Solar PV Analysis of Friesach, Austria
Friesach, Carinthia, Austria, situated at 46.955°N, 14.4085°E, presents a mixed landscape for solar energy generation throughout the year. This location in the Northern Temperate Zone experiences significant seasonal variations in solar output, which impacts the overall efficiency of photovoltaic (PV) systems.
Seasonal Solar Performance
The solar energy potential in Friesach fluctuates considerably across the seasons. Summer stands out as the most productive period, with an impressive daily output of 6.55 kWh per kW of installed solar capacity. Spring follows as the second-best season, generating 4.66 kWh/day. Autumn sees a notable decrease to 3.02 kWh/day, while winter experiences the lowest output at 1.84 kWh/day.
These figures highlight that the most ideal times for solar energy generation in Friesach are during the summer months and late spring. The extended daylight hours and higher sun angle during these periods contribute significantly to the increased energy production.
Optimizing Panel Installation
To maximize year-round solar energy production in Friesach, Carinthia, fixed solar panels should be installed at a tilt angle of 40 degrees facing south. This optimal angle has been calculated to capture the most sunlight throughout the year, considering the location's latitude and seasonal sun paths.
Environmental and Weather Considerations
While Friesach's location is generally favorable for solar energy, there are some environmental factors that could potentially impact solar production:
- Snow accumulation in winter months
- Occasional fog, especially in autumn and winter
To mitigate these issues, installing panels at the recommended 40-degree angle can help shed snow more easily. Additionally, using anti-reflective coatings on panels can improve performance during foggy conditions. Regular maintenance, including snow removal and cleaning, is crucial to ensure optimal energy production year-round.
In conclusion, while Friesach experiences significant seasonal variations in solar output, proper panel installation and maintenance can help maximize energy production, making solar PV a viable renewable energy option for this Austrian location.
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 124 locations across Austria. 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 Friesach
Seasonal solar PV output for Latitude: 46.955, Longitude: 14.4085 (Friesach, Austria), 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 Friesach, Austria
To maximize your solar PV system's energy output in Friesach, Austria (Lat/Long 46.955, 14.4085) 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 Friesach, Austria
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 Friesach, Austria. 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 | 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 Friesach, Austria
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 Friesach, Austria.
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 Friesach, Austria
The area around Friesach, Austria, is characterized by a diverse and picturesque topography typical of the eastern Alps region. Friesach itself is situated in a valley, nestled among rolling hills and surrounded by more dramatic mountainous terrain.
The immediate vicinity of Friesach features gentle slopes and undulating landscapes, with elevations gradually increasing as you move away from the town center. To the west and southwest, the terrain becomes more rugged, with steeper hillsides and forested areas. The eastern side of Friesach tends to be slightly flatter, with more open spaces and agricultural land.
As you venture further from Friesach, you'll encounter higher elevations and more pronounced mountain ranges. The Gurktal Alps lie to the northwest, while the Sau Alps can be found to the southeast. These mountain chains contribute to the region's varied topography, creating a mix of valleys, plateaus, and peaks.
Regarding areas suitable for large-scale solar PV installations, the most promising locations would likely be found in the more open, flatter areas to the east and northeast of Friesach. These regions tend to have gentler slopes and fewer obstructions, which are ideal conditions for solar farms. South-facing hillsides with moderate inclines could also be potential sites, as they would receive ample sunlight throughout the day.
However, it's important to note that the overall mountainous nature of the region may limit the availability of extensive, uninterrupted flat areas needed for very large solar installations. Any development would need to carefully consider the balance between optimal solar exposure and the preservation of the area's natural beauty and ecosystems.
Additionally, the valleys in the region, while potentially suitable in terms of space, may experience more shading from surrounding mountains, which could reduce their effectiveness for solar power generation. Therefore, site-specific assessments would be crucial to determine the most appropriate locations for solar PV projects in this topographically diverse area.
Austria solar PV Stats as a country
Austria ranks 28th in the world for cumulative solar PV capacity, with 2,692 total MW's of solar PV installed. This means that 3.40% of Austria's total energy as a country comes from solar PV (that's 25th in the world). Each year Austria is generating 302 Watts from solar PV per capita (Austria ranks 14th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Austria?
Yes, there are several incentives for businesses wanting to install solar energy in Austria. The Austrian government offers a range of financial support measures, including grants and loans, as well as tax breaks and other incentives. Additionally, the Austrian Energy Agency (AEA) provides information on funding opportunities for renewable energy projects.
