Solar PV Analysis of Lohfelden, Germany
Lohfelden, a town in Hesse, Germany, presents a mixed picture for solar energy generation throughout the year. Located in the Northern Temperate Zone, this area experiences significant seasonal variations in solar output.
Seasonal Solar Performance
Summer stands out as the most productive season, with an impressive daily output of 5.03 kWh per kW of installed solar capacity. Spring follows closely behind, generating 4.14 kWh/day. However, the performance drops considerably during autumn, with only 2.21 kWh/day, and plummets to a mere 1.03 kWh/day in winter.
This stark contrast between seasons indicates that solar energy production in Lohfelden is highly dependent on the time of year. The long, sunny days of summer and spring provide ideal conditions for solar power generation, making these seasons particularly favorable for maximizing energy output.
Optimizing Panel Installation
To maximize year-round solar production at this location, fixed solar panels should be installed at a tilt angle of 43 degrees facing south. This optimal angle takes into account the location's latitude and the sun's position throughout the year, ensuring the best possible exposure to sunlight across all seasons.
Environmental Factors and Mitigation Strategies
While Lohfelden's location is generally suitable for solar energy production, there are some environmental factors that could potentially impact performance:
- Cloud cover: The region experiences frequent cloudy days, especially during autumn and winter, which can significantly reduce solar output.
- Snow accumulation: Winter snowfall can temporarily cover solar panels, reducing their efficiency.
To mitigate these issues, consider implementing the following measures:
- Use high-efficiency solar panels that perform well in low-light conditions.
- Install panels at a steeper angle to promote snow sliding off more easily.
- Implement a regular cleaning and maintenance schedule to ensure optimal performance.
By addressing these factors and optimizing panel installation, solar energy can be a viable and productive renewable energy source in Lohfelden, despite the seasonal variations in output.
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 Lohfelden
Seasonal solar PV output for Latitude: 51.2635, Longitude: 9.5372 (Lohfelden, 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 Lohfelden, Germany
To maximize your solar PV system's energy output in Lohfelden, Germany (Lat/Long 51.2635, 9.5372) 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 Lohfelden, 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 Lohfelden, 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 |
|---|---|---|---|
| 35° 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 Lohfelden, 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 Lohfelden, 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 Lohfelden, Germany
The area around Lohfelden, Germany, is characterized by gently rolling hills and shallow valleys typical of the central German landscape. Lohfelden itself sits in a relatively flat area, with elevations ranging from about 200 to 250 meters above sea level. The surrounding region gradually rises to the east and west, with some more pronounced hills and small forested areas scattered throughout the countryside.
To the north and east of Lohfelden, the land remains fairly level as it approaches the Fulda River valley. This area is primarily composed of agricultural fields and meadows, interspersed with small patches of woodland. To the south and west, the terrain becomes slightly more varied, with some steeper slopes and higher elevations reaching up to 300-350 meters in places.
When considering areas nearby that would be most suited to large-scale solar PV 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 of the region, the following areas near Lohfelden could be potential candidates:
- The open agricultural lands to the north and east of Lohfelden, which offer large, unobstructed spaces with minimal shading from hills or forests.
- Gently sloping hillsides facing south or southwest, which can be found in the more undulating terrain to the south and west of Lohfelden. These areas may provide optimal sun exposure throughout the day.
- Former industrial or brownfield sites in the broader region, which often offer large, flat areas suitable for solar installations while minimizing the impact on agricultural land.
It's important to note that while topography is a crucial factor in determining suitable locations for solar PV installations, other considerations such as proximity to power infrastructure, local zoning regulations, and environmental impact assessments would also play significant roles in the final site selection process.
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.
