Solar PV Analysis of Belm, Germany
The location at Belm, Lower Saxony, Germany is decent for generating energy via solar photovoltaic (PV) systems year-round. However, it's not perfect due to its seasonal variations in sunlight intensity.
During summer and spring, the area receives good sunlight with an average electricity output of 5.11 kilowatt-hours per day (kWh/day) and 4.21 kWh/day per kilowatt of installed solar respectively. This makes these seasons ideal for harnessing solar power.
Autumn sees a significant drop in sunlight intensity with an average output of just 2.13 kWh/day per kW of installed solar panels, while winter has the lowest productivity rate with an average daily output of only 0.98 kWh/day per kW.
To maximize total year-round production from a fixed panel installation at this location, the panels should be tilted at a south-facing angle of approximately 44 degrees.
However, there are some local factors that could potentially hinder optimal solar production in this region:
1. Weather conditions: The region experiences considerable cloud cover especially during autumn and winter which can reduce the amount of sunlight reaching the panels.
Preventative Measure: Using high-efficiency PV modules that can perform well even under low-light conditions may help improve energy production during cloudy days.
2. Snowfall: In winter months snow accumulation on solar panels can block incoming light thereby reducing their efficiency.
Preventative Measure: Panels can be installed at steeper angles to prevent snow build-up or regularly cleared off manually if safe to do so.
3. Vegetation/Buildings: Shadows cast by nearby buildings or tall trees could also affect panel performance by blocking direct sunlight.
Preventive Measure: Selecting a site devoid of such obstructions or trimming vegetation around your installation site would ensure greater exposure to sunlight.
In conclusion, although Belm does have potential for effective use of Solar PV systems throughout most of the year, careful consideration should be given to installation and maintenance factors to ensure optimal energy production.
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 Belm
Seasonal solar PV output for Latitude: 52.3015, Longitude: 8.1294 (Belm, 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 Belm, Germany
To maximize your solar PV system's energy output in Belm, Germany (Lat/Long 52.3015, 8.1294) 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 Belm, 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 Belm, 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 | 65° South in Winter | 44° 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 Belm, 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 Belm, 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 Belm, Germany
Belm is located in the Lower Saxony region of Germany. The topography around Belm is generally flat to gently rolling, typical of the North German Plain. It is a mix of agricultural lands, forests, and built-up areas.
Large-scale solar PV installations require large open spaces with minimal shading and good sun exposure. Considering this, the most suitable areas nearby for large-scale solar PV would likely be:
1) Unused or less productive agricultural land: Given that a significant part of the area around Belm is used for agriculture, some of these lands could potentially be repurposed for solar power generation. However, it's important to consider potential impacts on local food production and biodiversity.
2) Industrial zones or brownfield sites: If there are any disused industrial sites or other brownfield lands in or near Belm, these could also be suitable locations for solar farms.
3) Rooftops: Large buildings such as warehouses or factories often have expansive rooftops that can accommodate many solar panels.
4) Along transportation corridors: Highways and railways often have adjacent strips of land that can be used for installing photovoltaic panels without interfering with traffic flow.
Ultimately, suitability will depend on specific factors like local zoning regulations, availability and cost of land, connection to power grid infrastructure etc., which need to be examined in detail before making a decision.
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.
