Solar PV Analysis of Riedstadt, Germany
Riedstadt, Hesse, Germany, situated at a latitude of 49.8356 and longitude of 8.5063, is a suitable location for generating solar power, though energy production will vary depending on season, due to its position in the Northern Temperate Zone.
This region experiences increased sunlight hours during the summer and spring months, resulting in an average daily energy production of 5.55 kWh per kW of installed solar capacity in summer and 4.57 kWh per kW in spring. In autumn there is an average 2.59kWh/day per kW of installed solar and in winter the production drops to 1.24 kWh/day per kW of installed solar.
It is recommended that panels be tilted at an angle of 42 degrees facing south to capture as much year-round energy from the sun as possible.
While Riedstadt's overall potential for solar power generation is promising, certain factors such as heavy cloud cover or snowfall can impact energy production from photovoltaic systems. To mitigate these effects, regular maintenance and cleaning of solar panels can help ensure optimal performance and greater energy production.
In conclusion, Riedstadt offers a favorable environment for harnessing solar power year-round with appropriate panel installation and maintenance measures in place to address local weather conditions that may impede energy production.
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 Riedstadt
Seasonal solar PV output for Latitude: 49.8356, Longitude: 8.5063 (Riedstadt, 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 42° South in Riedstadt, Germany
To maximize your solar PV system's energy output in Riedstadt, Germany (Lat/Long 49.8356, 8.5063) throughout the year, you should tilt your panels at an angle of 42° 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 Riedstadt, 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 Riedstadt, Germany. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 42° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 33° South in Summer | 52° South in Autumn | 63° South in Winter | 42° 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 Riedstadt, 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 Riedstadt, 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 Riedstadt, Germany
The topography around Riedstadt, Germany is mostly flat with some rolling hills. The terrain is generally low-lying and the highest elevation in the area is approximately 150 meters above sea level. The surrounding land is predominantly agricultural, with a few scattered forests and villages. Areas that are most suited to large-scale solar PV installations would be open fields or other areas of flat terrain with good access to sunlight.
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.
