Solar PV Analysis of Vaihingen An Der Enz, Germany
The location at Vaihingen an der Enz, Germany is suitable for generating solar energy throughout the year, but it's not ideal all the time. The amount of energy you can generate from solar panels changes with each season.
In simple terms, a solar panel will produce the most electricity in summer. This is because there are more hours of sunlight and the sun is higher in the sky. In this location, you could expect about 5.59 kilowatt-hours per day for each kilowatt of installed solar power during summer.
In autumn and spring, there's less sunlight so your panels won't make as much electricity - around 2.81 kWh/day in autumn and 4.56 kWh/day in spring per kW of installed solar.
Winter has even less sunlight than autumn or spring - only about 1.37 kWh/day per kW of installed solar - so this would be when your panels produce the least amount of power.
To get as much power as possible from your panels all year round, they should be tilted at an angle facing south by 42 degrees at this location.
Now let's talk about factors that might prevent your panels from working well here:
Germany has a temperate seasonal climate dominated by humid westerly winds which means it can often be cloudy which reduces how much light reaches your panel; however Vaihingen an der Enz does have many clear days throughout the year too so overall it shouldn't greatly affect production.
The area also has varied topography with hills and valleys that could potentially block some sunlight depending on where exactly you install your panels.
Snowfall during winter might cover up your panels temporarily reducing their production until cleared off; but snow also reflects light which can sometimes actually increase production if conditions are right.
Preventative measures to ensure greater energy production include choosing a site for installation that gets maximum exposure to direct sunlight without obstructions such as hills or buildings. Regular maintenance and cleaning of the panels to remove dust, leaves or snow can also help to ensure they work at their best.
In conclusion, while not ideal year-round due to seasonal changes in sunlight and potential weather and topographical challenges, with proper installation and maintenance, Vaihingen an der Enz is a suitable location for generating solar energy.
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 Vaihingen An Der Enz
Seasonal solar PV output for Latitude: 48.934, Longitude: 8.9527 (Vaihingen An Der Enz, 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 Vaihingen An Der Enz, Germany
To maximize your solar PV system's energy output in Vaihingen An Der Enz, Germany (Lat/Long 48.934, 8.9527) 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 Vaihingen An Der Enz, 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 Vaihingen An Der Enz, 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 |
|---|---|---|---|
| 32° South in Summer | 52° South in Autumn | 62° South in Winter | 41° 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 Vaihingen An Der Enz, 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 Vaihingen An Der Enz, 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 Vaihingen An Der Enz, Germany
Vaihingen an der Enz is located in the southwestern part of Germany, within the state of Baden-Württemberg. The topography of this area is generally hilly, characterized by vineyards and forests. The region has a mix of rural and urban landscapes with some flat areas that could be suitable for solar PV installations.
The region's climate is temperate seasonal, which means it has moderate sunshine hours making it viable for solar power generation. However, the efficiency might not be as high as in sunnier regions.
For large-scale solar PV installations, open and relatively flat areas are typically preferred to minimize installation costs and maximize exposure to sunlight. In Vaihingen an der Enz area, these could potentially include agricultural lands or other open spaces that are not shaded by hills or forests.
However, any decision on locations for large-scale solar PV should take into account a variety of factors including land use regulations, environmental impact assessments, proximity to existing power grids for easy transmission and distribution of generated electricity among others. It's also important to consider local community views on such projects.
Lastly but importantly, technological advancements have made it possible to install solar panels on slopes or uneven terrains too but at a higher cost compared to flat lands due to increased complexity in installation.
Therefore detailed feasibility studies would need to be conducted before deciding on specific sites for large-scale solar PV installations around Vaihingen an der Enz.
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.
