system; although Switzerland does not receive as much sunlight compared to countries closer to equator but it still receives enough sunlight throughout year making it viable for solar power generation.
To determine most suited areas nearby with precision though would require detailed analysis including aspects like local weather patterns (solar irradiance levels), land use restrictions/regulations among others along with topographical considerations mentioned above.
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?
Yes, there are several incentives for businesses wanting to install solar energy in Switzerland. The Swiss Federal Office of Energy (SFOE) offers a range of financial support measures for businesses that want to invest in renewable energy sources such as solar power. These include grants, loans and tax deductions. Additionally, the Swiss government has set up a feed-in tariff system which guarantees a fixed price for electricity generated from renewable sources such as solar power. This helps to make investing in solar energy more attractive for businesses.
