Solar PV Analysis of Schwetzingen, Germany
The location at Schwetzingen, Germany is moderately ideal for generating energy via solar PV year-round. The amount of sunlight that this location receives varies throughout the year, with the highest amount of energy being produced in the summer (5.55kWh/day) and spring (4.57kWh/day). This means that these are the most ideal times of year to generate solar power at this location.
During autumn and winter, less sunlight is received due to shorter days and lower sun angles, resulting in less energy production (2.59kWh/day in autumn and 1.24kWh/day in winter). However, by tilting solar panels at an angle of 42 degrees South, you can maximise total annual production from your solar PV system.
As for local factors that could affect solar production at this location; Schwetzingen is located on a plain area with no significant topographical features like mountains or valleys that could obstruct sunlight. However, Germany's weather can be quite cloudy especially during autumn and winter which might reduce the efficiency of your solar panels.
To combat these potential issues when installing your panels:
- You may want to consider using high-efficiency panels which perform better under low light conditions.
- Regular cleaning and maintenance will also help ensure optimal performance as dirt or snow accumulation on the panel surface can block sunlight.
- A tracking system could also be used so that your panels follow the sun’s path across sky maximizing their exposure to sunlight throughout day.
In conclusion, while there are some challenges due to seasonal variations in sunlight availability and weather conditions like cloudiness or snowfall; with appropriate planning such as optimal panel tilt angle setting & regular maintenance – it's possible to produce a good amount of energy from a solar PV system installed at Schwetizingen all year round.
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 Schwetzingen
Seasonal solar PV output for Latitude: 49.3821, Longitude: 8.5918 (Schwetzingen, 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 Schwetzingen, Germany
To maximize your solar PV system's energy output in Schwetzingen, Germany (Lat/Long 49.3821, 8.5918) 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 Schwetzingen, 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 Schwetzingen, 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 Schwetzingen, 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 Schwetzingen, 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 Schwetzingen, Germany
Schwetzingen is located in the Rhine-Neckar Metropolitan Region in Germany. The topography of this region is relatively flat with some gentle rolling hills, making it potentially suitable for solar PV installations. The area is characterized by a mix of urban areas, agricultural land and forests.
The most suitable locations for large-scale solar PV installations would likely be on the less productive agricultural lands or unused open spaces to avoid competition with food production or deforestation. These areas typically have good sun exposure and are relatively flat which makes installation easier.
It's also important to note that suitability for solar PV also depends on factors like local climate, sunlight levels and existing infrastructure for power transmission. As such, a detailed site-specific analysis would be needed to identify the best spots.
Additionally, rooftop installations on large buildings in urban or industrial areas could also be an option as they don't require additional land use.
Please note that any renewable energy project must adhere to local laws and regulations including environmental impact assessments and public consultations.
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.
