Solar PV Analysis of Holzkirchen, Germany
The location at Holzkirchen, Bavaria, Germany is fairly good for generating energy through solar panels all year round. However, the amount of electricity produced varies depending on the season.
In simple terms, a solar panel system here can produce an average of 5.65 units of electricity per day in summer for every unit of solar panel installed. This output drops to 3.10 units in autumn and further down to 1.75 units in winter before going up again to 4.63 units in spring.
This means that you'll get the most out of your solar panels during summer and spring when there's more sunlight available throughout the day compared to autumn and winter.
To make sure you're getting as much power as possible from your solar panels throughout the year, they should be tilted at an angle facing southwards by about 41 degrees from horizontal level.
As for local factors that might affect how much energy you can get from your solar panels; weather conditions like heavy snowfall or long periods with cloudy skies could reduce their efficiency because they block sunlight from reaching the panels directly.
To prevent this, it would be helpful if you can install a system that allows easy removal or melting off any snow accumulation on top of them during winter months while keeping them clean from dust and other debris all year round will also ensure maximum light absorption.
Another thing worth noting is ensuring there are no tall buildings or trees around which could cast shadows onto your panels especially during peak hours when sun is high up hence reducing their effectiveness even further.
Lastly, regular maintenance checks by professionals will help identify any issues early enough before they become major problems affecting overall performance over time leading to lower than expected power production levels despite having invested heavily into installing these systems initially.
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 Holzkirchen
Seasonal solar PV output for Latitude: 47.8781, Longitude: 11.7032 (Holzkirchen, 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 Holzkirchen, Germany
To maximize your solar PV system's energy output in Holzkirchen, Germany (Lat/Long 47.8781, 11.7032) 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 Holzkirchen, 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 Holzkirchen, 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 | 62° 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 Holzkirchen, 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 Holzkirchen, 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 Holzkirchen, Germany
Holzkirchen is located in the southern part of Germany, in the state of Bavaria. The topography around Holzkirchen is characterized by a mix of flat and hilly terrain with some forested areas. It's surrounded by farmland, small lakes and rivers. The region is part of the Alpine Foreland, so it has a mixture of lowlands and highlands with elevations ranging from 600 to 700 meters above sea level.
Regarding solar PV installations, flat terrains are generally more suitable as they require less site preparation work compared to sloped or hilly terrains. Therefore, the agricultural lands around Holzkirchen could potentially be suitable for large-scale solar PV installations given their relatively flat topography.
However, other factors such as local climate (amount of sunlight), land use regulations (whether solar farms are allowed on farmland), proximity to power grids (for electricity transmission) and environmental considerations should also be taken into account when determining suitability for solar PV installations.
Lastly, one should conduct an actual site assessment or feasibility study before deciding on any potential locations for large-scale solar PV projects.
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.
