Solar PV Analysis of Gerlafingen, Switzerland
Gerlafingen, Solothurn, Switzerland is a location that could generate a reasonable amount of solar energy throughout the year, with some variation across seasons. In simple terms, for every kilowatt of solar power equipment you install there, you can expect to produce an average of 5.74 kilowatt-hours (kWh) per day in the summer season. This output drops to around 3.02 kWh/day in autumn and further decreases to about 1.45 kWh/day during winter months due to shorter daylight hours and lower sun intensity. However, it picks up again in spring with an average production of about 4.89 kWh/day.
The best time for generating solar energy at this location would be during the summer when sunlight is most abundant followed by springtime because these periods provide longer daylight hours and higher sun intensity compared to other times of the year.
To get the most out of your solar panels all year round at this location, they should ideally be installed at a tilt angle facing southwards towards 40 degrees from horizontal level; this ensures maximum exposure to sunlight over different seasons.
However, there are several factors that could potentially hinder optimal solar production at Gerlafingen:
1) Weather conditions like snowfall or heavy rainfall might obstruct panels or reduce their efficiency.
2) The region's temperate climate may result in fewer sunny days compared to more arid regions.
3) Local buildings or vegetation might cast shadows on the panels reducing their exposure to direct sunlight.
To counteract these potential issues:
1) Regular maintenance including cleaning off any snow or debris from panels will help maintain efficiency.
2) Choosing high-quality PV systems designed for variable weather conditions can also improve overall performance.
3) Careful site selection and positioning can avoid shadows impeding panel exposure where possible.
Remember though while these measures can enhance performance they may not completely eliminate all environmental impacts on your system's productivity but will certainly help make the most of it.
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 Gerlafingen
Seasonal solar PV output for Latitude: 47.1725, Longitude: 7.5763 (Gerlafingen, 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 Gerlafingen, Switzerland
To maximize your solar PV system's energy output in Gerlafingen, Switzerland (Lat/Long 47.1725, 7.5763) 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 Gerlafingen, 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 Gerlafingen, 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 Gerlafingen, 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 Gerlafingen, 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 Gerlafingen, Switzerland
Gerlafingen is located in the canton of Solothurn, Switzerland. The topography around Gerlafingen is characterized by a mix of flat plains and hilly terrain. It's located near the Swiss Plateau region which is known for its fertile lands and gentle slopes.
The best areas for large-scale solar PV installations would be on south-facing slopes that receive ample sunlight throughout the year. These could potentially include agricultural lands or open fields that are not shaded by mountains or forests. Also, rooftops of large industrial buildings in this area can be considered as potential sites for installing solar panels.
However, it's important to note that while these general guidelines apply, specific site selection would require a detailed analysis considering several factors such as local weather patterns, land use restrictions, proximity to power grids and infrastructure among others. Furthermore, environmental impact assessments might also need to be conducted depending on local regulations and policies regarding renewable energy projects.
In terms of nearby areas suited for large-scale solar PV installations:
1) Flatlands along the Aare River could potentially serve as good locations given their exposure to sunlight.
2) Areas around neighboring towns like Subingen or Deitingen which have relatively flat terrains.
3) Large industrial zones in regions like Derendingen or Zuchwil could also provide suitable rooftop spaces for setting up solar panels.
Remember though that any such development needs careful planning and consideration of ecological aspects too!
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.
