Solar PV Analysis of Tuttlingen, Germany
Tuttlingen, Germany (latitude: 47.9863, longitude: 8.819) offers a suitable environment for solar power generation throughout the year, with varying levels of solar energy production across the seasons. During summer months, the average energy output reaches its peak at 5.71 kWh per day per kW of installed solar capacity. Spring also provides favorable conditions with an average daily output of 4.85 kWh per kW.
In contrast, autumn and winter see lower levels of solar energy production in Tuttlingen due to shorter daylight hours and less sunlight intensity; nevertheless, they still offer a reasonable amount of power generation at an average daily rate of 2.99 kWh per kW in autumn and 1.52 kWh per kW in winter.
To maximize efficiency for fixed panel installations in this location, it is recommended to tilt panels at an angle of approximately 41 degrees facing southward to capture optimal sunlight exposure throughout the year.
However, certain local factors may impact solar production in Tuttlingen such as cloudy weather or snowfall during winter months which can obstruct sunlight from reaching the panels effectively or even cover them entirely if not properly maintained during these periods.
To mitigate these factors and ensure greater energy production from your solar installation:
1) Regularly monitor weather forecasts and plan maintenance accordingly.
2) Implement snow removal measures such as using soft brushes or leaf blowers on a regular basis during snowy periods.
3) Consider installing micro-inverters instead of central inverters since they allow each panel to operate independently which helps minimize any losses due to shading or snow coverage on some panels while others remain unobstructed.
4) Optimize panel placement by avoiding areas prone to shade or other obstructions caused by nearby buildings or vegetation growth.
Overall, Tuttlingen's location provides a viable option for generating solar power throughout the year with proper planning and maintenance measures taken into account when installing a PV system there.
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 Tuttlingen
Seasonal solar PV output for Latitude: 47.9863, Longitude: 8.819 (Tuttlingen, 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 Tuttlingen, Germany
To maximize your solar PV system's energy output in Tuttlingen, Germany (Lat/Long 47.9863, 8.819) 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 Tuttlingen, 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 Tuttlingen, 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 |
|---|---|---|---|
| 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 Tuttlingen, 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 Tuttlingen, 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 Tuttlingen, Germany
The topography around Tuttlingen, Germany is generally hilly and mountainous. The highest peak in the area is the Hohenzollernberg at 875 meters above sea level. Areas to the south and east of Tuttlingen are more flat and would be most suitable for large-scale solar PV installations. These areas have ample amounts of sun exposure and lack obstructions such as trees or buildings that could block sunlight from reaching panels.
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.
