Solar PV Analysis of Siegsdorf, Germany
Siegsdorf, Bavaria, Germany is a decent location for generating solar energy throughout the year. However, the effectiveness varies significantly from season to season due to its location in the Northern Temperate Zone.
In simple terms, if you install a 1 kW solar panel system there, you can expect it to generate different amounts of electricity during each season. In summer, it would produce around 5.79 kWh per day - this is when your system will be at its most productive because of longer daylight hours and more intense sunlight. In autumn and spring, production drops to about 3.08 kWh/day and 4.34 kWh/day respectively as the days become shorter and sunshine less intense compared with summer.
Winter sees the lowest production rate at around 1.74 kWh/day due to short daylight hours and often overcast skies in Siegsdorf during this time of year.
To maximize your yearly solar energy output at this location, it's recommended that you tilt your panels at an angle of approximately 41 degrees facing southwards (towards the sun). This positioning allows for optimal exposure to sunlight throughout all seasons.
There could be factors specific to Siegsdorf that might affect solar production such as local weather patterns (like frequent fog or cloud cover), topography (like mountains or tall buildings causing shading), or environmental regulations protecting certain areas from development.
In order to prevent these potential issues from reducing your solar panel efficiency:
- Install panels in an area with minimal shading.
- If fog or clouds are common in Siegsdorf; consider high-efficiency panels which can perform better under these conditions.
- Comply with local environmental regulations by choosing appropriate sites for installation avoiding protected areas.
Remember that while these measures can help increase efficiency they cannot completely overcome limitations imposed by seasonal changes in sunlight availability inherent in Siegsdorf's geographical location.
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 Siegsdorf
Seasonal solar PV output for Latitude: 47.8262, Longitude: 12.6461 (Siegsdorf, 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 41° South in Siegsdorf, Germany
To maximize your solar PV system's energy output in Siegsdorf, Germany (Lat/Long 47.8262, 12.6461) throughout the year, you should tilt your panels at an angle of 41° 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 Siegsdorf, 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 Siegsdorf, Germany. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 41° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 31° South in Summer | 51° South in Autumn | 61° South in Winter | 40° 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 Siegsdorf, 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 Siegsdorf, 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 Siegsdorf, Germany
Siegsdorf is located in the southeastern part of Germany, in the state of Bavaria. The topography around Siegsdorf is generally hilly with several mountains and valleys as it's situated near the edge of the Alps. There are also several forests and bodies of water such as lakes and rivers.
For large-scale solar PV installations, flat or gently sloping areas are ideal to maximize exposure to sunlight and minimize installation difficulties. Therefore, open fields or cleared lands with minimal shading from trees or buildings would be most suitable in this region.
While Bavaria does have a fair amount of sunshine compared to other German states, one must consider that Siegsdorf's location near the Alps might mean more cloud cover and less direct sunlight than flatter regions. However, advanced solar technology can still harness energy effectively under diffuse light conditions.
In terms of specific nearby areas for large-scale solar PV:
1. Chiemgau Plains: This area has relatively flat terrain which could be suitable for large-scale solar installations.
2. North-East towards Traunstein: The land here tends to be flatter compared to other directions.
3. Unused industrial land: If there are any disused industrial sites nearby, these could potentially be repurposed for renewable energy projects.
However, it's important to note that any potential site would need a detailed assessment considering not just topography but also factors like local climate conditions (sunlight hours), land use restrictions, proximity to power grids etc., before deciding on its suitability for a large scale solar PV project.
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.
