Solar PV Analysis of Pratteln, Switzerland
Pratteln, Switzerland, situated in the Northern Temperate Zone, can be a decent location for generating solar energy throughout the year. However, the amount of electricity produced will vary greatly depending on the season.
During summer and spring months (when days are longer and sunlight is more direct), solar panels can generate a good amount of electricity - about 5.74 kilowatt-hours (kWh) per day in summer and 4.89 kWh/day in spring for each kilowatt (kW) of installed solar power.
In contrast, during autumn and winter months (when days are shorter and sunlight is less direct), you'll see less energy production - approximately 3.02 kWh/day in autumn and only 1.45 kWh/day in winter per kW of installed solar power.
To make sure that your solar panels produce as much energy as possible all year round at this location, they should ideally be tilted at an angle facing south by 41 degrees. This position allows them to capture maximum sunlight over different seasons.
However, there could be local factors that might affect how much sun your panels get such as weather conditions or environmental elements like mountains or tall buildings casting shadows over your installation site.
Switzerland generally has a temperate climate but it does experience cloudy days especially during winter which could reduce the efficiency of your panels significantly during those times.
Also consider snowfall which may cover up your panels reducing their effectiveness or even causing damage if not managed properly; hence it's important to have measures in place for safely removing snow from your system without damaging it.
To help ensure greater energy production despite these potential obstacles:
1) Make sure to install your system where there's minimal shading from surrounding structures.
2) Regularly clean & maintain your system including safe removal of snowfall.
3) Consider having adjustable tilt systems so you can change panel angles seasonally for optimal exposure.
4) Use high-quality efficient panels that can still produce decent energy even on less sunny days.
In conclusion, while Pratteln, Switzerland is not the most ideal location for solar energy production due to its seasonal variations and potential weather challenges, with proper planning and maintenance it's definitely a viable option.
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 Pratteln
Seasonal solar PV output for Latitude: 47.5318, Longitude: 7.6911 (Pratteln, 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 41° South in Pratteln, Switzerland
To maximize your solar PV system's energy output in Pratteln, Switzerland (Lat/Long 47.5318, 7.6911) throughout the year, you should tilt your panels at an angle of 41° 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 Pratteln, 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 Pratteln, Switzerland. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 41° 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 | 51° 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 Pratteln, 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 Pratteln, 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 Pratteln, Switzerland
Pratteln is located in the Basel-Landschaft Canton of Switzerland. The topography around the town is characterized by a mix of flat plains, gentle slopes and hilly terrain with some forested areas. The Rhine River flows nearby, adding to the region's diverse landscape.
The most suitable areas for large-scale solar photovoltaic (PV) installations would be flat open spaces or south-facing slopes that receive plenty of sunlight throughout the year. Given Pratteln's location near industrial zones and its extensive railway infrastructure, rooftops of large buildings such as warehouses or factories could also potentially serve as sites for solar PV systems.
It should be noted that any development must adhere to local regulations and environmental considerations, including preserving the natural beauty and biodiversity of Switzerland’s landscapes. Therefore, detailed feasibility studies would need to be carried out before selecting specific sites for large-scale solar PV installations.
Moreover, because Switzerland lies at higher latitudes where sunlight can be less intense compared to more equatorial regions, efficiency of solar panels might not be as high as in other locations worldwide. However, advancements in technology are improving panel efficiency even under less ideal conditions.
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.
