Solar PV Analysis of Bretzenheim, Germany
The location at Bretzenheim, Rheinland-Pfalz, Germany can produce a decent amount of energy from solar power throughout the year, but it's not ideal. The best time to generate solar power here is in the summer when you can expect about 5.33 kilowatt-hours (kWh) of electricity per day for each kilowatt (kW) of installed solar panels. Spring is also good with an expected output of 4.63 kWh/day per kW.
However, during autumn and winter, the performance drops quite significantly to 2.60 kWh/day per kW and 1.22 kWh/day per kW respectively due to shorter days and less sunlight.
For a fixed panel installation in this location, tilting your panels at an angle of 42 degrees towards the south will give you maximum total production all year round.
In terms of local factors that might affect solar production at this location; weather conditions such as cloud cover and fog could reduce sunlight reaching your panels especially during autumn and winter months which already have lower sun exposure compared to other seasons.
To prevent these issues from affecting your energy production too much; consider installing tracking systems that move your panels to follow the sun throughout the day or using more advanced types of solar cells that are better able to convert low light into electricity. Regular cleaning of panels can also help ensure they're working as efficiently as possible by removing any dust or debris that might block sunlight.
Also remember that while these measures may increase efficiency somewhat, they won't change seasonal variations in sunlight – so be prepared for lower output during autumn and winter no matter what steps you take.
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 Bretzenheim
Seasonal solar PV output for Latitude: 49.8753, Longitude: 7.9024 (Bretzenheim, 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 Bretzenheim, Germany
To maximize your solar PV system's energy output in Bretzenheim, Germany (Lat/Long 49.8753, 7.9024) 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 Bretzenheim, 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 Bretzenheim, 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 Bretzenheim, 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 Bretzenheim, 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 Bretzenheim, Germany
Bretzenheim is located in the Rhineland-Palatinate state of Germany. The topography around Bretzenheim is generally characterized by rolling hills, valleys and flat plains with a mix of agricultural fields, forests and urban areas. The region has a temperate seasonal climate.
For large-scale solar PV installations, open and relatively flat areas are ideal to maximize sun exposure throughout the day. In this regard, the agricultural fields surrounding Bretzenheim could be potential sites for such projects as they offer ample space with good sun exposure. However, it's important to consider that using productive farmland for solar projects can lead to conflicts over land use.
Another potential area could be rooftops in urban or industrial zones within and around Bretzenheim where there are large buildings or warehouses. These spaces often go unused but have great potential for solar energy production.
It's also worth noting that while the Rhineland-Palatinate region does receive a fair amount of sunlight compared to other parts of Germany (around 1500-1700 hours per year), it doesn't compare to more southern regions like Bavaria which gets up to 2000 hours per year.
Lastly, any decision on where to locate large-scale solar PV should take into account factors such as local regulations related to renewable energy development, grid connectivity infrastructure and environmental considerations among others.
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.
