Gelsenkirchen, Germany is a decent location for solar energy generation, but it's not ideal. The amount of energy you can get from solar panels changes with the seasons. In the summer, each kilowatt of installed solar can generate about 5.22 kilowatt-hours per day. This drops to 2.31 in the autumn and even lower to 1.14 in winter before rising again to 4.34 in spring.
So, if you're planning on using solar power year-round at this location, you'll get most of your energy in the summer and spring months while generating significantly less during autumn and winter due to shorter daylight hours and lower sun angles.
If you're installing fixed panels at this location, tilting them at an angle of about 44 degrees towards south would help maximize total annual production from your photovoltaic system because it aligns better with the path of the sun across the sky throughout different seasons.
As far as local factors that could affect solar production are concerned, Gelsenkirchen is located in a region that experiences significant cloud cover throughout much of the year which might reduce sunlight availability for panels; however this has been taken into account already when calculating average daily outputs above.
In addition to cloud cover, snowfall during winter could also potentially cover up your panels and impede their ability to generate electricity; so one preventative measure would be regular maintenance including clearing snow off your panels after heavy snowfalls during winter months.
Furthermore, considering topography or landscape features such as tall buildings or trees that might cast shadows on your installation site could also be important because they can block direct sunlight from reaching your panels especially during low-sun-angle periods like early morning or late afternoon hours; hence choosing an unobstructed site for installation would help ensure greater energy production overall.
Lastly remember these figures are averages so actual output may vary depending on specific weather conditions each day/season.
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 Gelsenkirchen
Seasonal solar PV output for Latitude: 51.5085, Longitude: 7.087 (Gelsenkirchen, 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 44° South in Gelsenkirchen, Germany
To maximize your solar PV system's energy output in Gelsenkirchen, Germany (Lat/Long 51.5085, 7.087) throughout the year, you should tilt your panels at an angle of 44° 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 Gelsenkirchen, 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 Gelsenkirchen, Germany. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 44° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 35° South in Summer | 54° South in Autumn | 64° South in Winter | 44° 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 Gelsenkirchen, 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 Gelsenkirchen, 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 Gelsenkirchen, Germany
Gelsenkirchen, Germany is located in the North Rhine-Westphalia region of western Germany. The topography of the area is relatively flat and low-lying, with some gently rolling hills. The region is part of the European Plain, which features fertile soils and a moderate climate.
The Ruhr River flows through Gelsenkirchen, and there are several smaller rivers and streams in the area as well. The city itself is heavily urbanized with significant industrial infrastructure due to its history as a coal mining center.
For large-scale solar PV installations, areas that are most suited would be those with ample sunlight exposure and minimal obstructions such as buildings or trees. Given Gelsenkirchen's flat terrain and northern latitude (51 degrees), solar panels would ideally be placed on south-facing slopes for maximum sun exposure throughout the day.
Potential locations could include open fields or unused industrial lands that have been reclaimed for renewable energy use. For instance, former coal mining sites could potentially be converted into solar farms if they are not suitable for other types of development due to soil contamination or other factors.
Moreover, rooftops of large industrial buildings or warehouses can also serve as potential sites for installing solar panels since these structures often have large surface areas that can accommodate multiple panels.
However, it's worth noting that any plans for large-scale solar PV installations would need to take into account local zoning regulations and community input before proceeding.
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.
