The location at Rotenburg an der Fulda, Hesse, Germany is in the Northern Temperate Zone and has varying levels of solar energy production throughout the year. During summer, you can expect around 5.25 kilowatt-hours (kWh) of electricity per day for each kilowatt (kW) of installed solar panels. This decreases to 2.34 kWh/day in autumn and further drops to 1.11 kWh/day during winter months. However, it increases again in spring with an output of about 4.29 kWh/day per kW.
To put it simply, this means that the best time for generating solar energy at this location is during summer and spring when sunlight is most abundant while autumn and especially winter are less ideal due to shorter days and less intense sunlight.
For fixed panel installations at this location, tilting the panels at a 43-degree angle towards the south will maximize total year-round production from solar photovoltaic (PV). This angle allows for optimal exposure to sunlight throughout different seasons.
As for environmental or local factors that could affect solar production here: Rotenburg an der Fulda experiences a temperate seasonal climate which means there might be periods with heavy cloud cover or rainfall which can reduce solar output significantly especially during autumn and winter months.
In terms of topography, if there are tall buildings or trees casting shadows on your panels that could also impede their efficiency by blocking direct sunlight.
To mitigate these issues: Firstly you should ensure your installation site is clear from any potential shading objects as much as possible; secondly using high-quality PV modules with good low-light performance can help maintain reasonable output even under sub-optimal light conditions; thirdly regular maintenance like cleaning off dust or snow from your panels can also help ensure they operate efficiently all year round.
So overall while not being perfect due to seasonal variations in weather conditions, Rotenburg an der Fulda still offers decent potential for solar energy production especially during summer and spring months with proper installation and maintenance.
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 Rotenburg An Der Fulda
Seasonal solar PV output for Latitude: 50.9978, Longitude: 9.7248 (Rotenburg An Der Fulda, 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 43° South in Rotenburg An Der Fulda, Germany
To maximize your solar PV system's energy output in Rotenburg An Der Fulda, Germany (Lat/Long 50.9978, 9.7248) throughout the year, you should tilt your panels at an angle of 43° 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 Rotenburg An Der Fulda, 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 Rotenburg An Der Fulda, Germany. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 43° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 34° South in Summer | 53° South in Autumn | 64° South in Winter | 43° 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 Rotenburg An Der Fulda, 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 Rotenburg An Der Fulda, 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 Rotenburg An Der Fulda, Germany
Rotenburg an der Fulda is located in the state of Hesse in central Germany. The town is situated on a hilly landscape, with the Fulda River flowing through it. The surrounding area is characterized by mixed forests, agricultural lands and small hills. The altitude varies between 200 to 400 meters above sea level.
The topography of the region could potentially support large-scale solar PV installations. Flat or gently sloping areas are ideal for such projects as they allow for easier installation and maintenance while maximizing sun exposure.
In terms of specific locations nearby that would be most suited for large-scale solar PV, this would likely be on cleared agricultural lands or other open spaces that receive ample sunlight throughout the year. Areas around Rotenburg an der Fulda which are less forested or have lower slopes might also be suitable.
However, factors beyond topography should also be considered when planning large-scale solar installations - these include local climate (amount of sunshine), proximity to power grids for easy transmission of electricity produced, land use regulations and environmental impact considerations among others.
For precise site selection and feasibility analysis, a detailed study involving GIS mapping techniques, ground surveys and consultation with local authorities & experts would typically be required.
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.
