Solar PV Analysis of Heidenheim, Germany
The location at Heidenheim, Baden-Wurttemberg, Germany is decent for generating solar energy year-round, but not optimal. The best time to generate solar power here would be in the summer and spring when there's more sunlight. In the summer, you can expect to produce about 5.75kWh of electricity per day for every kW of installed solar panels. This decreases slightly in spring to about 4.59kWh/day.
However, during autumn and winter months, this amount reduces significantly due to shorter daylight hours and less intense sunlight - producing approximately 2.78kWh/day in autumn and just around 1.46kWh/day in winter.
To maximize total year-round production from your solar panels at this location, they should ideally be tilted towards the south at an angle of 41 degrees.
In terms of environmental or weather factors that could impede solar production at this location – Heidenheim experiences a moderate climate with cloudy days especially during colder seasons which could limit sun exposure on panels thereby reducing their output efficiency.
Preventative measures that can be taken when installing solar include ensuring clear access to sunlight without obstruction from trees or buildings; using high-quality PV modules known for good performance under low light conditions; incorporating a tracking system that allows your panels follow the sun’s path across the sky (though more expensive); or simply installing additional capacity to compensate for these less productive periods.
Lastly remember regular maintenance like cleaning off snow accumulation on panels during winter months will also help ensure greater energy production throughout the year.
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 Heidenheim
Seasonal solar PV output for Latitude: 48.6744, Longitude: 10.1307 (Heidenheim, 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 Heidenheim, Germany
To maximize your solar PV system's energy output in Heidenheim, Germany (Lat/Long 48.6744, 10.1307) 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 Heidenheim, 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 Heidenheim, 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 |
|---|---|---|---|
| 32° South in Summer | 51° South in Autumn | 62° South in Winter | 41° 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 Heidenheim, 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 Heidenheim, 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 Heidenheim, Germany
Heidenheim, Germany is located in a hilly area with the Swabian Jura mountain range to the south. The topography of this region is characterized by rolling hills, valleys and forests. The Härtsfeld region to the north-east of Heidenheim is also part of the Swabian Jura but it's more plateau-like.
For large-scale solar PV installations, flat or gently sloping areas are typically most suitable as they allow for easier installation and maintenance, and better sun exposure. Given this criteria, areas such as farmlands or open fields would be ideal. In Heidenheim's case, considering its hilly topography, solar panels could potentially be installed on south-facing slopes for optimal sunlight exposure.
However, other factors need to be taken into consideration when deciding on a location for large-scale solar PV installations like local climate (amount of sunlight), land use restrictions and proximity to power grids.
It should also be noted that despite not being ideally flat or gently sloping throughout its entirety; many parts of Germany have successfully implemented solar energy systems due to the country’s commitment towards renewable energy resources. Therefore with proper planning and design even less than ideal landscapes can house effective solar farms.
Remember though that comprehensive feasibility studies would need to be conducted before any decisions are made regarding specific locations for large-scale solar PV installations in or around Heidenheim.
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.
