Solar PV Analysis of Herborn, Germany
Herborn, a town in Hesse, Germany, presents a mixed outlook for solar PV energy generation throughout the year. Located in the Northern Temperate Zone, this area experiences distinct seasonal variations in solar energy production.
Seasonal Solar Performance
Summer stands out as the most productive season, with an impressive 5.25 kWh per day for each kW of installed solar capacity. Spring follows closely, generating 4.29 kWh daily. These seasons offer the best conditions for solar energy production, with longer daylight hours and generally clearer skies.
Autumn sees a significant drop in production, yielding 2.34 kWh per day. Winter experiences the lowest output, with only 1.11 kWh daily, due to shorter days and less direct sunlight.
Optimal Panel Installation
For fixed panel installations in Herborn, the ideal tilt angle is 43 degrees facing South. This angle maximizes year-round solar energy capture, taking into account the town's latitude and seasonal sun positions.
Environmental Considerations
While Herborn's location is generally favorable for solar energy, there are some factors that could impact production:
- Cloud cover: The region experiences significant cloud cover, especially in autumn and winter, which can reduce solar output.
- Snow: Winter snowfall can temporarily cover panels, reducing efficiency.
To mitigate these issues, consider installing panels at a steeper angle to encourage snow sliding off and use high-efficiency panels that perform better in low-light conditions. Regular maintenance, including snow removal, can also help maintain optimal performance.
In conclusion, while Herborn's location presents challenges, particularly in winter, it still offers good potential for solar energy production, especially during spring and summer months. With proper installation and maintenance, solar PV can be a viable renewable energy option in this German town.
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 Herborn
Seasonal solar PV output for Latitude: 50.6841, Longitude: 8.3053 (Herborn, 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 Herborn, Germany
To maximize your solar PV system's energy output in Herborn, Germany (Lat/Long 50.6841, 8.3053) 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 Herborn, 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 Herborn, 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 Herborn, 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 Herborn, 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 Herborn, Germany
The area around Herborn, Germany, is characterized by a diverse and picturesque landscape typical of the central German region. Herborn itself is nestled in the Dill valley, surrounded by gently rolling hills and forested areas. The topography is generally considered hilly, with elevations ranging from about 200 to 400 meters above sea level in the immediate vicinity.
The surrounding landscape is a mix of small valleys, plateaus, and hillsides. The Dill River flows through the area, carving out a valley that has influenced the local topography. To the east and west of Herborn, the terrain becomes more elevated, with some steeper hillsides covered in dense forests. These wooded areas are part of the larger Westerwald region, known for its natural beauty and varied terrain.
When considering areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, several factors come into play. Ideally, solar farms require relatively flat or gently sloping land with good exposure to sunlight throughout the day. Based on the topography around Herborn, the most suitable areas for solar PV would likely be found on the plateaus and gentler hillsides, particularly those with a southern exposure.
The agricultural areas to the north and northeast of Herborn, where the landscape becomes slightly flatter, could potentially offer good locations for solar farms. These areas often have larger open spaces that are not heavily forested, which is advantageous for solar installations. Additionally, some of the cleared hilltops or south-facing slopes in the region might be suitable, provided they are not too steep and are easily accessible for construction and maintenance.
However, it's important to note that the hilly nature of the region and the presence of forests may limit the availability of large, contiguous areas for extensive solar farms. Any potential sites would need to be carefully evaluated for their specific topography, sun exposure, and environmental impact before being considered for large-scale solar PV development.
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.
