Solar PV Analysis of Ulm, Germany
Situated in Ulm, Germany (latitude: 48.3957, longitude: 9.9956), the potential for solar photovoltaic (PV) power generation is rather promising. The average energy production per kilowatt of installed solar capacity varies with the seasons – it is highest in summer at 5.59 kWh per day, followed by spring at 4.56 kWh per day, autumn at 2.81 kWh per day and winter at a lower value of 1.37 kWh per day.
The higher energy yields during the summer and spring months are attributable to longer daylight hours and enhanced sunlight exposure characteristic of these seasons in this region located within the Northern Temperate Zone.
Nevertheless, local weather conditions could pose challenges to optimal solar power generation here in Ulm - a city known for its temperate climate with cooler temperatures prevailing most of the year compared to other global regions. Precipitation events such as rain or snow can obstruct sunlight reaching solar panels thereby affecting their performance.
To circumvent these potential impediments and ensure greater energy production throughout the year irrespective of seasonal variations, specific measures can be adopted during installation phase itself - such as positioning panels at an ideal tilt angle towards South which has been identified as being approximately 41 degrees for this location.
This strategic orientation would not only maximize exposure to direct sunlight throughout varied sun paths over different seasons but also help shed off any accumulated snow on panel surfaces during winter months thereby minimizing any consequent decrease in efficiency due to shading effects or reduced surface area for light capture.
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 Ulm
Seasonal solar PV output for Latitude: 48.3957, Longitude: 9.9956 (Ulm, 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 Ulm, Germany
To maximize your solar PV system's energy output in Ulm, Germany (Lat/Long 48.3957, 9.9956) 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 Ulm, 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 Ulm, 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 Ulm, 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 Ulm, 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 Ulm, Germany
The topography around Ulm, Germany is relatively flat with some rolling hills. The areas most suited to large-scale solar PV would be the flat plains and open fields near the city. Additionally, any south-facing slopes or hilltops in the area could also be good sites for solar installations.
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.
