The location in Grevenbroich, North Rhine-Westphalia, Germany is somewhat ideal for generating solar power. However, the effectiveness of a solar panel system here would vary throughout the year.
In simple terms, during summer and spring, you could expect good amounts of electricity from your solar panels. Specifically, in summer you'd get about 5.22 kilowatt-hours (kWh) per day for each kilowatt (kW) of installed solar capacity. In spring it's slightly less at around 4.34 kWh/day per kW.
However, autumn and winter are less productive seasons for solar energy generation at this location because there's less sunlight available due to shorter days and weather conditions like cloud cover or fog that can reduce sunlight intensity. You'd get around 2.31 kWh/day per kW in autumn and just about 1.14 kWh/day per kW in winter.
To maximize total yearly production from your panels at this location they should be tilted towards the south at an angle of approximately 43 degrees which aligns with sun’s path across sky over course of year.
As far as environmental or local factors that might affect how much energy you can generate using solar power here: The area is known to have cloudy weather frequently which reduces amount of direct sunlight reaching panels thereby reducing their output potential; also snowfall during winter could potentially cover up panels reducing their ability to generate electricity altogether until cleared off.
Preventative measures include installing systems that can tilt or track movement of sun so even on cloudy days some direct sunlight may still reach them; another option is having a system set up to automatically remove snow from panels ensuring they remain clear and able to produce as much electricity as possible even during snowy conditions.
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 Grevenbroich
Seasonal solar PV output for Latitude: 51.129, Longitude: 6.6344 (Grevenbroich, 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 Grevenbroich, Germany
To maximize your solar PV system's energy output in Grevenbroich, Germany (Lat/Long 51.129, 6.6344) 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 Grevenbroich, 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 Grevenbroich, 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 | 54° 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 Grevenbroich, 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 Grevenbroich, 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 Grevenbroich, Germany
Grevenbroich, Germany is located in the state of North Rhine-Westphalia and is characterized by a relatively flat topography. The area surrounding Grevenbroich consists primarily of plains with some minor hills. This region has an average altitude of about 50 meters above sea level.
The flat lands around Grevenbroich make it suitable for large-scale solar PV installations. Given that solar panels perform best when they are not obstructed from direct sunlight, these areas would be ideal due to their lack of significant elevation changes or mountainous terrain which could potentially cast shadows over the panels.
However, the suitability for large-scale solar PV also depends on other factors such as local climate (sunlight hours), land use regulations, environmental considerations and proximity to power grids for energy transmission. In terms of weather, this region does have cloudy days but still receives a decent amount of sunlight throughout the year making it viable for solar energy production.
One specific area nearby that could be suited to large scale Solar PV is "Garzweiler surface mine", a large open-pit coal mine near Grevenbroich which will eventually be shut down due to Germany's plan to phase out coal by 2038. This site could potentially be repurposed into a massive solar farm once mining operations cease.
It's important though before any project initiates proper feasibility studies should take place considering all aspects including economic viability, technical feasibility and social acceptance among others.
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.
