Solar PV Analysis of Erwitte, Germany
Erwitte, North Rhine-Westphalia, Germany is a decent location for generating energy via solar PV year-round. However, the amount of energy produced can vary greatly depending on the season.
In simpler terms, if you were to install a solar power system in Erwitte, you could expect it to work best during summer and spring when it would generate around 5.03kWh/day and 4.14kWh/day per kW of installed solar respectively. This means that these are the ideal times of year to generate solar at this location because there's more sunlight.
During autumn and winter though, your system wouldn't be quite as efficient due to less sunlight available – producing about 2.21kWh/day and 1.03kWh/day per kW respectively.
To get the most out of your solar panels throughout the year in Erwitte, they should be tilted at an angle of 44 degrees facing southwards - this helps capture maximum sunlight.
As for any factors that might affect how well your panels work: weather conditions such as heavy snowfall or extended periods of cloudiness could reduce their efficiency by blocking sunlight from reaching them directly - which is something common in this region during winter months especially.
One way around this would be installing devices that automatically adjust panel angles based on sun position or even using heated panels to melt any accumulated snow off them quickly; ensuring they are cleaned regularly also helps maintain their efficiency levels high by removing dust or dirt build-up that may block some light too.
Also consider potential shading from nearby structures or trees which can limit exposure to direct sunlight – so choosing an installation site with minimal obstructions would benefit overall production levels significantly here too.
Remember though: while these measures can help maximize output they will also increase initial investment costs; but over time better performance should help recover these extra expenses through higher savings on electricity bills thanks to greater self-generated power use.
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 Erwitte
Seasonal solar PV output for Latitude: 51.6067, Longitude: 8.2943 (Erwitte, 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 Erwitte, Germany
To maximize your solar PV system's energy output in Erwitte, Germany (Lat/Long 51.6067, 8.2943) 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 Erwitte, 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 Erwitte, 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 |
|---|---|---|---|
| 35° South in Summer | 54° 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 Erwitte, 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 Erwitte, 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 Erwitte, Germany
Erwitte, Germany is located in the North Rhine-Westphalia region. The area's topography is generally flat to gently rolling hills, with some forested areas. This type of terrain could be suitable for solar PV installations.
The most suitable areas for large-scale solar PV would be open and flat lands that receive a good amount of sunlight throughout the year. Agricultural fields or unused industrial zones could potentially be converted into solar farms.
However, it should be noted that any large-scale project like this would need to consider not just the physical suitability of the land but also local regulations, environmental impact assessments and potential effects on local communities.
Specifically in Germany, there are restrictions on using arable land for solar power generation due to laws protecting agricultural spaces. Therefore brownfield sites (previously developed sites that are not currently in use) may offer better opportunities for such development.
Additionally, while Erwitte does receive a fair amount of sunshine by German standards (around 1,500 hours per year), it does not have as high levels of irradiation as southern parts of the country or other more southerly countries in Europe.
Therefore careful consideration would need to be given to whether conditions are sufficiently favorable economically for large scale solar PV compared with other locations or forms of renewable energy generation.
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.
