Solar PV Analysis of Pirmasens, Germany
The location at Pirmasens, Rheinland-Pfalz, Germany is fairly good for generating energy using solar panels throughout the year. However, the amount of energy produced varies depending on the season.
During summer and spring, you can expect to generate a lot of electricity with 5.33 kilowatt-hours (kWh) per day in summer and 4.63 kWh/day in spring for each kilowatt (kW) of installed solar power. This means these are the best times to generate solar power at this location because there's more sunlight during these seasons.
In contrast, autumn and winter produce less electricity with only 2.60 kWh/day in autumn and even less during winter with just 1.22 kWh/day per kW of installed solar power due to shorter daylight hours and less intense sunlight.
For a fixed panel installation at this location, tilting your panels at an angle of 42 degrees towards South will maximize total year-round production from your solar PV system as it allows the panels to catch as much sunlight as possible throughout different times of the day and different seasons.
As for factors that could impede solar production at this location - weather conditions such as overcast days or snowfall could reduce output by blocking sunlight from reaching your panels. Regular cleaning and maintenance can help ensure greater energy production by removing any obstructions like dust or snow that might block sunlight from reaching your panels.
Additionally, potential shading from nearby buildings or trees should be considered when installing your system since they can also block direct sunlight especially during morning or late afternoon hours when the sun is low in the sky.
Overall though, while there are some challenges associated with producing solar energy in Pirmasens due to seasonal variations in sunshine levels - if you're prepared to manage these issues effectively then it's certainly feasible to harness renewable energy through PV technology here 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 Pirmasens
Seasonal solar PV output for Latitude: 49.2154, Longitude: 7.6315 (Pirmasens, 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 Pirmasens, Germany
To maximize your solar PV system's energy output in Pirmasens, Germany (Lat/Long 49.2154, 7.6315) 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 Pirmasens, 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 Pirmasens, 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 | 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 Pirmasens, 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 Pirmasens, 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 Pirmasens, Germany
Pirmasens, Germany is located in the southwest part of the country and is characterized by a hilly landscape with forested areas, as it lies on the edge of Palatinate Forest. It's situated in a valley surrounded by low-lying hills.
When considering large-scale solar PV installations, factors such as sunlight hours, land availability and slope of land should be considered. While Pirmasens does have relatively high annual sunshine hours compared to other parts of Germany (around 1600 - 1700 hours), its hilly terrain might not be ideal for large-scale flat solar farms.
However, Pirmasens' rooftops could be well suited for smaller scale solar panel installations. Also, there are some flatter open spaces around nearby towns like Zweibrücken or Homburg that could potentially accommodate larger solar farms.
It's also worth noting that Germany has been very successful in integrating renewable energy sources into their grid even with less than optimal natural conditions, so while Pirmasens may not have the most suitable topography for large scale solar power generation compared to sunnier and flatter regions elsewhere in the world; innovative solutions can still make it feasible here too.
Lastly, any specific project would require detailed site surveys and feasibility studies to ensure suitability.
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.
