Solar PV Analysis of Dreieich, Germany
The location at Dreieich, Hesse, Germany is fairly decent for generating energy through solar photovoltaic (PV) panels, although it's not the most ideal. The amount of energy you can get from solar panels depends on how much sunlight they receive. In Dreieich, Hesse, the sunlight varies quite a bit throughout the year.
During the summer months, you can expect to generate about 5.25 kilowatt-hours (kWh) per day for each kilowatt (kW) of solar panels installed. This is when you'll get the most energy from your solar panels due to longer daylight hours and higher sun position in the sky.
In autumn, this drops down to around 2.34 kWh per day per kW installed because days are shorter and sun rays hit at a lower angle.
Winter sees further reduction with only about 1.11 kWh generated per day per kW installed due to shorter days and often overcast skies in this part of Germany.
Springtime brings improvement with approximately 4.29 kWh generated daily for every kW of installed capacity as daylight hours increase again and weather conditions improve.
To maximize total year-round production from solar PV in Dreieich, Hesse, it's recommended that fixed panel installations be tilted at an angle of 42 degrees facing southwards towards the equator where sun rays are more direct all-year-round.
As far as local factors that could impede solar production go, Dreieich experiences some cloud cover throughout much of the year which could reduce sunlight reaching your panels especially during winter months when sunshine duration is already limited by short days. Additionally, buildings or trees may cast shadows on your panels depending on their location which would also limit their productivity.
To mitigate these issues and ensure greater energy production:
1) Choose a site for your installation where there's minimal shading throughout different times of day and seasons.
2) Regularly clean your panels to remove any dust or debris that could block sunlight.
3) Consider using more advanced solar panels that perform better under low light or cloudy conditions.
Overall, while Dreieich's location isn't perfect for solar energy, with the right installation and maintenance practices it can still be a viable source of renewable energy.
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 Dreieich
Seasonal solar PV output for Latitude: 50.0188, Longitude: 8.6956 (Dreieich, 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 Dreieich, Germany
To maximize your solar PV system's energy output in Dreieich, Germany (Lat/Long 50.0188, 8.6956) 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 Dreieich, 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 Dreieich, 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 Dreieich, 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 Dreieich, 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 Dreieich, Germany
Dreieich is located in the state of Hesse, Germany. The topography around Dreieich is relatively flat with slight undulations. It's situated on a plain that's part of the larger Rhine-Main area, which is characterized by its mix of urban areas, farmland and forests.
The region has a temperate seasonal climate, which means it does receive a substantial amount of sunlight throughout the year. However, it’s not as high as in some other parts of Germany like Bavaria or Baden-Wuerttemberg.
For large-scale solar PV installations, flat open spaces that receive good sunlight are ideal. In the case of Dreieich and its surroundings:
1) Farmlands: Some nearby agricultural lands could be used for solar PV installations without causing too much disruption to local farming activities.
2) Industrial zones: There are also several industrial areas around Dreieich where solar panels could be installed on rooftops or unused land.
3) Unused land: Any open unused land with good sun exposure would also be suitable for large-scale solar PV projects.
However, any potential site would require further detailed analysis including sun path analysis, soil investigation and environmental impact assessment before proceeding with installation. Also local regulations and policies related to renewable energy installation need to be considered.
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.
