Achim, Lower Saxony, Germany, located at latitude 53.0177 and longitude 9.0235, presents a mixed picture for solar PV energy generation throughout the year. This northern temperate zone location experiences significant seasonal variations in solar output, which impacts the overall efficiency of solar installations.
Seasonal Solar Performance
The solar energy production in Achim follows a predictable pattern aligned with the changing seasons. Summer months offer the highest potential, with an average daily output of 5.26 kWh per kW of installed solar capacity. Spring follows as the second most productive season, generating 4.09 kWh/day. Autumn sees a considerable drop to 1.98 kWh/day, while winter experiences the lowest output at merely 0.91 kWh/day.
These figures indicate that solar energy generation in Achim is most effective from late spring through early autumn. During this period, longer daylight hours and higher sun angles contribute to increased solar panel efficiency.
Optimal Panel Installation
To maximize year-round solar energy production in Achim, fixed solar panels should be installed at a tilt angle of 44 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, balancing the low winter sun angle with the higher summer sun position.
Environmental and Weather Considerations
Several factors can impact solar energy production in Achim:
- Cloud cover: The region experiences frequent cloudy days, especially in autumn and winter, which can significantly reduce solar output.
- Short winter days: Due to its northern latitude, Achim has very short days in winter, limiting the amount of sunlight available for energy production.
To mitigate these challenges, consider the following measures:
- Use high-efficiency solar panels that perform well in low-light conditions.
- Implement a robust cleaning schedule to remove any dirt or snow accumulation on panels.
- Consider a hybrid system that combines solar with other renewable energy sources to ensure consistent power supply year-round.
While Achim's location presents some challenges for solar energy production, particularly during the winter months, proper system design and maintenance can still make solar PV a viable option for supplementing energy needs, especially during the more productive summer and spring seasons.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Achim
Seasonal solar PV output for Latitude: 53.0177, Longitude: 9.0235 (Achim, 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 44° South in Achim, Germany
To maximize your solar PV system's energy output in Achim, Germany (Lat/Long 53.0177, 9.0235) throughout the year, you should tilt your panels at an angle of 44° 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 Achim, 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 Achim, Germany. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 44° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 36° South in Summer | 55° South in Autumn | 66° South in Winter | 45° 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 Achim, 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 Achim, 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 Achim, Germany
The area surrounding Achim, Germany, located at coordinates 53.0177°N, 9.0235°E, is characterized by a predominantly flat landscape typical of northern Germany's lowlands. This region, known as the North German Plain, features gentle rolling hills and expansive open spaces. The terrain is largely shaped by glacial activity during the last ice age, resulting in a mix of sandy soils, scattered woodlands, and agricultural fields.
Local Topography
Achim itself sits on the eastern bank of the Weser River, which meanders through the landscape and has played a significant role in shaping the local topography. The river valley is relatively wide and flat, with occasional gentle slopes leading up to slightly higher ground. To the east and north of Achim, the land gradually rises, forming subtle hills and ridges that rarely exceed 50 meters in elevation. The area is dotted with small forests and copses, interspersed with expansive farmland and meadows. Numerous small streams and drainage channels crisscross the landscape, contributing to the region's rich agricultural heritage. The soil in this area is primarily composed of glacial deposits, including sand, gravel, and loam, which influence the local vegetation and land use.Potential for Solar PV
When considering areas near Achim that would be most suited for large-scale solar PV installations, several factors come into play. The relatively flat terrain in much of the surrounding region offers advantages for solar farm development. Areas to the east and southeast of Achim, where the land rises slightly, could potentially provide optimal sites for solar arrays. These gently sloping areas may receive more direct sunlight throughout the day and could be less prone to shadowing effects. Additionally, the open agricultural lands that dominate the landscape around Achim present opportunities for solar development, as they often have fewer obstructions and may be more easily repurposed. However, it's important to note that the region's northern latitude means that solar irradiance is generally lower compared to more southern locations. This factor would need to be carefully considered in the planning and design of any large-scale solar PV project. Furthermore, the proximity to the Weser River and its tributaries may introduce considerations related to flood risk and soil stability in some areas. Ultimately, detailed site-specific assessments would be necessary to determine the most suitable locations for solar PV installations near Achim. These assessments would need to take into account factors such as local zoning regulations, grid connectivity, and environmental impact, in addition to the topographical considerations discussed here.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.
