Solar PV Analysis of Ostfildern, Germany
The area of Ostfildern, Baden-Wurttemberg, Germany is fairly suitable for generating solar energy throughout the year. However, it's not ideal all year round due to seasonal variations in sunlight exposure.
During summer and spring, you can expect a decent amount of electricity from your solar panels - about 5.59 kilowatt-hours (kWh) per day in summer and 4.56 kWh/day in spring per kilowatt of installed solar power capacity.
However, during autumn and winter the output drops significantly because these seasons have less daylight hours and more cloudy days. You can expect around 2.81 kWh/day in autumn and only 1.37 kWh/day in winter per kW of installed solar.
To get the most out of your solar panels throughout the year at this location, they should be tilted at an angle of 41 degrees facing southwards for a fixed panel installation.
As far as local factors that could affect solar production here go: weather is definitely one to consider since Germany experiences quite a bit of cloud cover especially during autumn and winter months which could reduce sunlight availability for your panels.
To counteract this issue when installing your system, you might want to consider using advanced PV modules designed specifically for low-light conditions or even integrate battery storage systems so excess energy produced during sunnier periods can be stored and used when production dips due to weather conditions.
It's also worth noting that any nearby buildings or trees that cast shadows on your panels will also negatively impact their performance so ensure clear access to direct sunlight where possible when choosing where on your property to install them.
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 919 locations across Germany. 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 Ostfildern
Seasonal solar PV output for Latitude: 48.7298, Longitude: 9.2541 (Ostfildern, Germany), 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 Ostfildern, Germany
To maximize your solar PV system's energy output in Ostfildern, Germany (Lat/Long 48.7298, 9.2541) 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 Ostfildern, Germany
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 Ostfildern, Germany. 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 Ostfildern, Germany
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 Ostfildern, Germany.
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 Ostfildern, Germany
Ostfildern, Germany is located in the southwestern part of the country, in a region characterized by a mix of flatlands and low-lying hills. The city itself is located on relatively flat terrain but it's surrounded by more hilly areas. This type of topography can be suitable for solar PV installations.
For large-scale solar PV projects, flat or gently sloping lands are preferable as they require less site preparation and can accommodate more panels per unit area. Areas with southern exposure (in the Northern Hemisphere) are also ideal as they receive the most sunlight throughout the day.
In Ostfildern and its surrounding regions, potential sites for large-scale solar PV could include:
1. Unused agricultural lands: These usually have good sun exposure and are relatively flat.
2. Industrial zones: Rooftops of factories or warehouses can be used to install solar panels.
3. Brownfield sites: These are former industrial sites that have been abandoned or underused.
4. Along transportation corridors such as highways or rail lines.
However, it's important to note that feasibility also depends on other factors such as local legislation regarding land use, proximity to power grids for easy connection and distribution of generated electricity, environmental impact assessments etc.
Additionally, Germany has a high latitude which means less sunlight during winter months compared to countries closer to equator - this needs to be factored into calculations about potential energy generation from any proposed solar installation there.
Finally one should conduct detailed site surveys using tools like GIS mapping and satellite imagery along with ground-based assessments before deciding upon any particular location for setting up a large scale photovoltaic plant.
Germany solar PV Stats as a country
Germany ranks 4th in the world for cumulative solar PV capacity, with 58,461 total MW's of solar PV installed. This means that 9.70% of Germany's total energy as a country comes from solar PV (that's 3rd in the world). Each year Germany is generating 702 Watts from solar PV per capita (Germany ranks 3rd in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Germany?
Yes, there are a few incentives for businesses wanting to install solar energy in Germany. These include feed-in tariffs, which guarantee businesses a price per kilowatt hour of electricity produced from their solar system; tax incentives such as the reduction of corporate income taxes; and subsidies from regional governments or utilities. Additionally, Germany's Renewable Energy Sources Act (EEG) provides additional support for projects that involve renewable energies.
