Solar PV Analysis of Ebnat-Kappel, Switzerland
Ebnat-Kappel in Switzerland is a moderately good location for generating solar energy all year round. The amount of energy you can get from solar panels depends on how much sunlight they receive, measured in kilowatt hours per day (kWh/day) per kilowatt of installed solar.
In the summer, you can expect to generate about 5.71 kWh/day per kW of installed solar. This is the best time of year for generating solar energy at this location because the days are longest and the sun is at its highest point in the sky.
In autumn, production drops to around 2.99 kWh/day as days become shorter and there's less sunlight available. Winter sees an even larger drop, with only about 1.52 kWh/day being generated due to short days and low sun angles.
However, things start picking up again in spring with around 4.85 kWh/day expected as days lengthen and more sunlight becomes available.
For a fixed panel installation at this location, tilting your panels at an angle of 40 degrees towards South would maximise total year-round production from your solar PV system because it aligns better with the path that the sun takes across the sky throughout different seasons.
As for local factors that could affect solar production: Ebnat-Kappel lies within mountainous terrain which could potentially block some sunlight depending on specific site locations - so choosing a spot without obstructions would be beneficial if possible.
The region also experiences snowfall during winter months which could cover panels reducing their effectiveness - implementing measures such as installing snow guards or ensuring easy access for manual cleaning might help mitigate this issue if it proves significant enough to affect overall output levels significantly over time.
Lastly, while Switzerland generally has clean air quality; any potential local sources causing increased dust or air pollution might necessitate more frequent cleaning maintenance schedules to keep panel surfaces clear for maximum light absorption efficiency.
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 Ebnat-Kappel
Seasonal solar PV output for Latitude: 47.2468, Longitude: 9.1352 (Ebnat-Kappel, 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 Ebnat-Kappel, Switzerland
To maximize your solar PV system's energy output in Ebnat-Kappel, Switzerland (Lat/Long 47.2468, 9.1352) 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 Ebnat-Kappel, 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 Ebnat-Kappel, 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 Ebnat-Kappel, 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 Ebnat-Kappel, 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 Ebnat-Kappel, Switzerland
Ebnat-Kappel is located in the Toggenburg region of Switzerland, which is characterized by a hilly terrain with mountains and valleys. The area is surrounded by the Alpstein mountain range to the south and east, and the Thur river valley to the west. The town itself sits at an elevation of about 630 meters above sea level.
As for solar PV potential, it's important to note that while Switzerland receives less sunlight than countries closer to the equator, solar power can still be viable due to its efficient technology.
Flat areas are generally more suitable for large-scale solar installations due to easier installation and maintenance. However, given that Ebnat-Kappel is in a mountainous region, flat land might be limited. South-facing slopes could also be suitable as they would receive a good amount of sunlight throughout the day.
In terms of specific locations near Ebnat-Kappel for large-scale solar PV:
1) Flat areas along the Thur river valley could potentially be used.
2) South-facing slopes on hills or mountains could also be utilized.
3) Rooftops in urban or industrial areas can also serve as sites for smaller scale installations.
However, any decision on where exactly to place such an installation should take into account other factors like environmental impact (e.g., effect on local flora and fauna), proximity to power grids (for ease of feeding electricity into them), aesthetics (as large-scale solar farms can alter landscapes significantly), among others.
It's recommended that a thorough feasibility study including all these aspects should be conducted before deciding on any location.
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.
