To put it simply, the location at Weinheim, Baden-Wurttemberg, Germany is fairly good for generating solar power throughout the year. However, the amount of electricity generated will vary with each season.
In summer and spring, you can expect to generate a good amount of electricity - 5.55 kilowatt hours (kWh) per day in summer and 4.57 kWh/day in spring for every kilowatt (kW) of solar installed. This means that these seasons are ideal times to get energy from your solar panels due to longer daylight hours and stronger sunlight.
On the other hand, autumn and winter will provide less output - only about 2.59 kWh/day in autumn and even lower at 1.24 kWh/day during winter for each kW installed because there's less sunlight available due to shorter days.
For maximum year-round production from your solar photovoltaic (PV) system at this location, it's best if you tilt your panels towards south at an angle of 42 degrees as this would make sure they're facing directly towards the sun when it is highest in sky which happens around noon time.
However, there could be some local factors that might affect how much energy you can produce from your solar PV system such as weather conditions like cloudy or foggy days reducing sunlight availability or environmental factors like buildings or trees casting shadows over your panels thus blocking direct sunlight.
If these issues are significant enough then you may want to consider taking some preventative measures when installing your system such as carefully choosing where exactly on property you install them so they're not obstructed by any potential shade-causing objects or maybe even considering using special technology that helps increase efficiency on cloudy days.
Also keep in mind maintenance activities like regularly cleaning dust off panels so they can capture maximum possible amount of light all times which will ensure greater energy production overall.
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 Weinheim
Seasonal solar PV output for Latitude: 49.5446, Longitude: 8.6711 (Weinheim, 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 Weinheim, Germany
To maximize your solar PV system's energy output in Weinheim, Germany (Lat/Long 49.5446, 8.6711) 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 Weinheim, 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 Weinheim, 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 Weinheim, 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 Weinheim, 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 Weinheim, Germany
Weinheim, Germany is located in the Rhine-Neckar Metropolitan Region and is characterized by a mixed topography. It lies at the foot of the Odenwald, a low mountain range, with gentle hills and valleys. The region also has several forests and bodies of water.
Considering solar PV installations, flat or gently sloping areas are most suitable as they receive maximum sunlight exposure. In Weinheim's case, open spaces like agricultural lands or unused industrial sites could be potential locations for large-scale solar PV systems.
However, it's important to note that factors other than topography play crucial roles in determining suitability for solar installations - these include local climate (amount of sunshine), land use restrictions and environmental considerations. For example, even if an area is geographically suitable, it may not be legally permissible or environmentally sustainable to install a large-scale solar farm there.
Therefore a detailed feasibility study would be required to identify specific locations within Weinheim or its surroundings that are best suited for large-scale solar PV installations. This study should consider multiple factors including geographical/topographical features but also legal constraints (e.g., zoning laws) and potential environmental impacts.
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.
