Solar PV Analysis of Hunenberg, Switzerland
In Hunenberg, Zug, Switzerland (latitude: 47.1937, longitude: 8.4202), solar power generation is viable throughout the year due to its varying average daily solar irradiance per kW of installed solar capacity across different seasons: 5.71 kWh in Summer, 2.99 kWh in Autumn, 1.52 kWh in Winter, and 4.85 kWh in Spring. The highest energy production occurs during the summer months when sunlight is more abundant and cloud coverage is minimal.
However, certain factors such as heavy rain or snowfall can negatively impact solar power generation by reducing the amount of sunlight available for energy production. To optimize energy output at this location, it is recommended to install fixed solar panels at a tilt angle of 40 degrees facing south.
To mitigate potential issues caused by environmental factors like snow accumulation on panels during winter months, regular maintenance and cleaning should be performed to ensure maximum exposure to sunlight and efficient energy production throughout the year.
Overall, Hunenberg's location offers suitable conditions for generating solar power year-round with proper installation and maintenance practices in place to address any local challenges that may arise due to weather or topographical factors.
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 Hunenberg
Seasonal solar PV output for Latitude: 47.1937, Longitude: 8.4202 (Hunenberg, 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 Hunenberg, Switzerland
To maximize your solar PV system's energy output in Hunenberg, Switzerland (Lat/Long 47.1937, 8.4202) 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 Hunenberg, 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 Hunenberg, 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 |
|---|---|---|---|
| 31° South in Summer | 50° South in Autumn | 61° South in Winter | 40° 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 Hunenberg, 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 Hunenberg, 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 Hunenberg, Switzerland
The topography around Hunenberg, Switzerland is generally quite flat, with some rolling hills and low mountains in the distance. The area is also surrounded by large bodies of water such as Lake Hallwil and the Aabach river. This makes it an ideal location for solar PV installations since there are no large obstructions that would block sunlight from reaching the ground. Areas to the south and east of Hunenberg would be most suitable for large-scale solar PV installations due to their relative flatness and lack of obstructions from nearby buildings or trees.
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.
