Solar PV Analysis of Hagenbrunn, Austria
Hagenbrunn, Lower Austria, Austria, situated at 48.3293° N, 16.4007° E, presents a mixed picture for solar PV energy generation throughout the year. Located in the Northern Temperate Zone, this area experiences significant seasonal variations in solar output.
Seasonal Solar Performance
Summer stands out as the most productive season, with an impressive 6.42 kWh per day for each kW of installed solar capacity. Spring follows as the second-best season, yielding 4.55 kWh/day. However, the output drops considerably during autumn, producing only 2.87 kWh/day. Winter sees the lowest generation, with a mere 1.29 kWh/day.
These figures highlight the stark contrast between summer and winter performance, with summer generating nearly five times more energy than winter. The substantial difference underscores the importance of carefully planning for year-round energy needs in this location.
Optimal Panel Positioning
To maximize year-round solar production in Hagenbrunn, Lower Austria, fixed solar panels should be tilted at a 41-degree angle facing south. This optimal angle takes into account the location's latitude and the Earth's elliptical orbit, ensuring the best possible exposure to sunlight throughout the year.
Environmental Considerations
While Hagenbrunn doesn't face any major environmental obstacles to solar production, there are some factors to consider:
- Snow accumulation in winter can temporarily reduce panel efficiency
- Occasional fog, particularly in autumn and winter, may slightly decrease solar irradiance
To mitigate these issues, installing panels at the recommended 41-degree tilt can help snow slide off more easily. Additionally, using high-quality, anti-reflective glass on the panels can improve performance in foggy conditions. Regular maintenance, including snow removal when necessary, will also help ensure optimal energy production year-round.
In conclusion, while Hagenbrunn's location is not ideal for consistent year-round solar production due to significant seasonal variations, proper panel positioning and maintenance can still make solar PV a viable energy option, especially during the more productive spring and summer months.
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 Hagenbrunn
Seasonal solar PV output for Latitude: 48.3293, Longitude: 16.4007 (Hagenbrunn, 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 41° South in Hagenbrunn, Austria
To maximize your solar PV system's energy output in Hagenbrunn, Austria (Lat/Long 48.3293, 16.4007) 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 Hagenbrunn, 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 Hagenbrunn, Austria. 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 |
|---|---|---|---|
| 32° South in Summer | 51° South in Autumn | 62° South in Winter | 41° 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 Hagenbrunn, 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 Hagenbrunn, 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 Hagenbrunn, Austria
The area around Hagenbrunn, Austria, is characterized by a diverse topography that reflects its location on the eastern edge of the Alps and the beginning of the Pannonian Basin. The landscape is a mix of gently rolling hills, shallow valleys, and some flatter areas as you move eastward.
To the west of Hagenbrunn, the terrain becomes more elevated and hilly, with the foothills of the Alps beginning to rise. These hills are often covered in forests or vineyards, taking advantage of the sloping terrain. As you move east and southeast from Hagenbrunn, the land gradually becomes flatter, transitioning into the Pannonian Plain.
The nearby Danube River has played a significant role in shaping the local topography, creating a broad river valley with fertile floodplains. This area is known for its agricultural productivity, with many fields and orchards dotting the landscape.
For large-scale solar PV installations, the most suitable areas would likely be found to the east and southeast of Hagenbrunn. These regions tend to have flatter terrain, which is ideal for solar farms as it reduces the cost and complexity of installation. The open agricultural lands in this direction would provide ample space for solar panels without significant topographical obstacles.
However, it's important to note that the suitability of an area for solar PV isn't solely determined by topography. Other factors such as sun exposure, local climate conditions, proximity to power infrastructure, and land use regulations also play crucial roles. While the flatter areas east of Hagenbrunn may be topographically suitable, a comprehensive assessment would be necessary to determine the best locations for large-scale solar PV projects in the region.
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. Furthermore, businesses can benefit from the Feed-in Tariff (FiT), which guarantees a fixed price for electricity generated from renewable sources such as solar energy.
