Solar PV Analysis of Wiener Neustadt, Austria
Located in Wiener Neustadt, Lower Austria, Austria (latitude: 47.8044, longitude: 16.2489), the average solar energy generation per kilowatt of installed capacity varies significantly across the seasons. In summer, it averages at 6.66 kWh per day per kW due to longer daylight hours and higher intensity of sunlight; in autumn, this drops to an average of 3.04 kWh per day per kW as daylight hours decrease and cloud cover increases; in winter, the figure further reduces to an average of 1.55 kWh per day per kW owing to short days and low sunlight intensity; while spring sees a rise again with an average output of 4.69 kWh/day/kW due to increasing daylight hours and improving weather conditions.
The ideal tilt angle for fixed solar panel installations at this location is towards the South at a degree of approximately 40 degrees for optimum exposure to sunlight throughout the year.
Wiener Neustadt’s geographical position makes it suitable for harnessing solar power year-round despite seasonal variations in energy production levels. However, certain environmental factors could potentially impede optimal solar production here.
Heavy cloud cover during certain periods can obstruct direct sunlight from reaching the panels thereby reducing their output efficiency. Moreover, extreme temperatures can also affect performance as high temperatures can cause overheating leading to decreased efficiency while extremely low temperatures might lead to snow accumulation on panels which may block sunlight.
Preventative measures that could be taken into account during installation include installing panels on elevated structures or rooftops where they are less likely to be shaded by surrounding buildings or vegetation and ensuring sufficient ventilation around them for cooling purposes during hot weather conditions.
Also consider using advanced modules designed with better temperature coefficients that perform well under high temperature conditions; or even heated panels capable of melting any accumulated snow during winter months would help ensure greater energy production all year round despite these environmental challenges.
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 Wiener Neustadt
Seasonal solar PV output for Latitude: 47.8044, Longitude: 16.2489 (Wiener Neustadt, 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 Wiener Neustadt, Austria
To maximize your solar PV system's energy output in Wiener Neustadt, Austria (Lat/Long 47.8044, 16.2489) 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 Wiener Neustadt, 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 Wiener Neustadt, 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 |
|---|---|---|---|
| 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 Wiener Neustadt, 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 Wiener Neustadt, 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 Wiener Neustadt, Austria
The topography around Wiener Neustadt is mostly flat, with some rolling hills and low mountains in the distance. The area is well suited for large-scale solar PV installations due to its large open spaces and direct sunlight exposure. Areas that would be most suitable include the flat plains to the east of the city, as well as any south-facing slopes or hilltops in the surrounding countryside.
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.
